ASTM G135-95(2019) Standard Guide for Computerized Exchange of Corrosion Data for Metals (Withdrawn 2023) Withdrawn, No replacement 发布日期 :  1970-01-01 实施日期 : 

4.1 This guide establishes a formalism for transferring corrosion test data between computer systems in different laboratories. It will be used by standards developers to specify the format of files containing test results.4.2 This guide defines a generic approach to structuring data files. It will be used by software developers to create programs which read and write these files.4.3 Each standard test procedure will define a unique data file derived from this guide. Each time a standard test is performed, the results can be summarized in a data file specific to that test.4.4 Some experimental information will be global, that is, common to several standards, and will be contained in Guide G107 and other global data dictionaries. Other information will be local, that is, unique to a given standard, and will be defined in that standard.1.1 This guide covers the techniques used to encode corrosion of metals test results for exchange between computer systems.1.2 Guidelines are given for creating a data exchange appendix for each ASTM corrosion of metals standard.1.3 Instructions are given for creating data translation software from the contents of the data exchange appendix.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.

One of the major factors in the unsatisfactory performance of anion exchange resins is their fouling by organic material. Knowledge of the degree of fouling can be used to assess the condition of the resin and may indicate the need for pretreatment of the influent, remedial cleaning procedures, or resin replacement.It is recognized that this test method may not remove and detect cation sloughage products or declumping agents. It is not intended to remove all organic compounds from the resin.Since the chemical structures of organics compounds fouling the resin are generally unknown and are expressed only on the basis of their carbon content, interpretation of test results to form a basis for predictions for resin performance or cleaning procedures should be approached with caution.Samples may be taken before or after plant regeneration, or both, depending on the type of information desired. This decision is left to the judgment of the user.1.1 This test method provides a general estimate of the organic fouling of an anion exchange resin based upon total organic carbon measurements.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. For a specific hazard statement, see 8.3.

4.1 The salt removal capacity of a powdered resin precoat is limited by the capacity of either the anion-exchange resin or the cation-exchange resin contained in it. Applications include condensate polishing in fossil-fueled electric generating plants, as well as condensate polishing, spent fuel pool water treatment, reactor water treatment, and low-level radioactive liquid waste treatment in nuclear-powered electric generating plants.4.2 By determining the ion-exchange capacity profile of either a cation exchange resin or an anion-exchange resin (capacity expended per unit of time under specific conditions), it is possible to estimate runlength and remaining capacity when treating a liquid of the same makeup. Although they cannot accurately predict performance during condenser leaks, these test methods are useful for determining operating capacities as measured under the test conditions used.4.3 These test methods may be used to monitor the performance of either powdered anion-exchange resin or powdered cation-exchange resin. The total capacity of either resin depends primarily upon the number density of ion-exchange sites within the resin. The operating capacity is a function of the total capacity, degree of conversion to the desired ionic form when received, and properties of the resin and the system that affect ion exchange kinetics.1.1 These test methods cover the determination of the operating ion-exchange capacity of both powdered cation-exchange resins (hydrogen form) and powdered anion-exchange resins (hydroxide form). These test methods are intended for use in testing new powdered ion-exchange resins when used for the treatment of water. The following two test methods are included:  SectionsTest Method A—Operating Capacity, Anion-Exchange  Resin, Hydroxide Form 7 to 15Test Method B—Operating Capacity, Cation-Exchange  Resin, Hydrogen Form 16 to 241.2 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.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.

