EN 4416:2006 (E) 10 4.2.3 Test samples Samples and associated test pieces shall be marked in such manner that their identity and orientation (where appropriate) with respect to the product and the batch is maintained in a traceable manner. Unless otherwise specified in the test procedure, all test samples or specimens cut from the test samples shall be freely exposed in an atmosphere of (65 ± 2) % r.h at a temperature of (20 ± 2) °C (EN 20139 standard temperate atmosphere for testing) for the following periods: products having a mass per unit area less than 240 g/m2 ≥ 6 hours other products ≥ 16 hours For products having a mass per unit area less than 240 g/m2 manufactured wholly or partly from natural fibre, testing shall be completed without removal from the conditioning atmosphere. For all other products, if the test samples or specimens are removed from the conditioning atmosphere for test purposes, testing shall be completed within 15 minutes of such removal and the temperature shall be maintained in a draught free environment. In the event of a dispute, all testing shall be completed in the conditioning atmosphere. 4.2.4 Storage life/shelf life Not applicable. 4.2.5 Shoplife/work life/pot life/application time/out time Not applicable. 5 Qualification 5.1 Introduction Qualification is not conducted as an independent exercise on textiles, but instead, with an item of equipment or sub-assembly fabricated from or incorporating the textile. Product qualification according to EN 9133 is therefore not applicable. In the event that a manufacturer is working for the first time either on a particular type of textile or to EN standards there shall be an increased frequency of sampling and testing until assurance of competence/ compliance is obtained (see 6.2). Provision is required for the testing of certain characteristics at the outset of new production and on an infrequent as opposed to a batch basi
