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, inclusive. (Refer to…

The EDA Standards Roadmap Workshop was sponsored by the CAD Framework Initiative (CFI), Electronic Design Automation Companies (EDAC), and SEMATECH with participation by interested industry groups. The Workshop was specifically aimed at developing an industry-wide roadmap for development of design and test standards within Electronic Design Automation (EDA). There were three working groups, each…

1. Scope 1.1 The scope statement indicates which aspects and parts of pipeline systems and which service fluids are covered by the Standard. ? Carbon dioxide was added as a new service fluid in 1996. The definition of gas was changed in 1983 to accommodate the coverage of gaseous service fluids other than fuel gas and sour gas; however, until 1996, none had been added. ? The carbon…

Specifies a common application layer protocol (message structure, formats and transmission procedures) to be used at standard interfaces in alarm transmission systems. Should be used at all such interfaces where equipment from one supplier is intended to inter-work with equipment from other suppliers.

Specifies the transport layer message structure, formats and transmission procedures to be used at standard interfaces in alarm transmission systems. Should be used at all such interfaces where equipment from one supplier is intended to inter-work with equipment from other suppliers, and where the underlying system architecture does not provide the necessary facilities to support the common…

This National Standard of Canada is equivalent to International Standard CEI/IEC 1000-4-4:1995, first edition, 1995-01, including Amendment 1:2000. This International Standard relates to the immunity requirements and test methods for electrical and electronic equipment to repetitive electrical fast transients. It additionally defines ranges of test levels and establishes test procedures.…

This National Standard of Canada is equivalent to International Standard CEI/IEC 61000-4-2:1995+A1:1998 (edition 1.1, 1999-05). This International Standard relates to the immunity requirements and test methods for electrical and electronic equipment subjected to static electricity discharges, from operators directly, and to adjacent objects. It additionally defines ranges of test levels which…

This National Standard of Canada is equivalent to International Standard CEI/IEC 1000-4-12: 1995 (first edition, 1995-05). This section of IEC 1000-4 relates to the immunity requirements and test methods for electrical and electronic equipment, under operational conditions, to oscillatory waves represented by: (a) non-repetitive damped oscillatory transients (ring wave) occurring in low-voltage…
