  • (1888PressRelease) January 28, 2022 - SGS, the world’s leading testing, inspection and certification company, is reminding footwear and footwear component manufacturers that ISO has updated its test method for determining polycyclic aromatic hydrocarbons (PAHs) in footwear materials.

    ISO 16190 defines a test method that requires a sample to be extracted using toluene in an ultrasonic bath. An aliquot is then analysed using a gas chromatograph with mass selective detector (GC-MS).

    There are several updates in the new version of the standard, including technical and/or editorial changes to:
    • Terms and definitions
    • Reagents
    • Apparatus
    • Sample preparation
    • Procedure
    • Expression of results

    PAHs are a group of structurally related hydrocarbons that have the characteristics of persisting in the environment and accumulating in food chains. They are known to be mutagenic, toxic, and/or carcinogenic to aquatic life and humans and, because of this, many major markets enforce restrictions on their presence in finished products.

    In clothing and footwear products, PAHs are usually only present as impurities from low-grade raw materials. They are not intentionally added. Raw materials that may contain PAHs include extender oils (for softening) and carbon black (reinforcing agent). In footwear, this meaning PAHs can often be found as impurities in outsoles and printing pastes for screen prints.

    Published in November 2021, ISO 16190:2021, “Footwear – Critical substances potentially present in footwear and footwear components – Test method to quantitatively determine polycyclic aromatic hydrocarbons (PAHs) in footwear materials” replaces the previous iteration of the standard from 2013.
