The buffer shall be installed in a vertical position and located centrally with relation to the drop-test weight.
The buffer shall be secured by bolts in accordance with the manufacturer's drawings or by equivalent means to

(a) the foundation for buffers of the spring-return type

(b) the underside of the center of the test drop-weight for buffers of the gravity-return type

The centerline of the buffer, when secured in place, shall be vertical to within 0.25 mm (0.01 in.) in the stroke of the buffer.

The buffer test shall be on a production model or a buffer identical to the model to be produced. Modifications or special adjustments for the purpose of meeting the test requirements are prohibited.
The buffer, after being installed, shall be filled with oil to a level at or between the manufacturer's gauge line or lines. The oil shall conform to 2.22.4.9 and the data specified on the buffer marking plate.

After filling with oil, the procedure outlined below shall be followed to ensure that a constant oil level has been established.

(a) The buffer shall be fully compressed at slow speed, and shall then be allowed to return to its fully extended position and remain there for at least 10 min. The oil level shall then be checked.

(b) If the oil level as previously determined has changed, due to the elimination of entrapped air or due to the retention of air under pressure within the buffer, the change in level shall be noted and the procedure repeated until a constant oil level is obtained when the buffer is in its extended position.

(c) If the oil level tends to remain above the level to which it was filled, the air vents, if provided, should be checked for obstructions.

(d) When a constant oil level has been established, the level shall be adjusted to the manufacturer's lowest gauge line, and the exact level noted and recorded before making the drop tests hereinafter specified.

Each oil buffer with oil portings as submitted shall be subjected to tests for retardation, strength, oil leakage, plunger return, and lateral plunger movement, as hereinafter specified.
The following drop tests shall be made for each buffer porting specified in 8.3.2.2, from a height such that the striking velocity of the falling weight will be equal to 115% of the rated car speed for which the buffer is designed:

(a) three drop tests with a total test weight equal to the manufacturer's rated maximum load for which the porting is designed [see 8.3.2.2(a)]

(b) one drop test with a total test weight equal to the manufacturer's rated minimum load for which the porting is designed [see 2.7.2.2]

Following each drop test, the buffer shall be held its fully compressed position for a period of 5 min, and shall then be allowed to return free to its fully extended position and stand for 30 min to permit return of the oil to the reservoir and to permit escape of any air entrained in the oil.

On each of these tests, the average retardation of the test weight, during the stroke of the buffer, shall not exceed 9.81 m/s2 (32.2 ft/s2), and any retardation peak having a duration of more than 0.04 s shall not exceed 24.5 m/s2 (80.5 ft/s2).

On completion of the drop tests, no part of the buffer shall show any permanent deformation or injury.

(a) Two drop tests shall be made as follows:

(1) One drop test shall be made with the porting as specified in 8.3.2.2(a), with a total test weight equal to 120% of the manufacturer's rated maximum load, from a height such that the maximum velocity attained by the falling weight during the buffer compression shall be equal to 125% of the rated car speed for which the buffer is rated. In this test, the retardation shall be noted and shall be permitted to exceed the values specified in 8.3.2.5.1.

Immediately following this test, the buffer shall be examined externally for visible deformation or injury. If no damage is apparent, the buffer shall then be fully compressed at low speed and then released to determine if it will return freely to its extended position.

(2) After the buffer has been examined externally and has returned freely to its extended position, a second drop test shall be made from the same height and with the same load as specified in 8.3.2.5.1(a). During this test, the retardation shall not exceed the corresponding retardation developed in the test specified in 8.3.2.5.1(a) by more than 5%.

(b) If for given stroke of buffer having more than one porting, the construction of the buffer varies for the different portings, then a strength test similar to that specified in 8.3.2.5.2(a)(1) shall also be made for the porting having the range at minimum loads for which the porting is designed as specified in 8.3.2.2(b).

Following each drop test, the buffer shall be held in its fully compressed position for a period of 5 min, and shall then be allowed to freely return to its fully extended position and stand for 30 min to permit return of the oil to the reservoir and to permit the escape of any air entrained in the oil.

Tests for oil leakage shall be made concurrently with the retardation tests specified in 8.3.2.5.1, and the drop test specified in 8.3.2.5.2(a)(2), to determine the loss of oil during these tests. The oil level shall be noted after the buffer has returned to its fully extended position following each drop test, and after the time interval specified in 8.3.2.5.1.

