EN71-1 Tension Clamp 19mm Diameter Disc Jaws For Toy And Cloth Test

Product information:

This clamp conforms to the standard requirements of EN71-1998 8.4.2.2 and ASTM F963 8.9.1.1.It is used with the pull and push dynamometer for the tension test of the fabric or plush material of the toys surface. There are two kinds of the dynamometer: the pointer one and the digital display one.
The diameter of the round handles of the clamp is 19mm.

Principle:

Use clamps with jaws to which discs with a diameter of 19 mm are affixed.
Remove any clothing supplied with the toy. Attach the clamps at the most onerous position of the casing (e.g. seam joint between the leg and body) not less than 30 mm apart and equidistant to the seam.
If there is insufficient material to fully attach the 19 mm disc jaws, the tension test below shall be performed on another appropriate part (e.g. a limb), instead of across the seam.
Gradually apply a force of (70 ± 2) N between the two clamps within a period of 5 s. Maintain the force for 10 s.
Apply the test to this area of casing or seam only once.
Determine whether it is possible to insert the front part of accessibility probe A (see Figure 21) under a force of 10 N or less.
