1 This part 1 of EN 12971 establishes a method of designation for chopped strands made from continuous filament textile glass strands, which may be used as the basis for specifications.
2 This designation system is for chopped strands used for the reinforcement of plastics and the manufacture of synthetic bonded non-woven materials.
It does not apply to chopped strands made from staple fibres.
3 It is not intended to imply that chopped strands having the same designation give necessarily the same performance. Nor is the designation system intended to cover all the characteristics of chopped strands. This part 1 of EN 12971 does not give engineering data, performance data or data which may be required to specify chopped strands for a particular application or method of processing.
If such additional properties are required they should be determined in accordance with the test methods specified in EN 12971-2.
