Machine tools. Dimensions and geometric tests for self-centring chucks with two-piece jaws - Power-operated chucks with tongue and groove type jaws shop-only This International Standard specifies two

This International Standard specifies two reference wavelengths to be used for the characterization of optical materials

the normal incidence absorption and the impedance ratios of the acoustic material

This International Standard specifies a method for examining the ignition characteristics of the exposed surfaces of specimens of essentially flat materials

BS EN 3869 is useful for entities in the aerospace industry as BS EN 3869 lists the characteristics of seals for pipe couplings in fluorocarbon rubber and armature in the aluminium alloy which helps to produce quality aerospace applications

(BS 4395-1:1969 and BS 4395-2:1969 currently support BS 449 and BS 5950)
