Stauff clamp bodies made of SAV0, a thermoplastic elastomer with V0 classified fire-protection capabilities according to the UL 94 plastics flammability standard released by Underwriters Laboratories, have been successfully tested in the Test Center for Railway Transport Vehicles in the Russian Federation.
The testing procedures included the inspection of clamping / holding forces of SAV0 clamp bodies of the Standard Series according to DIN 3015 - properly assembled with metal mounting hardware such as elongated weld plates, hexagon head bolts and cover plates - under the influence of mechanical and climatic factors. These were namely the exposure to vibration at regular and extreme ambient temperatures down to minus 55 degrees Celsius. All tests were performed according to GOST state standards 15150-69 and 30631-99.
In conclusion, no sliding or movement of pipelines related to their original position could be observed, and the clamp bodies maintained their full elasticity, which is an important contribution to efficient noise reduction and vibration damping in industrial applications.
The test results above have provided Stauff with the final technical approval to supply SAV0 clamp bodies and metal mounting hardware for projects of Russian Railways (RŽD).
