ASTM D7307-06(2016)

Standard Practice for Sampling of Thermoplastic Traffic Marking Materials

SIGNIFICANCE AND USE
5.1 It is important to obtain a truly representative sample of the thermoplastic traffic marking material prior to performing any tests. This can be difficult due to the wide ranges of sizes, shapes, and densities of the individual components that are used in the manufacture of these types of materials. The sample that is obtained using this guide should be representative of the manufactured lot from which it was obtained and can be used for the testing of the chemical and physical properties of the material as required by the governing specification.
SCOPE
1.1 This practice covers the proper field sampling of thermoplastic traffic marking materials to ensure test results are representative of the material being tested.  
1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.  
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

7. Hazards
7.1 Consult the material safety data sheet for the material being tested and follow the recommendations for the handling of the
material. Minimum safety equipment should be safety glasses, dust mask for nuisance dust, and gloves.
7.2 Use proper lifting techniques when handling the containers of thermoplastic traffic marking materials.
8. Procedure
8.1 Quartering Method:
8.1.1 Randomly select three bags of thermoplastic traffic marking material from the lot that is to be sampled. The lot size should
not exceed 18 662 kg (50 000 lb).
8.1.2 Place the section of cardboard, plywood, or metal on a level floor surface.
8.1.3 Empty the contents of one of the bags onto the sampling area. Using the metal scoop mix the material, breaking up any
large lumps. Shape the pile of material into as high of pile as possible forming a symmetrical inverted cone.
