# LIST OF DESIGNATED REFERENCE AND EQUIVALENT METHODS

Issue Date : June 6, 2012 (www.epa.gov/ttn/amtic/criteria.html)

These methods for measuring ambient concentrations of specified ai r pollutants have been designated as "reference methods" or "equivalent methods" in accordance with Ti tle 40, Part 53 of the Code of Federal Regulations (40 CFR Part 53). Subject to any limitations (e.g., operati ng range or temperature range) specified in the applicable designation, each method is acceptable for use in state or local air quality surveillance systems under 40 CFR Part 58 unless the applicable designation is subsequently canceled. Automat ed methods for pollutants other than PM 10 

### are acceptable for use only at shelter temperatures between 20°C and 30° C and line voltages between 105 and 125 volts unless wider limits are specified in the method description. Prospective users of the methods listed should note (1) that each method must be used in strict accordance with its associated operation or instruction manual and with applicab le quality assurance procedures, and (2) that modification of a method by its vendor or user may cause the pertinent designation to be inapplicable to the method as modified. (See Section 2.8 of Appendix C, 40 CFR Part 58 f or approval of modifications to any of these methods by users.) Further information concerning particular designations may b e found in the Federal Register notice cited for each method or by writing to the National Exposure Research Lab oratory, Human Exposure and Atmospheric Sciences Division (MD-D205-03), U.S. Environmental Protection Ag ency, Research Triangle Park, North Carolina 27711. Technical information concerning the methods should be obtained by contacting the source listed for each method. Source addresses are listed at the end of the listing of method s, except for the addresses for lead method sources, which are given with the method. New analyzers or PM 10 

### samplers sold as reference or equivalent methods must carry a l abel or sticker identifying them as designated methods. For analyzer s or PM 10 

### or samplers sold prior to the designation of a method with the same or similar model number, the model numb er does not necessarily identify an analyzer or sampler as a designated method. Consult the manufacturer or seller to d etermine if a previously sold analyzer or sampler can be considered a designated method or if it can be upgraded to design ation status. Analyzer users who experience operational or other difficulties with a designated analyzer or s ampler and are unable to resolve the problem directly with the instrument manufacturer may contact EPA (preferably i n writing) at the above address for assistance. This list will be revised as necessary to reflect any new design ations or any cancellation of a designation currently in effect. The most current revision of the list wi ll be available for inspection at EPA's Regional Offices, and copies may be obtained at the Internet site identified above or b y writing to the National Exposure Research Laboratory at the address specified above.

### Notes

1 Users should be aware that designation of this ana lyzer for operation on ranges less than the range s pecified in the performance specifications for this analyzer (40 CF R 53, Subpart B) is based on meeting the same absol ute performance specifications required for the specified range. Th us, designation of these lower ranges does not impl y commensurably better performance than that obtained on the specified ran ge.

2 This analyzer is approved for use, with proper fac tory configuration (if applicable), on either 50 or 60 Hertz line frequency and nominal power line voltages of 115 VAC and 230 VAC, or similar voltages as specified in the operat ion or instruction
manual associated with the method.
