Zipper reciprocating pull testing machine experimental test standards and requirements

The zipper reciprocating fatigue tester is used to test whether the zipper can withstand a specified number of reciprocating pulling operations under the action of transverse and longitudinal tension. During the test, the machine drives the slider of the zipper at a constant speed, and reciprocates 30 times per minute until the specified number of times. This article (Hong Kong) Co., Ltd. focuses on the introduction of the zipper reciprocating fatigue test standards and requirements for you. Standard requirements: 1, zipper strength test Zipperstrength: ASTMD2061/BS3084/AS2332/NFG91-005/DIN3419-12, zipper durability test DurabilityofZipper: BS3084/AS23323, color fastness test Colourfastnessto: Dry cleaning: BS1006: D01 Washing: BS1006: C03 Water: BS1006: E014, Shrinkage Test DimensionalStabilityto: Water Washing: BS20577: 2A Dry Cleaning: CommercialProcess5, Appearance Retention: Water Washing BS20577: 2A Dry Cleaning: CommercialProcess6, Metal Antirust and Corrosion Test Rust/TarnishTestofMetallicFinishes7, zipper torque test TorqueTestforZipperPuller : ASTMD20618, zipper insertion test ZipperInsertion9, zipper smoothness (usability) test OerabilityofZipper:ASTMD2062 conductedwithZipperStrength to measure the basic test method of zipper strength The ability to resist lateral forces in an interlocked state, which is very similar to actual use. (2) Test the upper stop strength of the zipper teeth interlock, pull the slider to the upper end stop, and pull the slider. At this time, the upper stop strength of the zipper can be measured, which simulates that the zipper is in the holding state. The ability of the slider to resist external forces when pulling off the upper stop or moving the upper stop from the rib. (3) The zipper test of the bottom stop strength Pull the slider to the lower end stop, the pull teeth are divided into left and right parts, pulling the left and right sides of the chain teeth can measure the force required for the bottom stop to be damaged, and measure the pull Resistance of head internals. (4) Test of open-end flat pull strength Test the open-end zipper cannula and socket to resist external force damage, fix the left and right sides of the open-end up and down with the clamp, and start the machine when the zipper is closed. (5) Test the locking strength of the slider. The slider is self-locked in the middle of the connecting teeth, and the zipper teeth are divided into two parts. The zipper of the left and right parts can be stretched to test the locking strength and the resistance of the internal components of the slider. force. (6) Test of the binding strength of the slider and the slider. Apply the slider force in the direction perpendicular to the slider until the slider is separated from the slider. The value recorded at this time is the binding strength of the slider and the slider. More about Zipper Reciprocating Fatigue Tester: http://www.lalianniukou.com/productlist/list-5-1.html
