Antistatic load tester

GB/T328.25-2007

This part specifies the static load puncture test of asphalt and polymer roofing waterproofing membrane. The long-term static load on the coil is different from the mechanical stress of short-time dynamic load. This method represents the static type with a certain time. pressure.

Antistatic load tester is suitable for

Do not carry the load carefully, do not vibrate.

The static load resistance is tested in three parallel test pieces according to the specified method, and all three pass through the flexible roofing membrane or waterproof material without leakage at the required load.
