History of Ceramic Tile

Ceramics date back to antiquity, with clay figurines being contemporary to the cave paintings of Lascaux. Sometime later, ceramics were utilized for pottery. In fact, the origin of the word “ceramic” is the Greek keramos, meaning “of pottery.”

After humanity had grown more sedentary and civilization took hold, ceramic tiles emerged. Today, ceramic tile, much like the material’s purpose thousands of years ago, enhances the attractiveness of buildings and structures. And, for the past thirty years or so, ANSI A137.1 has guided the industry that creates and installs ceramic tile.

Ceramic Tile and ANSI A137.1

Ceramic tile is aesthetically driven, but the placement of these mosaic or simple tiles on walls, ceilings, and floors can conceal visual obstructions that ultimately do improve the R-value of buildings. Ceramics are not inherently water-resistant, even though ceramic tile is often utilized with this quality in mind. In fact, the waterproofness of ceramic tile derives from several treatment processes of the material, particularly glazing or firing. Ceramic tiles are available in an assortment of different types with varying characteristics, including glazed wall, mosaic, quarry, pressed floor, porcelain, and specialty tile.

Adherence to a document like ANSI A137.1:2017 grants trust and reliability for the materials on the market, providing assurance that ceramic tiles will perform as expected. For example, porcelain tile is defined, in accordance with ASTM C373, as ceramic tile that has a water absorption of 0.5% or less. The Certified Porcelain Tile logo placed on the packaging for tile meeting this stipulation is attainable with the help of the ANSI A137.1:2017 standard.

ANSI A137.1 Testing and Guidelines

ANSI A137.1:2017 serves as a reference standard for buyers and specifiers of standard and second grade ceramic tile, decorative tile, and specialty tile. In describing the available sizes and shapes of ceramic tile, as well as their physical properties, the basis for acceptance methods, marking and certification, and definitions, the American National Standard helps to guide producers in maintaining quality control while manufacturing ceramic tile.

Shapes, sizes, and grades of ceramic tiles are the primary categories for classification. Furthermore, ANSI A137.1:2017 sets forth five aesthetic classes—V0 (Very Uniform Appearance), V1 (Uniform Appearance), V2 (Slight Variation), V3 (Moderate Variation), and V4 (Substantial Variation). Several procedures exist for testing ceramic tile in the standard, such as that for establishing water absorption ranges.

  1. I recently installed 4×6 Wedi shower pan with a 42” long decorative drain. A distinctive “pop” sound appeared when you pressed your finger down in one particular part of pan near drain. Approximately 12” running parallel with drain in one spot only. Wedi wanted to cut a portion of pan out with subfloor attached for inspection/warranty. Due to double joists and the amount of PL Premiem subfloor adhesive used with screws it was easier to cut floor hoist out as well. (Yes, major structural damage) After assuring me Wedi would covet ALL EXSPENCES relating to the removal of floor, they later came back saying they would replace pan but not the structural components. Blamed it on installation error. The next two Wedi pans that shipped had the exact same popping noice in the exact same spot straight out of the box. They said just put it in, the sound should go away. I refused and removed all Wedi materials and went back to a concrete pan. Was I wrong for refusing to install floor tile over a foam Wedi floor pan when there was obvious movement of some kind. I am not allowed to cut into pan or it voids warranty. However, if you pushed on pan the popping sound was there every time in one particular place. My theory is movement makes noise, movement under tile will at some point compromise the tile and or grout joint?????? Any opinions

  2. hi i requiered practice the ANSI A137.1 in Latin America please when i can practice this test in America Latina.

  3. Hi, do you have local supplier on the Philippines which I can communicate regarding on our Project requirements? Needed ASAP. Thank you
