Preface
This Standard is the first edition of No, 0.6 of a series of Standards issued by Canadian Standards Association under Part II of the Canadian Electrical Code. This Standard is part of the Requirements for Safety of Electrical Products segment of CSA's Electrical program and is identified as such by the Electrical symbol on the front cover.
This Standard provides test procedures for assessing the flammability properties of polymeric materials, used in electrical equipment in response to heat and flame under controlled laboratory conditions.
The requirements are written in the spirit of guidelines that may be referenced by interested groups such as the Subcommittees of Part II of the Canadian Electrical Code, in their standards-writing activities. The predominant utilization of the test procedures included in this Standard should serve to standardize the diversified test requirements for flammability properties of polymeric materials that appear in existing Standards.
The CSA Subcommittee on Standard C22.2 No. 0.6 plans to supplement these requirements in due course in the following areas: mechanical properties, electrical properties, moisture absorption, thermal stability, and products of combustion.
For general information on the Standards of the Canadian Electrical Code, Part II, see the preface of the latest issue of CSA Standard C22.2 No. 0, Definitions and General Requirements.
This Standard was prepared under the jurisdiction of the CSA Standards Steering Committee on CE Code, Part II, and was formally approved by this Committee.
Scope
1.1
This Standard provides test procedures for assessing the flammability properties of polymeric materials, used in electrical equipment in response to heat and flame under controlled laboratory conditions.
1.2
The test procedures listed in this Standard are provided in a recommendatory sense for referencing, in the Standards forming Part II of the Canadian Electrical Code. Although the verbal auxiliary shall is used to state the requirements of each test procedure given, it is essential to recognize that the procedures are nonmandatory in themselves unless mandated by individual Standards of Part II of the Canadian Electrical Code, in Standards of·other standards-writing organizations, or by users of this Standard.
1.3
Accompanying each test procedure is a series of observations, to be made and recorded, that are to be used when determining compliance with the criteria set forth in the individual Standards of Part n of the Canadian Electrical Code. This Standard provides procedures for making reproducible ,observations and serves as an aid in classifying materials.
