5.1 This test method is useful for quality-control tests on PVC compounds having a wide range of melt viscosities. Measurements are made at shear rates close to 1 s−1.5.2 In addition to the properties mentioned in Test Method D1238, this technique is sensitive to plasticizer content, polymer molecular weight, polymer stability (both thermally and rheologically), shear instability, and general composition. The sensitivity of the material to temperature necessitates slightly tighter controls than those stated in Test Method D1238.5.3 The sensitivity of this test method makes it useful for correlating with processing conditions and as an aid in predicting changes in processing. However, as a one-point measure of flow relative to shear rate, its one drawback is that the same PVC melt flow values can be obtained for materials having different processibility; the chance of this happening is minimized, however, if the compounds are similar in composition.5.4 Correlations with a wide range of processing conditions have supported the conclusions that little or no change in composition occurs during the test. Thus, this test is able to detect and follow profound changes which occur during extrusion, injection molding, milling, or mixing. These changes are due to three types of measured instability in polymers:5.4.1 Thermal instability due to temperature effect.5.4.2 Shear instability due to breaking of polymer bonds.5.4.3 Rheological instability due to nonuniform distributions of widely different viscosity or molecular weight elements.5.4.4 Thus, implications with respect to PVC molecular structural changes can be detected and predicted.1.1 This test method is an extension of Test Method D1238 specific to the measurement of flow rates of poly(vinyl chloride) (PVC) compounds while detecting and controlling various polymer instabilities associated with the flow rate.1.2 The values stated in SI units are to be regarded as standard. The values given in parentheses are mathematical conversions to inch-pound units that are provided for information only and are not considered 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.NOTE 1: There is no known ISO equivalent to this standard.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.

4.1 Published literature shows that the yield of radiolytic reactions that occur during radiation treatment increases with radiation dose level. Measurement of the products of these reactions can be used as an internal dosimeter.4.2 Trans-vinylene unsaturations are formed during ionization treatment by abstraction of a hydrogen molecule, and to a lesser extent by the recombination of two adjacent alkyl free radicals that reside on the same chain.4.3 Previous work generated calibration curves of trans-vinylene absorption area as a function of absorbed radiation dose, yielding a linear relationship for both gamma- and electron beam-irradiated polyethylene.4.4 This data can be used to determine received dose as a function of position, assuming a calibration curve (TVI versus radiation dose level) is known for the particular material and radiation conditions used, and can be used to determine uniformity of dose level in irradiated polyethylene.1.1 This test method describes the measurement of the number of trans-vinylene groups in ultra-high molecular weight polyethylene (UHMWPE) intended for use in medical implants. The material is analyzed by infrared spectroscopy.1.2 This test method is based on Guide F2102.1.3 The applicability of the infrared method has been demonstrated in other literature reports. This particular method, using the intensity (area) of the C-H absorption centered at 1370 cm-1 to normalize for the sample’s thickness, will be validated by an Interlaboratory Study (ILS) conducted according to Practice E691.1.4 The values stated in SI units are to be regarded as standard.

5.1 The incidental conversion of organic material to trihalomethanes and other volatile organohalides during chlorination of water is a possible health hazard and is the object of much research. This test method can be used as a rapid, simple means for determining many volatile organohalides in raw and processed water.1.1 This test method covers the analysis of drinking water. It is also applicable to many environmental and waste waters when adequate validation is included.1.2 This test method covers the determination of halomethanes, haloethanes, and some related extractable organohalides amenable to gas chromatographic measurement. The applicable concentration range for trihalomethanes is from 1 to 200 μg/L. Detection limits depend on the compound, matrix, and on the characteristics of the gas chromatographic system.1.3 For compounds not specifically included in the precision and bias section the analyst should validate the test method by collecting precision and bias data on actual samples.1.4 Confirmation of component identities is obtained by observing retention times using gas chromatographic columns of different polarities. When concentrations are sufficiently high (>50 μg/L) confirmation with halogen specific detectors or gas chromatography/mass spectrometry (GC/MS) may be used. Confirmation of purgeable compounds at levels down to 1 μg/L can be obtained using Test Method D3871 with GC/MS detection.1.5 The values stated in SI units are to be regarded as standard.

1.1 This practice describes techniques for determining gettering rates, sorption capacity, and gas content of nonevaporable getters in the molecular flow region.1.2 Procedures for activating getters and for determining gas evolution rates are also given.1.3 The various tests described are mostly destructive in nature. In general, the tests are semiquantitative, but they can be expected to yield comparative information on a single laboratory basis. Multilaboratory reproducibility can be established only with round-robin testing. Single laboratory precision is ±15 % for gettering rate and sorption capacity. Multilaboratory reproducibility is estimated at ±50 %. Gas content measurements may have a substantially greater error due to the uncertainty of the temperature.1.4 Adverse getter-device interactions such as contamination and poisoning can occur. Such problems are beyond the scope of this practice. The user and seller should establish criteria for controlling problems such as chemical reactions, loose particles, getter location, etc.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 and health practices and determine the applicability of regulatory limitations prior to use.

