ASTM D3609-00 使用渗透管的校准技术标准实施规范

1.1 This practice describes a means for utilizing permeation tubes for dynamically calibrating instruments, analyzers, and analytical procedures used in measuring concentrations of gases or vapors in atmospheres (1, 2). 1.2 Typical materials that may be sealed in permeation tubes include: sulfur dioxide, nitrogen dioxide, hydrogen sulfide, chlorine, ammonia, propane, and butane (1). 1.3 The values stated in SI units are to be regarded as the 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.

ASTM D3609-00(2005) 使用渗透管的校准技术标准实施规范

Most analytical methods used in air pollutant measurements are comparative in nature and require calibration or standardization, or both, often with known blends of the gas of interest. Since many of the important air pollutants are reactive and unstable, it is difficult to store them as standard mixtures of known concentration for extended calibration purposes. An alternative is to prepare dynamically standard blends as required. This procedure is simplified if a constant source of the gas of interest can be provided. Permeation tubes provide this constant source, if properly calibrated and if maintained at constant temperature. Permeation tubes have been specified as reference calibration sources, for certain analytical procedures, by the Environmental Protection Agency (3). Note8212;This system has the advantage of smaller uncertainty of the temperature of the permeation tube.

ASTM D6512-00 实验室间数值预测的标准规程

1.1 This practice establishes a uniform standard for computing the interlaboratory quantitation estimate associated with Z % relative standard deviation (referred to herein as IQEZ %), and provides guidance concerning the appropriate use and application.1.2 IQEZ % is computed to be the lowest concentration for which a single measurement from a laboratory selected from the population of qualified laboratories represented in an interlaboratory study will have an estimated Z % relative standard deviation (Z % RSD, based on interlaboratory standard deviation), where Z is typically an integer multiple of 10, such as 10, 20, or 30, but Z can be less than 10. The IQE10 % is consistent with the quantitation approaches of Currie () and Oppenheimer, et al ().1.3 The fundamental assumption of the collaborative study is that the media tested, the concentrations tested, and the protocol followed in the study provide a representative and fair evaluation of the scope and applicability of the test method as written. Properly applied, the IQE procedure ensures that the IQE has the following properties:1.3.1 Routinely Achievable IQE ValueMost laboratories are able to attain the IQE quantitation performance in routine analyses, using a standard measurement system, at reasonable cost. This property is needed for a quantitation limit to be feasible in practical situations. Representative laboratories must be included in the data to calculate the IQE.1.3.2 Accounting for Routine Sources of ErrorThe IQE should realistically include sources of bias and variation that are common to the measurement process. These sources include, but are not limited to: intrinsic instrument noise, some "typical" amount of carryover error; plus differences in laboratories, analysts, sample preparation, and instruments.1.3.3 Avoidable Sources of Error ExcludedThe IQE should realistically exclude avoidable sources of bias and variation; that is, those sources that can reasonably be avoided in routine field measurements. Avoidable sources would include, but are not limited to: modifications to the sample; modifications to the measurement procedure; modifications to the measurement equipment of the validated method, and gross and easily discernible transcription errors, provided there was a way to detect and either correct or eliminate them.1.4 The IQE applies to measurement methods for which calibration error is minor relative to other sources, such as when the dominant source of variation is one of the following:1.4.1 Sample Preparationand calibration standards do not have to go through sample preparation.1.4.2 Differences in Analystsand analysts have little opportunity to affect calibration results (as is the case with automated calibration).1.4.3 Differences in Laboratories(for whatever reasons), perhaps difficult to identify and eliminate.1.4.4 Differences in Instruments(measurement equipment), such as differences in manufacturer, model, hardware, electronics, sampling rate, chemical processing rate, integration time, software algorithms, internal signal processing and thresholds, effective sample volume, and contamination level.1.5 Data Quality ObjectivesTypically, one would compute the lowest % RSD possible for any given dataset for a particular method. Thus, if possible, IQE10 % would be computed. If the data indicated that the method was too noisy, one might have to compute instead IQE20 %, or possibly IQE 30 %. In any case, an IQE with a higher % RSD level (such as IQE50 %) would not be considered, though an IQE with RSD 10 % (such as IQE1 %) would be acceptable. The appropriate level of % RSD may depend on the intended use of the IQE.

ASTM F2059-00 用螺旋形瓶测定实验室漏油分散剂效果的标准试验方法

1.1 This test method covers the procedure to determine the effectiveness of oil spill dispersants on various oils in the laboratory. This test method is not applicable to other chemical agents nor to the use of such products or dispersants in open waters.1.2 This test method covers the use of the swirling flask test apparatus and does not cover other apparatuses nor are the analytical procedures described in this report directly applicable to such procedures.1.3 The test results obtained using this test method are effectiveness values that should be cited as test values derived from this standard test. Effectiveness values do not directly relate to effectiveness at sea or in other apparatuses. Actual effectiveness at sea is dependant on sea energy, oil state, temperature, salinity, actual dispersant dosage, and amount of dispersant that enters the oil.1.4 The test results obtained using this test method are intended to provide baseline effectiveness values used to compare dispersants and oil types under conditions analogous to those used in the test.1.5 The decision to use or not use a dispersant on an oil should not be based solely on this or other laboratory test method.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.

BS EN ISO 14644-1:1999 洁净室和相关的控制环境.空气清洁度的分级

This part of ISO 14644 covers the classification of air cleanli-ness in cleanrooms and associated controlled environments exclusively in terms of concentration of airborne particles. Only particle populations having cumulative distributions based on threshold (lower limit) sizes ranging from 0,1 μm to 5 μm are considered for classification purposes. This part of ISO 14644 does not provide for classification of particle populations that are outside of the specified particle size range, 0,1 μm to 5 μm. Concentrations of ultrafine particles (particles smaller than 0,1 μm) and macroparticles (particles largerthan 5 μm) may be used to quantify these populations in terms of U descriptors and M descriptors, respectively. This part of ISO 14644 cannot be used to characterize the physical, chemical, radiological, or viable nature of airborne particles. NOTE The actual distribution of particle concentrations within incre-mental size ranges normally is not predictable and typically is variable over time.
