1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

SIGNIFICANCE AND USE
4.1 This test method is not appropriate for alkali-soluble resins whose acid functionality is due to incorporated anhydrides. Variations in manufacture, storage, and possible contamination of anhydride functional resins may cause partial hydrolysis, or esterification, which will invalidate data from this test method. Anhydride functional resins should be characterized by Test Method D3644.  
4.2 This test method is used to measure a property of acid functionalized resins. Acid number determines the utility of resins as well as being a significant quality control measure.
SCOPE
1.1 This test method covers the measurement of the free acidity present in certain alkali-soluble resins.  
1.2 This test method is not suitable for styrene-maleic anhydride resins.  
1.3 The resin manufacturer should specify whether or not this test method may be used for his product(s).  
1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

SIGNIFICANCE AND USE
4.1 This test method is used to determine the property of acid functionality. Acid functionality determines the utility of the wax as well as being a significant Quality Control test.
SCOPE
1.1 This test method covers the determination of the acid number of synthetic waxes and natural waxes. The number is obtained by direct titration of the material and indicates the amount of free acid present.  
1.2 This test method, using an ethanol-xylene mixture, is applicable to all natural waxes, including carnauba. The test method is also applicable to oxidized microcrystalline waxes, oxidized Fischer-Tropsch, oxidized polyethylene, and montan esters.  
1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

SIGNIFICANCE AND USE
4.1 Waxes do not go through a sharp solid-liquid phase change when heated and therefore do not have a true melting point. As the temperature rises, waxes gradually soften or become less viscous. For this reason, the determination of the softening point must be made by an arbitrary but closely defined method if test values are to be reproducible.  
4.2 This test is useful in determining the consistency of waxes, and as one element in establishing the uniformity of shipments or source of supply.  
4.3 This test method has been found suitable for all types of waxes including paraffin, microcrystalline polyethylene, and natural waxes.
SCOPE
1.1 This test method covers the determination of the ASTM dropping point for waxes.  
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

SIGNIFICANCE AND USE
4.1 This test method is used to determine the property of styrene-maleic anhydride resins functionality. Acid functionality determines the utility of resin as well as being a significant quality control test.  
4.2 Because some of the anhydride functionality has been hydrolyzed in the manufacturing process, direct titration with base will produce erroneous data on the total acid content of the fully hydrolyzed resin in use. This test method charges excess alkali to hydrolize the anhydride functionality and neutralize the resulting acid. The remaining unreacted alkali is then back titrated with a standardized acid solution and the acid content is determined by difference.
SCOPE
1.1 This test method covers the measurement of the free acidity present in styrene-maleic anhydride resins.  
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

SIGNIFICANCE AND USE
4.1 This test method is used to determine a physical property of a wax and may determine the utility of the wax, as well as being a significant quality control test.
SCOPE
1.1 This test method describes the determination of the viscosity of polyethylene wax using small-volume, concentric cylinder, rotational viscometer and a temperature bath at 140 °C.  
1.2 The values stated in SI units are to be regarded as standard. The units in parentheses are provided for user convenience and are not standard.  
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

SIGNIFICANCE AND USE
4.1 In general, with materials of this type, softening does not take place at a definite temperature. As the temperature rises, these materials gradually and imperceptibly change from brittle solids to soft, viscous liquids. For this reason, the determination of the softening point must be made by a fixed, arbitrary, and closely defined methods if the results are to be comparable.
SCOPE
1.1 This test method covers the determination of the softening point of certain alkali-soluble resins having uniform plastic flow characteristics as the melting point is approached.  
1.2 The resin manufacturer should specify whether or not this test method may be used for his product(s).  
1.3 This test method is not suitable for styrene-maleic anhydride resins.  
Note 1: For testing rosin and other resins, see Test Method E28. For testing asphalts, tars, and pitches, see Test Method D2398.  
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

