Standard Test Method for Water in Organic Liquids by Coulometric Karl Fischer Titration

SIGNIFICANCE AND USE
4.1 The coulometric technique is especially suited for determining low concentrations of water in organic liquids that would yield small titers by the Karl Fischer volumetric procedure. The precision and accuracy of the coulometric technique decreases for concentrations of water much greater than 2.0 % because of the difficulty in measuring the small size of sample required. The test method assumes 100 % efficiency of coulombs in iodine production. Provision is made for verifying this efficiency. (See Table 1 and Note 5.)
SCOPE
1.1 This test method covers the determination of water from 0 % to 2.0 % mass in most liquid organic chemicals, with Karl Fischer reagent, using an automated coulometric titration procedure. Use of this test method is not applicable for liquefied gas products such as Liquid Petroleum Gas (LPG), Butane, Propane, Liquid Natural Gas (LNG), etc.  
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 Review the current Safety Data Sheets (SDS) for detailed information concerning toxicity, first-aid procedures, handling, and safety precautions.  
1.4 This standard does not purport to address all of the safety problems, 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. Specific precautionary statements are given in Section 8.  
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.

ASTM E324-23(Test Method)
Standard Test Method for Relative Initial and Final Melting Points and the Melting Range of Organic Chemicals

SIGNIFICANCE AND USE
5.1 It has long been recognized that narrow melting range and high final melting point are good indications of high purity in crystalline organic compounds. Several ASTM test methods use these criteria to assay the purity of organic compounds (Note 1).
Note 1: Other ASTM test methods using melting (or freezing point) data to indicate sample purity are Test Methods D852 and D6875.  
5.2 The relatively simple and rapid test prescribed in this test method shows the sample under test to be either more or less pure than the standard sample. For specification purposes, a minimum allowable purity can be assured by setting limits on the differences in final melting points and the melting ranges between the standard sample and the sample under test.
SCOPE
1.1 This test method covers the determination, by a capillary tube method, of the initial melting point and the final melting point, which define the melting range, of samples of organic chemicals whose melting points without decomposition fall between 30 °C and 250 °C.  
1.2 This test method is applicable only to crystalline materials that are sufficiently stable in storage to met the requirements of a satisfactory standard sample as defined in Section 7.  
1.3 This test method is not directly applicable to opaque materials or to noncrystalline materials such as waxes, fats, and fatty acids.  
1.4 Review the current Safety Data Sheets (SDS) for detailed information concerning toxicity, first aid procedures, handling, and safety precautions.  
1.5 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
1.6 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.  
1.7 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 Practice for Sampling Industrial Chemicals

SIGNIFICANCE AND USE
5.1 Representative samples of industrial chemicals are required for the determination of chemical and physical properties which are used to establish standard volumes, prices, and compliance with commercial and regulatory specifications.  
5.2 The objective of sampling is to obtain a small portion (spot sample) of material from a selected area within a container which is representative of the material in the area or, in the case of running or all-level samples, a sample whose composition is representative of the total material in the container. A series of spot samples may be combined to create a representative sample.  
5.3 Manual and Automatic Sampling Considerations—The selection of manual or automatic sampling devices is part of establishing a sampling plan applied under all conditions within the scope of this practice provided that the proper sampling procedures are followed. Both types of sampling are commonly used for liquid, solid, and slurry sampling and require adherence to the following:  
5.3.1 An adequate frequency of sampling must be selected.  
5.3.2 The equipment to support manual or automatic sampling systems may be obtained commercially, fabricated from the designs presented in this practice, or constructed as needed to satisfy process design or other specific requirements.  
5.3.3 The sampling equipment must be maintained on a regular basis, and the sampling plan adopted must be strictly followed.
SCOPE
1.1 This practice covers procedures for sampling several classes of industrial chemicals. It also includes recommendations for determining the number and location of such samples, to ensure their being representative of the lot in accordance with accepted probability sampling principles.  
1.2 Although this practice describes specific procedures for sampling various liquids, solids, and slurries, in bulk or in packages, these recommendations only outline the principles to be observed. They should not take precedence over specific sampling instructions contained in other ASTM product or method standards.  
1.3 These procedures are covered as follows:

7 – 11    
Simple Liquids  
12 – 27    
Solids  
28 – 35    
Slurries

Standard Test Method for Color of Liquids Using Tristimulus Colorimetry

SIGNIFICANCE AND USE
4.1 The primary objective of the visual method of Pt-Co color measurement, as defined in Test Method D8005, is to rate specific materials for yellowness. This yellowness is frequently the result of the undesirable tendency of liquid hydrocarbons to absorb blue light due to contamination in processing, storage or shipping.  
4.2 Clear liquids can be rated for light absorbing yellowish or brownish contaminants using scales that simulate the long-established visual-comparison method.
SCOPE
1.1 This test method covers an instrumental method for the CIE (Commission International de l’Eclairage) tristimulus measurement of the color of near-clear liquid samples. The transmission measurement values are converted to the color scale in the platinum-cobalt (Pt-Co) system.  
1.2 This test method has been found applicable to the color measurement of clear, liquid samples, free of haze, with nominal Pt-Co color values in the 0 to 100 range. It is applicable to non-fluorescent liquids with light absorption characteristics similar to those of the Pt-Co color standard solutions.  
1.3 The tristimulus colorimetry may be calculated from spectral measurements or be obtained directly from a colorimeter. Practice E1455 provides some guidance on colorimeters, while Test Methods D1686 and D2108 deal with the visual and instrumental measurement of near-clear liquids.  
1.4 In determining the conformance of the test results using this method to applicable specifications, results shall be rounded in accordance with the rounding off methods of Practice E29.  
1.5 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
1.6 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. For specific hazard statements, see Section 8.

