Specific Heat - ASTM C351

The amount of energy required to raise the temperature of a unit mass of a material one degree. The heat capacity per unit mass of a material.

Testing is performed by measuring the temperature change of a known quantity of water (or other suitable calorimetric fluid) after the introduction of a heated test specimen. The test chamber is insulated to minimize heat loss.

The specific heat of the test material is calculated using:
cs = (mw * cw * ΔTw) / (ms * ΔTs)
where mw is the mass of the water,
cw is the specific heat of water,
ΔTw is the temperature change of the water,
ms is the mass of the specimen,
and ΔTs is the temperature change of the specimen.
