Product Testing

Product testing is carried out on both raw materials and final product.

All rubber compounds used in the production of our products are tested and validated in our laboratory prior to acceptance, and are batch coded to ensure full traceability.

Records of production and material tests are retained for a period of 10 years.

Every production batch of brake hose is tested to ensure that volumetric expansion, tensile and burst characteristics exceed international specifications.

Brake hose testing to SAE J1401 is carried out in our fully equipped laboratory every 6 months to ensure continuous compliance to international standards. These tests comprise: -
