Whiteware Refractory Laboratory Analysis & Testing Information
| ASTM # | Test Name | Description |
| C-67 |
Brick And Structural Clay Tile Testing. T9340 |
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. |
| C-279 |
Chemical Resistant Masonry Units. T9490 |
Granular samples are boiled in a sulfuric acid solution for a specified time period. the percent weight loss for two representative samples per type/brand is determined. |
| C-373 |
Water Absorption, Bulk Density, Apparent Porosity, And Apparent Specific Gravity of Fired Whiteware Products . T9515 |
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. |
| C-554 |
Crazing Resistance of Fired Glazed Ceramic Whitewares By A Thermal Shock Method. T9516 |
the resistance to crazing of fired glazed whitewares is determined when subjected to Thermal stresses. Specimens are initially heated at 250°C and water quenched. This cycle is repeated three times. If crazing dos not take place, Then the three cycles are repeated in 25°C increments up to 450°C. Failure is defined as the temperature at which crazing is observed. Testing of five specimens is suggested by ASTM. |
| C-674 |
Flexural Properties of Ceramic Whiteware Materials. T9517 |
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. |
| C-773 |
Compressive (Crushing) Strength of Fired Whiteware Materials. T9518 |
the compressive strength is determined on a right cylinder. Testing of at least ten specimens per type/brand is recommended by ASTM. |
