Defines standard procedures for calibrating optical fibre chromatic dispersion test sets. The procedures apply to calibration laboratories, and to manufacturers and users of CD test sets, for: (a) calibrating CD test sets, (b) setting specifications of CD test sets, (c) extending the calibration period of an already calibrated CD test set. It applies to all CD test sets, except for multimode…

Specifies general safety requirements for electrical equipment intended for professional, industrial process, and educational use. It applies to 4 main groups of equipment: (a) Electrical test and measurement equipment such as signal generators, measurement standards, power supplies, transducers, transmitters, etc. (b) Electrical control equipment to control specific values by manual setting,…

This part of ISO 10303 specifies the abstract test methods for conformance testing of an implementation of an ISO 10303 Application Protocol (AP). The scope is limited to the following implementation methods: — preprocessors that claim to generate 10303 schema instances represented as exchange structures as defined by ISO 10303-21; — postprocessors that claim to accept and process 10303 schema…

This part of ISO 8529 specifies the reference neutron radiations, in the energy range from thermal up to 20 MeV, for calibrating neutron-measuring devices used for radiation protection purposes and for determining their response as a function of neutron energy. Reference radiations are given for neutron fluence rates of up to 1 _ 109 m?2_s?1, corresponding, at a neutron energy of 1 MeV, to dose-…

1. SCOPe 1.1 This Standard specifies requirements for treated wood-based cellulose fibre intended for use as thermal insulation (cellulose fibre insulation, CFI) in new and existing buildings within the temperature range of -60°C to 90°C. 1.2 This Standard describes general requirements for the material and additional requirements specific to applications. The applications are…

B64.0-01 Definitions, General Requirements, and Test Methods for Vacuum Breakers and Backflow Preventers 1. Scope 1.1 Vacuum breakers and backflow preventers that are specified in the B64 Series of CSA Standards include only those devices that are designed for use in potable water supply systems to prevent cross-connections. 1.2 This Standard provides definitions, general…

This International Standard specifies the framework, concepts and methodology for testing and criteria to be achieved to claim conformance to the family of ISO geographic information standards. It provides a framework for specifying abstract test suites (ATS) and for defining the procedures to be followed during conformance testing. Conformance may be claimed for data or software products or…

This International Standard specifies an infrared absorption method, after combustion in an induction furnace, for the determination of the total carbon and sulfur content in steel and iron. The method is applicable to carbon contents of mass fraction between 0,005 % and 4,3 % and to sulfur contents of mass fraction between 0,000 5 % and 0,33 %. This method is intended to be used in normal…

1. Scope and Purpose 1.1 Scope 1.1.1 This Standard applies to packaged heat/energy-recovery ventilators (HRV/ERV) that comprise factory-assembled elements including fans or blowers, in which heat or heat and moisture is transferred between two isolated airstreams. 1.1.2 This Standard specifies laboratory methods of testing and procedures for rating the apparent effectiveness and…
