Product information
All garments in H&M's collections go through a number of quality and security tests. Today we have our own laboratories in the biggest production offices, as well as in the main office in Stockholm, where the tests are performed. Before the goods are delivered to our stores they have been tested several times. Shrinkage, wringing, colour fastness and dryrubbing are examples of things that we check. Extra high demands are put on children's clothes where no sharp objects or flammable materials may occur. Here you can read more about the important tests and our work with securing the quality of our products.
Zipper test
Here we test the durability of the zipper.
Flammability tests
The flammability of the fabrics are tested using strict restriction limits.
Chemical tests
A number of tests are performed with special care taken to substances that can provoke skin irration, allergies or cancer.
Button test
With a special machine we control that the buttons on all baby and children's clothes are attached safely.
Measurement test
The seams and measure of the garment is controlled, both before and after washing.
Nickel test
Here we make sure that buttons, zippers, jewellery and other metal details do not contain nickel.
Read more about our nickel tests here.
Pilling test
The garment is tested to measure the appearance of pilling and abrasion.
PH-test
We make sure that the PH-value is neither too high nor too low. This is done to avoid skin irritation.
PVC-test
From January 1 2002 none of H&M's garments contain the plastic material polyvinyl chloride (PVC). Tests are performed to make sure this is followed.
Read more about our ban on PVC here.
Salt and chlorine-bleaching test
All swim wear are tested to make sure that their colours do not change or fade.
Washing test
Garments are tested to make sure that shrinkage, wringing and colour fastness are within H&M's limits. Washing tests are made several times during the production of the clothes.
