In the interests of clarity and immediate usability more details are given for procedures using instruments with Bragg-Brentano geometry and application to phase identification

BS EN 17176‑2 is part two of the BS EN 17176 series specifies the characteristics of solid-wall pipes made of oriented unplasticized Poly (vinyl chloride) (PVC-O) for piping systems intended for water supply and buried drainage

Wear resistance can be defined as the ability of a surface to resist being worn away by rubbing or friction

Electronic paper displays - Legibility of EPD in spatial frequency Ingestion-build-260237 - the optical characteristics and1 Scope This part of IEC 62679, which is a technical report, specifies the legibility in terms of contrast, spatial frequency, and reflection of the screen as a function of the physical parameters of an EPD. This legibility evaluation model is introduced through both subjective and objective assessments. The scope of this document is restricted to EPDs using segment, passive, and active matrixes with monochromatic type displays.
