This International Standard provides recommendations for the design and implementation of electrical interlocks used actively or passively to prevent unsafe conditions or to ensure specific safe conditions and states during the operation of nuclear power plants. Safety system interlocks are covered by standards for safety systems. This standard gives design, reliability and test criteria arising from the consideration of interlocks important to safety in accordance with IEC 61226. It uses categories A, B and C as defined by that document. It takes into account the interlock safety significance and functions, and the role of the operator in some interlocks. Guidance is given on redundancy and on diversity of equipment for implementing interlocks, where high availability or integrity is involved, or where common mode failure may limit reliability. The use of computer-based equipment for interlock functions is discussed, and recommendations for diversity are given. Requirements for software and for verification and validation are given by reference to IEC 60880. The provision of test facilities is discussed together with self-testing and self-monitoring methods. The system of interlocks for a specific function includes the sensors of plant state (e.g., measuring devices and limit switches), the interlock and control power supplies, the control and instrumentation equipment providing the particular logic function for prevention or limitation of operation, and the cables, electromechanical features, key control and administrative control associated with the function.

Scope 1.1 This Standard applies to single-polarity connectors for use with all alloys of copper or aluminum, or copper-clad aluminum conductors, or all three, for providing contacts between current-carrying parts, in accordance with the Canadian Electrical Code, Part I, C22.1, in Canada, the National Electrical Code, NFPA-70, in the United States of America, or the Standard for Electrical Installations, NOM-001-SEDE, in Mexico, as follows: Note: Copper-clad aluminum conductors are for use only in the United States in accordance with the National Electrical Code, NFPA 70. a) pressure wire connectors intended to hold one or more conductor(s); b) connectors intended for use in appliances and equipment that comply with the requirements for such appliances and equipment; c) soldering connectors; d) splicing wire connectors intended for use with 4 AWG (21.2 mm2) or larger conductors; Note: A splicing wire and cable connector taking a range of conductor sizes may include conductor sizes smaller than 4 AWG (21.2 mm2). e) neutral bars; f) uninsulated connectors that are used in circuits rated 35 000 V and below; g) ampere-rated connectors not intended for general use; and h) insulation piercing connectors. 1.2 This Standard is intended for connectors suitable for use with conductors in the size ranges as follows: a) Aluminum 1) 12 AWG (3.3 mm2) and 10 AWG (5.3 mm2) solid; 2) 12 AWG (3.3 mm2) to 2 000 kcmil (1 010 mm2) stranded, Class B concentric, compressed, and compact; and 3) 12 AWG (3.3 mm2) to 1 000 kcmil (508 mm2) stranded single input wire (SIW). b) Copper-clad aluminum 1) In Canada, this construction is not allowed. 2) In Mexico, this construction is not allowed. 3) In the United States: i) 12 AWG (3.3 mm2) and 10 AWG (5.3 mm2) solid; and ii) 12 AWG (3.3 mm2) to 2 000 kcmil (1 010 mm2) stranded, Class B concentric, compressed, and Class C concentric. c) Copper 1) 30 AWG (0.05 mm2) to 10 AWG (5.3 mm2) solid; and 2) 30 AWG (0.05 mm2) to 2 000 kcmil (1 010 mm2) stranded, Class B concentric and compressed, and Class C concentric. d) Compact-stranded copper conductors 1) in Canada for 8 AWG (8.4 mm2) and larger; 2) in the United States for 2 AWG (33.6 mm2) and larger; and 3) in Mexico for 8 AWG (8.4 mm2) and larger. e) Rigid (solid and stranded) metric wire falling within the ranges of the above AWG sizes. Note: For example, a connector rated for 6 AWG - 250 kcmil may be additionally rated for 16 - 120 mm2. f) Other class and strand configurations as indicated by marking. 1.3 This Standard is intended for connectors suitable for currents not exceeding the ampacity of insulated conductors rated 75°C or 90°C in accordance with the rating of the connector, if provided. 1.4 In the United States and Mexico, these requirements cover insulated connectors, insulating caps, and covers intended for use at 600 volts or less (1 000 volts in a sign or luminaire) and uninsulated connectors for use in general use circuits rated 2 000 volts nominal or less. In Canada, these requirements cover insulated connectors, insulating caps, and covers intended for use at 600 volts or less (1 000 volts in a sign or luminaire) and uninsulated connectors for circuits rated 2 000 volts phase-to-phase or less. Uninsulated connectors may also be used in applications up to 5 000 volts phase-to-phase where allowed and installed in accordance with Section 36 of the Canadian Electrical Code, Part I, C22.1. 1.5 This standard also applies to uninsulated connectors (both terminal and splicing types) for use in circuits rated 35 000 volts or less. 1.6 This Standard does not apply to: a) insulated connectors for voltage levels above 600 V (1 000 V in a sign, lighting fixture, or luminaire); b) manual twist-on connectors; c) built-in terminal connectors in devices rated less than 30 A intended for outlet box mounting or having provision for stress relief; d) flat quick connect terminals; and e) wire binding screw terminals.

5.1 Failure of microelectronic devices is often due to failure of an interconnection bond. A common type of interconnection bond is a wire bond. These methods can assist in maintaining control of the process of making wire bonds. They can be used to distinguish between weak, nonadherent wire bonds and acceptably strong wire bonds. The methods are destructive. 5.2 These test methods are appropriate for on-line use for process control, for purchase specifications, and for research in support of improved yield or reliability. The referee method should be used for quantitative comparison of pull strengths of wire bonds. 1.1 These test methods cover tests to determine the pull strength of a series of wire bonds. Instructions are provided to modify the methods for use as a referee method. The methods can be used for wire bonds made with wire having a diameter of from 0.0007 to 0.003 in. (18 to 76 ??m). Note 1???Common usage at the present time considers the term ???wire bond??? to include the entire interconnection: both welds and the intervening wire span. 1.2 These test methods can be used only when the loop height of the wire bond is large enough to allow a suitable hook for pulling (see Fig. 1) to be placed under the wire. FIG. 1 Suggested Configuration for a Pulling Hook 1.3 The precision of these methods has been evaluated for aluminum ultra-sonic wedge bonds; however, these methods can be used for gold and copper wedge or ball bonds.2 1.4 These methods are destructive. They are appropriate for use in process development or, with a proper sampling plan, for process control or quality assurance. 1.5 A nondestructive procedure is described in Practice F458. 1.6 The values in SI units are to be regarded as standard. 1.7 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
