ISO 19685:2017 identifies parameters of Pirani gauges, their calibration procedure, and describes measurement uncertainties to be considered when operating these gauges. ISO 19685:2017 applies to Pirani vacuum gauges operating over a pressure range of 0,01 Pa to 150 kPa. ISO 19685:2017 complements ISO 3567 and ISO 27893 when calibrating Pirani gauges and using them as reference standards. In…

IEC 61400-25-5:2017 specifies standard techniques for testing of compliance of implementations, as well as specific measurement techniques to be applied when declaring performance parameters. The use of these techniques will enhance the ability of users to purchase systems that integrate easily, operate correctly, and support the applications as intended. This part of IEC 61400-25 defines: the…

IEC 60404-8-8:2017(E) defines the grades of thin non-oriented electrical steel strip and sheet in nominal thicknesses of 0,05 mm, 0,10 mm, 0,15 mm, 0,20 mm, 0,25 mm, 0,30 mm and 0,35 mm and of thin grain-oriented electrical steel strip and sheet in nominal thicknesses of 0,05 mm, 0,10 mm, 0,15 mm and 0,18 mm. In particular, it gives general requirements, magnetic properties, geometric…

IEC 62688:2017 describes the fundamental construction and testing requirements for Concentrator Photovoltaic (CPV) modules and assemblies in order to provide safe electrical and mechanical operation during their expected lifetime. Specific topics are provided to assess the prevention of electrical shock, fire hazards, and personal injury due to mechanical and environmental stresses. This document…

ISO 10075-1:2017 defines terms in the field of mental workload, covering mental stress and mental strain, and short- and long-term, positive and negative consequences of mental strain. It also specifies the relations between these concepts involved. In this document, mental workload is regarded as an umbrella or generic term, referring to all the concepts and constructs mentioned in the document…

ISO 16128-2:2017 describes approaches to calculate natural, natural origin, organic and organic origin indexes that apply to the ingredient categories defined in ISO 16128‑1. This document also offers a framework to determine the natural, natural origin, organic and organic origin content of products based on the ingredient characterization. Neither ISO 16128‑1 nor this document addresses product…

IEC 60404-8-7:2017 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. IEC 60404-8-7:2017 defines the grades of cold-rolled grain-oriented electrical steel strip and sheet in nominal…

IEC 62822-3:2017 applies to equipment for resistance welding and allied processes designed for occupational use by professionals and for use by laymen. This document specifies procedures for the assessment of human exposure to magnetic fields produced by resistance welding equipment. It covers non-thermal biological effects in the frequency range from 0 Hz to 10 MHz and defines standardized test…
