Optics and photonics. Optical materials and components. Test method for homogeneity of infrared optical materials1 Scope This document specifies the principle, apparatus, condition, sample, procedure and data processing of measuring homogeneity of infrared optical materials. It is applicable to the determination of homogeneity of infrared optical materials, such as infrared optical glass, infrared crystals and infrared ceramics, which are opaque to visible wavelengths and whose transmission optical spectra are beyond 0,78 m.

BS EN 4056-004 is the fourth part of a multi-part series that defines the characteristics of cable ties with either internal or external serrations manufactured entirely from plastics material