The drop in oil level, as indicated by these measurements, shall show no loss of oil exceeding 5 mm/m (0.06 in./ft) of buffer stroke, but in no case shall the loss be such as to lower the oil level below the bottom of the plunger or below the highest metering orifice, whichever is higher.

Where the volume of oil above the porting is small when the buffer is filled to its normal working level, the laboratory shall be permitted to make additional tests for oil leakage.

During the drop tests specified in 8.3.2.5.1 and 8.3.2.5.2, the time required for the buffer plunger to return to its fully extended position, measured from the instant the test weight is raised clear of the buffer until the plunger has returned to its fully extended position, shall be noted. This time shall be not more than 90 s.

Should the plunger fail to return to its fully extended position, or should the time required for it to return to its fully extended position exceed the time specified, the manufacturer shall either submit a duplicate buffer or install a new pressure cylinder and piston, following which the plunger-return test shall be repeated. Should the buffer again fail to meet the plunger-return test requirements, it shall be rejected.

Buffers of the spring-return type shall be tested for plunger return with a 20 kg (45 lb) test weight resting on top of the plunger during the test. The plunger shall be depressed 50 mm (2 in.) and when released, the plunger, while supporting the test weight, shall return to its fully extended position within 30 s.

The following tests shall be made for lateral movement.

(a) Spring-Return-Type Buffers. The lateral movement at the top of the fully extended plunger shall be accurately measured, the upper end of the plunger being manually moved from its extreme right to its extreme left position. One-half of the total movement measured shall be considered as being the true lateral movement at the top of the plunger and shall not exceed 5 mm/m (0.06 in./ft) of buffer stroke.

(b) Gravity-Return-Type Buffers. A similar test for lateral movement shall be made. The measurement shall be taken at the lower end of the buffer cylinder when the buffer plunger is fully extended and braced to prevent lateral movement. One-half of the total movement measured shall not exceed 5 mm/m (0.06 in./ft) of buffer stroke.

After the buffer has been subjected to all of the specified tests, and all test records and data indicate that it conforms to Section 2.22, and to the requirements of 8.3.2, the laboratory shall issue a test report and a certificate to the manufacturer.
The certificate shall conform to 8.3.1.3.1 and shall include the following:

For elongations greater than or equal to 10%, the valve shall be subjected to a hydraulic pressure 7.5 times the component rated pressure. For elongations of less than 10%, the test valve shall be 2.25 times the value indicated by 8.2.8.5 multiplied by the component rated pressure. The strength test for this hydraulic pressure shall be maintained for a period of 5 min. During the test, the valve body shall not rupture.

NOTES:

  1. In order to obtain and maintain the test pressure, it is permissible to substitute alternate sealing material and tighten bolts during the test.
  2. It is not expected that the valve will be able to perform its function during or after the valve body strength test.
This Section specifies the engineering tests of safety nuts and speed-limiting devices that are permitted as alternate safety devices on screw-column elevators driven by alternating current squirrel cage motors and having a down speed of not more than 0.38 m/s (75 ft/min).
The test shall be made in either the manufacturer's plant, in a testing laboratory, or in the field by suspending the elevator car with rated load a distance above the safety nut of at least 13 mm (0.5 in.) and allowing it to drop (free-fall) until the entire load rests on the safety nut. The test shall be witnessed by, and the test results certified by, a testing laboratory or registered professional engineer. After the test, the screw column, screw supports, safety nut, guide rails, and car frame shall be inspected to determine that there has been no damage. A test on a given capacity elevator shall be accepted for all similarly designed elevators by that manufacturer for the same or lesser capacity (rated load).
The test shall be made either in the manufacturer's plant, in a testing laboratory, or in the field by suspending the elevator car with rated load a distance of at least 4 572 mm (15 ft) above the lower limit of normal travel and allowing it to drop (free-fall) until the descent is controlled by the speed-limiting device. The elevator car shall be allowed to continue its descent until brought to rest by the car buffer or bumper. The test shall be instrumented so that a graph of velocity versus distance can be plotted. The test shall be witnessed by, and the test results certified by, a testing laboratory or a registered professional engineer. After the test, the screw column, screw-column supports, speed-limiting device, guide rails, car buffer or bumper, and car frame shall be inspected to determine that there has been no damage. A test on a given capacity elevator shall be accepted for all similarly designed elevators by that manufacturer for the same or lesser capacity (rated load).

