TR 07-02two-weekly zero/span checks by means of an accurate known concentrationundertaken on each gas analyser.b) These quarterly and two-weekly zero/span checks and any actions taken as aresult thereof must be clearly documented as part of the Quality documentation.These results will be used to assess the organisation’s ability to perform theirmonitoring activities within the scope of their accreditation.c) The requirements for analysers to be dynamically calibrated at site are asfollows:i. when analyser is initially installed;ii. every three months;iii. if any repair is done on the analyser;iv. if tolerances of zero/span checks are not met;v. if analyser is relocated.d) Monitoring stations that do not have an on-board multipoint calibration devicemust have their analyzers calibrated on site by an accredited laboratory.e) Monitoring stations that incorporate their own devices can undertake thequarterly calibrations. One of the four annual calibrations of the equipment shallbe calibrated by an accredited laboratory. They must participate in interlaboratorycomparisons every 18 months. Portable calibrators shall be checkedbefore and after use. Certified reference gases shall be used to check on the inhousecalibrations.4.6 Data Management Protocols4.6.1 It is important to ensure that air quality data is properly validated and managed after itis obtained.4.6.2 The facility shall maintain records in accordance with the methods used, the qualitysystem and the retention period as required by legislation.What data quality assurance processes are in place?What supplementary data needs to be collected?Other information may be relevant to the study (eg, meteorological conditions,process data and traffic flows).4.7 Accredited Dataa) A copy of the raw data shall always be available and shall be stored at oneminute intervals.b) A record and motivation must be kept of any corrections/alterations done to theraw data including zero/span.c) All multiplication factors/algorithms/manipulations on the data must be recordedand reported.d) Accurate and detailed operations on site, e.g. changes to analyser settings,must be reported in a site operations report.e) Data must be kept for a minimum of three years.4.7.1 There will be only one level of accreditation for ambient air pollution monitoringstations.a) If data is suspect it may not be used until investigation has shown it to be validin terms of the scope of accreditation.©SANAS Page 8 of 12
TR 07-02b) Stations can supply data for 80% (per parameter) of the monitoring period (notless than three months) within the accuracy of their accreditation.Note: Where data captured is less than 80% reasonable cause shall be documented.c) See Appendix A4.8 Data Acquisition (Logging Devices)a) Output from the analyser must be recorded.b) The accuracy of the logging device must be verified annually.c) Hourly mean concentrations must be generated.d) The logger must be able to scan at minimum 10 second intervals with a minimum scanperiod of 1 hour.e) The calculation of the mean requires data points to be collected for a minimum of 40minutes uninterrupted.f) The mean and standard deviation calculation requirements shall be verified againstsoftware4.9 Data ValidationRefer to SANS 1929:20094.10 Reporting of data & compliance to specificationsWhen data is reported the temperature and pressure at which the analyzer was last calibratedmust be indicated on the test report. Any statement of compliance to specifications shall bebased on ILAC G8:2009.• How will data be stored and reported?• What time format should be used?• How will exceedences be determined and reported?4.11 Staff CompetenceThe facility shall have access to people that have competencies in, or shall have staff thathave amongst other competencies, competence in:• air quality legislation;• air quality monitoring;• equipment operation and maintenance provided by equipment manufacturers;• conducting of in-house calibrations where applicable;• ISO/IEC 17025:2005;• internal auditing of the quality system and technical activities of the facility.4.12 Internal AuditsThe facility shall ensure that all aspects of their quality system including their testing activitiesand where applicable their calibration activities are subject to an internal audit to confirmcompliance to ISO/IEC 17025:2005 requirements, SANAS requirements and any relevantlegislation. All monitoring stations shall be audited against SANAS TR07 requirements“Supplementary Requirements for the Accreditation of Continuous Ambient Air PollutionMonitoring Stations” within a 12 month planned audit timeframe. Corrective actions taken at aspecific station shall be investigated for its applicability to other stations.©SANAS Page 9 of 12
