Apparatus5.1 ViscometerUse the apparatus as described in TestMethods D 1084, Method B.5.2 Controlled-Temperature Chamber, capable of maintain
9、-ing temperature to 63C (65F), to provide temperaturestorage conditions.6. Storage of Adhesive6.1 Store the adhesive and all its components, if there areany, in their original and unopened containers when thecontainer is approximately litre (or quart) size. When theadhesive is supplied in larger con
10、tainers, the desired number ofsamples is withdrawn from the large container. In this lattercase, the size, type of closure, and nature (such as glass, steel,or tin-coated steel) of the small storage container is agreedupon by the purchaser and the manufacturer.6.2 For storage temperature, use any on
11、e of the standardtemperatures specified in Practice D 618. The time of storage isany time agreed upon by the purchaser and the manufacturer. Ifthe effect of storage time is desired, it is suggested that at leastthree quantities of the adhesive be stored under the prescribedconditions, and tested at
12、various intervals of time. Use aseparate, unopened container at each such test.7. Conditioning7.1 Condition all containers after storage at 23 6 3C (73.46 5F) before opening. If the adhesive consists of two or morecomponents, blend the components in accordance with the1This practice is under the jur
