1 Scope This standard describes the apparatus, test methods, and formulas to be used in carrying out the tests and calculations required by wire and cable standards. Note: Specific acceptance requirements are found in individual product standards.

IEC 62141:2005 specifies the track content, format, and recording method of the data blocks containing compressed video, AES3 audio data, and associated data which form the helical records on 12,65 mm tape in cassettes. This standard supports recording of source picture formats using 1920 x 1080 pixels with the 4:4:4 and 4:2:2 sampling structure specified in SMPTE 274M at the frame rate of 23,98…

Describes procedures for evaluating the ignition risk presented by electrostatic discharges from FIBC to flammable or explosive environments. The requirements of this standard are applicable to all types of FIBC, tested as manufactured, prior to usage, intended for use without liners in flammable or explosive environments with minimum ignition energy of more than 0,14 mJ, and where the charging…

Gives guidance on the supervision and maintenance of the quality of the insulating oil in electrical equipment. This standard is applicable to mineral insulating oils, originally supplied conforming to IEC 60296, and used in transformers, switchgear and other electrical apparatus where oil sampling is reasonably practicable and where the normal operating conditions specified in the equipment…

1 Scope 1.1 This Standard applies to the design, installation, operation, maintenance, and testing of emergency generators and associated equipment for providing an emergency power supply to electrical loads in buildings and facilities when the normal power supply fails and an emergency power supply is required by the National Building Code of Canada (NBC). Notes: (1) For guidelines on…

This National Standard of Canada is equivalent to International Standard ISO/IEC 15946-4:2004. 1 Scope ISO/IEC 15946 specifies public-key cryptographic techniques based on elliptic curves. These techniques include methods for the establishment of keys for symmetric cryptographic techniques, and digital signature mechanisms. The scope of this part of ISO/IEC 15946 is restricted to cryptographic…

This National Standard of Canada is equivalent to International Standard ISO/IEC 15962:2004. 1 Scope The data protocol used to exchange information in an RFID system for item management is specified in ISO/IEC 15961 and in this International Standard. Both International Standards are required for a complete understanding of the data protocol in its entirety; but each focuses on one…

This National Standard of Canada is equivalent to International Standard ISO/IEC 7811-7:2004. 1 Scope This part of ISO/IEC 7811 is one of a series of standards describing the characteristics for identification cards as defined in the definitions clause and the use of such cards for international interchange. This part of ISO/IEC 7811 specifies requirements for a high coercivity magnetic stripe…
