Under dry conditions, the specimens shall be subjected consecutively to four complete cycles of
temperatures, with each complete cycle consisting of the following steps in the following order:
a) –
40 ± 2 °C (– 40 ± 4 °F) for 20 min to 1 h;
b) 20
± 5 °C (68 ± 9 °F) for a minimum of 20 min;
c) 75
± 2 °C (167 ± 4 °F) for 20 min to 1 h; and
d) 20
± 5 °C (68 ± 9 °F) for a minimum of 20 min.
The temperatures specified in Items a) to d) shall be measured within 50 mm (2 in) of the centre of the
location of the specimens. Temperature ramping may be used for achieving the temperatures specified
in Items a) to d). For the steps specified in Items a) and c), the temperature ramping time (if any) plus
the time during which the specimen is at the specified temperature (a minimum of 20 min) shall not
exceed 1 h.
During testing, there shall be free circulation of air around the specimens and most of their surface area
shall not be in contact with other specimens or the holding container.
5.2.3.4 Organic coatings
The adhesion of organic coatings shall be tested in accordance with Method A of ASTM D3359. The
organic coating shall have an adhesion rating of 3A or better.
5.2.4 Decorative organic coatings
5.2.4.1 Performance requirements
In addition to complying with the adhesion testing specified in Clause 5.2.3.4, decorative organic
coatings shall show no surface defects when they are tested in accordance with Clauses 5.2.4.2 and
5.2.4.3, and their finish shall not erode in such a way that the surface directly beneath the organic
coating is exposed when they are tested in accordance with Clause 5.2.4.4.
5.2.4.2 Water degradation
Specimens shall be immersed in distilled water maintained at 38 ± 1 °C (100 ± 2 °F) for 24 ± 0.5 h in a
corrosion-proof container and then removed and examined.
5.2.4.3 Soap and cleaner effects
Two drops (0.10 mL total) of each of the following solutions shall be applied to the organic coating
(preferably on a flat surface) and allowed to remain there for 16 h:
a) ammonium
hydroxide (6N);
b) sodium
hydroxide (6N);
c) methanol
(100%); and
d) surfactant
(100% polyethylene oxyethanol).
At the end of the 16 h period, the excess liquid shall be removed by rinsing with water, and the coating
shall be dried and examined.
Note: Non-ionic surfactants complying with Item d) include GAF Igepal CO, GAF Igepal CA, and Shell Triton X-100.
5.2.4.4 Abrasion resistance
Specimens shall be tested in accordance with Method A of ASTM D968 using 12 L (3.2 gal) of silica sand
on a relatively flat surface of the specimen.
