This standard is developed in accordance with the rules given in GB/T 1.1-2009.
This standard replaces QB/T 1560-2006 Accessories of bathroom.
In addition to a number of editorial changes, the following technical changes have been made with respect to QB/T 1560-2006:
——such products as soap dispenser, electric hair dryer holder, retractable clothesline, electric towel rack, toothbrush cup holder and commodity shelf are added and corresponding requirements and test methods for them are specified, making the standard more comprehensive;
——the time of acetic acid salt spray test is modified and the requirement for anti-corrosion of product is improved.
This standard was proposed by the China National Light Industry Council.
This standard is under the jurisdiction of the Subcommittee on Building Hardware of National Technical Committee on Building Hardware Standardization Administration of China (SAC/TC 174/SC 3).
The previous editions of this standard are as follows:
——QB/T 1560-2006;
——QB/T 1560-1992.
