ISO 81346-10:2022 This document provides rules for structuring of systems in the domain of power supply systems, being supplementary to the general principles for the structuring of systems including structuring of information about systems specified in IEC 81346-1. Based on these principles, rules and guidance are given for the formulation of unambiguous reference designations for objects in…

This part of IEC 60839 defines the minimum requirements and guidance for the installation and operation of electronic access control systems (EACS) and/or accessory equipment to meet different levels of protection. This standard includes requirements for planning, installation, commissioning, maintenance and documentation for the application of EACS installed in and around buildings and areas…

This document establishes a conditioning method to determine the minimum fractional test efficiency. It is intended to be used in conjunction with ISO 16890‑1, ISO 16890‑2 and ISO 16890‑3, and provides the related test requirements for the test device and conditioning cabinet as well as the conditioning procedure to follow. The conditioning method described in this document is referring to a test…

This document describes a procedure for measuring the performance of general ventilation air cleaning devices in their end use installed configuration. The performance measurements include removal efficiency by particle size and the resistance to airflow. The test procedures include the definition and reporting of the system airflow. The procedure describes a method of counting ambient air…

This document specifies the aerosol production, the test equipment and the test methods used for measuring fractional efficiency and air flow resistance of air filters for general ventilation. It is intended to be used in conjunction with ISO 16890‑1, ISO 16890‑3 and ISO 16890‑4. The test method described in this document is applicable for air flow rates between 0,25 m3/s (900 m3/h, 530 ft3/min)…

The scope of this standard is to define one medium access control (MAC) and several physical layer (PHY) specifications for wireless connectivity for fixed, portable, and moving stations (STAs) within a local area.

IEC 61753-053-02: 2022 contains the minimum initial test and measurement requirements and severities which non-connectorized single-mode fibre electrically controlled variable optical attenuator needs to satisfy in order to be categorised as meeting the requirements of category C – Controlled environments, as defined in Annex A of IEC 61753-1:2018. This first edition cancels and replaces IEC…

The scope of this standard is to define one medium access control (MAC) and several physical layer (PHY) specifications for wireless connectivity for fixed, portable, and moving stations (STAs) within a local area.

This document defines the OTX core requirements and data model specifications. The requirements are derived from the use cases described in ISO 13209-1. They are listed in the requirements section. The data model specification aims at an exhaustive definition of all OTX core features implemented to satisfy the core requirements. Since OTX is designed for describing test sequences, which…

This document defines the gravimetric method for determining the contamination level of fluids used in hydraulic fluid power systems. The working instructions provided in this document serve for the gravimetric determination of dirt content of pressure fluids from mineral oil with additives. They are used in hydraulic systems with hydrostatic drive.
