This document applies to - the inherent safety of automatic electrical air flow, water flow and water level sensing controls, and - functional safety of automatic air flow, water flow and water level sensing electrical controls and safety related systems, - controls where the performance (for example the effect of EMC phenomena) of the product can impair the overall safety and performance of the controlled system, - the operating values, operating times, and operating sequences where such are associated with equipment safety. This document specifies the requirements for construction, operation and testing of automatic electrical air flow, water flow and water level sensing controls used in, on, or in association with an equipment. This document takes into account the response value of an automatic action of a control where such a response value is dependent upon the method of mounting the control. Where a response value is of significant purpose for the protection of the user, or surroundings, the value defined in the appropriate h

IEC 60794-1-136:2026 specifies procedures to determine the maximum allowable push force applied on cables during the installation by blowing. Currently this parameter is determined by a separate test on the cable before installation. The methods specified in this document apply primarily to low-diameter cables (microduct cables according to IEC 60794-5) without rigid strength elements (e.g. GRP rods).

IEC 60695-2-10:2026 specifies the glow-wire apparatus and common test procedure to simulate the effects of thermal stresses which may be produced by heat sources such as glowing elements or overloaded resistors, for short periods, in order to assess the fire hazard by a simulation technique. The test procedure described in this document is a common test procedure intended for the small-scale tests in which a standardized electrically heated wire is used as a source of ignition. It is a common part of the test procedures applied to end products and to solid electrical insulating materials or other solid combustible materials. A detailed description of each particular test procedure is given in IEC 60695-2-11, IEC 60695-2-12 and IEC 60695-2-13. This fourth edition cancels and replaces the third edition published in 2021. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) revision of 4.3 to add reference to new Annex D; b) addition of new normative Annex D on "Use of pyrometer for glow-wire test"; c) revision of Clause 3 references to align with ISO 13943:2017. It has the status of a basic safety publication in accordance with IEC Guide 104. This International Standard is to be used in conjunction with IEC 60695-2-11, IEC 60695-2-12, and IEC 60695-2-13.
