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.

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 =
