During an inspection, a battery of on-site tests are = performed in=20 order to check the conformity, functionality and usability of a product. = Some=20 tests are more or less reliable as other factors can influence the = result of the=20 test within the time. An inspection limitation for glued products is = regularly=20 observed. The reasons and solutions are detailed in this = article.
The on-site test for glued products is usually related = to the=20 abuse test. This means that the QC inspector will put the product into = the=20 condition of an =E2=80=9Cangry=E2=80=9D customer, using with force and = sometimes violence on the=20 product on a special level sample size based on the AQL table.
When performing an inspection, the products have been freshly = manufactured=20 therefore the glue is usually at its top level of efficiency. This means = that=20 the abuse test can pass quite easily as far as the supplier as well = glued the=20 product in the right areas.
However, with the time, the quality of the glue can show weaknesses. = If the=20 supplier uses a low quality glue or an inappropriate one (for instance = the=20 supplier uses a glue for leather to stick two papers, or uses a glue for = paper=20 to stick silicone and metal parts together) the defect may not appear = just after=20 the inspection but will appear later on.
The only way to make sure a glued product will last long enough is to = make a=20 life test in a laboratory. The common standard, used for shoes in = general=20 is EN12749 which tests the humidity aging 70?/ 100%RH for 7 working = days=20 approximately. The price of such test is estimated to 25USD/day This = test=20 simulates time conditions, i.e. 1 month, to see if the product is still = well=20 glued afterwards.
Only a laboratory can verify if a glue will glue well after some=20 time.
And=20 you: did you ever = experience glue=20 quality issues after receiving your goods?
