Scope:

This IEC second edition cancels and replaces the first edition published in 2012. This edition constitutes a technical revision.

This edition includes the following significant technical changes with respect to the previous edition:

a) The scope of the document has been clarified and limited to equipment below 500 kV.
b) Additional marking requirements for X-ray generating assemblies have been added.
c) Requirements for high-voltage cables used in the X-ray assembly have been added.
d) Insulation requirements have been added.
e) Temperature requirements for beam-limiting devices have been added.
f)  Clarification has been provided on PROTECTED EQUIPMENT and PARTIALLY PROTECTED EQUIPMENT, and test methods
g) Requirements for INTERLOCKS have been modified, taking into account functional safety standards.
h) Requirements for reasonably foreseeable misuse have been clarified.
i)  Risk assessment has been made mandatory for specific aspects.

This Part 2-091 is to be used in conjunction with the latest edition of IEC 61010-1. It was established on the basis of the third edition (2010) and its Amendment 1 (2016), hereinafter referred to as Part 1.

This Part 2-081 supplements or modifies the corresponding clauses in IEC 61010-1 so as to convert that publication into the IEC standard: Particular requirements for cabinet X-ray systems.

Where a particular subclause of Part 1 is not mentioned in this Part 2-081, that subclause applies as far as is reasonable. Where this Part 2-011 states "addition", "modification", "replacement", or "deletion" the relevant requirement, test specification or note in Part 1 should be adapted accordingly.

This is a proposed Amendment to C22.2 No. 94.1

1 Scope

1.1 This standard applies to enclosures for electrical equipment intended to be installed and used in non-hazardous locations in accordance with the Canadian Electrical Code, Part I, CSA C22.1, the provisions of the National Electrical Code, NFPA 70, and the provisions of Mexico's Electrical Installations, NOM-001-SEDE, as follows:

b)     Enclosures for indoor or outdoor locations, Types 3, 3X, 3R, 3RX, 3S, 3SX, 4, 4X, 6, and 6P.

1.2 This standard covers additional environmental construction and performance requirements for enclosures. The general requirements for enclosures are contained in CSA C22.2 No. 94.1, UL 50, and NMX-J-235/1-ANCE (See Annex B, Ref. No. 10) or the end-use product standards that are to be used in conjunction with this standard.

1.3 This standard does not cover the requirements for protection of devices against conditions such as condensation, icing, corrosion, or contamination that may occur within the enclosure or that may enter via conduit or unsealed openings.

1.4 Where an individual product standard contains requirements that are at variance with those of this standard, the requirements of the individual product standard take precedence.

1.  Scope

1.1 

This Standard establishes steady-state voltage operating ranges at point of connection for AC power systems in Canada. It serves to provide guidance:

a) To national committees on utilization and control equipment for establishing standard ratings of such equipment on a basis coordinated with power system voltages;

b) To power system designers so that new systems will be designed to accommodate standard ratings of equipment and devices;

c) To power system operators and to electrical energy users for determining suitable voltage performance and the need for corrective measures, with respect to existing systems, to accommodate current designs of equipment and devices; and

d) Towards a uniform system of voltage selections in the country without any suggestion that each utility will supply every voltage listed.  The establishment of standards on this basis is aimed at future development towards more uniformity on a national basis.

This Standard includes nominal voltages and supply steady-state voltage ranges at point of connection under both normal and extreme operating conditions. 

This standard does not cover voltage operating ranges at utilization points. (See Clause 6 for details)
