标准范围

要求将吸油值与同时在商定的产品样品上测定的值进行比较。该方法的原理基于从滴定管向试验部分添加亚麻籽油。每次添加后，将油揉入产品中，直到形成团块。当形成光滑稠度的糊状物时，停止添加油。它应该只是蔓延，没有开裂或崩溃。阅读滴定管并记下使用的油量。结果以每100克产品的毫升油或每100克产品的克油表示。-取消并替换ISO/R 787-1968第5部分。

The oil absorption value is required to be compared with the value determined at the same time on an agreed sample of the product. The principle of the method is based on addition of linseed oil from a burette to the test portion. After each addition, rub the oil into the product until conglomerates are formed. Cease the addition of oil when a paste of smooth consistency has been formed. It should just spread without cracking or crumbling. Read the burette and note the quantity of oil used. The result is expressed in millilitres of oil per 100 g of product or in grams of oil per 100 g of product. - Cancels and replaces Part 5 of ISO/R 787-1968.
