3、ncies of the U.S. Department of Defense.1. Scope1.1 This test method covers the determination of nonvolatilematter (total solids) in a water-emulsion, organic solvent-basedliquid and paste floor polishes, and polymer-emulsion-typefloor polishes.1.2 This test method recognizes that the products mayco
4、ntain material that will slowly volatilize or change chemi-cally with a resulting change in weight of the nonvolatilematter. Therefore, since drying to constant weight isimpractical, specific drying times have been selected.1.3 The values stated in SI units are to be regarded as thestandard. The val
5、ues given in parentheses are for informationonly.1.4 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 re
6、gulatory limitations prior to use.2. Significance and Use2.1 Nonvolatile matter determination is useful as a qualitycontrol test, when used in conjunction with other tests, toassure specification compliance.3. Apparatus3.1 Flat-Bottom Dishes:3.1.1 For water-emulsion floor polishes and polymer-emulsi
7、on-type floor polishes, use aluminum dishes 1.5 cm deepand 6 cm in diameter.3.1.2 For solvent-based floor polishes, use glass dishes 4.5cm deep and 6 cm in diameter, with covers.3.2 Analytical Balance, with a sensitivity of 0.1 mg.3.2.1 Drying Oven, Convection-Type, capable of maintain-ing a tempera
8、ture of 105.0 6 2.5C (221.0 6 4.5F). If manydeterminations of solvent-based floor polishes are being madeat the same time, an explosion-proof oven should be used.4. Sampling4.1 The sample shall be thoroughly representative of thematerial in question, and the test specimen shall be thoroughlyrepresen
9、tative of the sample itself.5. Procedure5.1 Bring the material to be tested to equilibrium tempera-ture at 23 6 2C (73.4 6 3.6F).5.2 Making the determination in duplicate, place approxi-mately2gofwater-emulsion floor polish, or solvent-basedfloor polish specimen, or 1 g of polymer-emulsion-type floo
10、rpolish specimen into a tared, dried, flat-bottom aluminum dishof the previously specified size. Weigh rapidly, and place in theoven maintained at 102.5 to 107.5C. The starting time in theoven is the point at which the oven has returned to temperatureafter loading. After heating for 4 h for water-em
11、ulsion floorpolish, 16 h for solvent-based floor polish, or 2 h for polymer-emulsion-type floor polishes. Cool in a desiccator. Weigh to thenearest 0.1 mg.5.3 Do not overload the oven, and provide space at leastequal to the diameter of the dishes between dishes in the oven.6. Calculation6.1 Multiply
12、 the weight of total solids by 100 and divide bythe weight of the sample to obtain the percentage of nonvolatilematter.7. Precision and Bias7.1 PrecisionDuplicate determination should not differ bymore than 0.2 %.7.2 BiasThis test method has no bias because the resultsdeveloped are defined only in t
