ISO 27971:2008规定了一种使用肺泡仪测定从通过工业碾磨或实验室试验碾磨生产的“软”至“硬”小麦粉(Triticum aestivum L.)获得的不同类型面团的流变特性的方法。ISO 27971:2008描述了alveograph测试以及如何使用实验室研磨机分两个阶段生产面粉:1)制备用于研磨的小麦颗粒，以使其更容易从胚乳中分离麸皮；和2)研磨过程本身，包括涉及三个凹槽辊的破碎系统、两个光滑辊之间的粒度减小以及使用离心筛分机对产品进行分级。

ISO 27971:2008 specifies a method of using an alveograph to determine the rheological properties of different types of dough obtained from “soft” to “hard” wheat flour (Triticum aestivum L.) produced by industrial milling or laboratory test milling.ISO 27971:2008 describes the alveograph test and how to use a laboratory mill to produce flour in two stages: 1) preparation of the wheat grain for milling to make it easier to separate the bran from the endosperm; and 2) the milling process itself, including the break system involving three fluted rollers, reduction of particle size between two smooth rollers and the use of a centrifugal sieving machine to grade the products.
