Plastics — Homopolymer and copolymer resins of vinyl chloride — Part 1: Designation system and basis...
1.1 This document establishes a system of designation for vinyl chloride thermoplastic resins which can be used as the basis for specifications.
1.2 The types of vinyl chloride plastics are differentiated from each other by a classification system based on appropriate levels of the designatory properties:
a) reduced viscosity;
b) apparent density;
c) retention on a 63 µm mesh sieve;
d)…
Optical fibres - Part 1-34: Measurement methods and test procedures - Fibre curl
IEC 60793-1-34:2021 establishes uniform requirements for the mechanical characteristic: fibre curl or latent curvature in uncoated optical fibres, i.e. a specified length of the fibre has been stripped from coating. Fibre curl has been identified as an important parameter for minimizing the splice loss of optical fibres when using passive alignment fusion splicers or active alignment mass fusion…
