Applies to a.c. circuit-breakers within the scope of IEC 60056 (Clause 1). It provides the general rules for testing a.c. circuit-breakers, for making and breaking capacities over the range of test-duties described in Subclauses 6.102 to 6.111 of IEC 56, by synthetic methods. The purpose of this standard is to establish criteria for synthetic testing and for the proper evaluation of results. Such…

Presents guidelines but not standards for establishing specifications for telecontrol systems and equipment following the other IEC standards on telecontrol systems and other relevant international standards and recommendations such as CCITT recommendations. Also facilitates the comparison of equipment produced by different manufacturers.

This part defines the most common symbols with the aim of standardizing and facilitating the use of terminology in standards for steel hollow sections and associated products. Five figures illustrate the meaning of the text. Annex A contains the bibliography.

This standard is valid for all types of implantable pacemakers and specifies as well the basic terms and definitions as the requirements for designation and packaging of pacemakers. In connection with the corresponding test methods minimum requirements are given for the ability of a pacemaker generator to resist adverse environmental conditions. The annexes A to F contain a code system for…

Deals with the use of the X.25 Packed Level Protocol (PLP) as defined in ISO 8280 operating over ISO 8802 Local Area Networks (LANs). The operation of the X.25/PLP using the Logical Link Control (LLC) Type 2 procedures is described in section 2. The operation of the X.25/PLP using the LLC Type 1 procedures is specified in section 3. To be used in compliance with the standards ISO 7498:1984; ISO…

This second edition cancels and replaces the first edition (1976). Specifies the principal dimensions of V-belts and the groove profiles of corresponding fixed or variable diameter pulleys. Is not applicable to belts used either as part of farm-machines which are standardized in ISO 3410, or for the propulsion of self-propelled vehicles.

Establishes general methods for calculating loads and principles to be used to select load combinations for proof of competence for the structural and mechanical components for cranes as defined in ISO 4306-1. Is based on rigid-body kinetic analysis and elasto-static analysis. Provides the general form, content and range of parameter values for more specific standards and also a framework for…
