IEC 62053-21:2020 applies only to static watt-hour meters of accuracy classes 0,5, 1 and 2 for the measurement of alternating current electrical active energy in 50 Hz or 60 Hz networks and it applies to their type tests only. This document applies to electricity metering equipment designed to: • measure and control electrical energy on electrical networks (mains) with voltage up to 1 000 V AC…

1 Scope This National Standard of Canada defines equipment requirements, performance criteria, and operating and testing procedures for the implementation of a vapour control system (VCS) in gasoline distribution networks including terminals, bulk plants, service stations and cargo tanks, commonly known as Stage I (see Figure 1 for a schematic representation). This standard does not include…

1 SCOPE 1.1 This method of test for surface burning characteristics of building materials is applicable to any type of building material that, by its own structural qualities or the manner in which it is applied, is capable of supporting itself in position or may be supported in the test furnace as described in this Standard (see Appendix A) or in a manner comparable to its recommended use.…

This document describes procedures to characterize quadrupole mass spectrometers (QMSs) with an ion source of electron impact ionization and which are designed for the measurement of atomic mass-to-charge ratios m/z < 300. This document is not applicable to QMSs with other ion sources, such as chemical ionization, photo-ionization or field ionization sources and for the measurements of higher…

L'IEC 60942:2017 spécifie les exigences de performance de trois classes de calibreurs acoustiques: la classe LS (Laboratory Standard, étalon de laboratoire), la classe 1 et la classe 2. Les limites d'acceptation les plus faibles concernent la classe LS et les plus élevées concernent les appareils de classe 2. Les calibreurs acoustiques de classe LS ne sont normalement utilisés qu'…
