ASTM C335 Test for Steady-State Heat Transfer Properties of Pipe Insulation

EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of ASTM C335 testing. This standard covers the measurement of steady-state heat transfer properties of pipe insulations.

Sample types include solid, flexible and loose fill; homogeneous and inhomogeneous; isotropic and non-isotropic; circular or non-circular cross-section. Includes measurement of metallic reflective insulation and bulk insulations with metal jackets or other elements with high axial conductivity; however, additional precautions should be taken and the specific procedures specified should be followed.

The test apparatus for this purpose is a pipe apparatus with a shielded tip or a calibrated tip. The shielded tip apparatus is a primary (or absolute) method. The shielded tip method is comparable but not the same as ISO 8497.

Values ​​stated in SI units or inch-pound units will be considered standard separately. The values ​​specified in each system may not be exactly equivalent; therefore, each system should be used independently of the other. Combining values ​​from the two systems may result in non-compliance with the standard.

Where appropriate or as required by specifications or other test methods, the following thermal transfer properties for the sample can be calculated from the measured data.