Step fatigue tests required in 6.1.3.5.7 and pallet fatigue tests required by 6.2.3.5.4 shall be performed as indicated in 8.3.11.1 through 8.3.11.6.

The test shall be made at either the manufacturer's facility or at a testing laboratory.
Escalator steps shall be mounted in an arrangement that duplicates the conditions on the escalator incline and their attachment to the step chain. Moving walk pallets shall be mounted in an arrangement that duplicates the condition of a horizontal moving walk and their attachment to the pallet chain.
The steps or pallets shall be subjected to a load varying from 450 N (100 lbf) to 3 000 N (650 lbf) at a frequency of 10 Hz ± 5 Hz for 5 000 000 cycles. An undisturbed harmonic force flow shall be achieved.
The load shall be applied normal to the tread surface to a plate 25 mm (1 in.) thick, 200 mm (8 in.) wide, and 300 mm (12 in.) long, located at the center of the step or pallet, with the 300 mm (12 in.) dimension in the direction of step or pallet travel.
The step or pallet shall have no fractures or permanent tread surface deflection exceeding 4 mm (0.16 in.) following the completion of the test. The deflection of 4 mm (0.16 in.) does not include any set or wear in the supporting wheels.
This test is to be performed on each step or pallet width.

Suspension-member tests required in 2.20.11 shall be performed as required by 8.3.12.1 through 8.3.12.3. Test results shall be documented as required by 8.3.12.4.

A test shall be required on each combination of suspension member, driving sheave design, and materials of construction. The test shall be conducted with the contact-surface geometry of the test specimens that results in the highest surface-pressure condition between the suspension member and driving sheave. A test on a given suspension member at its maximum allowable load shall be accepted for all similarly designed combinations by that manufacturer for any lesser load carried per suspension member. The suspension members and driving sheave combination shall be tested under the conditions for which they were designed.
One or more suspension member(s), loaded in tension to the maximum capacity to be qualified, shall be applied to its (their) driving sheave. The suspension member(s) shall be prevented from moving. The driving sheave shall be rotated at a speed no less than that corresponding to the maximum inspection speed of the elevator to which the suspension means is to be applied.
As a result of the test required by 8.3.12.2, no suspension member shall part before a minimum of 4 min.

One or more suspension member(s), loaded in tension to the maximum capacity to be qualified, shall be applied to its (their) driving sheave. The suspension member(s) shall be run at a speed corresponding to the maximum speed for which the suspension means is to be applied with respect to its (their) drive sheave. The drive sheave shall be subjected to three successive emergency stops, each causing the suspension members to slip traction over the driving sheave [see 8.3.12.4(g)]. The tests shall be so arranged that slippage occurs over substantially the same portion of the suspension means during successive tests. The duration of the slip shall correspond to that attained by the elevator counterweight and car with rated load initially moving at rated speed, and decelerating, on their own, to a complete stop. It shall be permitted to conduct this test on an installed elevator or in a suitable testing facility.

As a result of the test required by 8.3.12.3, suspension member(s) shall not sustain damage that would require replacement according to the criteria of ASME A17.6, Sections 1.10, 2.9, and 3.7, as applicable.
For the tests required in 8.3.12.2 and 8.3.12.3, the testing facilities, test procedure, and test results shall be documented in engineering reports. The following information shall be provided in each engineering report:

(a) date(s) of the test

(b) name and address of location where tests were conducted

(c) name, position, and organization of the person(s) conducting, supervising, or witnessing the tests

(d) description of apparatus and equipment used to perform the tests

(e) description of instrumentation used to measure or record data

(f) definition and description of the suspension member(s) and the driving sheave to which it (they) is (are) being applied, including part number, type designation, or other identification

(g) the values of the loads and speeds for which the suspension members and their sheaves are to be qualified

(h) the sheave rotation speed for Test 8.3.12.2

(i) description of the test procedure and pass/fail criteria

(j) observations noted during the test

(k) test results and test data

(l) conclusions indicating compliance with the acceptance criteria

The application required in 8.3.1.2 shall include information on the expected maximum impact speed and maximum and minimum total loads.
The drawings required in 8.3.1.2.2(b) shall show

