CJ/T 157-2002Hotplate of lacquered toughened glass for gas appliance (English PDF)

Foreword

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

This standard is a revision of CJ/T 157-2002 "Coated Tempered Glass Panels for Domestic Gas Cookers," and CJ/T 157-2002.

The main technical changes are as follows.

--- Increased cold impact resistance requirements and test methods (see 5.9, 6.11);

--- Increased sharp edge testing (see 6.4);

--- Increased thickness deviation requirements (see 5.3.1);

--- Modify the state of debris requirements and test methods (see 5.8,6.10, 2002 version of 5.9,6.10);

--- Removed the temperature difference performance requirements and test methods (see 5.6, 6.9 in 2002 edition).

This standard is proposed by the Institute of Standardization of Housing and Urban-Rural Development Standards.

This standard is under the jurisdiction of the Gas Standardization Technical Committee of the Ministry of Housing and Urban-Rural Development.

1 Scope
