It is this increased long-term risk of causing cancers that has justified the introduction of this new European-wide legislation.
Protective gloves are typically made by dipping a former into a bath of latex containing a specific type of rubber, such as nitrile rubber NR or polychloroprene rubber CR , or can be a knitted glove with a dipped palm coating.
Elastics from adjusting straps that might be used in helmets and body protectors, and foams used in chin straps and shinguards are more examples of instances where the rubbers and plastics must conform to the PAH regulation. As previously mentioned, PAHs can be formed through the burning of fossil fuels and carbon black can also be manufactured in a similar way by the partial combustion of oil or natural gas.
Black rubbers and plastics generally contain carbon black as a pigment, so they are therefore more likely to contain PAHs than other colours. However, all rubbers and plastics may contain processing oils, plasticiser oils or extender oils which are added to modify and cheapen processing or plasticiser oils , regardless of their colour. These may also be manufactured from coal, crude oil or petrol and could contain PAH impurities. SATRA has developed an internal testing procedure to identify and quantify PAHs in rubbers and plastics, and this procedure is based on two published standards.
The principle of the SATRA procedure is that the test specimens are extracted with toluene at elevated temperature in an ultrasonic bath. Once the extraction is completed, the toluene containing the PAHs is filtered to remove any particulate matter and the resulting extract is analysed by Gas Chromatography with Mass Spectrometry GC-MS , shown in figure 2. This separates, identifies and quantifies any of the eight PAHs indicated in table 1, which may be present in the test specimen. Please contact chemistry satra.

However, this should be addressed during the next factory inspection. For the new issuance of secondary certificates and its related main-certificate, new PAH requirements must be complied before the next factory inspection, but not later than 28th December November, Relevant for: Significant changes of new PAHs requirements: Update the limit of PAHs: Amend the scope of categories 2 and 3: Category 2 newly includes materials with repeated short term skin contact.
Categories 2 and 3 are divided into two groups:
Comparing with existing ZEK , major changes are limits and categories. Please refer to the below summary and Table A for limits. The new PAHs requirements are mandatory for GS-Certification from 1 st July and the document ZEK will be invalid from 30 th June Many translated example sentences containing "Zek " – English-German dictionary and search engine for English translations. Mandatory application on the PAH document ZEK from 1 st July, onwards (exception: see ). GS mark certificates, issued before 1st July, For the time being, existing GS mark certificates remain valid.
