This European Standard describes a standard method for determining the PM10 or PM2,5 mass concentrations of suspendedparticulate matter in ambient air by sampling the particulate matter on filters and weighing them by means of a balance. Measurements are performed with samplers with inlet designs as specified in Annex A, operating at a nominal flow rate of 2,3 m3/h,over a nominal sampling period of 24 h. Measurement results are expressed in μg/m3, where the volume of air is the volume atambient conditions near the inlet at the time of sampling. The range of application of this European Standard is for 24 h measurements from approximately 1 μg/m3 (i.e. the limit of detection ofthe standard measurement method expressed as its uncertainty) up to 150 μg/m3 for PM10 and 120 μg/m3 for PM2,5. This European Standard describes procedures and gives requirements for the testing and use of so-called sequential samplers,equipped with a filter changer, suitable for extended stand-alone operation. Sequential samplers are commonly used throughout theEuropean Union for the measurement of concentrations in ambient air of PM10 or PM2,5. However, this European Standard does notexclude the use of single-filter samplers. This European Standard represents an evolution of earlier European Standards (EN 12341:1998 and 2014, EN 14907:2005). Newequipment procured shall comply fully with this European Standard. Older versions of these samplers, including those described in EN 12341:2014 Annex B, have a special status in terms of their use. These samplers can still be used for monitoring purposes and for ongoing quality control, provided that a well justified additionalallowance is made to their uncertainties This European Standard also provides guidance for the selection and testing of filters with the aim of reducing the measurementuncertainty of the results obtained when applying this European Standard.

1.1 This test method describes the procedures to determine the opacity of a plume, using digital imagery and associated hardware and software. The aforementioned plume is caused by particulate matter emitted from a stationary point source in the outdoor ambient environment. 1.2 The opacity of emissions is determined by the application of a Digital Camera Opacity Technique (DCOT) that consists of a Digital Still Camera, Analysis Software, and the Output Function’s content to obtain and interpret digital images to determine and report plume opacity. 1.3 This method is suitable to determine the opacity of plumes from zero (0) percent to one hundred (100) percent. 1.4 Conditions that shall be considered when using this method to obtain the digital image of the plume include the plume’s background, the existence of condensed water in the plume, orientation of the Digital Still Camera to the plume and the sun (see Section 8). 1.5 This standard describes the procedures to certify the DCOT, hardware, software, and method to determine the opacity of the plumes. 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 environmental practices and determine the applicability of regulatory limitations prior to use. 1.7 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) Committee.

1.1 This practice is intended to assist in the selection of sorbents and procedures for the sampling and analysis of ambient (1),2 indoor (2), and workplace (3, 4) atmospheres for a variety of common volatile organic compounds (VOCs). It may also be used for measuring emissions from materials in small or full scale environmental chambers or for human exposure assessment. 1.2 This practice is based on the sorption of VOCs from air onto selected sorbents or combinations of sorbents. Sampled air is either drawn through a tube containing one or a series of sorbents (pumped sampling) or allowed to diffuse, under controlled conditions, onto the sorbent surface at the sampling end of the tube (diffusive or passive sampling). The sorbed VOCs are subsequently recovered by thermal desorption and analyzed by capillary gas chromatography. 1.3 This practice applies to three basic types of samplers that are compatible with thermal desorption: (1) pumped sorbent tubes containing one or more sorbents; (2) axial passive (diffusive) samplers (typically of the same physical dimensions as standard pumped sorbent tubes and containing only one sorbent); and (3) radial passive (diffusive) samplers. 1.4 This practice recommends a number of sorbents that can be packed in sorbent tubes for use in the sampling of vapor-phase organic chemicals; including volatile and semivolatile organic compounds which, generally speaking, boil in the range 0 °C to 400 °C (v.p. 15 kPa to 0.01 kPa at 25 °C). 1.5 This practice can be used for the measurement of airborne vapors of these organic compounds over a wide concentration range. 1.5.1 With pumped sampling, this practice can be used for the speciated measurement of airborne vapors of VOCs in a concentration range of approximately 0.1 µg/m3 to 1 g/m3 , for individual organic compounds in 1 L to 10 L air samples. Quantitative measurements are possible when using validated procedures with appropriate quality control measures. 1.5.2 With axial diffusive sampling, this practice is valid for the speciated measurement of airborne vapors of volatile organic compounds in a concentration range of approximately 100 µg/m3 to 100 mg/m3 for individual organic compounds for an exposure time of 8 h or 1 µg/m3 to 1 mg/m3 for individual organic compounds for an exposure time of four weeks. 1.5.3 With radial diffusive sampling, this practice is valid for the measurement of airborne vapors of volatile organic compounds in a concentration range of approximately 5 µg/m3 to 5 mg/m3 for individual organic compounds for exposure times of one to six hours. 1.5.4 The upper limit of the useful range is almost always set by the linear dynamic range of the gas chromatograph column and detector, or by the sample splitting capability of the analytical instrumentation used. 1.5.5 The lower limit of the useful range depends on the noise level of the detector and on blank levels of analyte or interfering artifacts (or both) on the sorbent tubes. 1.6 This procedure can be used for personal and fixed location sampling. It cannot be used to measure instantaneous or short-term fluctuations in concentration. Alternative ‘grab sampling’ procedures using canister air samplers (for example, Test Method D5466) may be suitable for monitoring instantaneous or short term fluctuations in air concentration. Alternatives for on-site measurement include, but are not limited to, gas chromatography, real-time mass spectrometry detectors and infrared spectrometry. 1.7 The sampling method gives a time-weighted average result. 1.8 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1 This practice is under the jurisdiction of ASTM Committee D22 on Air Quality and is the direct responsibility of Subcommittee D22.05 on Indoor Air.

1.1 The purpose of this practice is to describe procedures for the collection of airborne fungal spores or fragments, or both, using inertial impaction sampling techniques. 1.2 This practice is not intended to limit the user from the collection of other airborne particulates that may be of interest and captured through this technique. 1.3 This practice presumes that the user has a fundamental understanding of field investigative techniques related to the scientific process, and sampling plan development and implementation. It is important to establish the related hypothesis to be tested and the supporting analytical methodology needed in order to identify the sampling media to be used and the laboratory conditions for analysis. 1.4 This practice does not address the development of a formal hypothesis or the establishment of appropriate and defensible investigation and sampling objectives. It is presumed the investigator has the experience and knowledge base to address these issues. 1.5 This practice does not provide the user sufficient information to allow for interpretation of the analytical results from sample collection. It is the user’s responsibility to seek or obtain the information and knowledge necessary to interpret the sample results reported by the laboratory. 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.8 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) Committee.
