1、Designation: D5196 06 (Reapproved 2013)Standard Guide forBio-Applications Grade Water1This standard is issued under the fixed designation D5196; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision. A number in
2、 parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This guide is intended to describe the chemical andbiological characteristics of water to be used whenever criticalpurity is essential to the us
3、e intended in laboratory Bio-Applications, for example, clinical, pharmaceutical, and bio-medical. The importance of such a reagent is often underesti-mated despite the impact that it can have.1.2 This guide is not intended to be used as a reference inpreparing water for injectables. Generally, the
4、appropriate useof this guide may include experiments involving tissue culture,chromatography, mass spectrometry, Polymerase Chain Reac-tion (PCR), DeoxyriboNucleic Acid (DNA) sequencing, DNAhybridization, electrophoresis, molecular biology or analyseswhere molecular concentrations of impurities may
5、be impor-tant.1.3 For all the other applications linked to anASTM methodand not bio-sensitive that require purified water, it is recom-mended that Specification D1193 or Test Method D5127 beconsulted.1.4 This standard does not purport to address all of thesafety concerns, if any, associated with its
6、 use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.

United States15. Composition5.1 Water for Bio-Applications should be prepared
16、 (usingwater purification technologies) starting from water complyingwith the U.S. Environmental Protection Agency (EPA) Na-tional Primary Drinking Water Regulations, or from compa-rable regulations from the European Union or Japan. The use ofsuch a minimum standard quality for feed water is importa
17、nt todecrease the risk of producing and using final purified waterthat would be compliant with the compositions given in Table1 but could contain certain specific contaminants in concen-trations that could affect the applications.5.2 Recommendations for purity of water should conform tothe propertie
18、s and chemical limits given in Table 1; however,the suggested maximum limits and the actual impuritiesconsidered, or both, may be modified by the user based uponthe intended use of the water.5.3 Although these water types and associated grades havebeen defined specifically for use with ASTM Standard
19、s, theymay be appropriate for other applications. It is the responsi-bility of the users of this standard to ensure that the selectedwater types or grades are suitable for their intended use.6. Reagents6.1 Purity of WaterUnless otherwise indicated, referencesto water shall be understood to mean wate
20、r types as defined inthis guide.7. Summary of Preparation Methods7.1 The method of preparation used for the water must bedesigned to remove organic, inorganic, volatile, biologicalimpurities and particulates to provide water that meets theconcentration limits in Table 1. These are suggested limits,s
21、ince the actual maximum levels for the individual impuritieswill depend on the end use for which the water is required.More restrictive limits than those suggested in Table 1 may berequired by mutual consent of the parties concerned, provideda suitable test method is agreed upon.7.2 The Bio-Applicat
22、ions grade water needs to be preparedfrom tap water complying with U.S. EPA National PrimaryDrinking Water regulations or comparable regulations of theEuropean Union or Japan.7.3 The purification of tap water shall be accomplished by asingle technology or a combination of suitable purificationtechno
23、logies such as distillation, deionization,electrodeionization, carbon adsorption, reverse osmosis,ultrafiltration, nanofiltration, UV photo-oxidation, and/orscreen membrane filtration, to meet the compositions given inTable 1.7.4 The water purification systems containing these tech-nologies should b
24、e constructed from materials shown tocontribute to low contamination to the final product water.7.5 Because quality assurance is key to ensure safety,efficiency and reliability, validation of the water purificationinstallation is highly recommended (see Section 14).8.
