Summary: This standard applies to electrical installations and equipment components Determination of burning plastic for flammability of plastic initially heralded apply to a specific usage scenarios. This standard describes test methods including the standard size of the sample, only for measurement and description of the equipment used in the materials under controlled laboratory conditions, the heat and flame combustion performance. Materials for heat and flame reaction is dependent on the actual size and shape of the sample and the use of the material of the end use product. This standard is not used to assess the final application of the other important features of the evaluation including (but not limited to) flammable, burning rate, flame spread, energy release, the intensity of combustion, combustion products and so on.

Foreword

This revised standard adopts UL94.2001 "is used as part of the instruments and equipment Plastics - Determination of burning." For ease of use, and this standard UL94.2001 compared to do the following editorial changes. --- Remove the UL standard "Preface" and "Introduction"; --- The standard Chapter 2, "Normative references" in the reference standard, the use of IEC (or ISO ) standard into the corresponding country Standards are replaced with national standards. With the technical content of this standard UL94. Differences 2001 are as follows. --- Remove the original UL94. in 2001, Chapter 13; --- Remove the original UL94. in 2001 Addendum A and Addendum B. The standard proposed by China Electrical Equipment Industrial Association. This standard by the National Standardization Technical Committee of the insulating material (SAC/TC51) centralized. This standard is mainly drafted by. Guilin Institute of Electrical Science. Drafters of this standard. Long in English. This standard was first formulated. Instruments and equipment parts with plastic combustion determination

1 Scope

1.1 standard applies to electrical installations and equipment parts with plastic burning determination to preliminary predict whether applicable flammability of plastics To a specific usage scenarios. 1.2 This standard describes the test methods, including a sample of standard size, only used to measure and describe the equipment used in the material, in controlled Under laboratory conditions, the heat of combustion and flame performance. Material for heat and flame of the actual reaction depends on the size and shape of the sample Shape and the use of the end use of the material product. The evaluation criteria can not be used to assess the final application Other important characteristics include (But not limited to) flammable, burning rate, flame spread, energy release, the intensity of combustion, combustion products and the like. Final Acceptance 1.3 material depending on the material used in the complete equipment, it shall comply with the relevant equipment standard, burning grade material Depending on the requirements included in the equipment and materials for a particular purpose, use of the material obtained by the method of standard performance level can not calculate it The relationship between the performance of the final application occasions. 1.4 This standard can be used to assess other non-metallic materials. 1.5 standard can not be used to assess the construction and decoration materials. 1.6 If the product contains a new or different from the development of this standard of existing features, characteristics, components, materials, or systems, and there is a fire, electric shock, personal The risk of injury, should adopt appropriate additional components and final product requirements for product evaluation, to ensure product safety of persons, of To the original intent of the development of this standard. Features, characteristics, components, materials, or systems conflict with the requirements of this standard should not be used or specified products This standard. Consistent with the recommended standards development, revision and implementation of the method requires revision.
