BS/ISO 4586-6-2015 pdf free.High-pressure decorative laminates (HPL, HPDL) – Sheets based on thermosetting resins (Usually called Laminates) – Part 6: Classification and specifications for exterior-grade compact laminates of thickness 2 mm and greater.
5 Requirements
5.1 Compliance
Exterior-grade Compact laminate types EGS, EGF, EDS and EDF shall meet all appropriate requirements specified in Clauses 5.2. 5.,3 and 5A. This applies to both full-size sheets and cut-to-size panels.
5.2 Inspection requirements
5.2.1 General
Inspection shall be carried out in accordance with ISO 4586-2, Test Method 4 at a distance of 1,5 m.
5.2.2 Colour and pattern
When inspected in daylight or D65 standard illuminant and again under tungsten illuminant F, there shall be no significant difference between the corresponding colour reference sample held by the supplier and the specimen under test.
NOTE Where colour and surface finish are critical, it is recommended that sheets be checked for colour and surface finish compatibility before fabrication or installation.
5.2.3 Surface finish
When inspected at different viewing angles, there shall be no significant difference between the corresponding surface-finish reference sample held by the supplier and the specimen under test.
NOTE Where colour and surface finish are critical, it is recommended that sheets be checked for colour and surface finish compatibility before fabrication or installation.
5.2.4 Visual inspection
5.2.4.1 General
The following inspection requirements are intended as a general guide, indicating the minimum acceptable quality for each decorative face of a laminate supplied as a full-size sheet.
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 should be noted that only a small percentage of sheets in a batch (the level to be agreed with the customer) should contain defects of the minimum acceptable level.
It may be agreed between purchaser and supplier that the visual quality standard applies to one decorative face only.
5.2.4.2 Surface quality
The following surface defects are permissible:
Dirt, spots and similar surface defects
The admissible size of such defects is based on a maximum contamination area equivalent to 2,0 mm2 / rn2 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.
Fibres, hairs and scratches
The admissible size of defects is based on a maximum contamination length equivalent to 20 mm/rn2 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.
5.2.4.3 Edge quality
Edge chipping up to 3 mm on each side is permissible.
5.3 Dimensional tolerance requirements
Dimensional tolerance requirements are specified in Table 2.BS/ISO 4586-6 pdf download.
