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…

Scope This National Standard specifies minimum requirements for preparing, developing, and conducting challenge-based, agile and open procurement of digital products and services. This Standard defines a framework for organizations evaluating the suitability of digital product and service providers using “challenge-based” criteria. This methodology requires organizations sourcing digital,…

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…

ISO 14044 requires the goal and scope of an LCA to be clearly defined and be consistent with the intended application. Due to the iterative nature of LCA, it is possible that the LCA scope needs to be refined during the study. This document specifies methodologies that can be applied to determine the carbon footprint of a product (CFP) or partial CFP of a hydrogen product in line with ISO 14067.…

This document specifies methods for the measurement of pumping characteristics of non-evaporable getters (NEGs). It is applicable to all sizes and all types of NEGs, including those: —    with the shape of pill, disk, ring, strip, module, cartridge; —    with pump structures; —    and NEG coatings on inner surface of pipes and vacuum chamber. A significant difference of pumping characteristics of…
