Decorated products
• Gloss test (EN ISO 2813)
The gloss must be measured for every lot of decorated products (one lot represents a
customer's complete order in one colour or that part of the order which is in the plant).
If the gloss cannot be measured with apparatus, a visual assessment must be carried out
The results of these analyses must be entered in some record (register) readily accessible
to the inspector, showing the nominal values and maximum values not to be exceeded.
• Coating thickness test (EN ISO 2360)
The coating thickness must be measured on at least as many samples as specified below:
Lot size
Number of samples
(random selection)
Acceptance limit for
rejected samples
1 – 10 All 0
11 – 200 10 1
201 – 300 15 1
301 – 500 20 2
501 – 800 30 3
801 – 1,300 40 3
1,301 – 3,200 55 4
3,201 – 8,000 75 6
8,001 – 22,000 115 8
22,001– 110,000 150 11
The results of these measurements (minimum and maximum values) must be entered and
retained on some record readily accessible to the inspector.
3.3.2.3 Pre‐curing and curing conditions
Pre‐curing and curing conditions must be monitored to ensure compliance with the supplier’s data
sheet by measuring the temperature at least once a day on one point of the section surface and at
least once a week at 3 different points in the oven to ensure uniform stoving.

‐ Inspection of decorated products
The inspector must perform the following tests on the decorated parts:
