IEC 60317-4:2015 specifies the requirements of solderable enamelled round copper winding wire of class 130 with a sole coating based on polyurethane resin, which may be modified provided it retains the chemical identity of the original resin and meets all specified wire requirements. The range of nominal conductor diameters covered by this standard is: - Grade 1: 0,018 mm up to and including 2,…

1 PURPOSE AND SCOPE This standard specifies the characteristics and test methods relating to unplasticized poly(vinyl chloride) [PVC-U] pipe having a nominal diameter ranging from 100 mm to 1500 mm. This standard applies to socket-ended pipe with gasket seals made of elastomer, with or without a restraint system integrated to the pipe, and applies to pipe without socket. These pipes are intended…

ISO 18843:2015 sets out a method for determining the amount of time taken for a given quantity of smelter-grade alumina to flow by gravity through a precisely constructed standard funnel. NOTE Variations in the apparatus and other test variables can create significant inter-laboratory differences in results. (See Table A.1.)

1.1 This Standard covers the refurbishing of shop fabricated tanks built to nationally recognized Standards listed in Tank Eligibility Subsections 6.2 and 7.2. NOTE: In the context of this Standard, refurbishing refers to repairs to, and a limited set of modifications of, tanks using materials at least equivalent to those used in the original manufacture and does not include retrofit. Refer to…

1 Scope This part of IEC 61481 is applicable to portable phase comparators of capacitive type to be used on electrical systems for voltages exceeding 1 kV a.c. and frequencies of 50 Hz and/or 60 Hz. This standard is applicable to: ?? single-pole phase comparators of capacitive type operating with a memory system up to 36 kV a.c., ?? two-pole phase comparators of capacitive type operating with a…

1 Scope This part of IEC 61481 is applicable to portable phase comparators of resistive type to be used on electrical systems for voltages from 1 kV a.c. to 36 kV a.c. and frequencies of 50 Hz and/or 60 Hz. This standard is applicable to phase comparators of resistive type used in contact with the bare conductive parts to be compared: ?? as a complete device including its insulating element or…

1 Scope This part of IEC 61243 is applicable to hand-held two-pole voltage detectors with their accessories (crocodile clips and detachable leads) to be used in contact with parts of electrical systems: – for a.c. voltages not exceeding 1 000 V at nominal frequencies between 16 2 3 Hz and up to 500 Hz, and/or – for d.c. voltages not exceeding 1 500 V. NOTE The a.c. voltages defined in…

1 Scope This International Standard is applicable to electrical insulating gloves and mitts that provide protection of the worker against electric shock. Unless otherwise stated, the use of the term “glove” includes both gloves and mitts. This standard also covers electrical insulating gloves with additional integrated mechanical protection referred to in this document as “composite gloves”. The…

1.1 There is a commentary available for this Clause. This Standard covers the design, construction, operation, maintenance, deactivation, and abandonment of oil and gas industry pipeline systems that convey a) liquid hydrocarbons, including crude oil, multiphase fluids, condensate, liquid petroleum products, natural gas liquids, and liquefied petroleum gas; b) oilfield water; c) oilfield…

1.1 This Standard applies to manually operated and mechanically operated special use switches that are a) for use on dc, ac/dc, or ac only; and b) rated at not more than i) 60 A at 250 V or less; or ii) 30 A or 2 hp at 600 V or less and intended for use in accordance with the Canadian Electrical Code, Part I. 1.2 This Standard does not apply to a) switches forming parts either of…
