ASTM F838-15a 测定液体过滤用膜过滤器细菌滞留的标准试验方法

5.1 This test method is designed to assess the retentivity of a sterilizing filter under standard challenge conditions. 5.1.1 A challenge of 107 bacteria per cm2 of effective filtration area is selected to provide a high degree of assurance that the filter will be challenged uniformly across the membrane surface to assure it will quantitatively retain large numbers of organisms. The model challenge organism, B. diminuta, is widely considered to be a small bacterium and is recognized as an industry standard for qualifying sterilizing filters. Other species may represent a worst-case test in terms of ability to penetrate a filter. This test does not provide assurance that filters can completely retain such bacteria. 5.1.2 The analytical procedure utilized in this test method provides a method to assign a numerical value to the filtration efficiency of the filter being evaluated under standard filtration conditions. For the purpose of product sterility assurance, additional process-specific studies should be performed. 1.1 This test method determines the bacterial retention characteristics of membrane filters for liquid filtration using Brevundimonas diminuta as the challenge organism. This test method may be employed to evaluate any membrane filter system used for liquid sterilization. 1.2 This test method is not intended to be used in performance of product- and process-specific validation of the bacterial retention characteristics of membrane filters to be used in pharmaceutical or biopharmaceutical sterilizing filtration, or both. Process- and product-specific bacterial retention validation should be carried out using the intended product manufacturing process parameters and the product solution or surrogate as the carrier fluid. 1.3 The values stated in SI units are to be regarded as standard. 1.3.1 Exception—The inch-pound values given for units of pressure are to be regarded as standard; SI unit conversions are shown in parentheses. 1.4 This standard may involve hazardous materials, operations, and equipment. 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 Bacterial Retention of Membrane Filters Utilized for Liquid Filtration

ASTM D4412-15 水和水沉积物中硫酸盐还原细菌的标准试验方法

5.1 Sulfate-reducing bacteria are widely distributed in marine and fresh water muds which, in consequence, frequently are laden with the hydrogen sulfide produced by these organisms during dissimilatory sulfate reduction. 5.2 It has been reported that Desulfovibrio spp. can form as much as 10 g of sulfide per litre during active multiplication. Sulfate-reducing bacteria can cause the external or internal corrosion of water or wastewater pipelines and pipelines for petroleum and natural gas. The formation of galvanic cells by massive growth of sulfate-reducing bacteria under suitable conditions makes the corrosion much worse than just the effect of the hydrogen sulfide on the metal or concrete. 1.1 These test methods cover the procedure for the detection and enumeration by the most probable number (MPN) technique of sulfate-reducing bacteria in water or water-formed deposits. 1.2 Two media preparations are provided. Medium A which is prepared with reagent grade water, and Medium B which is prepared using the water to be sampled as the water source. Medium B is offered for those special conditions where sulfate-reducing bacterial strains have adapted to atypical non-fresh water environment. 1.3 For the isolation and enumeration of thermophilic sulfate-reducing bacteria encountered in waters associated with oil and gas production, all broths, dilution blanks, and incubations must be maintained at temperatures of at least 45°C and preferably within 5°C at the sample temperature. 1.4 The sensitivity of these test methods can be increased by purging the dilution blanks and tubes of media with nitrogen immediately prior to use. 1.5 The analyst should be aware that adequate collaborative data for precision and bias statements as required by Practice D2777 are not provided. See Section 11 for details. 1.6 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.7 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.

EN 16421:2014 饮用水中含有物质的影响 微生物生长的增加(EMG)

This European Standard specifies three methods for determining the ability of non-metallic materials to enhance the growth of micro-organisms. This European Standard is applicable to those materials destined to be used under various conditions for the transport and storage of water intended for human consumption. The standard allows for the testing of a single type of material, or a product in which only one material is in contact with water. It is unsuitable for use with assembled products where more than one material is exposed to water. NOTE The results given by each method are not directly comparable.

This part of ISO 9308 specifies a method for the enumeration of Escherichia coli (E. coli) and coliform bacteria. The method is based on membrane filtration, subsequent culture on a chromogenic coliform agar medium, and calculation of the number of target organisms in the sample. Due to the low selectivity of the differential agar medium, background growth can interfere with the reliable enumeration of E. coli and coliform bacteria, for example, in surface waters or shallow well waters. This method is not suitable for these types of water. This part of ISO 9308 is especially suitable for waters with low bacterial numbers that will cause less than 100 total colonies on chromogenic coliform agar (CCA). These may be drinking water, disinfected pool water, or finished water from drinking water treatment plants. Some strains of E. coli which are β-D-glucuronidase negative, such as Escherichia coli O157, will not be detected as E. coli. As they are β-D-galactosidase positive, they will appear as coliform bacteria on this chromogenic agar.

Dieser Teil von ISO 9308 beschreibt ein Verfahren fur die Zahlung von Escherichia coli (E. coli) und coliformen Bakterien. Das Verfahren beruht auf einer Membranfiltration, einer anschliesenden Kultivierung auf dem Chromogenen Coliformen Agar (CCA) und der Berechnung der Anzahl der Zielorganismen in der Probe. Aufgrund der geringen Selektivitat des Agars zur Primaranreicherung kann die Begleitflora eine verlassliche Zahlung von E. coli und coliformen Bakterien storen, z. B. in Oberflachenwassern oder Wasser aus oberflachennahen Brunnen. Dieses Verfahren ist fur solche Wasserarten nicht geeignet. Dieser Teil von ISO 9308 eignet sich besonders fur die Untersuchung von Wassern mit niedrigen Bakterienzahlen, bei denen insgesamt weniger als 100 Kolonien auf dem Chromogenen Coliformen Agar (CCA) wachsen. Dies konnen Trinkwasser, desinfizierte Schwimmbeckenwasser oder fertig aufbereitete Wasser aus Wasseraufbereitungsanlagen sein. Einige E. coli-Stamme, die -D-Glucuronidase-negativ sind, wie z. B. Escherichia coli O157, werden nicht als E. coli bestimmt. Da sie -D-Galactosidase-positiv sind, erscheinen sie als coliforme Bakterien auf einem chromogenen Nahragar.
