1 Scope Replacement: This International Standard deals with all aspects of safety such as electrical, thermal and mechanical. This part 2-13 of IEC 61558 applies to stationary or portable, single-phase or polyphase, aircooled (natural or forced), independent or associated auto-transformers, having a rated supply voltage not exceeding 1 000 V a.c., a rated frequency not exceeding 500 Hz…

1 Scope 1.1 Scope This Standard specifies requirements for controlling hazardous energy associated with potentially harmful machines, equipment, and processes (including mobile machinery and equipment; see Annex M). Where a CSA Standard or other recognized Standard exists for a specific type of machinery, equipment, or process, it should be used with this Standard to provide the most effective…

1 Scope 1.1 This Standard specifies requirements for thermoplastic pressure piping. It includes reference publications, definitions, abbreviations, general requirements for materials and manufactured pipe and fittings, relevant test methods, and marking requirements. Notes: 1) The terms “pipe” and “piping”, as well as “tube” and “tubing”, are used interchangeably in the CSA B137 Series. 2…

1 Scope This document specifies a data interchange format that can be used for storing, recording, and transmitting digitized acoustic human voice data (speech) assumed to be from a single speaker recorded in a single session. This format is designed specifically to support a wide variety of Speaker Identification and Verification (SIV) applications, both text-dependent and text-independent,…

1 Scope This part of ISO/IEC 29167 defines the architecture for security services for the ISO/IEC 18000 air interfaces standards for radio frequency identification (RFID) devices. Its purpose is to provide a common technical specification for optional security services for RFID devices that may be used by ISO committees developing RFID application standards. This part of ISO/IEC 29167…

1 Scope This part of ISO/IEC 29167 defines the crypto suite for PRESENT-80 for the ISO/IEC 18000 air interfaces standards for radio frequency identification (RFID) devices. Its purpose is to provide a common crypto suite for security for RFID devices that can be referred by ISO committees for air interface standards and application standards. PRESENT-80 is a symmetric block cipher that can…

1 Scope This document defines a coding suite based on an exclusive or (XOR) operation for the ISO/IEC 18000 air interfaces standards for radio frequency identification (RFID) systems. In particular, it specifies the use of XOR as a basic way to hide plain data in the identity authentication and secure communication procedures. The coding suite is defined in alignment with existing air interfaces…

1 Scope Replacement: This part of IEC 61558 deals with the safety of isolating transformers for general applications and power supply units incorporating isolating transformers for general applications. Transformers incorporating electronic circuits are also covered by this standard. NOTE 1 Safety includes electrical, thermal and mechanical aspects. Unless otherwise specified, from here…
