Testing

SVV Praha, s.r.o. Centrum Lepení Brno (CLB) in Moravany u Brna offers the following tests and trials of bonded joints and substrates for proof of conformity with DIN 6701.

Destructive testing methods:

  • EN 1465 Adhesives – Determination of tensile lap-shear strength of bonded assemblies
  • EN 1464 Adhesives – Determination of peel resistance of adhesive bonds – Floating roller method
  • DIN 54457 resp. DVS1618 Structural adhesives – Testing of adhesively bonded joints – Bead peel test
  • DIN 53295 Testing of sandwiches; Peel test by means of a drum
  • EN ISO 13445 Adhesives – Determination of shear strength of adhesive bonds between rigid substrates by the block-shear method
  • DIN 54455 Testing of adhesives for metals and of bonded metal joints – Torsional shear test
  • DIN 53293 Testing of sandwiches; Bending test bending test in 3 or 4 points
  • EN ISO 11339 Adhesives – T-peel test for flexible-to-flexible bonded assemblies
  • EN 28510-1 Adhesives – Peel test for a flexible-bonded-to-rigid test specimen assembly – Part 1: 90° peel
  • ISO 10354 Adhesives-characterization of durability of structural-adhesive-bonded assemblies; wedge rupture test
  • EN 15336 Adhesives – Determination of the time to rupture of bonded joints under static load
  • Static tensile tests of polymeric and non-polymeric substrates
  • Tests evaluation according to ISO 10365 Adhesives; designation of the main failure patterns

Other testing methods:

  • Contact angle measurement and free surface energy determination – appliance  See System ADVEX INSTRUMENTS
  • Thickness measurement of polymeric and non-polymeric coatings – appliance  probes PosiTector
  • Hardness measurement of polymeric and metallic materials

Ageing tests:

According to e.g. EN ISO 9142 Adhesives – Guide to the selection of standard laboratory ageing conditions for testing bonded joints including the so-called „cataplasma“

Substrate surface preparation:

  • Preparation of surfaces before gluing by plasma with additional gases N2, Ar, O2, Plasma Slit 004 device
  • Preparation of surfaces before gluing using oxygen plasma Plasma Tigres ABC O2 device
  • Ultrasonic washing of the substrate surface

Other offered services:

  • Validation, verification testing, determining the suitability of machines and the gluing process, tests in series production
  • Custom test cycle design
  • Design of technology for the production of glued joints, including construction, validation and quality monitoring
  • Design and production of product prototypes by 3D printing

We will prepare an individual price offer of services for you.
