IP 444 - Cloud Point - Optical Detection Stepped Cooling Method

We perform testing by IP 444 to determine the cloud point or temperature where biodiesel fuel or petroleum products begin to gel, forming crystals or clouds. For petroleum products and biodiesel fuels, 'cloud point' is the temperature at which the product begins to form clusters of hydrocarbon crystals, or 'clouds'.  This can lead to plugged filters and other engine performance problems in cool weather. This test method only covers petroleum products and biodiesel fuels that are transparent in layers 40mm thick.

We also perform cloud point testing by ASTM D2500ASTM D5771ASTM D5773DIN 51597FTM 202FTM 203IP 446ISO 3015MIL-DTL-17111 §, and MIL-H-22072 §4.6.7. These different test methods use different instruments or procedures or are used for certain sample types.
