ANSI A108 Installation Standards

The ANSI A108 standard, published by the American National Standards Institute (ANSI) , is a voluntary standard that defines ceramic tile flooring as well as test methods and physical properties for ceramic tile flooring materials. This standard is intended to serve as a guide for the public, manufacturers, distributors, specifiers, architects, tile contractors, testing laboratories, and other businesses and professionals in the tile industry. Essentially, the existence of this standard does not prevent anyone, including those who adopt it, from producing, marketing, or using products, processes, or procedures that do not conform to this standard.

The ANSI A108 standard consists of the following sections under the main title of "Installation standards":

A108.01 General requirements: Other trade substrates and preparations
A108.1A Ceramic tile installation in wet set method with Portland cement mortar
A108.1B Installation of ceramic tiles on cured Portland cement mortar Installation with dry-hardened or latex-Portland cement mortar
A108.1C Contractor's option: Wet-set installation of ceramic tile with Portland cement mortar or ceramic tile installation on dry-set or Portland cement mortar cured with latex-Portland cement mortar
A108.02 General requirements: Materials, environment and labor
A108.4 Installation of ceramic tiles with organic adhesives or water-cleanable tile-setting epoxy adhesive
A108.5 Installation of ceramic tiles with dry-set Portland cement mortar or latex-Portland cement mortar
A108.6 Chemical-resistant, water-cleanable tile-plug and joint-filled ceramic tile flooring
A108.8 Installation of chemical resistant furan resin mortar and jointed ceramic tile
A108.9 Installation of ceramic tiles with modified epoxy emulsion mortar/grout
A108.10 Mortar installation in flooring work

For the purposes of this standard,

Only tiles recommended by the manufacturer in accordance with the climatic conditions of the region should be used outdoors.
Indoors, only the types of tiles recommended by the manufacturer as suitable for walls or floors (traffic areas) should be used.
Wet areas refer to tiled surfaces that are wet, saturated, or exposed to moisture or liquids, such as showers, tub enclosures, floors adjacent to curbless showers, laundries, saunas, steam rooms, swimming pools, or outdoor areas.
