This document specifies the mating dimensions for thermoplastic flange adapters and corresponding loose backing flanges intended to be used in thermoplastic piping systems for the conveyance of fluids under pressure. It applies to flange adapters and loose backing flanges for use with pipes with nominal outside diameters (dn) from 16 mm to 2 500 mm and nominal pressures up to 25 bar[1] (PN 25).…

This document specifies tests to perform in order to determine the galling tendency, sealing performance and structural integrity of casing and tubing connections. "Casing" and "tubing" apply to the service application and not to the diameter of the pipe. This document covers the testing of connections for the most commonly encountered well conditions. Not all possible service…

IEC 60947-2:2016+A1:2019 applies to circuit-breakers, the main contacts of which are intended to be connected to circuits, the rated voltage of which does not exceed 1 000 V a.c. or 1 500 V d.c.; it also contains additional requirements for integrally fused circuit-breakers. This fifth edition cancels and replaces the fourth edition published in 2006, Amendment 1:2009 and Amendment 2:2013. This…

1 Scope This part of IEC 61000 defines the immunity test methods and range of preferred test levels for electrical and electronic equipment connected to low-voltage power supply networks for voltage dips, short interruptions, and voltage variations. This standard applies to electrical and electronic equipment having a rated input current not exceeding 16 A per phase, for connection to 50 Hz…

1 Scope 1.1 This Standard describes the requirements for the design and installation of a fire alarm system with or without voice communication capability. NOTE 1: This Standard is intended to apply to both required and voluntary fire alarm installations. NOTE 2: The requirements in this Standard address the installation for various types of fire alarm system equipment and devices. These…

This document describes the management of source addresses (SAs) for control functions (CFs) of electronic control units (ECUs), the association of addresses with the functional identification of a device and the detection and reporting of network-related errors. It also specifies procedures for initialization of network-connected ECUs.

ISO/IEC 14543-5-101:2019 (E) enables a media connection, resource sharing and co-operation among computers, home appliances and consumer electronics using remote access (RA). Also, users and devices can share and control media resources. This document specifies: • an IGRS remote media access profile based on the IGRS RA core protocol and the IGRS RA platform protocol, and •…

IEC 61158-6-2:2019 provides common elements for basic time-critical and non-time-critical messaging communications between application programs in an automation environment and material specific to Type 2 fieldbus. The term “time-critical” is used to represent the presence of a time-window, within which one or more specified actions are required to be completed with some defined level of…
