GESTER GT-KC10A Bally Resistance Flexing Tester has A, B two types grips, and the difference lies in the upper grips.
A Type grip is complied with below standard:
SATRA TM 55;IULTCS/IUP 20-1; ISO 17694 ; EN 13512 ;EN 344-1 section 5.13.1.3 and annex C;EN ISO 20344 section 6.6.2.8;GB/T20991 section 6.6.2.8;AS/NZS 2210.2 section 6.6.2.8;JIS-K6545.
Bally Leather Flexing Tester B Type grip is complied with below standard:
ISO 32100 ; DIN53351; ISO 5402-1;GE-24;ASTM D 6182.
Since the two clamps are suitable for many standards, the same basic dimensions and different tolerances are taken with smaller tolerances, which are regarded as the same standard.
The main difference between two grips is as below:
As figures showed, fig.1 for A Type Upper Grip,fig 2 for B Type Upper Grip
Both upper clamps consist of two plates, one for ABCFD and one for EGHCF. The main differences between the two upper clamps are:
1.The thickness for A type baffle ADFE is 4mm.
While the thickness for B type grips baffle ABCFD, EGHCF is 4±0.2mm, and baffle L(ADFE) can be added to 8mm regarding the test sample.
2.The horizontal length and vertical height for A type upper clamp ramp CD are both 25mm ( D is the intersection for CF and AD extension).
The horizontal height difference between the B type upper clamp surface BC and EF is 22.5±1 mm, and the horizontal distance from the hole core to the acute angle angle F is 23.2±0.2 mm, and the diameter of the hole K is required to be ∮50.0±0.5 mm.
3. The angle between the DF and CF of the A type upper clamp is a radius of 2 mm.
B type upper clamp DF is: a plane that is 150 degrees obliquely upward (∠ADF=150°) with the lower surface AD. The plane DF and the inclined plane CF are arcs with a radius of 2 mm.
