ASTM D6387-19(2023)(Test Method)
Standard Test Methods for Composition of Turpentine and Related Terpene Products by Capillary Gas Chromatography

SIGNIFICANCE AND USE
5.1 Earlier methods for characterizing turpentine and related terpene products were based on physical properties, such as those in Specification D13 and Test Methods D801 and D802, and packed column gas chromatography for the major constituents (for example, α-pinene, β-pinene) as in Test Method D3009. As terpene products became widely used as chemical raw material, the separation and quantitation of compounds present at lower concentrations in the product became more important. The capillary gas chromatographic technique described in these test methods is a rapid and convenient means to perform these analyses.
SCOPE
1.1 These test methods describe the determination of the amounts of α-pinene, β-pinene, dipentene, terpene alcohols, and other terpene compounds in turpentine and related terpene products using capillary gas chromatography. The two methods for determining the amount of the individual terpene compounds are the “internal standard” method, which yields absolute values, and the “area percent” method, which yields relative values.  
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 the standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
Note 1: Overall this test method gives excellent repeatability but only moderate reproducibility. This greater than normal differential is a consequence of the variety of gas chromatography (GC) columns and other variables used by participants. These variables, coupled with the complex composition of the test products, enabled some workers to separate peaks that others reported as one peak; thus, this test method gives excellent precision within a given laboratory on a given GC. When laboratory to laboratory comparison have to be made, however, it is essential that the GC operating conditions be defined closely.  
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.

Standard Test Method for Odor of Volatile Solvents and Diluents

SIGNIFICANCE AND USE
3.1 The comparative odor characteristics can be used, combined with other tests, for product identification and assessing compliance with a specification.  
3.2 The residual odor characteristics can be used to judge the presence of relatively nonvolatile materials that may be associated with manufacture or contamination during distribution. Since volatile solvents and diluents are used in a wide variety of chemical processes and residual materials may affect the efficiency of such processes, this test method provides a comparative test for manufacturing control and assessing compliance with a specification.
SCOPE
1.1 This test method covers a comparative procedure for observing the characteristic and residual odors of volatile organic solvents and diluents to determine their odor acceptability in a solvent system.  
1.2 It is not intended that this test method be employed to determine subtle odor differences between materials or to determine odor intensity.  
1.3 It is recommended that this test method not be employed to determine the residual odor of a liquid if its time for evaporation to dryness at room temperature exceeds 30 min or as agreed upon.  
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. For specific hazard statements, see Section 4.  
1.6 For specific hazard information, see the supplier's Material Safety Data Sheet (MSDS).

Standard Test Method for Determination of Hydroquinone (HQ) Content in Vinyl Acetate Monomer (VAM) Using Ultraviolet-Visible (UV-Vis) Spectrophotometer

SIGNIFICANCE AND USE
4.1 VAM is an organic vinyl ester compound. This colorless liquid is the precursor to polyvinyl acetate, an important industrial polymer. VAM may be subject to rapid spontaneous polymerization if the inhibitor is not present or becomes depleted during prolonged storage.  
4.2 VAM is typically shipped with a HQ inhibitor as free radical scavenger. VAM should be evaluated to ensure that appropriate systems (for example, temperature and inhibitor quantity) are assured during storage, transportation, and getting prolonged shelf life.  
4.3 Most VAM shipped from the manufacturer will contain an inhibitor, typically 3 to 5 ppm HQ for regional shipments and up to 25 ppm HQ for long-range shipments.
SCOPE
1.1 This test method covers the determination of hydroquinone (HQ) in colorless vinyl acetate monomer (VAM). This test method is applicable to the determination of HQ in the concentration range from 1 to 25 ppm.  
1.2 For purposes of determining conformance of an observed or a calculated value using this test method to relevant specifications, test result(s) shall be rounded off “to the nearest unit” in the last right-hand digit used in expressing the specification limit in accordance with Practice E29.  
1.3 For ensuring safety, hazard information and guidance, follow the manufacturer’s material safety data sheet.  
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.

ASTM D233-13(2022)(Test Method)
Standard Test Methods of Sampling and Testing Turpentine

SIGNIFICANCE AND USE
3.1 The test procedures described in this standard were developed when the chief use for turpentine was as a solvent. Currently however, the chief use for turpentine (and pinenes) is as raw materials for the production of resins and synthetic organic chemicals. Thus the chemical composition of turpentines and pinenes is extremely important and tests, in addition to the ones described in these test methods, are required in order to fully characterize turpentines and pinenes. The most widely used technique for determining the chemical composition of turpentines (and pinenes) is gas chromatography (see Test Methods D6387).
SCOPE
1.1 These test methods cover procedures for sampling and testing turpentine, as defined by the Code of Federal Regulations and Terminology D804. These test methods are also used for the sampling and testing of pinenes, the major components of most turpentines.  
1.2 These test methods primarily measure the physical rather than the chemical properties of turpentines and pinenes. As turpentines and pinenes are currently used chiefly as chemical raw materials for the production of resins and synthetic organic chemicals, chemical composition is also very important. Consequently, testing the chemical composition of turpentines and pinenes by gas chromatography has displaced these test methods to a large extent. (See for example Test Methods D6387.)  
1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered 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.

