The slider may be d20611 If a bias is found, either its cause must be found and corrected, or future test results must be adjusted in consideration of the known bias.

Apply a compression force at a rate-of-traverse of approximately 13 mm 1? In the case of the entering type bottom stop, position the slider at the point where normally checked in its free movement.

Apply an initial load of 4.

Key Testing Facilities

As a minimum, the test samples should be used that are as homogeneous as possible, that are drawn from the material from which the disparate test results were obtained, and that are randomly assigned in equal numbers to each laboratory for testing.

This surface scanning method will not cause any damage. Compliance Checklist for Garments Factory. The salt spraying tester is used for testing the corrosion resistance performance of the metal zippers and electroplated sliders.

In addition the amount of permanent twist imparted to the slider pull or other permanent damage or deformation may be noted. Place the pull in the normal? The element to be tested is the one just below the element that was removed. Secure the zipper in the lower clamp of the testing machine as illustrated in Fig.

Force range of 5 kN to kN 1, lbf tolbf Adjustable test space The most popular choice for static tension and compression sstm These dual column testers are available in both tabletop and floor standing models. To measure force strength of zipper, test items: Current edition approved Jan.

The test methods appear as follows: The lower platen shall have attached to its entire surface a piece of neoprene rubber 6 mm 1? With beam displacement limit protection, force overload protection, voltage overload protection, overheating protection 8. The zipper reciprocating testing instrument is used for testing the anti-fatigue performance of the zippers through the reciprocating opening and closing of the zipper sample under the vertical and lateral tension.

Chain crosswise strength Element pull-off Element slippage, lengthwise Holding strength of stops: Apply an initial load of 1 lb and set the dial to zero. The components of variance expressed as coefficients of variation, calculated as percentage of the average were: Record any reading above zero as the amount of permanent set. Consider individual containers from each shipping carton to be the primary sampling units. The gas chromatography mass spectrometry instrument is used for the rapid detection of organic compounds in such raw materials as the toner, color paste, plastic particles, paint, etc.