Standard Guide for Management of Investigation-Derived Waste Associated with PFAS

SIGNIFICANCE AND USE
4.1 Perfluoroalkyl and polyfluoroalkyl substances (PFAS) are a family of more than 4700 synthetic organic chemicals. PFAS can withstand high temperatures and survive highly corrosive environments. They are used in the manufacture of coatings, surface treatments, and specialty chemicals in cookware, carpets, food packaging, clothing, cosmetics, and other common consumer products. PFAS also have many industrial applications and are an active ingredient in certain types of fire-fighting foams (aqueous film-forming foams, or AFFF). PFAS coatings resist oil, grease, and water. PFAS are persistent compounds. Therefore, PFAS should be considered for purposes of managing investigation-derived waste where PFAS is known or suspected to be present in environmental media.  
4.1.1 PFAS are emerging contaminants for which environmental regulations and guidance are dynamic and are being developed simultaneously at federal, state, local, and international levels as more is learned about their characteristics, environmental fate, and management/treatment. Therefore, site-specific rules, regulations, and guidance should be evaluated for options and restrictions on management of PFAS  investigation-derived waste. For example, the Massachusetts Department of Environmental Protection has determined that PFAS wastes are “hazardous materials” subject to the Massachusetts Oil and Hazardous Material Release Prevention and Response Act (M.G.L. Chapter 21E) and the Massachusetts Contingency Plan. Other states and jurisdictions may have or will develop and implement similar determinations that affect the on-site management, storage, and labeling and off-site transportation requirements for PFAS  investigation-derived waste.  
4.1.2 Given the characteristics and persistence of PFAS compounds, PFAS  investigation-derived waste presents special handling and treatment/disposal considerations. EPA recently issued Interim Guidance on the Destruction and Disposal of Perfluoralkyl and Polyfluoralky...
SCOPE
1.1 Existing guidance on the management of investigation-derived waste is focused upon cuttings, purge water, personal protective equipment, and other miscellaneous solid waste generated at property that may be impacted by the release of hazardous materials and hazardous substances. These hazardous substances include, but are not limited to, heavy metals, petroleum, petroleum byproducts, solvents, polycyclic aromatic hydrocarbons, organic and inorganic corrosives, radioactive material, and explosives. Guidance on the management of investigation derived waste generated at sites that may be impacted by releases of perfluoroalkyl and polyfluoroalkyl substances (PFAS) is limited. This standard guide addresses this deficiency  
1.2 This guide describes best practices for managing investigation-derived waste associated with PFAS that are consistent with federal and state policies and regulations at the date of issuance. The user is advised to determine if new regulations or rules have been promulgated by the state, federal, or tribal regulatory agency having jurisdiction over the property.  
1.3 This guide describes considerations to prevent the unintended and unauthorized disposal of liquid investigation-derived waste that may contain PFAS into wastewater treatment plants or systems that are not permitted to receive these waste streams.  
1.4 This guide describes considerations to prevent the unintended and unauthorized disposal of solid investigation-derived waste that may contain PFAS into landfills or other solid waste disposal facilities that are not permitted to receive these waste streams.  
1.5 This guide describes several stormwater pollution prevention best management practices applicable to investigation-derived waste.  
1.6 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,...

Standard Test Method for Distillation of Heavy Hydrocarbon Mixtures (Vacuum Potstill Method)

SIGNIFICANCE AND USE
5.1 This test method is one of a number of tests conducted on heavy hydrocarbon mixtures to characterize these materials for a refiner or a purchaser. It provides an estimate of the yields of fractions of various boiling ranges.  
5.2 The fractions made by this test method can be used alone or in combination with other fractions to produce samples for analytical studies and quality evaluations.  
5.3 Residues to be used in the manufacture of asphalt can also be made but may not always be suitable. The long heat soaking that occurs in this test method may alter some of the properties.
Note 1: While the practice of reblending distillates with residue can be done to produce a lighter residue, it is not recommended because it produces blends with irregular properties.  
5.4 Details of cutpoints must be mutually agreed upon before the test begins.  
5.5 This is a complex procedure involving many interacting variables. It is most important that at the time of first use of a new apparatus, its components be checked as detailed in Annex A1 and Annex A2 and that the location of the vapor temperature sensor be verified as detailed in 6.5.3 and Fig. 1.
SCOPE
1.1 This test method covers the procedure for distillation of heavy hydrocarbon mixtures having initial boiling points greater than 150 °C (300 °F), such as heavy crude oils, petroleum distillates, residues, and synthetic mixtures. It employs a potstill with a low pressure drop entrainment separator operated under total takeoff conditions. Distillation conditions and equipment performance criteria are specified and typical apparatus is illustrated.  
1.2 This test method details the procedures for the production of distillate fractions of standardized quality in the gas oil and lubricating oil range as well as the production of standard residue. In addition, it provides for the determination of standard distillation curves to the highest atmospheric equivalent temperature possible by conventional distillation.  
1.3 The maximum achievable atmospheric equivalent temperature (AET) is dependent upon the heat tolerance of the charge. For most samples, a temperature up to 565 °C (1050 °F) can be attained. This maximum will be significantly lower for heat sensitive samples (for example, heavy residues) and might be somewhat higher for nonheat sensitive samples.  
1.4 The recommended distillation method for crude oils up to cutpoint 400 °C (752 °F) AET is Test Method D2892. This test method can be used for heavy crude oils with initial boiling points greater than 150 °C (302 °F). However, distillation curves and fraction qualities obtained by these methods are not comparable.  
1.5 This test method contains the following annexes:
