Lasers and laser-related equipment. Test methods for determination of the shape of a laser beam wavefront - Terminology and fundamental aspects subscription-only1 Scope This part of ISO 15367 specifies methods for the measurement of the topography of the wavefront of a laser beam by measurement and interpretation of the spatial distribution of the phase of that wavefront across a plane approximately perpendicular to its direction of propagation. Requirements are given for the measurement and analysis of phase distribution data to provide quantitative wavefront parameters and their uncertainty in a test

BS EN ISO 4288:1998

BS EN 485-3 on tolerances for hot-rolled aluminum products is relevant to:

in which case special measures may be necessary to achieve good dispersion of the compound

you can ensure that your products are safe and reliable in operation and effective at the point of use

The steels are not suitable for hot forming
