1、Designation: D 1489 97 (Reapproved 2004)Standard Test Method forNonvolatile Content of Aqueous Adhesives1This standard is issued under the fixed designation D 1489; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last r

2、evision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the Department of Defense. This test method replaces Method 4021 of FederalTest

3、Method Standard No. 175a.1. Scope1.1 This test method covers the determination of the non-volatile content of aqueous adhesives, such as dextrin, starch,casein, and animal gelatin.1.2 The values stated in SI units are to be regarded as thestandard. The values given in parentheses are for information

4、only.1.3 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2. Referen

5、ced Documents2.1 ASTM Standards:2D 907 Terminology of Adhesives3. Terminology3.1 DefinitionsMany terms in this test method are definedin Terminology D 907.4. Significance and Use4.1 Adhesive cost is often related to the solids level (non-volatile content).4.2 This test method can be used to compare

6、the nonvolatilecontent of various adhesives for adhesive selection and productuniformity.4.3 This test method is suitable for quality control andresearch purposes.5. Apparatus and Materials5.1 Analytical Balance, equipped with Class S weights orbetter, having a 200-g capacity, and accurate to 60.001

7、 g. Forthe initial weighing of the wet specimen, a laboratory balancehaving a capacity of 200 g and accurate to 60.01 g may beused.5.2 Constant-Temperature Oven, capable of maintaining atemperature of 105 6 1C (221 6 2F).5.3 Weighing BottlesWide-mouth cylindrical glass weigh-ing bottles, of flat for

8、m, about 30 mm in height and 50 mm indiameter, having interchangeable ground-in glass caps.5.4 Volumetric Flasks, of 200-mL capacity, with glass stop-pers.5.5 Volumetric Pipet, of 10-mL capacity.5.6 Desiccator, with drying agent and tray.5.7 Silica Sand.6. Sampling6.1 The sample of the adhesive shal

9、l be representative of thelot being evaluated and shall be a 0.9-L (1-qt) aliquot consist-ing of a composite taken, when possible, from three or moreseparate containers chosen at random. Before a sample istaken, thoroughly mix the contents of the container to uniformconsistency. Immediately place th

10、e composite sample in anairtight glass jar until tested.7. Procedure7.1 Make sure that the sample in the glass jar is of uniformconsistency before removing a specimen for testing.7.2 Test two 10-g specimens from each composite sample.7.3 Weigh about 10 g of adhesive into a small beaker to thenearest

11、 0.01 g. Disperse in 50 mL of hot distilled water andtransfer to a 200-mL volumetric flask. Rinse the beaker withsmall portions of hot distilled water and add rinsings to theflask. Dilute to mark with hot distilled water. Perform duplicatetests on each dispersion prepared in this manner.7.4 Pipet 10

12、 mL of the dispersion into a tared weighingbottle three quarters full of silica sand which has been dried toconstant weight.NOTE 1In the case of adhesives that do not reach constant weight, forexample those containing glycerin or slightly volatile plasticizers, makeone weighing after a specified per

13、iod of time mutually agreed uponbetween the manufacturer and the purchaser.1This test method is under the jurisdiction of ASTM Committee D14 onAdhesives and is the direct responsibility of Subcommittee D14.10 on WorkingProperties.Current edition approved April 1, 2004. Published April 2004. Original

15、TM website.1Copyright ASTM International, 100 Barr Harbor Drive, PO Box C700, West Conshohocken, PA 19428-2959, United States.7.5 Dry the sample in the bottle at 105 6 1C (221 6 2F)in the constant temperature oven until it has reached a constantweight. Determine this by removing the bottle, at prede

16、ter-mined times, and quickly weighing it on the scale. Once thesame weight is achieved in two consecutive weighings, returnthe sample to the oven for 5 min more. Then, cover the bottleand cool in a desiccator charged with desiccant to roomtemperature before weighing to the nearest 0.001 g.8. Calcula

17、tion8.1 Calculate the percent of nonvolatile content as follows:Nonvolatile matter, % 5 W1/W2! 3 2000where:W1= weight of dried residue, andW2= weight of original 10-g specimen.9. Accuracy of Test9.1 Repeat the tests once if the results obtained in the fourtests on a sample cover a range of more than

18、 2 percentageunits.10. Report10.1 Report the following information:10.1.1 Complete identification of the adhesive tested, in-cluding type, source, manufacturers code number, lot or batchnumber, condition, and date.10.1.2 Number of containers received and number sampled.10.1.3 Number of specimens tes

19、ted (only if retested inaccordance with Section 9).10.1.4 Maximum, minimum, and average nonvolatile con-tent, in percent. If a retest is made, report both sets of results.11.
