This extended version of the official IEC Standard is available in English only and provides the user with the comprehensive content of the Standard. IEC 60335-2-4:2023 EXV includes the content of the references made to IEC 60335-1:2020. IEC 60335-2-4:2023 deals with the safety of: - stand-alone…

This document specifies qualities for flat and long products of hot-rolled structural steels with improved atmospheric corrosion resistance in the as-rolled, normalized/normalized rolled, thermomechanical control processed and quenched and tempered delivery conditions. It is applicable to steel plates rolled on a reversing mill, wide flats, hot-rolled sections and bars, which are intended for use…

The objective of this document is to promote the harmonization of data and information reporting formats in order to provide the basis for the evaluation of occupational exposure with a view to allow for benchmarking capacity at the user level, technical review level, country level and global level (such as UNSCEAR) database or register on occupational exposure. Activity sectors and occupations (…

1 Scope 1.1 This Standard applies to portable luminaires, intended for use in dry, damp, and wet locations, and intended to be used in accordance with the Rules of CSA C22.1, Canadian Electrical Code, Part I, in non- hazardous locations, on a nominal 120 V system and 15 or 20 A branch circuits, or on the load side of a Class 2, LED Class 2, or safety extra-low voltage (SELV) circuit. 1.2 This…

1 Scope 1.1 Inclusions This Standard is intended for industrial air handling systems with the following characteristics: a) systems with energy consumption greater than 500 000 kWh per year; b) systems with air flow greater than 9.4 m3/s (20 000 cfm); c) air movement systems with a maximum energy output limit of 25 kJ/kg of air, which is equivalent to a maximum pressure ratio of 1.3 per…

1 Scope 1.1 General This Standard specifies energy efficiencies for liquid-filled distribution transformers. The total ownership cost (TOC) methodology is recommended as the means for achieving these energy efficiencies, particularly for use by electric utilities. This Standard also specifies an optimal method for non-utility users, based on a modified TOC methodology that meets the conditions…

1 Scope 1.1 This Standard specifies dimensional and safety requirements for recreational vehicles. Its purpose is to specify minimum criteria for providing a degree of protection against loss of life from fire and explosion. 1.2 The CSA Z240 RV Series of Standards does not apply to park model trailers. Note: Park model trailers are covered by the CAN/CSA-Z241 Series of Standards. 1.3 The…

1 Scope 1.1 General This Standard establishes criteria for emergency preparedness and response for the petroleum and natural gas industry systems. Note: Prevention, continuity, and recovery are addressed in other standards. 1.2 Applicability This Standard applies to petroleum and natural gas industry systems (see Figures 1and 2), including a) pipeline systems handling i) oil; ii) gas…

1 Scope 1.1 Purpose The purpose of this Standard is to provide criteria for the safe erection, use, and inspection of access scaffold (as covered in CSA S269.2 and engineered systems) and for the training of erectors and users of such equipment. 1.2 Subjects addressed This Standard applies to the erection, use, and inspection of access scaffold, and to training requirements for access…

1 Scope 1.1 General This Standard addresses the following aspects of cementitious materials: a) their definitions; b) their chemical, physical, and uniformity requirements; c) the tests required; d) the procedures for inspection and sampling; and e) the units of measurement, packaging, marking, and storage. 1.2 Classifications The cementitious materials for use in concrete are…
