Which statement is true about veneer plaster lath?

Which statement is true about veneer plaster lath?

• A. It must conform to ASTM specification except dimensions of thickness, width and length do not apply
• B. It does not need to conform to ASTM specification
• C. It must conform to ASTM, including exact thickness, width, length
• D. It must be steel

Answer: (A)

Veneer plaster lath is covered by ASTM standards to ensure it will properly support plaster and perform over time. The standard focuses on how the lath behaves—its material properties, fastening, bonding ability, corrosion resistance, and compatibility with plaster—rather than mandating exact sheet sizes. That means the product must meet ASTM specifications for performance, but the exact thickness, width, and length aren’t fixed numbers that all products must rigidly match; there are legitimate variations in those dimensions as long as the material complies with the performance requirements. So the statement that it must conform to ASTM specification except for the dimensions is the best fit because it captures that emphasis on performance while acknowledging that dimensional ranges can vary in practice. The other options are not correct because ASTM compliance isn’t optional, exact fixed dimensions aren’t universally required by the standard, and veneer plaster lath isn’t restricted to steel alone (the key is meeting ASTM performance criteria, not a single material type).
