NOTES:
1/
Manufacturing range percentages having variations of more than ±3%, without supporting documentation,
will be rejected and can cause delay or rejection of qualification. When specified (see 6.2), manufacturers
will provide documentation for any identification characteristics deemed non-applicable (i.e., drytime for a
tie-coat designed to be overcoated before completely drying). Also, should a test method not be applicable
for the product, the manufacturer will record the data and the alternative test method used.
2/
Antifouling topcoats only.
3/
VOC shall be determined in accordance with 4.4.3.
4/
Determine in accordance with 4.4.8.
5/
Certify in accordance with 3.3.5.2.
6/
Value as determined by manufacturer.
3.4 Qualitative requirements. See table IV for required tests.
3.4.1 Color. Colors of the individual paints of the paint systems shall:
a. Be as reported by vendor as an identification characteristic for that paint, when tested in accordance with
4.4.8.1, for the colors of the individual anticorrosive and tie-coat paints, except R0 color paints.
