    Definition
  • Provides guidance for the assessment of surface spread of flame for electrotechnical products and the materials from which they are formed. It provides an explanation of the principles of flame spread for both liquids and solids, guidance for the selection of test methods, guidance on the use(...)
  • Presents a summary of published test methods that are used to determine the surface spread of flame of electrotechnical products or materials from which they are formed. It represents the current state of the art of the test methods and, where available, includes special observations on their(...)
  • Specifies the ball pressure test as a method for evaluating the softening temperature and accelerated material flow under load of polymeric materials and parts of end products in their ability to resist abnormal heat. It is applicable to the materials used in electrotechnical equipment,(...)
  • Gives the requirements for the production and confirmation of a nominal 1 kW, propane/air pre-mixed test flame. This basic safety publication is intended for use by technical committees in the preparation of standards in accordance with the principles laid down in IEC Guide 104 and ISO/IEC Guide 51.
  • Provides detailed requirements for the production of either of two 500 W nominal, pre-mixed type test flames. The approximate overall height of each flame is 125 mm.
  • Provides a description of the apparatus required to produce a 50 W test flame and a description of a calibration procedure to check that the test flame produced meets given requirements.
  • Specifies a needle-flame test to simulate the effect of a small flame which may result from fault conditions, in order to assess by a simulation technique the fire hazard. It is applicable to electrotechnical equipment, its sub-assemblies and components and to solid electrical insulating(...)
  • Specifies small-scale laboratory test procedures intended to compare the burning behaviour of different materials used in electrotechnical products when vertically or horizontally oriented test bar specimens are exposed to a small flame ignition source with a nominal thermal power of 50 W.
  • Specifies a small-scale laboratory screening procedure for comparing the relative burning behaviour of specimens made from plastics and other non-metallic materials, as well as their resistance to burn-through when exposed to a flame ignition source of 500 W nominal power.
  • Applies to electric appliances (including their accessories or components) for household and similar use, supplied from mains or from batteries
  • Defines the technical requirements to be met for I&C systems important to safety and their cables, in order to achieve adequate physical separation between redundant sections of a system and between a system and another system.
  • Presents a set of software subroutines to provide a general capability for communications with CAMAC systems as defined in IEC 60516
  • Applies to the partial evaluation of thermal motor protectors as defined in IEC 60730-1 for household and similar use, including heating, air conditioning and similar applications as well as for sealed (hermetic and semi-hermetic type) motor-compressors. A thermal motor protector is considered(...)
  • IEC 60737:2010 deals with specific requirements for nuclear applications of temperature sensors. It provides guidance which will help to ensure that the reactor conditions do not damage the temperature sensors; it ensures that the in-core temperature measuring system and the sensor(...)
  • Specifies the apparatus and procedure for the determination of the amount of halogen acid gas, other than hydrofluoric acid, evolved during the combustion of compounds based on halogenated polymers and compounds containing halogenated additives taken from electric or optical fibre cable(...)
  • Specifies the apparatus and procedure for the determination of the potential corrosivity of gases evolved during the combustion of materials taken from electric or optical fibre cable constructions by measuring the acidity (pH) and conductivity of an aqueous solution resulting from the gases(...)
  • Lays down mandatory general requirements and gives examples of acceptable methods for equipment for continuous monitoring of radioactivity in gaseous effluents. Specifies general characteristics, general test procedures, radiation, electrical, safety and environmental characteristics and the(...)
  • Establishes specific standard requirements, including technical characteristics and general test conditions, and gives examples of acceptable methods for aerosol effluent monitors.
  • Lays down specific standard requirements, including technical characteristics and general test conditions, and gives examples of acceptable methods for noble gas effluent monitors.
  • Lays down specific standard requirements, including technical characteristics and general test conditions, and gives examples of acceptable methods for iodine monitors.