SIGNIFICANCE AND USE
4.1 This practice is suitable for all types of akalali-soluble resins. The resin manufacturer shall specify the percent ammonium hydroxide to be used (based on the equivalent weight of resin) and the maximum temperature to be used to achieve solution.
SCOPE
1.1 This practice is a procedure for preparing solutions of alkali-soluble resins in aqueous ammonia and determining the characteristics of such solutions.  
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

SIGNIFICANCE AND USE
4.1 This test method is used to determine the property of ester functionality. Ester functionality determines the utility of the wax as well as being a significant quality control test.
SCOPE
1.1 This test method covers the determination of the saponification number of synthetic waxes and natural waxes.  
1.2 This test method is applicable to Fischer Tropsche, microcrystalline, polyethylene, and Montan Ester waxes.  
1.3 Certain synthetic waxes, notably copolymers of ethylene, exhibit poor reproducibility when running saponification values. Reproducibility can be improved if cooking time in 7.2 is extended from 3 h to 18–20 h.  
1.4 Some oxidized polyethylene and other waxes with a melt temperature above 100°C may give poor reproducibility.  
1.5 Some dark-colored (Gardner Color 14) waxes may obscure the color change of the indicator, resulting in poor reproducibility.  
1.6 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
1.7 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.8 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

SIGNIFICANCE AND USE
4.1 This test method is used to determine the free acid content of MAH-grafted waxes. The potential hydrolysis of the anhydride functionality of this wax in storage makes them unsuitable for determining free acid content by Test Method D1386. Free acid content is a significant quality control test, and is a determinant of the utility of the wax.
SCOPE
1.1 This test method covers the determination of the acid number of maleic anhydride (MAH) grafted waxes. The number is obtained by direct titration of the material and indicates the amount of free acid present.  
1.2 This test method is applicable to MAH-grafted waxes because it uses a special sample preparation step (7.1) that is not required for other waxes. The special sample preparation reverses the hydrolysis of acid anhydride that can occur during storage of the wax.  
1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.1 This test method covers the determination of the acid number of synthetic waxes and natural waxes. The number is obtained by direct titration of the material and indicates the amount of free acid present.
1.2 This test method, using an ethanol-xylene mixture, is applicable to all natural waxes, including carnauba. The test method is also applicable to oxidized microcrystalline waxes, oxidized Fischer-Tropsch, oxidized polyethylene, and montan esters.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

SIGNIFICANCE AND USE
This test method is used to determine the property of maleic anhydride resins functionality. Maleic acid anhydride resins functionality determines the utility of resin as well as being a significant quality control test.
SCOPE
1.1 This test method covers the measurement of the free acidity present in certain alkali-soluble resins.
1.2 This test method is not suitable for styrene-maleic anhydride resins.
1.3 The resin manufacturer should specify whether or not this test method may be used for his product(s).
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

SIGNIFICANCE AND USE
In general, with materials of this type, softening does not take place at a definite temperature. As the temperature rises, these materials gradually and imperceptibly change from brittle solids to soft, viscous liquids. For this reason, the determination of the softening point must be made by a fixed, arbitrary, and closely defined methods if the results are to be comparable.
SCOPE
1.1 This test method covers the determination of the softening point of certain alkali-soluble resins having uniform plastic flow characteristics as the melting point is approached.
1.2 The resin manufacturer should specify whether or not this test method may be used for his product(s).
1.3 This test method is not suitable for styrene-maleic anhydride resins.

1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

SIGNIFICANCE AND USE
Waxes do not go through a sharp solid-liquid phase change when heated and therefore do not have a true melting point. As the temperature rises, waxes gradually soften or become less viscous. For this reason, the determination of the softening point must be made by an arbitrary but closely defined method if test values are to be reproducible.
This test is useful in determining the consistency of waxes, and as one element in establishing the uniformity of shipments or source of supply.
This test method has been found suitable for all types of waxes including paraffin, microcrystalline polyethylene, and natural waxes.
