Standard Test Method for Evaluating the Freeze-Thaw Durability of Dry-Cast Segmental Retaining Wall Units and Related Concrete Units shop-only WARNING Male and female dust

WARNING Male and female dust couplings are pressure resistant plugs

describes a method for the determination of the aggregate crushing value (ACV) which gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load

It creates a standardized approach for manufacturers to adhere to if they supply their metallic materials to the aerospace and defence industry
