independent testing laboratory containing a list of dimensional, chemical, metallurgical, electrical, physical, and other required test resul ts of the specified material certifying that the product or assembly has passed all specified tests. Include the following:
1.the project name and number
2.the manufacturer's name
3.the name of the product or assembly
4.a complete description of the material
5.count ry of origin
6.the lot, heat, or batch number that identifies the material
7.all required test results for the specified material from the same lot, heat, or batch defined in Subsection 722- 2.02.6
8.a statement, signed by a person having legal authority to act f or the manufacturer or the independent testing laboratory, that the test results show that the product or assembly to be incorporated into the project has been sampled and tested and the samples have passed all specified tests. Tag, stencil, stamp, or othe rwise mark all materials or assemblies furnished under certification to the project with the lot number, heat number, batch number, or other appropriate identification, which can be readily recognized and legible, and is identical to the accompanying certi fied test report. 515 ALASKA 2020 SECTION 72 3 WATERSTOPS
