Which standard is referenced for cement board installation in the material?

• A. ANSI A108 & A118
• B. IBC 505.2
• C. OSHA 1926.302(e)(1)
• D. IRC R603.2

Answer: (A)

The key idea is recognizing which standards govern how tile is installed and what materials are used with cement backer boards. Cement boards serve as the substrate for tile, so the cited references are the tile‑installation standards. ANSI A108 covers the overall process of installing ceramic tile, including how substrates like cement boards are prepared and fastened, while ANSI A118 covers the mortars and adhesives used to set the tile on those substrates. Together, they specify the proper installation methods and materials for cement board applications. The other options are building codes or safety standards, not the specific tile installation references for cement boards.
