IEC 62351-5:2023 defines the application profile (A-profile) secure communication mechanism specifying messages, procedures and algorithms for securing the operation of all protocols based on or derived from IEC 60870-5, Telecontrol Equipment and Systems – Transmission Protocols. For the measures described in this document to take effect, they must be accepted and referenced by the…

IEC TS 62736:2023 specifies requirements and methods for periodic testing of the quality of diagnostic medical ultrasound systems using reflection-mode (pulse-echo) imaging. Image measurement and interpretation workstations are included. This document includes minimum sets of such tests intended for frequent users of medical ultrasound systems, for quality assurance professionals in their…

This document specifies the requirements for the performance testing of membrane filters used for the retention followed by direct enumeration of microorganisms by culture methods. This document is applicable to membrane filters which are used for retention followed by direct enumeration of specific microorganisms on solid media or on other devices containing media, like absorbent pads[19]. This…

IEC TR 61292-4:2023 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 TR 61292-4:2023 which is a Technical Report, applies to all commercially available optical amplifiers (OAs),…

IEC TR 61292-4:2023 which is a Technical Report, applies to all commercially available optical amplifiers (OAs), including optical fibre amplifiers (OFAs) using active fibres as well as Raman amplifiers. Semiconductor optical amplifiers (SOAs) using semiconductor gain media are also included. This document provides informative guidelines on the threshold of high optical power that can cause high-…

This document provides specifications and illustrations for the positioning and orientation of parts with regards with coordinate systems and testing methodologies for additive manufacturing (AM) technologies in an effort to standardize the method of representation used by AM users, producers, researchers, educators, press/media, and others, particularly when reporting results from testing of…

The current ISO 16355 series is written intentionally independent of industry because the principles of applying statistical methods for product and technology development are similar for all types of products. However, when applying the standard for the development of fully or partially digitized products in practice, specific characteristics of digital goods in product development (such as…

1 Scope 1.1 General This Standard details mechanical, physical, and electrical requirements for a newly manufactured appliance that compresses natural gas for vehicles and dispenses directly into a) the vehicle natural gas fuel storage system, referred to as a residential fuelling appliance (RFA); or b) the vehicle’s activated carbon adsorbents-based adsorbed natural gas (ANG) fuel storage…
