Performance testing for rubbers, adhesives and coatings 

To validate certification requirements and demonstrate compliance to national and international product standards, Kiwa’s accredited and independent modern laboratory facilities offer mechanical, physical, mechanical and chemical testing on all rubbers, adhesives such as: 

  • Rubbers are tested also on requirements for hardness, tensile strength, elongation, and volume change.  
  • Adhesives’ performance tests strength measurements like tensile, shear and peel data and other adhesive property tests such as impact, odor, and aging.  

Some well known and typical tests voor these products are: 

  • EN 681-1:1996+A3:2005  Elastomeric seals – Materials requirements for pipe joint seals used in water and drainage applications – Part 1: Vulcanized rubber
  • ISO 34-2:2015  Determination of tear strength
  • ISO 37:2017   Determination of tensile stress - strain properties
  • ISO 48:2010  Determination of hardness
  • ISO 188:2011  Accelerated ageing or heat-resistance tests
  • ISO 813:2016  Determination of adhesion to a rigid substrate
  • ISO 815-1:2014  Determination of compression set, high temperatures
  • ISO 815-2:2014  Determination of compression set, low temperatures
  • ISO 1431-1:2012  Resistance to ozone cracking
  • ISO 2285:2013  Determination of tension set under constant elongation, and of tension set, elongation and creep under constant tensile load
  • ISO 3865:2005  Methods of test for staining in contact with organic material
