This document is a service definition that provides an abstract description of the application programming interface (API) seen by an Application Process using a distributed inter-process communication (IPC) facility (DIF). APIs reflect the specific constraints and conventions of an operating system or programming language. This document does not do that. A service definition specifies the…

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 (…

IEC 60079-17:2023 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. IEC 60079-17:2023 applies to users and covers only those factors directly related to the inspection and maintenance…

1 Scope 1.1 Purpose The purpose of this Standard is to minimize the risk of personal injury by providing minimum requirements for the design, construction, installation, inspection, and maintenance of the mechanical refrigeration systems and volatile direct refrigeration systems specified in Clauses 1.2.1and 1.2.2. Note: This Standard does not directly address protection of property and…

1 Scope 1.1 Inclusions This Code applies to a) the design, location, construction, operation, operator training, and maintenance of CNG vehicle refuelling stations; and b) CNG bulk transport filling and decanting stations, including i) those that are fixed or mobile and intended for private or public dispensing operations; and ii) bulk transport filling and decanting stations that feed…

1 Scope 1.1 Inclusions This Code applies to a) the design, location, construction, operation, operator training, and maintenance of LNG refuelling stations; b) LNG mobile refuelling units (MRUL) or LNG portable refuelling units (PRUL) with single containment storage tanks up to 265 m3 (70 000 gal) water capacity employed for vehicle LNG dispensing operations; c) shop-fabricated and…

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…
