SN/T 3532.2-2016Technical requirements for the safety of household and similar electrical appliances for import and export--Part 2: Particular requirements for blankets, pads and similar flexible heating appliances (English PDF)

Foreword

SN/T 3532 "Safety Technical Requirements for Import and Export Household and Similar Electrical Appliances" is divided into three parts.

--- Part 1. General requirements;

--- Part 2. Special requirements for electric blankets, electric heating pads and similar flexible heating appliances;

--- Part 3. Electronic toilet.

This part is the second part of SN/T 3532.

This part is drafted in accordance with the rules given in GB/T 1.1-2009.

This section uses the redrafting method to modify the use of IEC 60335-2-17:2012 (version 3.0) "Safety of household and similar electrical appliances - 2 Part 17. Special requirements for electric blankets, electric heating pads, clothing and similar flexible heating appliances.

The main differences between this part and IEC 60335-2-17:2012 are as follows.

--- Increased the difference between AS/NZS60335.2.17.2012 (English version), J60335-2-17 (H20) (Japanese version) and IEC standard section.

--- Added Appendix DD and Appendix EE.

This part has been developed in consideration of the current and current version of the above standards, due to differences in national standard versions and IEC 60335-the 17.2006 difference is not treated as a national/regional difference.

This section also made the following editorial changes.

--- Remove the preface to the international standard IEC 60335-2-17:2012;

--- The appendix of the increase in the difference is numbered sequentially from DD, and the appendix number of the original standard is indicated in parentheses.

Introduction

It has been assumed in the drafting of this section that the provisions of this section are implemented by suitably qualified and experienced individuals.

This section recognizes internationally recognized equipment such as electricity when it is used normally under the conditions of the manufacturer's instructions.

Hazardous protection levels such as gas, machinery, heat, fire and radiation, it also includes abnormal conditions that can be expected in use, and consider electromagnetic the manner in which interference affects the safe operation of the appliance.

In the development of this section, the requirements of the electrical wiring rules specified by the major trading countries/regions have been considered as much as possible, such as.

Standards such as IEC 60364, GB 16895, etc., so that the appliance is harmonized with the requirements of the electrical wiring rules when connected to the grid.

If multiple functions of an appliance involve different standard requirements, the relevant standards should be applied separately as long as they are reasonable.

For each function. If applicable, consider the impact of one feature on other features.

An instrument conforming to the text of this part, when inspected and tested, found that other characteristics of the device would impair the requirements of this part of the and the level of safety will not necessarily determine that it meets the safety guidelines in this section.

When the product uses various materials or various structural forms other than those specified in the requirements of this section, the product may be used in accordance with this section.

The intent of these requirements is to be inspected and tested. If it is found to be substantially equivalent, it can be determined that it meets the requirements of this section.

This part consists of two parts. the IEC standard body and the country/region difference. The main part is composed of IEC 60335-2-17:2012;

AS/NZS60335.2.17.2012, EN60335-2-17:2013,J60335-2-17(H20), requirements for differences in relevant countries/regions and China's special national conditions constitute a difference.
