The inspection requirements specified in 6.2.5.2 and 6.2.5.3 are intended as a general guide, indicating the minimum acceptable quality for laminates. Cut-to-size panels and certain applications involving full-size sheets may call for special quality requirements which can be negotiated between supplier and purchaser. In such cases the following requirements may be used as a basis for agreement. It shall be noted that only a small percentage of sheets in a batch (the level to be agreed with the customer) shall contain defects of the minimum acceptable level.
The following surface defects are permissible:
一Dirt, spots, and similar surface defects.
The admissible size of such defects is based on a maximum contamination area equivalent to 1,0 mm2/m2 of laminate and is proportional to the sheet size under inspection.
The total admissible area of contamination may be concentrated in one spot or dispersed over an unlimited amount of smaller defects.
一Fibres, hairs, and scratches.
The admissible size of defects is based on a maximum contamination length equivalent to 10 mm/m2 of laminate and is proportional to the sheet size under inspection.
The total admissible length of contamination may be concentrated in one defect or dispersed over an unlimited amount of smaller defects.
The requirements for reaction to fire are determined by the fire regulations of the country in which the material is to be used. The reaction-to-fire of construction products is classified in accordance with various test methods specific to the individual nation where the material is installed. For applications other than construction, fire test methods and performance requirements may vary from one country to another, and at present it is not possible, with any test, to predict compliance with all national and other requirements. No fire performance test is therefore included in this specification, however Annex B gives examples of how high-pressure laminates relate to ASTM E84[6] and EN 13501-1[2] and some of the most common fire test scenarios.BS ISO 4586-3 pdf download.
