26、The package shall be clearly labelled and indicate manufacturer, product code, and batch number or manufacturing code. At the manufacturers discretion, additional information may be given according to ISO recommendations including filament diameter, roving or strand tex, strand length for chopped st

Traceability between the product delivered and manufacturing re

29、cords must be ensured. The strength retention of AR glassfibre shall be measured according to EN 14649. Users of AR glassfibre should require that manufacturers of AR glassfibre can show independent validation of the performance in the SIC test. 6 Compliance The glassfibre roving or chopped strands

30、shall be deemed to comply with the requirements of this standard provided that the conditions of clause 4 are fulfilled and the results obtained on test samples comply with the requirements of Table 1.
