(i) Percent predicted FEV1 will be calculated according to prediction equations published in Spirometric Reference Values from a Sample of the General U.S. Population, American Journal of Respiratory and Critical Care Medicine, 159(1):179-187, January 1999 (incorporated by reference, see § 37.98).

(1) Testing personnel must fully comply with the 2005 ATS/ERS Standardisation of Spirometry guidelines for instrument calibration check procedures, pp. 322-323, including Table 3 (incorporated by reference, see § 37.98).

(i) For volume spirometers, calibration check procedures must include daily (day of testing) leak and volume accuracy checks. In addition, volume linearity checks must be performed according to the frequency established by the 2005 ATS/ERS guidelines.

(ii) For flow-type spirometers, calibration must be checked daily by injecting 3 liters of air from a calibration syringe at 3 different speeds (fast, medium, slow). Flow linearity must be checked weekly as established by the 2005 ATS/ERS guidelines.

(iii) Instrument calibration check records must be maintained by the facility and available for inspection by NIOSH, as deemed necessary.

(b) Spirometry testing equipment must meet the 2005 ATS/ERS Standardisation of Spirometry specifications for spirometer accuracy and precision and real-time display size and content, pp. 331-333, including Table 2 on p. 322 and Table 6 on p. 332 (incorporated by reference, see § 37.98). Facilities must make available for inspection written verification from a third-party testing laboratory (not the manufacturer or distributor) that the model of spirometer being used has successfully passed its validation checks as required by the Standardization of Spirometry; 1994 Update protocol, Appendix B pp. 1126-1134, including Table C1 (incorporated by reference, see § 37.98). Facilities may request such documentation from spirometer manufacturers. For each forced expiratory maneuver submitted for a miner under this part, the spirometry data file must retain a record of the parameters defined in the 2005 ATS/ERS Standardisation of Spirometry, p. 335 including Table 8 (incorporated by reference, see § 37.98). Spirometers that provide electronic transfer of spirometry data results files must use the format, content, and data structure specified by the 2005 ATS/ERS Standardisation of Spirometry, p. 335, or a procedure for data transfer that is approved by NIOSH.

(a) Interpretations will be carried out by physicians or other qualified health care professionals with expertise in spirometry who have all required licensure and privileges to provide this service in their State or Territory. Interpretations must be carried out using procedures and criteria consistent with recommendations in the ATS Technical Standards: Spirometry in the Occupational Setting, pp. 987-990, and the ATS/ERS Interpretative Strategies for Lung Function Tests, p. 950, p. 956 including Table 5, and p. 957 including Table 6 (both incorporated by reference, see § 37.98).