5.1 This test method is applicable to the analysis of new materials that are sold as mixtures and to samples taken from regenerable units containing mixtures of anion-exchanging and cation-exchanging materials. It is used to determine the ratio of the components without separating them from each other.5.2 This test method is intended for mixtures of ion-exchange materials that have salt-splitting capacity as measured by Test Method E of Test Methods and Practices D2187 for cation-exchange resins, and Test Method H for anion-exchange resins. In the case of cation-exchange resins, these are styrene-based polymers with sulfonic acid functional groups. The anion-exchanging materials in this class are styrene-based materials with quaternary ammonium functional groups. The test method will determine the amount of anion-exchange material of any functionality present in the mixture. However, when anionic groups that are not salt-splitting are present, the values for cationic groups will be high due to the acidic character of the anion effluent. Cationic groups that do not split salts are not measured.5.3 Samples are analyzed in this test method as received. It is not necessary that the cation-exchanging resin be in the hydrogen form and the anion-exchanging resin be in the hydroxide form for this test method.5.4 This test method may be used to determine if new materials are balanced to meet their specification values. In operating regenerable units, it may be used to determine if the components are separating properly or remixing properly. It may also be used to check for improper balance in bedding or for loss of a component during operation.5.5 This test method begins with the conversion to the hydrogen and chloride forms. However, it may be combined with the determination of the residual chloride and sulfate sites by elution with sodium nitrate as described in Test Methods J and L in Test Methods and Practices D2187. In such cases the hydrogen ion as well as the chloride ion is determined in the second sodium nitrate elution described in Test Method I of Test Methods and Practices D2187, and the calculations given herein are made using the titration values so determined.1.1 This test method determines the ratio between the equivalents of anion-exchange capacity and the equivalents of cation-exchange capacity present in a physical mixture of salt-splitting anion-exchange material and salt-splitting cation-exchange material.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.

5.1 This guide recommends practices and solutions for global supply chain information exchange for substances, preparations, and articles as identified by REACH. The first five annexes of REACH guidance standards serve as a central repository for REACH industry guidance that spans industry sectors and facilitates collaboration across complex global supply chains. Annexes 6-9 provide key EU guidance on information exchange in the supply chain.5.2 Section 6 outlines the information that is to be exchanged in the supply chain both in the upstream and downstream directions.1.1 This guide will assist companies that manufacture, buy, or sell, or both, substances, preparations, and articles to ensure that supply chains comply with the European Union’s Registration, Evaluation, and Authorization of Chemicals (REACH) regulation. This is accomplished by identifying the specific information elements that must be specified, requested and exchanged in communication between actors in the supply chain.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.

5.1 This practice will be used most frequently to sample materials as received from the manufacturer in the original shipping container and prior to any resin-conditioning procedure. Since certain ion-exchange materials are supplied by the manufacturer in the dry or free-flowing state whereas others are supplied moist, it is necessary to employ two different sampling devices. Therefore, this practice is divided into Sampling Procedure—Dry or Free-Flowing Material (Section 8), and Sampling Procedure—Moist Material (Section 9).5.2 Once the sample is obtained, it is necessary to protect the ion-exchange materials from changes. Samples should be placed in sealable, gasproof containers immediately.1.1 These practices2 cover procedures for obtaining representative samples of ion-exchange materials. The following practices are included:  SectionsPractice A—Sampling from a Single Package and Multiple Package Lots or Shipments  4 to 11Practice B—Sampling from Fixed Bed Ion-Exchange Equipment Having Unrestricted Head Room  12 to 16Practice C—Sampling from Fixed Bed Ion-Exchange Equipment Having Restricted Head Room  17 to 211.2 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 and health practices and determine the applicability of regulatory limitations prior to use.

ASTM F1221-89(2022) Standard Guide for Interagency Information Exchange Active 发布日期 :  1970-01-01 实施日期 : 

4.1 This guide has been developed to facilitate communications between agencies involved in the delivery of emergency medical services. This guide is intended to be applied by agencies providing emergency medical services to improve their communications with EMS support agencies. It recommends necessary communication before, during, and after an EMS event.1.1 This guide covers the planning, operations, and evaluation phases of interagency communications as part of a comprehensive EMS system.1.2 This is a guide for interagency communications within an EMS system. Interagency communications involves the EMS responder and support agencies whose primary mission is not to deliver prehospital emergency medical care.1.3 The primary focus of this guide is to address interagency communications necessary for ongoing EMS responses.1.4 The guide also addresses interagency communications in any major EMS incident, including man-made or natural disasters.1.5 The recommendations for drills/exercises for the evaluation of interagency communications during an EMS event are also incorporated into this guide.1.6 Additional information can be found in Guide F1220 and Refs (1-5).21.7 The sections in this guide appear in the following sequence:  SectionIntroduction   1Referenced Documents 2Terminology 3 4Procedure 5Rationale Appendix X1Keywords 6References  1.8 This standard does not purport to address all of the safety concerns, if any, associated with its use.

