Preface This is the third edition of CSA SPE-1000, Model code for the field evaluation of electrical equipment. It supersedes the previous editions published in 1999 and 1994. Introduction

0.1
Field evaluation of equipment in accordance with this Model Code should be undertaken only by fully qualified and competent persons. These persons should be experienced in conducting field evaluation and field testing of electrical and electronic equipment to Canadian safety requirements or other requirements acceptable to the authority having jurisdiction (AHJ). Because field evaluation of electrical equipment and products is conducted to the requirements of this Model Code, it is not equivalent to an evaluation in support of certification, which is conducted to the requirements of the applicable standard. Consequently, equipment and products that are field evaluated and labelled cannot be considered as certified. When used in conjunction with the requirements of the Canadian Electrical Code, Part I, this Model Code addresses the minimum requirements for equipment as they pertain to electrical safety. Where other authorities have jurisdiction, they must be consulted by the equipment owner or the owner's agent as to conformance to legislation. This legislation may be either federal, provincial, or municipal. This Model Code addresses the essential construction, marking, and test requirements that equipment must meet before it can be labelled. It allows for the evaluation of electrical equipment and products, with the objective of minimizing the risk of degrading the safety of the equipment through the procedures used in the field evaluation. Where the required tests involve procedures deemed to present a risk to the safety of the particular equipment, such tests may be carried out on a separate representative sample supplied for the sole purpose of testing. Alternatively, other means may be taken to determine conformance, such as the evaluation of relevant test data presented in support of an application for field evaluation. The requirements of this Model Code have been accepted by the AHJs.
