ASTM D6855-17 用静态法测定5NTU下浊度的标准试验方法

5.1 Turbidity is undesirable in drinking water, plant effluent waters, water for food and beverage processing, and for a large number of other water-dependent manufacturing processes. Removal is often accomplished by coagulation, settling, and filtration. Measurement of turbidity provides a rapid means of process control for when, how, and to what extent the water must be treated to meet specifications. 5.2 This test method is suitable to turbidity such as that found in drinking water, process water, and high purity industrial water. 5.3 When reporting the measured result, appropriate units should also be reported. The units are reflective of the technology used to generate the result, and if necessary, provide more adequate comparison to historical data sets. 5.3.1 Table 1 describes technologies and reporting results (see also Refs (1-3)6). Those technologies listed are appropriate for the range of measurement prescribed in this test method. Others may come available in the future. Fig. X5.1 provides a flow chart to aid in selection of the appropriate technology for low-level static turbidity applications. 5.3.2 If a design that falls outside of the criteria listed in Table 1 is used, the turbidity should be reported in turbidity units (TU) with a subscripted wavelength value to characterize the light source that was used. 1.1 This test method covers the static determination of turbidity in water (see 4.1). 1.2 This test method is applicable to the measurement of turbidities under 5.0 nephelometric turbidity units (NTU). 1.3 This test method was tested on municipal drinking water, ultra-pure water, and low turbidity samples. It is the users responsibility to ensure the validity of this test method for waters of untested matrices. 1.4 This test method uses calibration standards are defined in NTU values, but other assigned turbidity units are assumed to be equivalent. 1.5 This test method assigns traceable reporting units to the type of respective technology that was used to perform the measurement. Units are numerically equivalent with respect to the calibration standard. For example, a 1.0 NTU formazin standard is also equal to a 1.0 FNU standard, a 1.0 FNRU standard, and so forth. 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, health, and environmen......

ASTM E3131-17 可疑可见粉末细菌病原体筛查用核酸系统的标准规格

1.1 General:  1.1.1 This specification provides system designers, manufacturers, integrators, procurement personnel, end users/practitioners, and responsible authorities a common set of parameters to match the capabilities of biological assessment tools with user needs. 1.1.2 This specification is not meant to provide for all uses. Manufacturers, purchasers, and end users will need to determine specific requirements including, but not limited to, use by hazardous material (HAZMAT) teams and Urban Search and Rescue (US&R) teams, use in explosive or other hazardous environments or atmospheres, use with personal protective equipment (PPE), use by firefighters or law enforcement officers or both, special electromagnetic compatibility needs, extended storage periods, and extended mission time. These specific requirements may or may not be generally applicable to all nucleic acid-based detection systems. 1.2 Operational Concepts—Nucleic acid-based detection systems are used to detect, identify, or quantify, or combinations thereof, biological hazards to support short-term tactical decision making to protect responders and the public. The system should provide low false-positive and false-negative rates. Uses of these systems include survey, surveillance, and screening of samples, particularly during a response to a suspected biological agent incident. A field-deployable system should withstand the rigors associated with uses including, but not limited to, high- and low-temperatures and storage conditions, shock and vibration, radio frequency interference, and rapid changes in operating temperature and humidity. Note that this specification does not address testing the potential impact of the rigors associated with use of systems in the field. 1.3 Nucleic Acid-Based System Detection Capabilities—Manufacturers or independent third-party testing entities shall document and verify, through testing, the capabilities of the system. 1.4 Units—The values stated in SI units are to be regarded as the standard. No other units of measurement are included in this standard. Liquid concentrations of the biohazard materials are presented in number of biological agents or genome equivalents per volume for pathogens such as bacteria and spores (biological agents/mL, genome equivalents/mL (GE/mL), colony forming units/mL (CFU/mL), or spores/mL). 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.6 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) Comm
