4.2.1 Systems qualification. Manufacturers shall qualify total nonskid systems consisting of a primer, optional underlayment (class 4), nonskid, and color topping.

4.2.2 Extension of qualification. Approval of qualification for a color for all individual coatings of the nonskid system, excluding the color topping, shall constitute approval for other colors of the same type, composition, class, grade, and application. The manufacturers shall validate that all colors shall satisfy the requirements of 3.2.2, 3.2.3, 3.2.4, 3.2.5, and 3.13 by either analytical testing or documentation. Testing and qualification of one color variant of a color topping shall be automatically extended to all other colors for the same product within a particular gloss category, provided that the only difference in the product formulations is in the color pigment concentrations. Nonskid systems submitted for type V or VI qualification testing that do not pass the durability requirements for type V or VI, but do pass the durability requirements for type I or II, may be qualified as type I or II nonskid systems respectively, of the same composition, class, grade, and application provided that the system passes all other requirements for that type, composition, class, grade, and application. Products qualified to type V or VI are inherently qualified as type I or II nonskid systems, respectively. Products qualified to composition D are inherently extended qualification approval status to composition G.

4.2.3 General inspection. The coating system’s identification characteristics shall be reviewed to ensure conformance to the requirements specified in 3.3.

4.3 Conformance inspection. Conformance inspection shall consist of the conformance tests specified in table IX. At a minimum, conformance inspection shall be performed on the first lot and every 5,000 gallons

(19,000 liters) thereafter. For the purpose of conformance inspection, a lot shall consist of an individual nonskid system coating of the same type, composition, class, grade, and application from a single, uniform batch or a uniform blend of batches offered for delivery at one time. Conformance testing of the first lot and every

5,000 gallons (19,000 liters) thereafter of color topping shall be determined by the cumulative, total volumes of all colors of color topping produced by the manufacturer. Conformance testing is required on only one color of color topping. Color topping conformance inspections shall be conducted on any lot of white or yellow color topping.

4.4 Preparation for testing.

4.4.1 Standard conditions. Unless otherwise specified herein, standard conditions shall conform to

ASTM D3924, except that the temperature shall be 75±5 °F (24±2 °C) and the relative humidity shall be less than

85 percent.
