In keeping with CSA Group’s goal of harmonizing its standards with those of other countries to the greatest extent possible, CSA’s Technical Committee on Boilers and Pressure Vessels and its Subcommittees have, in the course of developing this Standard, worked closely with the National Board of Boiler and Pressure Vessel Inspectors in the United States and with the American Society of Mechanical Engineers (ASME) committees responsible for producing the National Board Inspection Code and ASME’s Boiler and Pressure Vessel Code. This Standard contains requirements for boilers, pressure vessels, pressure piping, and fittings. It is intended mainly to fulfill two objectives: first, to promote safe design, construction, installation, operation, inspection, testing, and repair practices; and second, to facilitate adoption of uniform requirements by Canadian jurisdictions. This Standard has undergone substantial technical and editorial revisions since the previous edition in 2019. The requirements in this edition have been reorganized in a lifecycle format, with four new clause titles: Conformity assessment and quality control systems (Clause 4); Classification of equipment (Clause 5); Equipment manufacturing (Clause 6); and Owner’s equipment (Clause 7). Significant changes include the following: a) the requirements of Part 2 in CSA B51:19 have been removed to reflect their inclusion in CSA HGV 2 and CSA NGV 2; b) the requirements of Part 3 in CSA B51:19 have been incorporated throughout this Standard; c) new requirements in Clauses 5.1.1.8 to 5.1.1.10 for boilers in cyclic service have been added; d) a new Clause (Clause 5.2.4.13) with design guidance for superheated steam sources connected to blowoff vessels has been added; e) new definitions and Clauses (Clauses 6.1.1 and 7.1.2) laying out responsibilities for manufacturers have been added; f) new references to ISO 16528-1 have been added to Clause 6.2.1.1; g) references to a CCRN or similar organization have been removed; h) revisions have been made to address carbon steel toughness requirements, now found in Clause 6.2.6, and in a deletion of notes to Clause 5.2.1; i) new test requirements for carbon steel pipe, fittings, and forgings in Clause 6.3.7 have been added; j) requirements for welded staybolts, previously found in Clause 6.8 in CSA B51:19, have been removed; k) additions to the Table 5 Note on in-situ testing have been included; l) Clause C.1.1 has been updated to clarify certificate of authorization requirements for safety, relief, or safety relief valves; m) Clause C.2.2.8 regarding PRD-certified assemblers or distributors has been revised; n) the Statutory Declaration form has been replaced with a new Declaration of Conformity form (see Figure D.6); o) a new CRN application form has been added (see Figure D.9); p) revisions to Annex F including i) replacing references to "statutory declaration" with "declaration of conformity"; ii) new informative clauses for quality programs; and iii) Annex F now titled "Quality programs for manufacturers of boilers, pressure vessels, piping systems and fittings"; q) Annex G has been revised to bring the annex into alignment with CSA B149.5; r) Clause I.6, providing optional requirements for servicing historical boilers, has been revised; s) the Standard has been revised throughout to allow references to ASME Code Section XIII and use of term ASME Code certification mark with designator; t) the addition of new annexes including i) Annex M, "Pneumatic testing of pressure vessels and piping systems"; ii) Annex N, "Quality program requirements for performing new construction inspection"; iii) Annex O, "Guidelines for a quality program for organizations that provide design examination services"; iv) Annex P, "Guidelines for audit programs"; v) Annex Q, "Guidelines for the development and operation of a Pressure Equipment Integrity Management Program (IMP)"; vi) Annex R, "Synopsis of some exemptions in Canadian jurisdictions"; vii) Annex S, "Guidelines for registration documentation and inspections for new construction"; and viii) Annex T, "Recommended safe practices where hydrogen is a constituent of the service fluid". CSA Group acknowledges that the development of this Standard was made possible, in part, by the financial support of Natural Resources Canada. The users of this Standard should note it is a recommendatory document only and does not have the force of law except where it has been officially adopted by a Canadian jurisdiction. Users should also note that adoption does not necessarily mean the Standard has been adopted unchanged. For example, a jurisdiction may decide to make an informative annex normative. The Technical Committee intends to meet periodically to review this Standard and, if necessary, to revise it to meet changing conditions and maintain uniformity of practice throughout Canada. The Technical Committee supports the use of the National Board Inspection Code. It is the responsibility of users of this Standard to be aware that applicable local regulations can take precedence over the requirements of that Code. This Standard was prepared by the Technical Committee on Boilers and Pressure Vessels, under the jurisdiction of the Strategic Steering Committee on Mechanical Industrial Equipment Safety, and has been formally approved by the Technical Committee. This Standard has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group.

