1、Designation: D1489 09Standard Test Method forNonvolatile Content of Aqueous Adhesives1This standard is issued under the fixed designation D1489; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision. A number in
2、 parentheses indicates the year of last reapproval. Asuperscript epsilon () 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 Method Standard No. 1
3、75a.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 informationonly.1.3 This standar
4、d 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.

Sampling6.1 The sample of the adhesive shall be representative of thelot being evaluated. The quantity shall be at least 1.0 L aliquotconsisting of
10、a composite taken, when possible, from three ormore separate containers chosen at random. Thoroughly mixthe sample to uniform consistency. Immediately place thecomposite sample in an airtight glass jar until tested.7. Procedure7.1 Make sure that the sample in the glass jar is of uniformconsistency b
11、efore removing a specimen for testing. Inspectthe sample to ensure that there are no signs of settling orseparation of the adhesive. If settling or separation are noted,mix the samples thoroughly. Other factors, such as foaming orcontamination may require the samples be replaced.7.2 Test three 10-g
12、specimens from each composite sample.7.3 Weigh about 10 g of adhesive into a small beaker to thenearest 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 w

16、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 period of time mutually agreed uponbetween the manufacturer and the purchaser.7.5 Dry the sample in the bottle at 105 6
17、1C (221 6 2F)in the constant temperature oven until it has reached a constantweight. Determine this by removing the bottle, at predeter-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,
