This document specifies requirements and test methods for assessing the resistance to cutting of gaiters by hand-held chainsaws and other properties. It includes a requirement and a test method for assessing the strength of underfoot straps of gaiters. This document is applicable to gaiters used in conjunction with safety footwear with a steel toecap conforming to ISO 20345 design "C"…

This document provides concepts, specification and qualification of 2G HTS joining procedure. A welding procedure specification (WPS) is needed to provide a basis for planning joining operations and for quality control during joining. Joining is considered as a special process in the terminology of standards for quality systems. Standards for quality systems usually require that special processes…

IEC 62899-203:2018(E) defines terms and specifies standard methods for characterisation and evaluation. This document is applicable to semiconductor inks and semiconductive layers that are made from semiconductor inks.

This document defines key establishment mechanisms using symmetric cryptographic techniques. This document addresses three environments for the establishment of keys: Point-to-Point, Key Distribution Centre (KDC), and Key Translation Centre (KTC). It describes the required content of messages which carry keying material or are necessary to set up the conditions under which the keying material can…
