When deemed impractical to conduct adequate tests prior to installation, the Department is authorized to grant tentative approval and permission to make installation as proposed. Final approval shall not be given until tests conducted after installation show that the material, device, fixture, method of assemblage, installation, appurtenance or appliance meets the intent of this code, functions as required, and conforms to the conditions of approval set forth by the Department.
Whenever the standard under which a material, fixture, or device is approved requires that the item be identified in a specified manner as to weight or quality, such identification shall be provided in accordance with the standard.
Solder and solder fluxes shall have labels stating: "Contains 0.02% or less lead." Pursuant to Pennsylvania Act #33, July 6, 1993, solder which does not conform to this standard shall not be offered for sale in the City, either at retail or wholesale outlets. All non-conforming solder shall be subject to confiscation by the Department.
