32、rganismen und Zellkulturen HEPA high efficiency particulate aerosol EN 14583:2004 (E) 7 NCTC National Collection of Type Cultures RH relative humidity T temperature 5 Requirements 5.1 General Performance requirements for volumetric sampling pumps shall comply with EN 1232 for low flow rate pumps or
33、EN 12919 for high flow rate pumps. This shall apply both to integral and separate pumps. 5.2 Use in potentially explosive atmospheres When the sampling device covered by this document is to be used in potentially explosive atmospheres, it shall comply with EN 50015 to EN 50017, EN 50020, EN 60079-0,
34、 EN 60079-1, EN 60079-7, EN 60079-18 and EN 60079-25. 5.3 Mechanical construction Every sampling device shall be constructed in such a manner that it is easily accessible for regular function checks and that airflow can easily be measured and calibrated. The sampling pump shall maintain the required
35、 airflow rate throughout the sampling period. NOTE Material used in the sampling head should be chosen to avoid moisture uptake and electrostatic charges. 5.4 Indicator devices An indicator device shall be provided to show that the sampling device is switched on. If the sampling device has more than
36、 one measuring range, the selected range shall be clearly identified. NOTE It is an advantage if elapsed time indicators, low flow rate indicators, flow interrupted indicators are given. 5.5 Adjustments Any equipment (switch, knob, etc.) used for modifying the operating parameters (sampling time, fl
37、ow rate, etc) of the sampling device shall be protected against involuntary action during sampling. The operational settings should be displayed. 5.6 Battery powered sampling devices Sampling devices powered with integral batteries shall be provided with an early indication of low battery condition.
38、 Short recharge time, light-weight and low noise levels are recommended. 5.7 Airflow-control During the sampling deviation from the required airflow should not exceed 5 %. 5.8 Airflow-meter A device to measure the airflow through the sampling device before and after sampling in the field should be s
39、upplied if required. NOTE This device can be different from that used for calibration. EN 14583:2004 (E) 8 Sampling devices with integral airflow meters shall be calibrated against a traceable external airflow meter before use. 5.9 Labelling and marking The source and the manufacturer of the samplin
40、g device shall be clearly identified to ensure traceability to published performance characteristics. 5.10 Instruction manual The instruction manual shall be written in a language, which is understandable in the country of the operator. It shall be easily understood and every function explained. It
41、shall illustrate all operation knobs and their handling by figures. It shall give the environmental and other conditions under which the instrument shall be operated including limitations to its use. It shall give exact calibration instructions and recommended equipment (e.g. flow meters) to be used
42、. The manual shall also give the address for service of the instrument. 5.11 Fraction to be sampled To measure personal exposure to bioaerosols the sampling device should follow the criteria for size fractions of airborne particles according to EN 481. 5.12 Physical sampling efficiency Physical samp
43、ling efficiency is defined in EN 13098 and EN 13205. It shall be measured as a function of particle aerodynamic diameter and other influent parameters. NOTE 1 Annex A gives some information about the physical behaviour of a sampling device and the experimental assessment of its physical sampling eff
44、iciency in the laboratory. Physical sampling efficiency can be interpreted as the percentage of ambient particles of specific size that are sampled and collected by the sampling device. As airborne micro-organisms often adhere to non-biological particles of various sizes, the measurement of micro-or
45、ganism concentration implies an accurate knowledge of this parameter. Sampling devices shall collect a representative sample of the required health related fraction of the bioaerosol (see EN 481). When assessing the performance of any bioaerosol sampling device, the overall sampling efficiency shall
46、 be determined. The performance of a personal sampler will be affected by the proximity of the operators body when worn within the breathing zone, and therefore personal inhalable sampling devices need to be assessed whilst attached to a torso or other well characterised equivalents. NOTE 2 Personal
47、 sampling is performed when assessing the exposure to evaluate a suspected disease. Many biological tests are more effectively carried out with a personal sampler used as a free standing device. A free-standing sampler can be used to scan the environment for high emissions of micro-organisms. 5.13 P
48、reservation efficiency Preservation efficiency is defined in EN 13098 as the capacity of the sampling device to maintain the culturability of the airborne micro-organisms during collection and also to keep the microbial products intact. The loss of culturability of micro-organisms due to sampling stress shall be tested on relevant model organisms. EN 14583:2004 (E) 9 5.14 Concentration range The manufacturer shall give the operational range and its limitations. An ideal sampling device should be able to sample conce
