It includes reference publications, definitions, abbreviations, general…

1 Scope 1.1 General This Standard covers steel valves primarily intended for use in oil or gas pipeline systems. The following types of valves are covered: (a) gate valves; (b) plug valves; (c) ball valves; and (d) check valves. 1.2 Size, nominal pressure class, and category 1.2.1 Size This Standard covers valves in sizes from NPS 2 to NPS 60. (See Table .1.) 1.2.2 Nominal pressure class This…

1 Scope This International Standard is applicable to fully insulating spliced or hook ladders with extension or having a combination of insulating and conductive sections and used for live working on a.c. or d.c. electrical installations at 1 000 V and above for a.c. and 1 500 V and above for d.c. The ladders are classified functionally as Category 1 and Category 2. This standard concerns only…

1 Scope This International Standard is applicable to flexible insulating covers (line hoses) for the protection of workers from accidental contact with live or earthed electrical conductors and for the avoidance of short circuits during live working. 1.1 Classes Five classes of conductor covers, differing in electrical characteristics, are provided and designated as class 0, class 1, class 2,…

1. SCOPE 1.1 This standard applies to immersion suit systems for marine abandonment and constant wear. This standard applies to suit systems that reduce thermal shock upon entry into cold water; delay the onset of hypothermia during the immersion in cold water; provide acceptable flotation and minimize the risk of drowning; do not impair the wearer's ability to perform fundamental survival…

Describes methods for a test which simulates the acoustical effects of a median adult wearer on the performance of a hearing aid. Establishes certain guidelines for simulated in situ measurements of hearing aids; it describes a simplified method for simulated in situ measurements of hearing aids and a description for determination of the directivity index (DI) of directional microphones in…

This National Standard of Canada is equivalent to International Standard ISO/IEC TR 21000-1:2004. 1 Scope This Technical Report has been prepared within ISO/IEC JTC 1/SC 29/WG 11 to reflect the progress made on the definition of the MPEG-21 Multimedia Framework. This progress is a result of the combination of WG 11's efforts to standardise the parts of the multimedia framework where…

1 Scope This part of ISO/IEC 18012 specifies requirements for product interoperability in the area of home and building automation systems. It specifies layers six and seven of the OSI reference model (see ISO/IEC 7498-1) with sufficient detail needed to design interoperable home electronic system products, while layers one to five are only specified to the point needed to check whether devices…

ISO 22853:2005 specifies the XML application MSML (Maritime Safety Markup Language). MSML is a language for structuring information and the goal is to create an open standard that can be used generally in the maritime sector. MSML is implemented using XML Schema, which is contained in a separate document that could be used at validation. The first purpose of MSML is to make it possible to record…

ISO/PAS 17001:2005 contains principles and requirements for the element of impartiality as it relates to standards for conformity assessment. It is an internal tool for use in the ISO/IEC standards development process by ISO/CASCO working groups when considering the element of impartiality in preparation of their documents. ISO/PAS 17001:2005 is not a stand-alone normative document to be used…