5.1 General Utility—The molecular weight (MW) and molecular weight distribution (MWD) are fundamental characteristics of a polymer sample. They are used for a wide variety of correlations for fundamental studies, processing, or product applications. For example, the observed MWD is compared to one predicted from assumed kinetics or mechanisms for a polymerization reaction. Differences between the values will allow alteration of theory or experimental design. Similarly, the strength, melt flow, and other properties of a polymer sample usually are dependent on MW and MWD. Determinations of MW and MWD are used for quality control of polymers.5.2 Limitations—Because of the need for specific calibration of the polymer type under study, and because of the specific nature of polymer/solvent/column-packing interactions, this test method is valid only for polystyrene and non-exclusion effects are to be avoided. However, many of the principles of the method have been applied in generating HPSEC methods for other polymer systems, for example, using the principles of universal calibration. (see Practice D3016).1.1 This test method covers the determination of molecular weight (MW) averages and the distribution of molecular weights for linear, soluble polystyrene by high-performance size-exclusion chromatography (HPSEC). This test method is not absolute and requires the use of commercially available narrow molecular weight distribution (MWD) polystyrene standards for calibration. This test method is applicable for samples containing molecular weight components that have elution volumes falling within the elution volume range defined by polystyrene standards (that is, molecular weights generally from 2000 to 2 000 000 g·mol−1).1.2 The HPSEC is differentiated from traditional size-exclusion chromatography SEC (also referred to as gel permeation chromatography (GPC)) in that the number of theoretical plates per metre with an HPSEC system is at least ten times greater than that for traditional SEC (see Terminology D883 and Practice D3016).2 The HPSEC systems employ low-volume liquid chromatography components and columns packed with relatively small (generally 3 to 20 μm) microporous particles. High-performance liquid chromatography instrumentation and automated data handling systems for data acquisition and processing are required.1.3 The values stated in SI units are to be regarded as the 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. Specific precautionary statements are given in Section 9.NOTE 1: There is no known ISO equivalent to this standard.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.

4.1 The weight-average molecular weight is a fundamental structure parameter of polymers, which is related to many physical properties of the bulk material, such as its rheological behavior. In addition, knowledge of the weight-average molecular weight, together with knowledge of the number-average molecular weight from osmometry, provides a useful measure of the breadth of the molecular-weight distribution.4.2 Other important uses of information on the weight-average molecular weight are correlation with dilute-solution or melt-viscosity measurements and calibration of molecular-weight standards for use in liquid-exclusion (gel-permeation) chromatography.4.3 To the extent that the light-scattering photometer is appropriately calibrated, light scattering is an absolute method and is therefore be applied to nonionic homopolymers that have not previously been synthesized or studied.1.1 This test method describes the test procedures for determining the weight-average molecular weight Mw of polymers by light scattering. It is applicable to all nonionic homopolymers (linear or branched) that dissolve completely without reaction or degradation to form stable solutions. Copolymers and polyelectrolytes are not within its scope. The procedure also allows the determination of the second virial coefficient, A2, which is a measure of polymer-solvent interactions, and the root-mean-square radius of gyration (s2)1/2, which is a measure of the dimensions of the polymer chain.1.2 The molecular-weight range for light scattering is, to some extent, determined by the size of the dissolved polymer molecules and the refractive indices of solvent and polymer. A range frequently stated is 10,000 to 10,000,000, is often extended in either direction with suitable systems and by the use of special techniques.1.2.1 The lower limit to molecular weight results from low levels of excess solution scattering over that of the solvent. The greater the specific refractive increment dn/dc (difference in refractive indices of solution and solvent per unit concentration), the greater the level of solution scattering and the lower the molecular weight that shall be determined with a given precision.1.2.2 The upper limit to molecular weight results from the angular dependence of the solution scattering, which is determined by the molecular size. For sufficiently large molecules, measurements must be made at small scattering angles, which are ultimately outside the range of the photometer used.1.3 The values stated in SI units are to be regarded as 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.NOTE 1: There is no known ISO equivalent to this standard.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.

