Methods of Testing Pulp and Paper The Determination of Freeness
1.1
The Canadian Standard Freeness test is designed to give a measure of the
rate at which a dilute suspension of pulp may be dewatered. The drainage rate,
or freeness, has been shown to be related to the surface conditions and
swelling of the fibres, and is a useful index of the amount of mechanical
treatment given to the pulp.

Petroleum products — Total sediment in residual fuel oils — Part 2: Determination using standard pro...
The principle of the method specified is determining the total sediment after accelerated ageing according to two procedures: A - thermal ageing (at 100 °C for 24 h), B - chemical ageing (dilution with hexadecane, heating to 100 °C for 1 h), followed by hot filtration as specified in ISO 10307-1. The object is to predict fuel oil stability to sedimentation during storage and handling.
