Attachment A Specifications Specifications for Recalibration Services for the specific equipment listed in RFB 582-25-

08600 For use by the Texas Commission on Environmental Quality (TCEQ)

12100 Park 35 Circle, Bldg. B, Austin, TX 78753

Minimum General Specifications

1. Every year calibration services are to be performed on any one ML-500 base and associated 500 cells and up to any two ML-800 bases and their corresponding three cells.

2. TCEQ is requesting an option to renew this service for one (1) one-year periods from April 01, 2025, through August 31, 2025, renewing September 1, 2025, through August 31, 2026.

3. The below table is a current list of TCEQ’s MesaLabs BIOS inventory. This listed equipment is subject to change as new equipment is purchased.

4. Product maintenance, pre and post dynamic flow comparisons and full dimensional calibration shall be undertaken against full manufacturer’s specifications:

a. For the ML-500 Base Unit and the ML-800 Base Unit, flows from the flow cells must be clearly displayed without intermittent shorting of the display

b. For the ML-500 High Flow Cells (ML-500-44), flows must be between 500 and 50000 standard cubic centimeters per minute with a volumetric uncertainty of +/-0.25% (standardized accuracy of +/-0.40%) where the measurement uncertainty is stated as a percent of reading (including standardization, if applicable) with a 95% confidence interval. (k=2)

c. For the ML-800 Ultra Low Flow Cells (ML-800-3), flows must be between

0.5 and 50 standard cubic centimeters per minute with a standardized / volumetric uncertainty of +/-0.25% plus 0.002 standard cubic centimeters per minute where the measurement uncertainty is stated as a percent of reading (including standardization, if applicable) with a 95% confidence interval. (k=2)

d. For the ML-800 Low flow Cells (ML-800-10), flows must be between 5 and 500 standard cubic centimeters per minute with a standardized / volumetric uncertainty of +/-0.15% standard cubic centimeters per minute where the measurement uncertainty is stated as a percent of reading (including standardization, if applicable) with a 95% confidence interval.

(k=2)

e. For the ML-800 High Flow Cells (ML-800-44), flows must be between 500 and 50000 standard cubic centimeters per minute with a standardized / volumetric uncertainty of +/-0.15% standard cubic centimeters per minute where the measurement uncertainty is stated as a percent of reading (including standardization, if applicable) with a 95% confidence interval.

(k=2)

5. Where equipment is found to be out of specification, full performance test results, in the as-received condition, must be obtained before any adjustment or repair action is taken.

6. On completion of the calibration work, a certificate of calibration is required, signed by the authorized representative, containing a statement confirming that the calibration can be demonstrated to be traceable to National or International standards on a recalibration interval of 24 months

7. On completion of the calibration work, a certificate of calibration is required, signed by the authorized representative, containing a statement confirming that the calibration is in full compliance with its performance specifications.

8. Any omission from the full calibration are to be notified to TCEQ and shall be agreed in writing before a certificate, clearly annotated “Partial Calibration” is issued.

9. Must have a response time of 80 seconds or less per volumetric reading.

10. Must have a standardized accuracy of no greater than +/- 0.40%.

11. Must have a volumetric accuracy of no greater than +/- 0.25%.

SPECIAL TERMS AND CONDITIONS

A. Delivery to be made to TCEQ, 12100 Park 35 Circle, Building B, Austin, Texas

78753. Routine delivery response to the agency shall be within 60 calendar days after receipt of order.

B. Warranty period: complete coverage of system, parts and labor for a minimum of one year from date of acceptance following the testing period as described in C below.

C. The goods or materials ordered with this request will be tested upon receipt.
