Specifies the majority of tolerances on dimensions used by ISO/TC 5/SC 1 in drawing up International Standards concerning steel tubes. Is intended for use as a basic document by all ISO technical committees concerned with the standardization of steel tubes. It cannot, therefore, be used as a standard for the definiton of a product. This second edition cancels and replaces the first edition (1977…

1. Scope 1.1 General This Standard establishes limits and methods of measurement of the immunity of radio and television broadcasting receivers and certain associated equipment to degradation of performance due to electromagnetic disturbances. 1.2 Applicability This Standard is applicable to immunity of two classes of equipment from degradation of performance resulting from…

1. Scope 1.1 This Standard specifies technical requirements for (a) the interconnection of WECS to an electric utility; (b) the installation and operational specifications to be provided to the utility by those proposing interconnection to the utility; (c) the system protection including manual and automatic disconn ect switches, transformers, fault protection devices, relays and…

General Introduction One of the key requirements before organizations can exchange administrative, commercial and transport information between their computers, without manual intervention, is agreement on the content and structure of the information to be transmitted. In EDIFACT, this is achieved by developing United Nations Standard Electronic Messages (UNSM's), for both national and…

1. Scope 1.1 This Standard is complementary to CSA Standard CAN3-B78.1, and covers dimensioning and tolerancing of products depicted on technical drawings. 1.2 Some of the technical terms dealing particularly with dimensioning and tolerancing are defined in Clause 3. Abbre viations commonly used on drawings are given in CSA Standards Z85, CAN3-B78.1 and CAN3-B78.3. 1.3 Although…

Facilitates identification, by class, of drugs in syringes filled by the user, used in anaesthesia and critical care.
