This Standard sets out the method for determining the percentage of weak particles in coarse aggregates.

Sets out general design and performance requirements and testing procedures for mechanical locksets and latchsets in residential and commercial buildings. Also includes performance requirements for cylinders supplied separately for installation in locksets.

Specifies requirements and tests for hot-dip zinc coatings on fabrications, assembled steel products, tubular fabrications, fabricated wire work, steel forgings, steel stampings, ferrous castings, nails and small components.

Specifies a spectrophotometric method for the determination of the phosphorus content of iron and steel. The method is applicable to the determination of phosphorus contents between 0.005 percent and 2.0 percent, provided that the following elements are not present in amounts greater than that specified: niobium 1 percent, tantalum 1 percent, titanium 2 percent, tungsten 11 percent, zirconium 1 percent.

This Standard sets out the method for determining the friction value of a surface using the pendulum friction tester on test specimens prepared from naturally occurring or artificially produced materials which are intended for use as roadway pavement surfacing material.

Specifies requirements for the production and supply of welded I sections for general structural and engineering purposes.

Specifies the requirements for the production and supply of cold-formed, electric resistance-welded, steel hollow sections used for structural purposes. It considers three strength grades, with or without impact properties, that are suitable for welding.

This Standard specifies requirements for the design, construction, performance and testing of emergency luminaires and exit signs. It applies both to emergency luminaires and exit signs that are centrally supplied, and to emergency luminaires and exit signs of the selfcontained type.

Specifies performance requirements for prepainted and organic film/metal laminate products in sheet and strip form that are coated on one or both sides with an organic film, and that are intended for fabrication into products for use in the construction or finishing of buildings.

This Standard specifies a method for the determination of the thickness of pile above the substrate of a textile floor covering. It is applicable to all textile floor coverings with pile capable of being shorn from the substrate, but not to textile floor coverings of varying pile thickness or density, unless the areas can be measured separately.
