This standard uses redrafted Law Amendment uses IEC 61242:1995 "Electrical accessories for household and similar use cable reel" and its 2008 revision 1 and 2015 revision 2.

This standard IEC 61242:1995 technical differences and the reasons are as follows.

--- According to China's geographical and climatic environment, the provisions of Chapter 1 cable reel applies to the ambient temperature is usually not more than 35 °C, but occasionally Use up to 40 °C place. IEC 61242:1995 The ambient temperature specified in this chapter is "usually not more than 25 °C, even Seoul will reach 35 °C. "

--- On the normative references, this section made a technical difference with the adjustment to adapt to China's technical conditions, adjust the situation Concentration reflected in the second chapter "Normative references", the specific adjustments are as follows.

- Replaced IEC 60884 (all parts) with modifications GB/T 2099 (all parts) adopting international standards;

- GB/T 2900.18-2008 replaced by IEC 60050-441:1984;

- Equivalent with the international standard GB/T 4207 instead of IEC 60112:2003;

- Equivalent to the use of international standards GB/T 4208-2008 instead of IEC 60529:1989;

- Replace IEC 60245 (all parts) with GB/T 5013 (all parts) equivalent to international standards;

- Replace IEC 60227 (all parts) with GB/T 5023 (all parts) equivalent to international standards;

- Equivalent with the international standard GB/T 5465.2-2008 instead of IEC 60417;

- Equivalent to the international standard GB/T 9799-2011 instead of ISO 2081:1986;

- Replaced ISO 2093:1986 with GB/T 12599-2002 modified to adopt international standards;

- Equivalent to the use of international standards GB/T 14536.10 instead of IEC 60730-2-9;

- Replace IEC 60999 (all parts) with GB/T 17464 equivalent to the international standard.

--- According to the situation of users in our country, retained GB/T 19637-2005 7.1 and paragraphs 2 and 3 on the use of safety Identification requirements.

--- According to the rated current of the plug and socket of our country, the minimum nominal cross-sectional area of the flexible cable in 11.1.1 is not less than 1.0mm2.

--- According to GB/T 2423.4 and China's specific environmental conditions, Chapter 16 provides moisture test temperature (40 ± 2) °C.

IEC 61242:1995 The provisions of this chapter damp box "air temperature should be maintained at any convenient value between 20 °C ~ 30 °C (t ± 1) ° C ".

This standard made the following editorial changes.

--- According to the relevant provisions of GB/T 1.1, in Chapter 1 "Scope" added "This standard specifies the domestic and similar use of cable reel the classification, logo, structure, electrical performance, mechanical properties and other technical requirements ";

--- Remove some of IEC 61242:1995 for other countries and regions of the Notes, such as 12.2,12.12,21.2 Note.

This standard proposed by the China Electrical Equipment Industry Association.

This standard by the National Electrical Accessories Standardization Technical Committee (SAC/TC67) centralized.

1 Scope

This standard specifies the classification of household and similar use cable reel, marking, structure, electrical performance, mechanical properties and other technical requirements.

This standard applies only for AC rated voltage exceeds 50V but does not exceed 250V (single-phase cable reel) or more than 50V but not exceeding 440V (all cable reels other than single phase), cable reels with a rated current not exceeding 16A. These cable rolls the disk is intended for indoor or outdoor use for domestic, commercial, light industrial or similar purposes where safety is required in normal use.

This standard does not apply.

--- installed in the appliance or lamp in the cable reel;

--- Connected to the appliance or lamp in the cable reel.

Note 1. The cable reel installed in the appliance is in accordance with GB 4706.1 and GB 4706.7.

Note 2. The cable reel installed in the light fixture is required to comply with GB 7000.1 and GB 7000.225.

Note 3. Cable reels attached to fixtures or fixtures are specifically designed for fixtures and fixtures. It should be fixed on the appliance or lamp, or with the appliance or lamps at the same time delivery, it does not need to be installed, it does not have a separate anti-shock protection shell. For example, a cable winder attached to a lantern the standard is GB 7000.208.

This standard can be used as a guide to install or connect the cable reel in the fixture or fixture.

Cable reels complying with the requirements of this standard shall be suitable for use in ambient temperatures generally not exceeding 40 ° C, but environments within a 24-hour period the average temperature can not exceed 35 °C, the lowest ambient (air) temperature not lower than -5 °C.

In some special occasions, cable reel may require special structure.
