ASTM D889-99(2009) 松香中挥发性油的标准试验方法

Rosin and similar materials such as rosin derivatives often contain volatile material derived from the raw material used or formed as a result of the processing of the rosin. This volatile material can have a significant effect on the physical and chemical properties of the rosin and so a standard method for its determination is required.1.1 This test method covers the determination of the volatile oil content of rosin or similar material. The oil may consist of naturally occurring terpene oil, such as heavy fractions of turpentine, resulting from incomplete distillation in the processing of the rosin, or of foreign nonterpene oil resulting from incomplete removal of mineral or coal-tar solvent used to extract the rosin from wood or still wastes. In certain cases the volatile oil could consist of decarboxylated rosin formed during the processing of the rosin. 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 and health practices and determine the applicability of regulatory limitations prior to use.

ASTM D6404-99(2004) 含单宁的植物材料取样的标准操作规程

This practice provides standard procedures for obtaining representative samples of various materials used as a source of tannins for the tanning industry. Procedures are described for obtaining representative samples of economical and convenient quantities from a lot, or sections of a lot, of material for examination and analysis so that agreement may be reached with regard to the extent of variation of quality in different portions of a lot and the average quality of the entire lot of material. No directions for sampling, however explicit, can take the place of judgment, skill, and previous experience on the part of persons actually engaged in the sampling or the supervision of the sampling. These directions are intended to supplement that experience and, particularly, to serve as a guide in the selection of the method which is to be used, in common, by each of two or more contracting parties. Tanning materials contain moisture in varying amounts, depending both on the nature of the material and on the climatic conditions, so that sampling must be carried out as quickly as is consistent with thoroughness in order to avoid changes in moisture content.1.1 This practice covers obtaining representative samples from shipment lots of botanical materials containing tannin. 1.2 The values stated in SI units are to be regarded as the standard. The inch-pound units given in parentheses are for information only. 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.

This test method is used to determine the proportion of the total solids which are soluble solids and that proportion which are insoluble solids in a solution of tannin extract or in the water extract from raw or spent materials prepared for tannin analysis. The specimens are aliquots from the analytical solutions prepared from tannin extracts or the water extract solutions prepared from raw or spent materials. The soluble solids are defined as the portion of the total solids which are dissolved in the water and pass through a filter prepared by depositing a layer of Kaolin paste onto a standard filter paper. The insolubles are defined as the portion of the total solids which do not pass through the standard filter paper prepared with the layer of Kaolin paste. The results of this test method are dependent on a great many variables but particularly upon: 5.5.1 The temperature conditions under which the solutions were prepared and stored and the temperature at which the current analysis is performed; 5.5.2 The uniformity and consistency of the Kaolin paste layer deposited onto the filter paper; 5.5.3 The rate of solution run-out from the pipette; etc. It is, therefore, essential that the method be followed exactly in order to obtain reproducible results both among specimens within a laboratory and for analyses between laboratories.1.1 This test method is intended for use in determining the quantity of soluble solids and insolubles in solutions of tannin extracts, water extracts of vegetable tanning materials, or tanning liquors. This test method is applicable to the anlysis of liquid, solid, pasty, and powdered tannin extracts and to the water extracts of raw or spent materials. 1.2 The values stated in SI units are to be regarded as the 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 and health practices and determine the applicability of regulatory limitations prior to use.

Standard Test Method for Determining Non-Tannins and Tannin in Extracts of Vegetable Tanning Materials

ASTM D6387-99(2005) 通过毛细孔气相色谱对松节油和相关的萜烯产品的组成的标准试验方法

Earlier methods for characterizing turpentine and related terpene products were based on physical properties, such as those in Specification D 13 and Test Methods D 801 and D 802, and packed column gas chromatography for the major constituents (for example, α-pinene, β-pinene) as in Test Method D 3009. 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.1.1 These test methods describe the determination of the amounts of alpha-pinene, 945;-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 and health practices and determine the applicability of regulatory limitations prior to use.Note 18212;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. Subcommittee D01.34 will be working on this problem prior to the next version of this test method.

1.1 This specification covers the following kinds of spirits of turpentine as defined by the Naval Stores Act and Terminology D 804: gum spirits of turpentine, steam-distilled wood turpentine, sulfate wood turpentine, and destructively-distilled wood turpentine. 1.2 The purchaser should specify the kind of spirits of turpentine desired. 1.3 This specification is no longer widely used as it only specifies physical characteristics and not chemical composition. This specification was developed when the chief use for turpentine was as a solvent. Currently, especially in the United States, only a very limited quantity of turpentine is used as a solvent. Its main end use is as a raw material for the preparation of polyterpene type resins and synthetic organic chemicals. In spite of its limited application as a solvent, and hence the limited use of this specification, it is considered to be important to retain this specification. When information is required on chemical composition, gas chromatography is the recommended procedure (see Test Method D3009 ).
