ISO 1519:2011 specifies an empirical test procedure for assessing the resistance of a coating of paint, varnish or related product to cracking and/or detachment from a metal or plastics substrate when subjected to bending round a cylindrical mandrel under standard conditions. For a multi-coat system, each coat can be tested separately or the complete system can be tested. The method specified can…

1 Scope 1.1 This Standard specifies the requirements for single-conductor and multiple-conductor thermoset-insulated wires and cables rated 600 V, 1000 V, 2000 V, and 5000 V, for use in accordance with the rules of the Canadian Electrical Code (CEC), Part 1, CSA C22.1, in Canada, Standard for Electrical Installations, NOM-001-SEDE, in Mexico, and the National Electrical Code (NEC), NFPA-70, in…

1.1 This Standard applies to rigid PVC conduit — type EB1 for encasement in concrete or masonry and type DB2/ES2 for direct burial or encasement in concrete or masonry — and associated fittings in accordance with the Rules of the Canadian Electrical Code, Part I, for ordinary locations. 1.2 The conduits and associated fittings covered by this Standard are intended for a maximum continuous…

1 Scope 1.1 This Standard describes the test procedures, test set-ups, and calculations required to determine the performance, capacities, energy consumption, and overall efficiency of gas-fired and oil-fired combined space and water heating systems (combos). 1.2 This Standard establishes laboratory methods for testing and rating the thermal performance and electrical energy use of a combo…

1 Scope 1.1 These Guidelines provide recommendations for the development of codes and standards used for the design and evaluation of civil engineering structures such as buildings, industrial structures, bridges, earthand water-retaining structures, towers, chimneys, and poles. These recommendations are intended to ensure the adequate and consistent provision of safety and serviceability,…

IEC 61850-7-3:2010 is applicable to the description of device models and functions of substations and feeder equipment. It specifies constructed attribute classes and common data classes related to substation applications. In particular, it specifies common data classes for status information, common data classes for measured information, common data classes for control, common data classes for…

IEC 60747-8:2010 gives standards for the following categories of field-effect transistors: - type A: junction-gate type; - type B: insulated-gate depletion (normally on) type; - type C: insulated-gate enhancement (normally off) type. The main changes with respect to the previous edition are listed below. a) "Clause 3 Classification" was moved and added to Clause 1. b) "Clause…

ISO 11771:2010 specifies a generic method for the determination and the reporting of time-averaged mass emissions from a specific installation or of a family of installations (or common source type), using data collected by measurements, and by establishing: mass emission rates by the simultaneous measurement of concentration and gas flow, using standardized manual or automatic methods, and also…

ISO 178:2010 specifies a method for determining the flexural properties of rigid and semi-rigid plastics under defined conditions. A standard test specimen is defined, but parameters are included for alternative specimen sizes for use where appropriate. A range of test speeds is included. The method is used to investigate the flexural behaviour of the test specimens and to determine the flexural…

Preface Standards development within the Information Technology sector is harmonized with international standards development. Through the CSA Technical Committee on Information Technology (TCIT), Canadians serve as the Canadian Advisory Committee (CAC) on ISO/IEC Joint Technical Committee 1 on Information Technology (ISO/IEC JTC1) for the Standards Council of Canada (SCC), the ISO member body…
