Scope 1.1 These requirements apply to portable germicidal equipment intended to expose the air and surfaces within an unoccupied area with uncontained ultraviolet (UV) energy. These requirements address equipment intended to remain stationary while in operation, and intended for use by ordinary persons. The equipment may also produce visible light. 1.2 In this Standard, the UV overexposure…

1 Scope 1.1 Introduction This Standard describes the test procedures, test set-ups, and calculations required to determine the performance, capacities, energy consumption, and overall efficiency of gas-fired and oil-fired combined radiant space and water heating systems (combos) with hydronic heat distribution. 1.2 Type of standard This Standard establishes laboratory methods for testing and…

IEC 62053-22:2020 applies only to transformer operated static watt-hour meters of accuracy classes 0,1 S, 0,2 S and 0,5 S for the measurement of alternating current electrical active energy in 50 Hz or 60 Hz networks and it applies to their type tests only. This document applies to electricity metering equipment designed to: • measure and control electrical energy on electrical networks (mains…

1 Scope 1.1 This Standard applies to all types of laboratory fume hoods, including ductless fume hoods. The following clauses are not relevant to ductless fume hoods: 4.3.6, 4.3.7, 4.3.8, 4.4, 5.3.5.1, 7.2, and 10.3.2.4l) to p). Note: Ductless fume hoods should not be considered acceptable substitutes for ducted fume hoods. They may be suitable alternatives provided there is an application-…

1.1 This Standard has been developed for the assessment of volatile organic compound emissions from polyurethane foam materials used in residential and nonresidential occupancies. It outlines a test procedure for the determination of volatile organic compounds from the specimen and explains why certain test conditions have been selected. 1.2 This laboratory test method is based on ASTM D5116…

IEC 61482-1-1:2019 specifies test method procedures to determine the arc rating of flame resistant clothing materials and garments or assemblies of garments intended for use in clothing for workers if there is an electric arc hazard. An open arc under controlled laboratory conditions is used to determine the values of ELIM, ATPV or EBT of materials, garments or assemblies of garments. NOTE 1 …

1 Scope 1.1 This Standard covers control units, fire alarm systems and control unit accessories for use in accordance with the Standard for the Installation of Fire Alarm Systems, CAN/ULC-S524, in accordance with CSA-C22.1, Safety Standard for Electrical Installations, Canadian Electrical Code, Part I; and the National Building Code of Canada. 1.2 This Standard also covers smoke control…

This document describes procedures to measure outgassing rates from components designed for vacuum chambers and of vacuum chambers as a whole. The outgassing rates are expected to be lower than 10−5 Pa m3 s−1 (10−2 Pa L s−1) at 23 °C and to emerge from devices that are suitable for high or ultra-high vacuum applications. The molecular mass of the outgassing species or vapour is below 300 u. The…

quality in terms of characteristics defined in ISO/IEC 25012. This International Standard contains the following: — a basic set of data quality measures for each characteristic; — a basic set of target entities to which the quality measures are applied during the data-life-cycle; — an explanation of how to apply data quality measures; — a guidance for organizations defining their own measures for…

ISO 14224:2016 provides a comprehensive basis for the collection of reliability and maintenance (RM) data in a standard format for equipment in all facilities and operations within the petroleum, natural gas and petrochemical industries during the operational life cycle of equipment. It describes data collection principles and associated terms and definitions that constitute a "reliability…
