applicable to this practice.

3.1.2 cellulose ester, n—derivatives of cellulose in which

one or more of the hydroxyl hydrogens have been replaced by

acyl groups.

3.1.3 cellulose ether, n—derivatives of cellulose in which

one or more of the hydroxyl hydrogens have been replaced by

alkyl groups.

3.1.4 cellulose nitrate (nitrocellulose), n—derivatives of

cellulose in which one or more of the hydroxyl hydrogens have

been replaced by nitrate groups.

3.1.5 emulsion vehicle, n—an emulsion of binder in water.

The binder may be oil, oleoresinous varnish, resin, or other

emulsiﬁable liquid.

3.1.6 latex, n—a stable aqueous dispersion of synthetic

resin, produced by emulsion polymerization, as the principal

constituent of the binder.

This practice is under the jurisdiction of ASTM Committee D01 on Paint and

Related Coatings, Materials, and Applications and is the direct responsibility of

3.1.7 shellac varnish, n—a solution or “cut” of a speciﬁed

type and grade of dry lac resin in a suitable alcohol.

3.1.8 varnish, n—a liquid composition that is converted by

oxidation or thermal cross-linking to a transparent or translu-

cent solid ﬁlm after application as a thin layer.

4. Signiﬁcance and Use

4.1 The nonvolatile content of raw materials may be used to

determine the total nonvolatile content (solids) of paint and

related coatings. Such information may be useful to coatings

producers and users for the determination of the total solids

available for ﬁlm formation and for the estimation of the

volatile organic content.

5. Procedure

5.1 Cellulosics:

5.1.1 Test Methods D1644, Method A, should be used for

determining the amount of alcohol present in nitrocellulose

shipments. This method may also be used for other cellulose

derivatives if mutually agreed upon by producer and user.

5.1.2 Moisture in three different cellulose derivatives may

be determined using test methods given in the following

standards:

Cellulose Derivative ASTM Standard Section

Cellulose acetate D871 3–4

Ethylcellulose D914 4–6

Methylcellulose D1347 3–4

5.2 Emulsions and Latices:

5.2.1 Test Method D2369, Procedure B may be used to

determine the nonvolatile and volatile content of most emul-

sions. Important considerations are the presence of volatile

plasticizers and surfactants and the presence of oxidizable

components in oleoresinous vehicles and drying oil modiﬁed

alkyds.

5.2.2 Test Method D4758 should be used to determine the

nonvolatile and volatile content of synthetic latex samples.

5.3 Resin Solutions:

5.3.1 Test Methods D1259, Method A is recommended for

solutions of non-heat reactive resins that remain stable and

release solvents under the test conditions. Examples include

alkyds and rosin esters.

5.3.2 Test Methods D1259, Method B is recommended for

solutions of heat reactive resins that undergo condensation or

other reactions or both under the inﬂuence of heat. Examples

include the formaldehyde reaction products of urea, melamine,

and phenols. Method B is also recommended for resin solu-

tions that release solvent slowly, for example, epoxy resin and

vinyl resin solutions when these contain high boiling solvents.

5.3.3 Method A and Method B of Test Methods D1259

differ primarily in the longer drying time speciﬁed for Method

B (2 h versus 30 min). In both methods, a weighed specimen

of resin solution is spread under pressure between two weighed

sheets of aluminum foil, which are then separated and dried at

105 °C. The method is unique in that it provides for drying of

very thin ﬁlms of resin, minimizing chances for volatiles to be

trapped.

5.4 Shellac:

5.4.1 Sections 14 and 15 of Test Methods D29 describe two

methods for the determination of volatile matter (moisture) in

lac resins. Method A (Section 14) is recommended for orange

shellac, button lac, garnet lac, and dry bleached lac. Method B

(Section 15) is recommended for bleached lac in the form of

hanks, bars, and crushed fresh ground (see Speciﬁcation

D360).

5.4.2 Sections 14 to 16 of Test Methods D1650 are recom-

mended for the determination of the nonvolatile and volatile

content of shellac varnishes.

5.5 Varnishes:

5.5.1 Test Methods D1644 describes two methods for the

determination of the nonvolatile and volatile content of var-

nishes. Method A requires heating a 1.2 g specimen at 105 °C

for 3 h in an oven, while Method B requires heating a smaller

specimen at 149 °C for 10 min on a hotplate. Method A may

give high results due either to incomplete elimination of

volatile matter or to absorption of oxygen by oxidizing-type

varnishes.

5.5.2 Sections 18 to 22 of Test Methods D115 is applicable

to the following classiﬁcations of varnishes used for electrical

insulation: alcohol-soluble varnishes, oxidizing air-drying

varnishes, thermosetting varnishes, oxidizing baking varnishes,

air-drying asphaltic varnishes, silicone varnishes, and thermo-

setting laminating varnishes. Determine nonvolatile matter in

electrical insulating varnishes intended for electrical equipment

operating at 180 °C and above in accordance with Test Meth-

ods D115 except that the temperature used shall be 135 °C 6

3 °C (275 °F 65.5 °F) or at a temperature agreed upon

between the producer and user.

6. Precision

6.1 Some of the referenced ASTM standards have precision

limits. Reference to the individual standards for precision

statements is recommended.

7. Keywords

7.1 emulsions; nonvolatile content of cellulosics; volatile

content of cellulosics
