PHYSICAL TESTING OF RUBBER - METHOD FOR DETERMINATION OF STRESS RELAXATION IN COMPRESSION AT AMBIENT AND ELEVATED TEMPERATURES
出版：British Standards Institution
专家解读视频
Gives three methods for determining the decrease in counterforce exerted by a test piece of vulcanized or thermoplastic rubber which has been compressed to a constant deformation and maintained thus at a predetermined test temperature. The use of ring test pieces is suitable for the determination of stress relaxation in liquid environments. Testing at temperatures below standard temperature is not specified. The methods have been used for low-temperature testing, but their reliability under these conditions is not proven. Covers normative reference, definition, principle, apparatus, test piece, duration, temperature and test liquid, procedure, expression of results and test report.
