ISO 20394:2007 specifies the equipment and procedures for determining the effect, on the mechanical properties and moisture content of a product, of the successive cycling of the product from dry conditions at -20 °C to wet conditions (water) at +20 °C. It is applicable to thermal-insulation products. The method is intended to simulate freeze-thaw effects on thermal-insulation products which are…

IEC 60068-2-82:2007 specifies whisker tests for electric or electronic components representing the finished stage, with tin or tin-alloy finish. However, the standard does not specify tests for whiskers that may grow as a result of external mechanical stress. This test method is employed by a relevant specification (international component or application specification) with transfer of the test…

This National Standard of Canada is based on International Standard CEI/IEC 60079-0:2004. 1 Scope This part of IEC 60079 specifies the general requirements for construction, testing and marking of electrical apparatus and Ex components intended for use in explosive gas atmospheres. Unless modified by one of the parts in the IEC 60079 series, electrical apparatus complying with this…

This CSA Standard is based on NIST (National Institute of Standards and Technology) Voluntary Product Standard PS 2, Performance Standard for Wood-Based Structural-Use Panels (December 2004). 1. SCOPE 1.1. This Voluntary Product Standard primarily establishes structural criteria for assessing the acceptability of wood-based structural-use panels for construction sheathing and single-floor…

ISO 10835:2007 gives the underlying theory,the basic principles for sampling and preparation of samples, andthe basic requirements for the design, installation and operation of sampling systems, for mechanical sampling, manual sampling and preparation of samples taken from a lot under transfer, to determine the chemical composition, moisture content and physical properties of the lot. The…

This National Standard of Canada is equivalent to International Standard ISO/IEC 11693:2005. 1 Scope This International Standard provides information necessary to store data on cards, to read data from cards, and for the physical, optical, and data interchangeability of optical memory cards in information processing systems. It defines the general characteristics of optical memory cards…

This National Standard of Canada is equivalent to International Standard ISO/IEC 11179-2:2005. 1 Scope This part of ISO/IEC 11179 restates and elaborates on the procedures and techniques of ISO/IEC 11179-3:2003 for registering classification schemes and classifying administered items in an MDR. All types of administered items can be classified, including object classes, properties,…

This National Standard of Canada is equivalent to International Standard ISO/IEC 7816-4:2005. 1 Scope This part of ISO/IEC 7816 specifies - contents of command-response pairs exchanged at the interface, - means of retrieval of data elements and data objects in the card, - structures and contents of historical bytes to describe operating characteristics of the card, - structures for…

This National Standard of Canada is equivalent to International Standard ISO/IEC 14496-12:2005. 1 Scope This International Standard specifies the ISO base media file format, which is a general format forming the basis for a number of other more specific file formats. This format contains the timing, structure, and media information for timed sequences of media data, such as audio/visual…
