22.214.171.124 Rope Socket Embedment Medium
(a) Physical Properties. The thermoset resin composition shall have the following properties:
(1) Uncured (Liquid) Material
(-a) Viscosity of Resin-Catalyst Mixture. The viscosity of the resin-catalyst mixture shall be sufficiently low to permit rapid, complete saturation of the rope rosette in order to prevent entrapment of air.
(-b) Flash Point. All components shall have a minimum flash point of 27°C (80°F).
(-c) Shelf Life. All components shall have a minimum shelf life of 1 yr at 21°C (70°F).
(-d) Pot Life and Cure Time. After mixing, the resin-catalyst mixture shall be pourable for a minimum of 8 min at 21°C (70°F) and shall cure within 1 h after hardening. Heating of the resin mixture in the socket to accelerate curing shall follow the resin manufacturer's instructions.
(2) Cured Resin
(-a) Socket Performance. Resin, when cured, shall develop sufficient holding strength to solvent-washed wire in wire rope sockets to develop 80% of the ultimate strength of all types of elevator wire rope. No slippage of wire is permissible when testing resin-filled rope socket assemblies in tension; however, after testing, some seating of the resin cone shall be permitted to be apparent and is acceptable. Resin terminations shall also be capable of withstanding tensile shock loading.
(-b) Shrinkage. The volumetric shrinkage of fully cured resin shall not exceed 2%. The use of an inert filler in the resin is permissible.
(-c) Curing. The resin-catalyst mixture shall be capable of curing either at ambient [16°C to 38°C (60°F to 100°F)] or elevated temperatures. At temperatures below 16°C (60°F), an elevated-temperature cure shall be used.
(b) Materials Required. The thermoset resin composition intended for elevator wire rope socketing shall be supplied in two parts consisting of preweighed resin and preweighed catalyst, each packaged separately within a kit. Each kit containing the thermoset resin composition shall consist of the following:
(1) preweighed thermoset resin
(2) preweighed catalyst
(3) necessary materials for mixing and pouring
(4) detachable label on resin container
(c) Marking of the Resin Container. The label on the resin container shall show the following information:
(1) product name
(2) part designation (e.g., "Part A" or "Resin")
(3) manufacturer's name or trademark and address
(4) mixing instructions
(5) ICC information
(6) safety warnings and cautions
(7) packaging date
(8) flash point
(9) shelf life
(10) storage instructions
(11) curing instructions
(12) net weight
(13) a statement certifying that the product conforms to 126.96.36.199.2 of ASME A17.1/CSA B44
(a) product name
(b) part designation (e.g., "Part B," "Catalyst," or "Hardener")
(c) manufacturer's name or trademark and address
(d) safety warnings and cautions
(e) flash point
(f) storage instructions
(g) net weight