Standard Test Methods for Sampling and Testing Dipentene

SIGNIFICANCE AND USE
3.1 The testing procedures described in these test methods have been in use for many years and emphasize the physical properties rather than the chemical composition of dipentene. These procedures were sufficient when dipentene was used primarily as a solvent. Currently, however, dipentene finds application as a chemical raw material and a knowledge of its chemical composition is therefore important. Test Methods D6387 describe a capillary gas chromatography method which is suitable for determining both the major and minor components found in dipentene.
SCOPE
1.1 These test methods cover procedures for sampling and testing dipentene and related terpene solvents, consisting chiefly of monocyclic terpene hydrocarbons distilling above the range for turpentine.

ASTM D890-12(2022)(Test Method)
Standard Test Method for Water in Liquid Pine Chemicals

SIGNIFICANCE AND USE
3.1 Many pine chemical products contain water as a result of the processes used for their production. Typically refined products such as terpenes, pine oil, tall oil fatty acids, and distilled tall oil contain only traces of water, but crude tall oil might contain 0.5 % to 2.5 % of water. Although the Karl Fischer and coulometric methods are most applicable to low levels of moisture, these can be and are used at higher levels. The azeotropic distillation method is generally used at higher levels.
SCOPE
1.1 These test methods cover the quantitative determination of dissolved or occluded water present in any proportion in liquid pine chemicals, such as turpentine, pinene, dipentene, pine oil, tall oil, and tall oil fatty acids. Three methods of moisture testing are included. The Karl Fisher titration method is the preferred method for testing tall oil, Test Methods D803.  
1.1.1 The Karl Fischer Titration method is based on the reaction between water and a complex reagent2 consisting of iodine, sulfur dioxide, pyridine, and methanol, whereby the iodine is converted to a colorless compound. The appearance of a persistent iodine color in the reaction mixture indicates the complete removal of free water by reaction with the reagent, and the endpoint may be measured colorimetrically. Automatic titrators find this endpoint by the restoration of a current strength when the resistance provided by the presence of water is eliminated. Amperometric automatic titrators find this endpoint by detecting the current flow that occurs once water is eliminated.  
1.1.2 The coulometric titration method determines water content by electronic integration of a current sufficient to generate the precise amount of iodine from the required reagent to react with the water in the sample.  
1.1.3 The azeotropic method utilizes the relatively low boiling point of water, as compared with other sample constituents, in a toluene or xylene matrix so that water is collected in a trap and measured.  
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.

ASTM D804-12(2022)(Terminology)
Standard Terminology Relating to Pine Chemicals, Including Tall Oil and Related Products

SCOPE
1.1 Although the pine chemical industry has been a continuing producer of chemical products for many centuries, the nature of the industry, its products, and its terminology have changed. In particular, the original practice of recovering pine chemical through the processing of the exudate from pine trees has been supplemented by their extraction by solvent products of the wood pulping industry. For many years the industry was known as the Naval Stores industry but that term has gradually been replaced by the more descriptive and meaningful term, Pine Chemicals Industry. Thus, this terminology contains some old terms now mostly of historic value, together with the terms of the modern pine chemical industry.2  
1.2 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.

Standard Test Method for Acetone, Methyl Acetate, and Parachlorobenzotrifluoride Content of Paints, and Coatings by Solid Phase Microextraction-Gas Chromatography

SIGNIFICANCE AND USE
5.1 In order to calculate the volatile organic content (VOC) of paints containing EPA exempt solvents, it is necessary to know the acetone, methyl acetate, or parachlorobenzotrifluoride content. This gas chromatographic test method provides a simple and direct way for measuring these solvents. Each analyte is measured with respect to a unique internal standard. For acetone, the internal standard used is acetone-d6, for methyl acetate it is methyl acetate-d3, and for PCBTF it is metachlorobenzotrifluoride (MCBTF). These unique analyte/internal standard pairs behave very nearly as single solvents with respect to evaporation rate and adsorption rate onto a coated silica fiber (SPME) but are separable on a gas chromatograph (GC) capillary column. The only critical analytical technique required for successfully performing this test method is the ability of an analyst to weigh a paint sample and internal standard, corresponding to the analyte of interest, into a septum capped vial. After weighing, solvent evaporation has no effect on the final value of the determination. Since whole paint is not injected into the gas chromatograph, the analytical system is never compromised.
SCOPE
1.1 This test method is for the determination of acetone, methyl acetate, or parachlorobenzotrifluoride (PCBTF), or combination of any of the three, in paints and coatings, by solid phase microextraction (SPME) headspace sampling, and subsequent injection into a gas chromatograph. It has been evaluated for cellulose nitrate, acrylic, and urethane solvent-borne systems. The established working range of this test method is: acetone, 28 to 90 %; methyl acetate, 12 to 22 %; parachlorobenzotrifluoride, 10 to 17 %. There is no reason to believe that it will not work outside these ranges. A minor modification of this test method would make it suitable for the analysis of the same analytes in water-borne coatings (see Note 1).
Note 1: Water-borne paints are internally standardized and diluted with water followed by addition of solid sodium chloride.  
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.