5.1 Uranium and plutonium are used in nuclear reactor fuel and must be analyzed to ensure that they meet acceptance criteria for isotopic composition as described in Specifications C833 and C1008. The criteria are set by mutual agreement between the manufacturer and end user (or between buyer and seller). This standard practice is used to separate chemically the isobaric interferences from 238U and 238Pu and from 241Am and 241Pu, and from other impurities prior to isotopic abundance determination by TIMS.5.2 In facilities where perchloric acid use is authorized, the separation in Test Method C698 may be used prior to isotopic abundance determination. Uranium and plutonium content as well as isotopic abundances using TIMS can be determined by using this separation practice and by following Test Methods C698, C1625, or C1672.1.1 This practice is an alternative to Practice C1411 for the ion exchange separation in small mass samples (~5 μg of plutonium and up to 0.5 mg of uranium in 1 mL of solution) of uranium and plutonium from each other and from other impurities for subsequent isotopic abundance and content analysis by thermal ionization mass spectrometry (TIMS). In addition to being adapted to smaller sample sizes, this practice also avoids the use of hydrochloric acid (HCl) and hydrofluoric acid (HF) and does not require the use of two anion exchange columns as required in Practice C1411.1.2 In chemically unseparated samples isobaric nuclides at mass 238 (238U and 238Pu), and mass 241 (241Pu and 241Am) will be measured together thus compromising the accuracy of the results of isotopic composition of Pu. Therefore, chemical separation of elements is essential prior to isotopic analyses. Concentrations and volumes given in the paragraphs below can be modified for larger sample sizes, different types of anion exchange resin, etc.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 and health practices and determine the applicability of regulatory limitations prior to use.

5.1 This test method can be a useful diagnostic tool in measuring the impurities and detecting their sources in high purity water, boiler feed water and steam condensate of high pressure power plants, and in the process water of certain industries requiring high purity water. 5.2 The measurement of such impurities is most important to these industries since plant outages or product contamination can result from events such as condenser leakage. Also, water quality deviations can occur from condensate polishing and makeup water equipment malfunctions. 5.3 The continuous measurement and trends provided by this test method are of particular interest and can indicate the need for corrections in water treating or operating procedures and equipment. The equipment for this test method can be considered more rugged and adaptable to installation under plant operating conditions than the more accurate laboratory methods, such as ion chromatography and atomic absorption. 1.1 This on-line test method includes hydrogen exchange and degassing by heating or gas stripping and provides means for determining anions (such as Cl−, SO4—, NO3−, and F−) at levels as low as 2 μg/L (2 ppb) and carbon dioxide at the level of 0.01 to 10 mg/L (ppm) at 25°C in high purity water and in steam and water samples in power plants by measuring electrical conductivity. 1.2 The conductivity of all anions (except OH−) is determined and not the conductivity of an individual anion if more than one is present. If only one anion is present (such as Cl− or SO4—−), reference to Section 4, Table 1 and Table 2 or Figs. 1-3 provides the chloride or sulfate and CO2 concentration. 1.3 This test method has been improved in accuracy by using a modern microprocessor instrument for conductivity and temperature measurement and appropriate temperature compensation algorithms for compensation, by using final sample cooling to 25°C, or both. 1.4 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the 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 and health practices and determine the applicability of regulatory limitations prior to use.

5.1 This test method can be used for evaluating performance of commercially available anion-exchange materials regardless of the basic strength of the ion exchange groups. When previous operating history is known, a good interpretation of resin fouling or malfunction can be obtained by comparison against a reference sample of unused ion-exchange material evaluated in the same way.5.2 While resistivity has been chosen as the preferred analytical method for defining the exhaustion end point, with titration as the alternative, it is understood that observation of pH during rinse and the service run can yield useful information. The variations in pH observed with an ion exchange material suspected of having degraded, can be helpful in interpretation of performance when compared with similar data for a reference sample of unused material exhausted in the same way.1.1 This test method covers the determination of the operating capacity of anion-exchange materials when used for the removal of hydrochloric and sulfuric acid from water. It is designed to simulate operating conditions for strong acid removal and is intended for use in testing both new and used materials.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.
