GB/T 23107-2020Household and similar electric blankets - Methods for measuring performance (English PDF)

Foreword

This Standard was drafted in accordance with the rules in GB/T 1.1-2009.

This Standard serves as a replacement of GB/T 23107-2008 Household and Similar

Electrical Blankets - Methods for Measuring Performance. In comparison with GB/T

23107-2008, the main technical changes are as follows:

---The scope "household and similar electric blankets, wraps and duvets" is added

(see Chapter 1);

---Normative references "GB 4706.8 Household and Similar Electrical Appliances

- Safety - Particular Requirements for Blankets, Pads and Similar Flexible

Heating Appliances" and "GB/T 35758-2017 Household Electrical Appliances -

Measurement of Standby Power" are added (see Chapter 2);

---The terms "wrap", "duvet", "blanket with non-uniform temperature", "blanket with

a high temperature zone" and "blanket with ambient temperature compensation"

are added; the term "multi-temperature electric blanket" is deleted (see Chapter

3);

---The classification by "heated area", "adjustment mode" and "mode of fixing

underblanket on the mattress" is added (see 4.3, 4.6 and 4.9);

---The method of dimensional measurement is modified (see 7.1.1 and 7.1.2; 7.1.1

and 7.1.2 of Version 2008);

---The requirements for "textile composition" are added (see 7.3);

---"Heating time" is modified into "heating time and energy consumption" (see

Chapter 9; Chapter 9 of Version 2008);

---The requirements for "controller settings" are added (see Chapter 12).

This Standard uses the re-drafting method in the modification and adoption of IEC

60299:2014 Household Electric Blankets - Methods for Measuring Performance.

In comparison with IEC 60299:2014, the technical differences and the causes for these

differences are as follows:

---In terms of Normative References, this Standard adjusts the technical

differences to adapt to the technical conditions of China. The adjustment is

intensively reflected in Chapter 2 "Normative References". See the specific

adjustments below:

 GB 4706.8, which equivalently adopts the international standard, is used

to replace IEC 60335-2-17:2012 (see Chapter 6);

Household and Similar Electric Blankets - Methods for

Measuring Performance

1 Scope
