Tyre Testing

As tyre is one of important industrial products, global tyre industry is on rapid development along with the boom of auto industry in the world. China, the global manufacturing center, is the largest country for tyre manufacture and export. However, there are more challenges for tyre businesses in China on export when awareness for environmental protection is constantly strengthened and regulations from various countries are issued, especially after Sino-US Tyre Special Safeguard Case.

 

PAHs Testing

8 PAHs of EU REACH

18 PAHs of GS Mark certification in Germany

16 PAHs of US EPA


PAHs

PAHs usually exist in petrochemical, rubber, plastics, lubricant, antirust oil and organic compounds of incomplete combustion. Partial PAHs remain in the products due to its application in manufacturing process such as that of plastics, dyes and pesticides. There may also be PAHs in rubber and plastic parts, as well as paint and coating of electricals & electronics, toys and childcare products.

REACHAnnex XVII has placed a restriction (refer to Table 1) on 8 PAHs in tyres, their spare parts, retreads,treads and extender oil. Products cannot be placed in the EU market if they fail to comply with the standards.

Standard

Products shall not be exported if sum of 8 PAHs exceeds the limit stipulated in REACH Annex XVII

1 mg/kg

Sum of 8 PAHs

10 mg/kg

In addition, there are different test methods for products in REACH Annex XVII:

  • IP 346:2004 is used for measurement of PAHs in extender oil, but it will go invalid according to the amendment of (EU) 2015/326;
  • EN 16143 will formally supersede IP 346 from 23 September 2016.
  • Nuclear magnetic resonance (NMR) method is applied to measure the content of PAHs in vulcanized rubber according to ISO 21461



Requirements of GS Mark Certification in Germany

In August 2014,the German Committee’ Technische Arbeitsmittel und Verbraucherprodukte (AtAV)’published new regulatory requirements on PAHs for GS Mark certification. The new standard AfPS GS 2014:01 PAK will replace the previous ZEK 01.4-08 since 1 July 2015.
