Historical (view previous versions of standard)
This specification covers the standard requirements for lead and lead alloy strip, sheet, and plate products intended for use in chemical plants, sound attenuation, roofing, vibration dampening, flashing and weather stripping, waterproofing, and radiation shielding. The lead sheet, strip, or plate shall be manufactured by rolling or extruding the product from a lead work piece which may be prepared by conventional casting into a mold or by direct continuous casting. Chemical analysis shall be performed on the samples which shall be taken during pouring the casting prior to working or during subsequent processing, such as rolling or cutting. The material shall conform to the product analysis variation in the chemical composition specifications for antimony, arsenic, tin, copper, silver, bismuth, zinc, tellurium, nickel, iron, and lead. Tension and hardness tests shall also be conducted on the specimens which shall be taken in the direction of rolling from the material in the final condition of rolling and heat treatment or in the case of continuously cast sheet in the casting direction and as cast state. The lead products shall be uniform in quality and hardness, smooth, commercially straight and flat, and free of injurious imperfections such as pits, dents, scratches, laminations, grit, foreign matter, porosity, or waves that may affect the serviceability of material.

1.1 This specification covers lead sheet, strip, and plate of various alloys intended for use in chemical plants, sound attenuation, roofing, vibration dampening, flashing and weather stripping, waterproofing, and radiation shielding.
1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to become familiar with all hazards including those identified in the appropriate Material Safety Data Sheet (MSDS) for this product/material as provided by the manufacturer, to establish appropriate safety and health practices, and determine the applicability of regulatory limitations prior to use.
