VDI 3491 Blatt 1-2016 粒子测量测试气溶胶的产生方法原理和概述

This standard describes the principles of the methods for the preparation of test aerosols which can be used for calibration, adjustment and check of particle counting instruments and for checking the associated sampling, conditioning and dilution systems. Further applications for test aerosols are, for example, filter testing, test materials and standardised samples for chemical analysis methods and medical purposes.

ISO 11665-11:2016 环境中放射性的测量 - 空气:氡-222 - 第11部分:深度采样的土壤气体测试方法

This part of ISO 11665 describes radon-222 test methods for soil gas using passive and active in-situ sampling at depth comprised between surface and 2 m. This part of ISO 11665 gives general requirements for the sampling techniques, either passive or active and grab or continuous, for in-situ radon-222 activity concentrations measurement in soil gas. The radon-222 activity concentration in the soil can be measured by spot or continuous measurement methods (see ISO 11665-1). In case of spot measurement methods (ISO 11665-6), the soil gas sampling is active only. On the other hand, the continuous methods (ISO 11665-5) are typically associated with passive soil gas sampling. The measurement methods are applicable to all types of soil and are determined according to the end use of the measurement results (phenomenological observation, definition or verification of mitigation techniques, etc.) taking into account the expected level of the radon-222 activity concentration. These measurement methods are applicable to soil gas samples with radon activity concentrations greater than 100 Bq/m3. NOTE This part of ISO 11665 is complementary with ISO 11665-7 for characterization of the radon soil potential.

VDI 3957 Blatt 2-2016 空气污染物对植物影响的测定和评估的生物测量技术（生物监测）标准化草暴露法

Air pollution can cause accumulation of substances in plants. The assessment of such accumulation shows deposition-related inputs into ecosystems and may indicate risks for plants, animals and humans. In many cases, grass cultures (Lolium multiflorum) are used as plant accumulation indicators. The standard describes the range of use and practical steps of the method of the standardised grass exposure. The individual steps from cultivation, exposure, sampling and sample handling are presented. In addition, the standard user gets information and operational recommendations regarding quality assurance, performance characteristics, presentation of measured data and assessment.

ASTM D7036-16 空气排放试验机构的能力的标准实施规程

4.1 This Practice establishes general criteria for a Quality System that, when followed, helps ensure consistently acceptable data quality from an AETB. The relevant criteria contained in this Practice shall be addressed in the AETB’s Quality Manual, which shall contain or refer to additional specific criteria and requirements where relevant and necessary. The Quality Manual and its implementation (including test protocols, reports, and personnel testing) shall provide the sole basis for determining the conformance of the AETB with this standard. Note 3: This Practice assesses the overall ability of an AETB to deliver data of known and documented quality on a consistent basis regardless of the test method used. There is no requirement to define a scope of testing. It is a requirement of this Practice that prior to performing a test method for the first time, the AETB has in place resources, training, and QA/QC consistent with this Practice to insure data of acceptable quality are produced. 4.2 This Practice is for use by AETBs in developing the quality, administrative, and technical systems that govern their operations. Clients, regulatory authorities, and accreditation bodies may also use it in confirming or recognizing the competency of AETBs. Note 4: This Practice is performance-based; that is, it focuses on the actual performance (in other words, consistent generation of data of known and documented quality) of the AETB rather than on an extensive collection of prescriptive criteria that may or may not be relevant to a particular AETB. It also focuses on the education and qualifications of the individual tester. Note 5: There has been an effort in the development of this Practice to keep the paperwork and administrative burdens on affected AETBs to the minimum required for an effective program. 1.1 This Practice specifies the general requirements for the competence to carry out sampling and analysis for air emissions tests of stationary sources. It covers testing and calibration performed using standard methods, non-standard methods and methods developed by the AETB. 1.2 This Practice is applicable to all bodies engaged in air emission testing regardless of the number of personnel or the scope of testing activities. When an AETB does not undertake one or more of the activities covered by the Practice such as developing test methods, the requirements of those clauses do not apply. 1.3 The notes given provide clarification of text, examples, and guidance. The notes do not contain requirements and do not form an integral part of this Practice. Note 1: ISO/IEC 17025:2005 has been considered when elaborating this Practice. Several, but not all, statements of this Practice are consistent with ISO/IEC 17025:2005.

ASTM E1332-16 室外-室内声音衰减评级的标准分类

4.1 This classification provides a single number rating for transmission loss or noise reduction data that have been measured or calculated. This rating is based on the difference between the overall A-weighted sound level of the sound spectrum given in Table 1 and the overall A-weighted sound level of the spectrum that results from arithmetically subtracting the transmission loss or noise reduction data from this spectrum. The spectrum shape is an average of three spectra from transportation sources (aircraft takeoff, road, and diesel locomotive passby). A study showed that this classification correlated well with the A-weighted and loudness reductions (see ISO 532) calculated for each of the individual spectra used in developing the rating for the one-third octave band range of 50 to 5000 Hz. The calculated numeric value of the rating is based on the sound transmission loss or noise reduction values for a particular specimen and depends only on that data and the shape of the reference source spectrum used in the calculation. The values shown in Table 1 have an arbitrary reference level. Single-number ratings should always be used with caution. Specimens having the same rating can result in different indoor spectra depending on the variation of their transmission loss with frequency. Also, if the actual spectrum of the outdoor sound is different from that assumed in Table 1, the overall A-weighted outdoor-indoor noise reduction may be different from the OINIC. The strong low-frequency content of the spectrum in Table 1 means that specimen achieving a high rating must have strong low-frequency transmission loss. Use of this classification with the spectrum in Table 1 in situations where the source does not have a spectrum similar to Table 1 could result in requirements for more low-frequency transmission loss than is necessary for the application. Examples where this can occur are stage 3 jet aircraft, high-speed freeways with sound dominated by tire noise, and train passbys with sound dominated by horns.6 4.2 This classification requires sound transmission loss (TL), apparent outdoor-indoor transmission loss (AOITL(θ)), or outdoor-indoor noise reduction (OINR(θ)) data in one-third octave bands from 80 to 4000 Hz. Due to accuracy limitations given in Test Method E90 and Guide E966, measurements below the 100 Hz one-third octave band are not usually reported. Studies have shown that data in the 80 Hz one-third octave band are necessary to obtain acceptable correlations for transportation sound sources. For the purposes of this classification, measurements in the 80 Hz one-third octave band are deemed to be of acceptable accuracy. 4.3 Users of this classification should recognize that low frequency measurements of sound transmission loss may be affected by the test specimen size or the specimen edge restraints, or both, particularly for small modular specimens such as doors or windows. Consequently, the outdoor-indoor transmission class (OITC) may also be affected by these factors, resulting in some uncertainty of the field performance of assemblies bearing a rating number using this classification, but to what extent is unknown.