(a) the exact construction of the buffer

(b) all dimensions of each part

(c) all pertinent information concerning materials, clearances, and tolerances

(d) the data as marked on the buffer marking plate required by 2.22.5.5

Tests shall be made on a buffer of each type or design to be installed. Each buffer shall conform to the documents submitted. The buffer test shall be on a production model or a buffer identical to the model to be produced. Modifications or special adjustments for the purpose of meeting the test requirements are prohibited.
The testing equipment shall be of such design as to perform the tests specified herein and to determine that the buffer conforms to all the requirements of Section 2.22 for elastomeric buffers and also to 8.3.13.3.1 through 8.3.13.3.3.
The required drop-test load shall be accurate to within ±1%. See 8.3.1.5.
The test weight shall be so guided as to ensure that when dropped onto the buffer, its travel shall be substantially vertical. See also 8.3.13.5.2.
The instruments used to measure the test results shall conform to the following requirements:

(a) The instruments shall be of the recording type and be capable of detecting signals at intervals of 0.01 s.

(b) The measuring chain, including the recording device for the recording of measured values as a function of time, shall be designed with a system frequency of at least 1,000 Hz.

(c) The instruments shall provide data for the plotting of the buffer performance curves showing time intervals, travel of test weight, velocity of test weight, and retardation of test weight during the buffer stroke, and the data shall be accurate to within the following tolerances:

(1) Time increments and total time shall be recorded with an error of less than ±0.5%.

(2) The position of the test weight at each time interval shall be recorded with an error of less than ±0.1%.

(3) Time, travel, velocity, and retardation shall be determined by means of a device that provides the accuracy specified.

An elastomeric buffer shall be placed on a foundation designed to withstand without appreciable deformation the forces resulting from the buffer compression on the drop tests. The buffer shall be installed in a vertical position and located centrally in relation to the drop-test weight.
The buffer shall be installed on the foundation in the same manner as in normal service, or by equivalent means, in accordance with the manufacturer's drawings.
The buffer shall be tested as follows:

Test weights shall be dropped and allowed to fall freely from a height that ensures the test weights will have reached the required maximum speed by the moment of impact. The falling distance, speed, acceleration, and retardation of each test weight shall be recorded from the moment of release to the moment of complete standstill.

The test weights shall correspond to the maximum and minimum loads called for. They shall be guided vertically with the minimum friction possible, so that at the moment of impact at least 0.9 × gravity is reached.
The ambient temperature shall be between 15°C (59°F) and 25°C (77°F).
Three tests shall be made with the maximum load called for, and three tests with the minimum load called for.

The time delay between two consecutive tests shall be not less than 5 min and not more than 30 min. In each of the three tests with maximum load, the value of reference of the buffer force at a stroke equal to 50% of the real height of the buffer given by the applicant shall not vary by more than 5%. For the tests with minimum load, the same procedure shall be followed.

The retardation shall conform to the following requirements:

(a) The average retardation in case of free fall with rated load in the car from a speed equal to 115% of the rated speed shall not exceed 1 × gravity. The average retardation shall be evaluated taking into account the time between the first two absolute minima of the retardation.

(b) Peaks of retardation with more than 2.5 × gravity shall not be longer than 0.04 s.

After the tests with the maximum mass, no part of the buffer shall show any permanent deformation or be so damaged as to prevent the required operation of the buffer.
After the buffer has been subjected to all of the specified tests, and all test records and data indicate that it conforms to Section 2.22 and 8.3.13, the laboratory shall issue a test report and a certificate to the manufacturer.
The certificate shall conform to 8.3.1.3.1 and include the following:

(a) the maximum impact speed

(b) the maximum total load

(c) the minimum total load

(d) a statement to the effect that the buffer tested has met the requirements of Section 2.22 and 8.3.13 for the maximum and minimum loads as stated in the certificate

(e) a list of any environmental and life-cycle conditions (where applicable) for use of buffers with nonlinear characteristics (see 2.22.1.1.5)

When buffers fail to perform satisfactorily in tests using the minimum and maximum loads indicated on the application, the laboratory may, in agreement with the applicant, establish the acceptable limits.
