HOW TO SUBSCRIBE
For the purpose of this method, consistency is defined as the oven-dry weight of suspended matter per 100 g of stock. The method is applicable to all kinds of aqueous pulp suspensions, which may contain fillers or additives.
Using the following defined testing conditions, a consistency measurement of known precision is obtained.
The method is a gravimetric one. A known weight of suspension is filtered in a Büchner funnel and the retained solids are dried and weighed. Since stock suspensions have been known to include as much as 6% by volume of air, this method cannot be applied to stock flow measurements.
For good sampling, a high degree of agitation is necessary, as the uniformity of the stock suspension is somewhat proportional to the degree of agitation. This should be kept in mind when locating the sampling station.
