This document specifies a method for the determination of the flammability of aerospace materials by upward flame propagation. This test determines if a material, when exposed to a standard ignition source, will self-extinguish and not transfer burning debris which can ignite adjacent materials.

This document specifies two test methods for determining the flammability of electrical-wire insulation and accessory materials by exposure to an external ignition source in a static environment (test A) and in a gas-flow environment (test B). These tests determine if a wire insulation material, when exposed to a standard ignition source, will self-extinguish and not transfer burning debris which…

IEC 61753-021-06:2023 defines the minimum initial test and measurement requirements and severities which single-mode fibre optic connectors terminated as a pigtail or a patchcord satisfy in order to be categorised as meeting the IEC standard category OP+ (extended outdoor protected environment), as defined in IEC 61753-1. If tests were performed on the connectors terminated as pigtails or…

IEC 61753-021-02:2023 defines the minimum initial test and measurement requirements and severities which single-mode fibre optic connectors terminated as a pigtail or a patchcord satisfy in order to be categorized as meeting the IEC standard category C (controlled environment), as defined in IEC 61753-1. If tests were performed on the connectors terminated as pigtails or patchcords for categories…

This document specifies safety requirements for auto-guidance systems used in agricultural tractors and self-propelled agricultural machines. It is applicable to auto-guidance systems which are factory installed as an integral part of the tractor or self-propelled machine, as well as systems designed to be retrofitted to equipment after such equipment has left the control of the manufacturer. It…
