Foreword

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

This standard replaces JG/T 127-2007 "Building door and window hardware sliding support." Compared with JG/T 127-2007, the main technical content the changes are as follows.

--- Modify the scope of application;

--- Added terms and definitions (see Chapter 3);

--- Increasing the grading requirements for the opening and closing force of sliding supports for open top-hung windows (see 5.3.2.2);

--- Increased the operating requirements of the sliding support for the external casement window (see 5.3.3) and test methods (see 6.3.3);

--- Modified self-positioning force test method (see 6.3.1);

--- Modify the repeated opening and closing performance requirements (see 5.3.6) and test methods (see 6.3.6);

--- Increased anti-vandal performance requirements in the closed position [see 5.3.7 b)] and test methods [see 6.3.7 b)].

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

This standard is under the jurisdiction of the Standardization Technical Committee for Building Products and Components of the Ministry of Housing and Urban-Rural Development.
