Standard 100 on the label, how to read the details

Short answer: Standard 100 on the label is a mark showing that a test institute has tested the textile for selected substances under fixed rules. You can read a number, an institute and often a product class on the label. Here is a plain guide to what the details say and what they do not.

What Standard 100 means on a label

Standard 100 refers to Oeko-Tex Standard 100, an independent label for textiles. It shows that the item, or parts of it, has been tested for selected substances that are unwanted in clothing. The label supplements other details such as material and care instructions, and it does not replace your own judgement of what suits you.

Number and institute

Next to the mark there is normally a number and the name of the institute that did the testing. When you look at the bamboo jogging sets for women and see the mark, note the number and look it up with the issuer if you want to be sure. It takes a few minutes and shows whether the information belongs to that exact item.

The product class

The mark can include a product class, which depends on how closely and in what way the textile is used. The closer to the skin, the stricter the requirements usually are. The class therefore says something about the test requirements, but nothing about quality, fit or durability in general.

What the label does not tell you

The label does not tell you how soft the garment feels, how it fits or how long it lasts. It also says nothing about how it was made apart from the tested substances. Use it as one piece of information among several, and read the material details, the size chart and the care label too before you decide.

Validity and date

An approval normally has a period of validity and must be renewed. That is why it is a good idea to check that the number is still valid when you look it up. If there is no number, or you cannot find it, ask for documentation before you give the mark any weight.

The whole item or only parts of it

The mark can apply to the whole item or only to some parts, for example the fabric itself. Read carefully what is covered, and do not assume everything on the item has been tested. If it is not clearly stated, it is reasonable to ask before you buy.

The label on sweatpants and T-shirts

The same reading applies to the rest of your clothes. Look at the label on bamboo sweatpants for women and on bamboo T-shirts for women, and compare number, institute and material. That gives you one consistent way to judge clothing, whether it is for home or for everyday wear.

The care label next to the mark

Always read the care label together with the mark. Wash by the instructions, choose a gentle programme at a moderate temperature and avoid harsh additives. Let the clothes dry flat or hanging, and avoid strong heat if the label advises against it. That way the fabric keeps its shape and softness for longer.
