d. Criteria for the acceptance of an instrument calibration must be established, such as correlation coefficient or relative standard deviation. The criteria used must be appropriate to the calibration technique employed and must be documented in the laboratory's SOP.

e. If allowed in the permit, program or rule, results of samples outside of the concentration range established by the calibration must be reported with defined qualifiers, flags or explanations estimating the quantitative error.

f. The following must occur for methods employing standardization with a zero point and a single point calibration standard:

(i) Before the analysis of samples, the linear range of the instrument must be established by analyzing a series of standards, one of which must encompass the single point quantitation level;

(ii) A zero point and a single point calibration standard must be analyzed with each analytical batch;

(iii) A standard corresponding to the RL must be analyzed with each analytical batch and must meet established acceptance criteria;

(iv) The linearity must be verified at a frequency established by the method or the manufacturer; and

(v) If allowed in the permit, program or rule, a sample result within an analytical batch, higher than its associated single point standard, can be reported if the following conditions are met:

(1) A standard with a concentration at or above the analyte concentration in a sample must be analyzed and must meet established acceptance criteria for validating the linearity;

(2) The sample must be diluted such that the result falls below the single point calibration concentration; or

(3) The data must be reported with an appropriate data qualifier or an explanation in the narrative of the test report.

g. If the instrument calibration results are outside established acceptance criteria, corrective actions must be performed and all associated samples reanalyzed. If reanalysis of the samples is not possible, data associated with an unacceptable instrument calibration must be appropriately qualified on the test report.

h. Calibration standards must include concentrations at or below the limit specified in the permit, program or rule.

i. If an approved method does not specify the number of calibration standards, the minimum number is three, one of which must be at the RL, not including blanks or a zero standard, with the exception of instrument technology for which it has been established by methodologies and procedures that a zero and a single point standard are appropriate for calibrations. The laboratory must have an SOP that documents the protocol for determining the number of points required for the instrument calibration employed and the acceptance criteria for calibration.

j. It is prohibited to remove data points from within a calibration range while still retaining the extreme ends of the calibration range.

4. Calibration verification

a. When an instrument calibration is not performed on the day of analysis, the instrument calibration must be verified before analysis of samples by analyzing a calibration standard with each batch.

b. If calibration verification is not described in the approved method, calibration verification must be repeated at the beginning of each batch, after every tenth sample, excluding QC samples, and at the end of each batch.

c. Sufficient raw data records must be retained to permit reconstruction of the calibration verification, such as: test method; instrument; analysis date; each analyte name, concentration and response; calibration curve or response factor; or unique equations or coefficients used to convert instrument responses into concentrations. Calibration verification records must explicitly connect the verification data to the instrument calibration.

d. Criteria for the acceptance of calibration verifications must be established and evaluated using the same technique used to evaluate the instrument calibration.

e. If the calibration verification results obtained are outside established acceptance criteria, corrective actions must be performed. If routine corrective action procedures fail to produce a second consecutive (immediate) calibration verification within acceptance criteria, then the laboratory must either demonstrate performance after corrective action by performing one successful calibration verification or perform a new instrument calibration. If the laboratory has not demonstrated acceptable performance after the corrective action, sample analyses must not occur until a new instrument calibration is established and verified. Sample data associated with unacceptable calibration verification may be reported as qualified data under the following special conditions if allowed in the permit, program or rule:

(i) When the acceptance criteria for the calibration verification are exceeded high (high bias) and all associated samples contain analytes below the RL, those sample results may be reported.

(ii) When the acceptance criteria for the calibration verification are exceeded low (low bias), the sample results may be reported if the concentration exceeds a maximum regulatory limit as defined by the permit, program or rule.

f. When allowed by permit, program or rule, verification procedures may result in a set of correction factors. If correction factors are employed, the laboratory must have procedures to ensure that copies of all data records, such as in computer software, are correctly updated.

g. Test equipment, including both hardware and software, must be safeguarded from adjustments that would invalidate the test results.