4.1 This practice summarizes two methods that may be used to precondition UHMWPE by the absorption of lipids to differentiate the simulated in vitro oxidative stability of UHMWPEs, after lipid exposure.4.1.1 Procedure A, High Squalene Absorption—This method of preconditioning with lipids may be used for comparative oxidative stability testing to screen different materials under aggressive conditions.4.1.2 Procedure B, Mixed Lipid Absorption—This method of preconditioning may be used for comparative oxidative stability testing under mild conditions that more closely simulate in-vivo conditions.4.2 This practice may be used to accelerate the oxidation of UHMWPE components when using elevated temperature and elevated oxygen pressure according to the methods of Practice F2003. Under real-time conditions such as implantation, oxidative changes to UHMWPE formulations may take months or years to produce changes that may result in deleterious mechanical performance. The method outlined in this practice permits the preparation of UHMWPE for evaluation of oxidative stability in a relatively short period of time (for example, weeks).4.3 This practice may also be used to precondition UHMWPE test specimens prior to characterization of their physical and chemical properties. In particular, this practice may be used for preconditioning with lipids prior to oxidation induction time (OIT) testing as outlined in Test Method D3895.1.1 It is the intent of this practice to permit an investigator to incorporate lipids found in the synovial environment into polymeric specimens. This can be used as a preconditioning step to evaluate the oxidative stability of ultra-high-molecular-weight polyethylene (UHMWPE) materials. This practice describes a laboratory procedure for preconditioning of UHMWPE specimens.1.2 The preconditioned UHMWPE can be aged at elevated temperature and at elevated oxygen pressure following methods of accelerated aging described in Practice F2003, to accelerate oxidation of the material and thereby allow for the evaluation of its long-term chemical stability.1.3 The preconditioned UHMWPE can be tested without further aging using a method to evaluate oxidative stability such as oxidation induction time as described in Test Method D3895.1.4 The methods of this practice may be used on any type of UHMWPE material intended for use in total joint arthroplasty in a synovial joint (for example, conventional, cross-linked, antioxidant stabilized, etc.). See Appendix X1.1.5 Although the preconditioning method followed by accelerated aging described by this practice will permit an investigator to compare the oxidative stability of different UHMWPE materials, it is recognized that this method is not known to simulate the degradative mechanisms for an implant during real-time shelf aging or in vivo. The described methods have not been evaluated for mechanical testing under cyclic loading.1.6 The preconditioning and accelerated aging methods specified herein are intended to rank the resistance to oxidation of materials as a result of the absorption of lipids, which may occur in UHMWPE following implantation, and to determine susceptibility to oxidative changes. The methods have not been evaluated for use in preconditioning of UHMWPE components for subsequent testing of mechanical or wear properties. Procedure A should not be used for preconditioning of UHMWPE components for subsequent testing of mechanical or wear properties.1.7 The values stated in SI units are to be regarded as standard. The values given in parentheses are mathematical conversions to inch-pound units that are for information only and are not considered standard.1.8 This standard does not purport to address all of the safety concerns, if any, associated with its use.

4.1 Contaminated sites subject to remediation are growing in complexity and associated remediation costs, presenting a challenge for managers of contaminated sites. The need to properly monitor, evaluate, and report remediation processes (including physical, chemical, and biological) characterizing site conditions and contaminant mass and attenuation is critical for the evaluation and selection of effective remediation strategies. Assessment and characterization of biological processes associated with contaminant attenuation is supported and improved by the accurate and consistent use of molecular biological tools (MBTs) including data acquisition, interpretation, and reporting.4.2 The development of this guide through ASTM International is designed to meet the needs of managers of contaminated sites within the United States and elsewhere. The variety of available MBTs and the complexity with which they are currently being applied are not addressed in existing ASTM International Standards. The principal users of this guide should be industry project managers, regulators, consultants, analytical laboratories, and community stakeholders.1.1 This guide provides a framework for the application of molecular biological tools (MBTs) to assess and characterize in-situ biological processes to improve contaminated soil and groundwater management. While the focus of this guide is on in-situ biological processes, some concepts of how to apply MBTs can also be applied to ex-situ bioremediation approaches (for example, biopiles, bioreactors) to support design, operation, and troubleshooting. The intent of this guide is to develop a consistent way in which MBTs are applied at contaminated sites, not to develop expertise. Technical experts need to be engaged whenscoping, planning, executing, and interpreting data for MBTs. Lastly, there is a brief description of isotopic techniques within section 5.2; however, the scope and focus of this guide is the use of nucleic acid-based MBTs to assess biological processes at contaminated sites.1.2 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.1.3 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.

This classification system provides a method of adequately identifying PTFE micropowders using a system consistent with that also of another specific classification. These powders are sometimes known as lubricant powders which usually have a much smaller particle size than those used for molding or extrusion. The test methods and properties included are those required to identify and specify the various types of fluoropolymer micropowders. This classification covers two groups of fluoropolymer micropowders. Fluoropolymer micropowders are classified into groups according to their base fluoropolymer. These groups are further subdivided into classes and grades. Different tests shall be performed in order to determine the following properties of the micropowders: melting characteristics, melt flow rate, specific gravity, water content, particle size, surface area, and bulk density.1.1 This classification system provides a method of adequately identifying low molecular weight polytetrafluoroethylene (PTFE) and fluorinated ethylene propylene (FEP) micronized powders using a system consistent with that of Classification System D4000. It further provides a means for specifying these materials by the use of a simple line callout designation. This classification covers fluoropolymer micronized powders that are used as lubricants and as additives to other materials in order to improve lubricity or to control other characteristics of the base material.1.2 These powders are sometimes known as lubricant powders.
