Brown coals are classified in this International Standard according to the following properties: total moisture content calculated on the ash-free basis; tar hiels calculated on the dry, ash-free basis. In tables class numbers, group number and code numbers of brown coal types are given.

States and defines test methods of interest to the users for measuring the principal performance characteristics of household electric washing machines. This standard is concerned neither with safety nor with performance requirements. This standard is applicable to horizontal drum type electric clothes washing machines, to spin extractors and to washing and spinning machines for household use. It…

Applies to string insulator units of the can and pin type and also of the long rod type as well as to the fittings used with such insulators. Defines dimensions of a series of clevis and tongue couplings to permit the assembly of insulators or fittings supplied by different manufacturers. Note: - For co-ordination between standardized dimensions and strength classes of cap and pin type…

Applicable more particularly to instrumentation for gas-cooled graphite-moderated reactors, Type 1: reactors having metallic natural uranium fuel clad with magnesium alloy, and Type 2: reactors having enriched uranium oxide fuel clad with stainless steel. The IEC 60231 series of standards is no longer up-to-date and will not be revised by IEC. The standards are maintained for the time being for…

Empirial test procedure for assessing the resistance of a single coating or for a multicoat system to cracking and/or detachment from a metal substrate when subjected to bending round a cylindrical mandrel under standard conditions. The method of test specified may be carried out either with a single specified size of mandrel or by repeating the procedure using successively smaller mandrels. Two…

Specifies the standard method to be used in comparing the contrast ratios given by paint films of white or ligth colours, of refelctance factor greater than 40 %, dried at normal air temperature and applied at approximately equal wet film thickness to black and white substrates. The wet film thickness selected, approximately 50 um, corresponds to a spreading rate of approximately 20 m2/l. Because…

1.1 These requirements cover heat actuated mechanically operated single- and multiple-station fire alarm devices intended for indoor installation in accordance with the Standard for Household Fire Warning Systems, NFPA No. 74. 1.2 The requirements do not cover electrically operated single- or multiple-station fire alarm devices actuated by heat, smoke, or combustion products.

1. SCOPE 1.1 This Standard applies to single conductor cables intended for installation in accordance with the Rules of the Canadian Electrical Code, Part I, as follows: (a) Type GTO cables for use with gas-tube systems for signs, outline lighting, and interior lighting, and for use also in the ignition systems of oil- and gas-burning equipment; and…

This is a text searchable PDF. 1.1 Scope 1.1.1 These requirements apply to natural and propane gas-fired conversion burners designed and constructed primarily for the purpose of converting heating and process equipment from the use of other fuels to gas firing and/or firing new heating or process equipment. 1.1.2 Section 2, Part A of these requirements apply to conversion…

This International Standard specifies the rest procedures suitable for establishing the compliance of wires with the performance requirements stated in ISO 2032. They are intended for use as a basis for specifying tests in the relevant national specifications when the national type approving authorities consider that existing tests are inadequate. The test procedures are classified in type tests…
