scope:

This standard describes three test methods for measuring mounting forces for U-Channel glass run designs.

Method A: Run Channel Insertion Force is designed to determine the mounting force (insertion force) of a glass run channel into the U-channel.

Method B: Recovery Force is designed to determine the force required to compress a glass run channel to U-channel dimensions and to check for sufficient elasticity of the profile after the compression is removed.

Method C: Glass Insertion Force is designed to determine the forces required to insert a glass pane into a flocked or coated glass run channel upper section (header section).

Note: Nothing in this standard supersedes applicable laws and regulations.

Note: In the event of conflict between the English and domestic language, the English language shall take precedence.

Purpose. Not applicable.

Foreword. Not applicable.

Applicability. These test methods are applicable to all U-channel glass run designs.
