# ASTM C408

Standard Test Method for Thermal Conductivity of Whiteware Ceramics

[Back to all techniques](/analytical-techniques/)

## Significance and Use

2.1 This test method provides information useful in understanding and quantifying such parameters as thermal shock resistance and ability to conduct or dissipate heat.

## Scope

1.1 This test method covers a general procedure2 for determining the thermal conductivity of whiteware ceramics over the temperature range from 100 to 300 °F (40 to 150 °C).

1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
