GB 4706.13-1998 Special requirements for safety of refrigerators, food freezers and ice machines for household and similar electrical appliances
Some standard content:
GB4706.13-1998 | | tt | Special Requirements for Ice Machines". The original GB4706.13-1991 "Special Requirements for the Safety of Household and Similar Electrical Appliances for Whole Household Refrigerators and Food Freezers" and other bureaus adopted IEC335-2-24:1984 and its Supplement 1 (1987). With the development of household refrigeration appliances, the varieties have increased, their performance has improved, and there are new safety requirements. The standard is no longer adaptable and needs to be revised. This standard replaces GB4706.13-1991 and adds safety requirements for ice machines. Since IEC335-2-24:1992 is used in conjunction with IEC335-1 "General Safety Requirements for Household and Similar Electrical Appliances", this standard should be used in conjunction with GB4706.11992. Changes in the latest version of the IEC standard and the corresponding national standard version in my country should be taken into account when using it. This standard is proposed and administered by the National Technical Committee for Standardization of Household Electrical Appliances. The main drafting unit of this standard: China Household Electrical Appliances Research Institute. The main drafters of this standard: Sun Longrong, Ma Dejun, Tong Junqing. GB4706.13-1998 | | tt | Expresses international consensus on the issues involved. 2) These resolutions or agreements are intended for international use in a recommendatory manner and are recognized by the National Committees in this sense. 3) In order to promote international unification, IEC expressed the hope that national committees should adopt the contents of IEC standards as their national standards as much as possible to the extent permitted by their domestic circumstances. If there are any differences between IEC standards and corresponding national standards, they should be clearly pointed out in the national standards as much as possible.
This part of the IEC335 series of standards was formulated by Subcommittee 61C "Household Refrigeration Appliances" of IEC Technical Committee 61 "Safety of Household and Similar Electrical Appliances". The third edition (IEC335-2-24:1992) cancels and replaces the second edition (IEC335-2-24:1984) and its Supplement 1 (1987). The contents of this standard are based on the following documents: Draft

All information regarding the voting of this standard can be found in the voting report shown in the table above. Appendix AA and Appendix BB are integrated with this standard. The third edition of IEC335-2-24 is to be used together with IEC335-1. IEC335-1 is based on the second edition (1976) and the second re-edition (1983) including Supplement 1 (1977), Supplement 2 (1979), Supplement 3 (1982) and Supplement 4 (1984), Based on Supplement 5 (1986) and Supplement 6 (1988). A new version or supplement to IEC335-1 is being considered. The second part supplements or modifies the corresponding provisions of IEC335-1 to make it IEC335-2-24 "Safety Requirements for Refrigerators, Food Freezers and Ice Makers" (Third Edition). If a special provision in Part -- is not mentioned in Part II, that provision may be used as a matter of course. If there are "additions", "modifications" or "replacements" specified in the third edition of IEC335-2-24, the corresponding requirements, test specifications or notes in Part 1 should be modified accordingly.
The following differences exist in some countries:
