GSO ISO 7704:2013 水质 微生物分析中使用的膜过滤器的评估

Abstract Gives a procedure for the evaluation and comparison of water-testing filters intended for the enumeration of specific organisms and mixed microbial populations. The procedure provides general guidelines for comparative testing of the recoveries of bacteria, yeasts and other fungi on membrane filters, as compared to recoveries by the spread plate and pour plate techniques.

GSO ISO 10705-4:2013 水质细菌检测和计数 第4部分脆弱拟杆菌感染细菌计数

This part of ISO 10705 specifies a method for the detection and enumeration of bacteriophages infecting Bacteroides fragilis by incubating the sample with an appropriate host-strain. The method is applicable to all kinds of water, sediments and sludge extracts, where necessary after dilution. In the case of low phage numbers, a preconcentration step may be necessary for which a separate International Standard has been developed. The method is also applicable to shellfish extracts. NOTE It is desirable for International Standards to be adopted as widely as possible. This part of ISO 10705 includes reference to alternative procedures which obviate the need for expensive materials or equipment which may not be readily available in developing countries. Use of these alternatives will not affect the performance of this method.

GSO ISO 10705-1:2013 水质细菌检测和计数 第1部分F型RNA细菌计数

This part of IS0 10705 specifies a method for the detection and enumeration of F-specific ribonucleic acid (RNA) bacteriophages by incubating the sample with an appropriate host strain. The method can be applied to all kinds of water, sediments and sludges, where necessary after dilution. In the case of low numbers, a preconcentration step may be necessary for which a separate part of IS0 10705 will be developed. The method can also be applied to shellfish extracts. Depending on the relative abundance of Fspecific RNA bacteriophages to background organisms, additional confirmatory tests may be necessary and are also specified in this part of IS0 10705. The presence of F-specific RNA bacteriophages in a water sample generally indicates pollution by wastewater contaminated by human or animal faeces. Their survival in the environment, removal by widely used water treatment processes and concentration or retention by shellfish resembles that of foodborne and waterborne human enteric viruses, for example the enteroviruses, hepatitis A virus and rotaviruses.

GSO ISO 15553:2013 水质 水中隐孢子虫和贾第鞭毛虫包囊的分离和鉴定

This International Standard specifies a method that is applicable for the detection and enumeration of Cryptosporidium oocysts and Giardia cysts in water. It is applicable for the examination of surface and ground waters, treated waters, mineral waters, swimming pool and recreational waters. This method does not allow identification to species level, the host species of origin or the determination of viability or infectivity of any Cryptosporidium oocyst or Giardia cyst which may be present. These procedures are for use by experienced analysts who have successfully completed competency tests prior to commencing analysis. In addition, such analysts should continue to demonstrate competency by examining seeded samples at regular intervals and taking part in external quality assurance schemes. NOTE Bodies resembling Cryptosporidium or Giardia in morphology can be present and these may be mistaken for oocysts or cysts. Results should be interpreted with care. Where there is doubt about the identity of oocysts or cysts or where an unusually high result is obtained, it is advisable to have the slides examined by experts from other laboratories to confirm or refute the findings.

GSO ISO 10705-3:2013 水质细菌检测和计数 第3部分水中细菌浓度的验证方法

This part of ISO 10705 specifies the general principles for assessing the performance of methods for the concentration of bacteriophages from water. Concentration is recommended for those water samples expected to contain < 3 pfp (plaque-forming particles) per millilitre. Concentration methods can be applied to all kinds of water provided that the amount and nature of suspended solids and/or dissolved matter do not interfere with the concentration procedure. This part of ISO 10705 does not give specific details of concentration methods, but outlines the fundamental principles for evaluating the suitability of a particular method for a given type and volume of water. Annex A gives examples of methods that have been found satisfactory and their fields of application

ASTM E2783-11 使用时间杀死方法评估水混溶性化合物的抗菌活性的标准测试方法

This procedure may be used to assess the in vitro reduction of a microbial population of test organisms after exposure to a test material.1.1 This test method measures the changes of a population of aerobic and anaerobic microorganisms within a specific sampling time when tested against antimicrobial test materials in vitro. The organisms used are standardized as to growth requirements and inoculum preparation and must grow under the conditions of the test. The primary purpose of this test method is to provide a set of standardized conditions and test organisms to facilitate comparative assessments of antimicrobial materials miscible in aqueous systems. 1.2 This test method allows the option of using a test sample size of 10 mL or 100 mL. 1.3 Knowledge of microbiological techniques is required for this procedure. 1.4 Aseptic technique should be practiced at all times. 1.5 In this test method, SI units are used for all applications, except for distance in which case inches are used and SI units follow in parentheses. 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.
