本标准实施规程描述了通过PFI磨（1）对纸浆进行处理，以评估造纸用纸浆质量。原则上，标准实践适用于所有类型的纸浆；在实践中，该方法可能不会对某些很长的纤维纸浆（如棉花）产生令人满意的结果。标准操作规程适用于处理少量试样，这些试样太小，无法在谷式打浆机中处理，如TAPPI T 200实验室纸浆处理（打浆机法）所述。

This standard practice describes the processing of pulp by means of the PFI mill (1) to evaluate pulp quality for papermaking.In principle, the standard practice applies to all types of pulp; in practice, the method may not give satisfactory results with certain very long-fiber pulps such as cotton.The standard practice is suited to processing small quantities of test specimens that are too small for processing in the Valley beater, as described in TAPPI T 200 Laboratory Processing of Pulp (Beater Method).
