1.1 General This Standard provides a) maintenance procedures to reduce snow overload risk on existing buildings; b) monitoring, detection, and assessment methods for snow load risks on buildings; and c) procedures for snow removal. 1.2 Exclusions This Standard does not address a) specific requirements for the design or construction of new buildings subjected to snow loads; or b)…

1.1 This Standard applies to uninterruptible power supplies (UPS). The primary function of the UPS covered by this Standard is to ensure continuity of an alternating power source. The uninterruptible power supplies can also serve to improve the quality of the power source by keeping it within specified characteristics. 1.2 This Standard is applicable to movable, stationary, fixed, and built-in…

This part of IEC 61869 applies to new inductive voltage transformers for use with electrical measuring instruments and electrical protective devices at frequencies from 15 Hz to 100 Hz. NOTE 301 Requirements specific to three-phase voltage transformers are not included in this standard but, so far as they are relevant, the requirements in clauses 4 to 10 apply to these transformers and a few…

This Standard applies to unvented portable type gas camp heaters of the catalytic and infrared type only up to and including a maximum input of 12,000 Btu/hr (3 517 w) using propane, butane, and liquefied petroleum gas mixtures thereof, and intended for outdoor use. 1.2 This Standard applies to portable type gas camp heaters having a: a) regulated pressure; or b) non-regulated pressure. 1.…

1.1 This Standard sets out the minimum requirements for the design, construction, operation, maintenance, abandonment, and safety of wells and associated equipment used to inject waste into underground salt caverns in a slurry form. The equipment considered includes (a) wellhead and Christmas tree assemblies; (b) wells and subsurface equipment; and (c) safety equipment, including monitoring…

1 Scope and object This clause of Part 1 is applicable except as follows: 1.1.1 Equipment included in scope Replacement: Replace the existing text with the following: This part of IEC 61010 specifies safety requirements for METERS. The METERS that have a primary purpose of measuring voltage on a live MAINS CIRCUIT are within the scope of this standard. They have various names, but all of…

ISO/PAS 18167:2014 sets out the requirements for installing textile floor coverings (carpets). It gives details of the work necessary in preparing subfloor surfaces together with the procedures that are to be adopted where textile floor coverings are laid over various types of subfloors and underlays and where subfloor heating units are installed. NOTE This International Standard…

ISO/TS 17182:2014 describes the gas chromatographic determination of phenols, methyl phenols, di-methylphenols and tri-methylphenols (see Table 1) and selected chlorophenols (see Table 2) by using mass spectrometric detection in soil samples. This method can also be used for other solid samples, such as sediments and solid wastes. This International Standard describes an acidic liquid extraction…

ISO 11495:2014 describes a method for the determination of palladium in palladium jewellery alloys, preferably within the range of fineness specified in ISO 9202, by means of inductively coupled plasma optical emission spectrometry (ICP-OES). The preferred palladium content of the alloys lies between 500 ? (parts per thousand) and 950 ? palladium. NOTE This method can be used to analyse…
