EXECUTIVEFatigue Test for Garment Accessories
Purpose: To test the function and durability of parts such as zips, fasteners, latches, and velcro with
repeated cycles of use to determine the longevity of a product as it is intended with normal regular use by
the customer. Method: Depending on the accessory being tested, the QC inspector fastens and unfas-
tens the item either manually or mechanically with a peel test machine or fatigue tester.
Fatigue Test on Your Quality Control Checklist: The details of the test are written on the quality control
checklist in a similar way to the pull test, specifying the number of samples to be tested and the number
of cycles. A typical fatigue test would require 50 cycles. If more is needed, it may be necessary to carry
out the fatigue test in a laboratory environment. Example of checkpoint instructions: Check the fasten-
ers (buttons, zippers, velcro etc.) for 50 cycles. Accessories must still be undamaged and still function
following the test.
Stretch Test for Elastic Fabric and Straps
Purpose: To test the capacity of elastic fabric used in garments such as swimwear, sportswear, and
lingerie, or accessories such as straps or waistbands to stretch, elongate and recover. Method: A straight-
forward and simple test: the inspector stretches the elastic by hand and checks for any damage to the
elastic fibers or loss of elasticity after stretching.
Stretch Test on your Quality Control Checklist: This type of test is usually carried out on a full general
inspection sample size, so ‘G’ is written in sample size/quantity column. Example of checkpoint in-
structions: Stretch the elastic fabrics and straps to check the elasticity. The fibers of stitches should not
break.
Buttonhole Test
Purpose: To check for stitching defects and ensure buttons stay securely fastened on garments as well
