Information technology — Open Systems Interconnection — Basic Reference Model: The Basic Model
Cancels and replaces the first edition (1984). The model provides a common basis for the coordination of standards development for the purpose of systems interconnection, while allowing existing standards to be placed into perspective within the overall Reference Model. The model identifies areas for developing or improving standards. It does not intend to serve as an implementation specification.
Magnetic materials - Part 8: Specifications for individual materials - Section 10: Specification for...
This standard specifies the general requirements, magnetic properties, geometric characteristics and tolerances as well as inspection procedures for magnetic materials used primarily for relays. The standard applies to pure iron and steel products generally delivered in the semi-processed state.
Tests on indoor and outdoor post insulators of ceramic material or glass for systems with nominal vo...
Applies to post insulators and post insulator units of ceramic material or glass for indoor and outdoor service in electrical installations or equipment operating on alternating current with a nominal voltage greater than 1 000 V and a frequency not greater than 100 Hz. Notes: -May also be regarded as a provisional standard for insulators for use on d.c. systems, see IEC 60438. -When considering…

associated with…
This National Standard of Canada is equivalent to International Standard ISO
2424:1992.
1 Scope
This International Standard gives definitions of terms relating to textile
floor coverings, and defines categories of these products.
Application guide for ISO 10755, ISO 10756, ISO 10757, ISO 10758 and ISO 10759
Intended to assist users to understand the application of these standards. Gives particular notes to the individual standards and describes certain assumptions made during the development of these specifications.
Optics and optical instruments — Environmental requirements — Part 6: Test requirements for medical ...
Applies to optical instruments and instruments with optical components in the field of medicine. Specifies requirements to be met with regard to the resistance of the optical, mechanical, chemical and electrical properties or performance data of the instruments influences and hence stipulates geographical and technical areas of application. Forms the basis for the specification of environmental…
