The ASTM C1766-15 (R2019) standard establishes the requirements for gypsum panel products that are factory-laminated. These products are designed for use on walls, ceilings, or partitions either as part of a sound control system or as gypsum stud or gypsum coreboard. The standard covers various aspects including materials and manufacture, physical properties, dimensions and tolerances, finish and appearance, sampling, inspection, rejection, certification, packaging, marking, shipping, handling, and storage.

The standard emphasizes the importance of the manufacturing process and the quality of the materials used. It specifies the physical properties that the factory-laminated gypsum panel products must meet, such as strength, flexural strength, and dimensional stability. It also provides guidelines for the dimensions and tolerances of the products to ensure they meet the required standards.

The standard addresses the visual aspects of the gypsum panel products, including the surface finish and appearance. It also outlines procedures for sampling, inspection, and rejection of non-conforming products. Additionally, it covers certification, packaging, marking, and transportation requirements to ensure safe handling and storage of the products.
