Section 3-2 Non-slip Paints
311. Application
The requirements in this Section apply to tests paints in accordance with the requirements of Pt
and inspections for the type approval of non-slip
7, Annex 7-3, 7 of the Guidance.
312. Data to be submitted
The reference data in addition to those specified in 102. are to be submitted to the Society in ac- cordance with 302.. The tests are to be made by using specimens of the final product.
313. Type tests
1. Test coupons
Three each test coupons for each test item specified in Table 3.3.3 are to be prepared.
2. Test details and acceptance criteria
Sampling of the precise amounts and test as follows should be done for each type of manufacture
in the presence of Surveyor. Also, other tests may be added at the discretion
(1) Physical properties test
Tests are to comply with the requirements given in Table 3.3.3.
of the Society.
Table 3.3.3 Test details and acceptance criteria of Physical properties test
Test item | Testing procedures | Acceptance criteria |
Cross-cut adhesion test | To be in compliance with Table 3.3.1. However, remove sand additives and paint with the thickness on the maker's advice. | To be in compliance with Table 3.3.1. |
Erichsen test | To be in compliance with Table 3.3.1. | Acceptance criteria is the reference. |
Falling ball impact test | To be in compliance with Table 3.3.1. However, thickness of sample to be 6mm and weight to be 1kg. | To be in compliance with Table 3.3.1. |
Flex cracking test | To be in compliance with Table 3.3.1. | Acceptance criteria is the reference. |
Abrasion test | To be in compliance with ASTM D 4060.(1) However, 3 samples are to be taken for an average. | Within 40% abrasion |
Notes; (1) To be based on resilient calibrase wheels No. CS-17, 1000 cycles, 1kg load given in ASTM D 4060. But the others for consideration of paints to be determined on a case-by-case basis upon mutual consultation by the manufacturer and the Society. |
(2) Friction test
(A) 3 samples are to be prepared from worn part of the abrasion test finished samples. Friction test procedure is in accordance with Test Method B(Horizontal Pull test) of ASTM D 4518.
The rubber plate has Shore-A hardness 60~70 is to be adhered to the surface of sliding steel plate. However, other test procedure may be applied at the discretion of the Society.
(B) An average of 5 times on friction test is to be taken from each condition(Dried condition, Wet condition with Synthetic Sea Water according to ASTM D 1141, Oily condition with Engine Oil). Also coefficient of friction is given by the following formula.
Coefficient of friction =
Load when sliding steel plate start to move Weight of sliding steel plate
(C) Average coefficient friction value of 3 samples is not to be less than those obtained by the following formula. Also each coefficient friction value is not to be less than 0.7.
Section | Dry Condition | Wet Condition | Oily Condition |
Acceptance Criteria | 0.9 | 0.85 | 0.75 |
(3) Corrosion resistance test
Saline water spray test and gasoline deposition test are carried out for corrosion resistance test. Also, test procedure and acceptance criteria are to comply with 303. 2. However, the test time is to be 360 hours.
(4) Non-flammability test
The procedure and acceptance criteria of the non-flammability test are to comply with 2604. 3.
