ASTM D6793 - Isothermal Secant and Tangent Bulk Modulus
We perform the isothermal secant bulk modulus test by ASTM D6793 to measure a liquid’s compressibility. The greater the value of the isothermal secant bulk modulus, the less compressibility the liquid has. This is used in designing high-performance hydraulic fluid and braking systems.
