ČSN EN 3675 This document specifies the sampling plan for acceptance testing of aramid, carbon fibre and textile glass filament yarns in terms of sample size and rejection criteria. This document serves as a basis for the corresponding technical specification. It covers the inspection by attributes. The inspection by measurements (variables) will be added in subsequent edition. It is also planned to extend its scope of application to reinforcing woven fabrics.

ČSN EN 302-7 This document specifies a method for determining the working life for adhesives mixed with hardener for load-bearing timber structures, by a viscosity test. This method does not apply to determining the working life of a multi-component adhesive whose actual working life is very short. This document is only intended for obtaining a reliable basis for comparison between adhesives. The method gives results which cannot be applied to the safe manufacture of timber structures without modifications for the influences of factory temperature and relative air humidity.
