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…

Applicable to all types of solid organic and inorganic cylindrical scintillators used in scintillation counting and spectrometry. Standard dimensions are given in order to facilitate interchangeability of unencapsulated scintillators and to facilitate intercomparisons of measurements made with encapsulated scintillators.

Prescribes specified values for the electrical and mechanical characteristics and for the principal dimensions of string insulator units of the long rod type with insulating parts of ceramic material intended for a.c. overhead lines with a nominal voltage greater than 1 000 V and a frequency not greater than 100 Hz. The smallest insulator unit standardized has a lighting impulse withstand voltage…

1. Scope 1.1 This Standard applies to household electric toys operating at nominal potentials of 120 volts or less, including extra low potential, and intended for use in ordinary (ie, non-hazardous) locations as defined in the Canadian Electrical Code Part I. 1.2 This Standard does not apply to battery operated toys: (a) having a battery of a non-rechargeable (primary) type; and…