CSA SPE-1000-2021
Model Code for the field evaluation of electrical equipment
Preface This is the fifth edition of CSA SPE-1000, Model Code for the field evaluation of electrical equipment . It supersedes previous editions published in 2013, 2009, 1999, and 1994. Significant changes in this edition include new requirements for the field evaluation of high-voltage transformers, skids, lasers, non-medical X-rays, cosmetic and hygiene products, and non-residential equipment producing ozone. Clauses formerly located in Annex A, General requirements for electrical equipment, have been moved to the body of the Model Code. This Model Code is based upon guidelines for special inspections. These guidelines have been in effect for many years with a good safety record. The Canadian Advisory Council on Electrical Safety strongly supports the continuation of special inspections of electrical equipment, with the stipulation that the requirements be formally published. Field evaluation of electrical equipment in accordance with the requirements of this Model Code is intended to be conducted by an inspection body accredited by Standards Council of Canada (SCC). Inspection body accreditation is the process of assessing and publicly recognizing the integrity, reliability, and technical competence of an organization’s inspection services. Accreditation of an organization’s inspection services by the SCC is a means of demonstrating that those services (within the scope of their formal accreditation) conform to an accepted set of requirements. Field evaluation provides a means for evaluating electrical equipment, and if found to conform to the requirements of this Model Code, such electrical equipment may be marked with a field evaluation label. It is always within the purview of the authority having jurisdiction (AHJ) in whose jurisdiction the Model Code is applied, to add technical or administrative requirements, stipulations, or deviations to this Model Code. Typically, AHJs base their official acceptance of electrical equipment and products upon certification by an SCC-accredited certification body that the equipment conforms to the applicable standards. The certification body bases its certification upon testing and evaluation of a representative sample of equipment as manufactured to the relevant equipment standard (known as type or prototype testing). Certification is granted if the sample is found to be in conformance and a follow-up inspection program is put in place to ensure continued conformance. This Model Code does not deal with type (or prototype) testing of equipment as practised in a regular certification program. It addresses minimum construction, marking, and test requirements that are consistent with maintaining a level of safety for electrical equipment and products so as not to present an undue hazard (as defined in this Model Code) to persons or property. This Model Code does not address the efficacy, performance, or quality of electrical equipment and products. This Model Code was developed by a Working Group of the Canadian Advisory Council on Electrical Safety (CACES) Subcommittee on SPE-1000, and was approved by CACES. Scope 1.1 1.1.1 This Model Code provides construction, testing, and marking requirements for the field evaluation of electrical equipment by an inspection body, where certification of that equipment is impracticable or otherwise unavailable. 1.1.2 The field evaluation of equipment found to be in conformity with the requirements of this Model Code, by SCC accredited organizations, is deemed an accepted form of approval of electrical products by the authority having jurisdiction. 1.1.3 Notwithstanding the requirements of Clauses 1.1.1and 1.1.2, field evaluation is not intended to serve as a substitute for certification. 1.2 The following are examples of where this Model Code applies: a) custom-built equipment for special applications; b) equipment manufactured on a non-repetitive basis; c) equipment sold in quantities of not more than 500 on a national basis, per model, per year, per inspection body; d) equipment not obtainable as "certified" under a regular certification program; e) equipment already installed or ready for use on-site and awaiting approval in accordance with the Canadian Electrical Code, Part I; f) complete systems or subassemblies that are all available for examination and testing during the evaluation process; and g) other electrical equipment as determined by the AHJ. Note: Where it is unclear or there is uncertainty as to whether the electrical equipment is to be field evaluated under the classifications of this Clause, the AHJ should be consulted for clarification. 1.3 This Model Code applies where the requirements are supplemented by requirements of particular equipment Standards, where referenced, and the installation requirements of the Canadian Electrical Code, Part I, as applicable. 1.4 This Model Code applies to equipment that may be evaluated at a client’s facilities or at other specified locations, including the location of equipment installation. 1.5 This Model Code is not intended to apply to the re-evaluation of equipment that has been rejected due to the results of a previous evaluation conducted by a certification or inspection body through any other existing certification or inspection service. 1.6 This Model Code does not apply to the field evaluation of a) wire and cable products; b) wiring devices; c) equipment for use in hazardous locations; d) medical electrical equipment and systems; e) components* that will require further evaluation as part of a complete assembly, such as switches, relays, and timers; f) equipment, other than transformers, connected to line voltage in excess of 46 kV; g) manlifts, elevators, climb assists and similar systems (other than their associated control panels); and h) any equipment that is not permitted to be field evaluated as directed by an AHJ (such as residential air-cleaning equipment that intentionally produces ozone). * Special inspection/field evaluation only applies to equipment that is capable of being connected to the supply in accordance with the Canadian Electrical Code, Part I. 1.7 General requirements applicable to this Model Code are given in CAN/CSA-C22.2 No. 0, General Requirements — Canadian Electrical Code, Part II. 1.8 In this Model Code, "shall" is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with this Model Code; "should" is used to express a recommendation or that which is advised but not required; and "may" is used to express an option or that which is permissible within the limits of this Model Code. Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material. Notes to tables and figures are considered part of the table or figure and may be written as requirements. Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application. 1.9 In accordance with Clause 1.8, this Model Code has been written in mandatory language to facilitate its adoption where users of the Model Code or regulatory authority wish to do so.
