BS 2782-9 Method 930A:1996 is a British Standard that specifies a method for determining the specific heat capacity of solid materials in the temperature range of 200°C to 700°C. The specific heat capacity of a material is the amount of heat required to raise the temperature of a unit mass of the material by one degree Celsius (or one Kelvin).
The standard provides a procedure for measuring the specific heat capacity using differential scanning calorimetry (DSC) equipment. Differential scanning calorimetry is a technique that measures the heat flow into or out of a sample as a function of temperature or time, while the sample is subjected to a controlled temperature program.
Specifically, in BS 2782-9 Method 930A:1996, the sample material is heated or cooled at a controlled rate, and the heat flow into or out of the sample is measured relative to a reference material under the same temperature program. The specific heat capacity is calculated from the heat flow data and the known properties of the reference material.
It's important to note that standards like BS 2782-9 Method 930A:1996 are essential for ensuring uniform testing and measurement procedures, allowing for accurate and comparable results across different laboratories and industries.
Please keep in mind that standards may be updated or revised over time, so it's always best to refer to the latest version or check for any updates beyond my knowledge cutoff date in September 2021.
