1 Scope 1.1 This Standard specifies requirements for the design and performance of complete active fall-protection systems, including travel-restraint and vertical and horizontal fall-arrest systems. This Standard is intended for engineers with expertise in designing fall-protection systems. 1.2 This Standard does not specify design or performance requirements for fall-arrest equipment or…

1 Scope 1.1 General This Standard addresses the special requirements of plumbing systems pertinent to the design, construction, operation, and maintenance of health care facilities (HCFs). This Standard specifies requirements for the following in HCFs: a) water supply systems, including cold water systems and hot water systems; b) plumbing fixtures and fittings; c) drainage systems; d)…

1.1 This Standard covers prefabricated gravity grease interceptors made of concrete, fiber-reinforced polyester (FRP), thermoplastic, or steel and specifies requirements for design, materials, performance, testing, and markings. 1.2 The requirements of this Standard are not intended to prevent the use of alternative materials or methods of construction provided such alternatives meet the…

This document specifies a method for the evaluation of the buckling load which: a) takes into account a geometric model of the hydraulic cylinder, meaning it does not treat the hydraulic cylinder as an equivalent column, b) can be used for all types of cylinder mounting and rod end connection specified in Table 2, c) includes a factor of safety, k, to be set by the person performing the…

IEC 60700-1:2015+A1:2021 applies to thyristor valves with metal oxide surge arresters directly connected between the valve terminals, for use in a line commutated converter for high voltage d.c. power transmission or as part of a back-to-back link. It is restricted to electrical type and production tests. The tests specified in this standard are based on air insulated valves. For other types of…

This document establishes design evaluation requirements and recommendations for absorbable cardiovascular implants used to treat vessels and/or the vascular space within the circulatory system, including the heart and all vasculature. This document is intended to supplement device-specific standards by providing guidelines specific for either absorbable implants or components, or both. This…

This document specifies a chassis dynamometer test procedure to determine the end of the charge-depleting state (CD) and consumed electric energy during CD state. The identification of the end of the CD state is an important step for procedures to determine exhaust emissions and fuel consumption. Final determination of exhaust emissions and fuel consumption is not included in this document. This…
