PULPS - DETERMINATION OF DRAINABILITY - PART 1: SCHOPPER-RIEGLER METHOD (ISO 5267-1:1999, IDT)
MS ISO 5267-1:2008, AMD. 1:2010 (CONFIRMED:2023)
Status : 2nd Confirmation
Format : PDF

This Malaysian Standard specifies a method for the determination of the drainability of a pulp suspension in water in terms of the Schopper-Riegler (SR) number. 
The Schopper-Riegler test is d ....Read more esigned to provide a measure of the rate at which a dilute suspension of pulp may be dewatered. It has been shown that the drainability is related to the surface conditions and swelling of the fibres, and constitutes a useful index of the amount of mechanical treatment to which the pulp has been subjected.

In principle, this method is applicable to all kinds of pulp in aqueous suspension. However, in practice, the Schopper-Riegler test provides acceptable results only if a sufficiently dense mat of fibres is formed on the wire screen. For this reason, the test is not recommended for some extremely short-fibred pulps, such as those from well-beaten hardwoods, as most of the fibres will pass through the wire screen, resulting in anomalous reduction of the SR number. The most reliable results are o Close

The cetane number provides a measure of the ignition characteristics of diesel fuel oil in compression ignition engines. The cetane number is determined at constant speed in a pre-combustion chamber-type compression ignition test engine. However, the relationship of test engine performance to full scale, variable speed, variable load engines is not completely understood. 
This Malaysian Standard is applicable for the entire scale range from zero cetane number (CN) to 100 CN but typical testing is in the range of 30 CN to 65 CN.

This test may be used for unconventional fuels such as synthetics, vegetable oils, etc. However, the relationship to the performance of such materials in full scale engines is not completely understood.
