ASTM C67

Standard Test Methods for Sampling and Testing Brick and Structural Clay Tile

A minimum of five full size brick or tile units per type/brand is suggested by ASTM for determination of modulus of rupture, compressive strength, absorption, and saturation coefficient.

ASTM C279

Standard Specification for Chemical-Resistant Masonry Units

Granular specimens are boiled in a sulfuric acid solution for a specified time period. The percent weight loss for two representative specimens per type/brand is determined.

ASTM C373

Standard Test Method for Water Absorption, Bulk Density, Apparent Porosity, and Apparent Specific Gravity of Fired Whiteware Products

The water absorption, bulk density, apparent porosity, and apparent specific gravity are determined by the boiling method. Testing of five unglazed specimens (of at least 50 gm/piece) is suggested by ASTM.

ASTM C554

Standard Test Method for Crazing Resistance of Fired Glazed Ceramic Whitewares by a Thermal Shock Method

The resistance to crazing of fired glazed whitewares is determined when subjected to thermal stresses. Specimens are initially heated at 250°F and water quenched. This cycle is repeated three times. If crazing does not take place, then the three cycles are repeated in 25°F increments up to 450°F. Failure is defined as the temperature at which crazing is observed. Testing of five specimens is suggested by ASTM.

ASTM C674

Standard Test Methods for Flexural Properties of Ceramic Whiteware Materials

Flexural strength is determined in three-point bending on bars of circular or rectangular cross-section. Testing of ten specimens per type/brand is recommended by ASTM.

ASTM C773

Standard Test Method for Compressive (Crushing) Strength of Fired Whiteware Materials

The compressive strength is determined on a right cylinder. Testing of at least ten specimens per type/brand is recommended by ASTM.
