For Laboratory testing and sample reporting procedures, refer to [[1056.1 Laboratory Testing Guidelines for Sec 1056|1056.1 Laboratory Testing Guidelines for Sec 1056]].


:(a) Appropriate sampling thief.
'''Procedure.''' Acceptance of tinting materials shall be based on verification of manufacturer’s certification that the tinting material complies with ASTM C979. A copy of the manufacturer’s certification shall be provided to the inspector by the supplier for acceptance purposes.
 
:(b) One-half in. (12 mm) sample splitter.
 
==Procedure==
 
Care shall be exercised in obtaining the sample because the material is subject to segregation. At least three bags should be selected and a sample obtained from each bag by use of an appropriate sampling thief. The sample shall be reduced to approximately one quart (1 liter) by use of a one in. (25 mm) sample splitter, taking care to eliminate loss of tinting compound during the splitting procedure. The sample shall be submitted to the Laboratory in a one quart (1 liter) friction top can accompanied by a properly completed Form T-617 showing the manufacturer's name, the brand name and designation of the material, lot number and net quantity represented.
