The Laboratory Association of New Hampshire is a powerful networking tool for laboratories and industry professionals throughout New England. We offer the opportunity for like-minded individuals to interact and discuss issues that are important to all of us in the environmental field. The Association also works closely with select vendors to help members save on rising costs such as consumables and PT samples.

Please take the time as Lab Professionals to be familiar with the 2016 TNI Standard. as well as the NH ENV-C Rules. Even just read a little each day. You will be doing yourself and your Laboratory an invaluable service. Those of you certified in Massachusetts should be familiar with 310CMR and QSM Version 6.0 for The Department of Defense and Energy.
September 2025 TNI Tip of the Month!
5.5.13.1 Support Equipment
This Standard applies to all devices that may not be the actual test instrument, but are necessary to support laboratory operations. These include, but are not limited to: balances, ovens, refrigerators, freezers, incubators, water baths, temperature measuring devices (including thermometers and thermistors), thermal/pressure sample preparation devices, and mechanical volumetric dispensing devices (such as Eppendorf® or automatic dilutor/dispensing devices).
a) The results of any calibration or verification shall be within the specifications required of the application for which this equipment is used. The laboratory shall define the specifications for acceptability if none exist in method or regulation. If any equipment fails to meet the specifications for acceptability:
i. the equipment shall be removed from service until repaired; or
ii. the laboratory shall maintain records of established correction factors to correct all measurements.
b) The laboratory shall maintain all support equipment in proper working order. The records of all repair and maintenance activities, including service calls, shall be kept.
c) On each day the equipment is used, balances, ovens, refrigerators, freezers, incubators, and water baths shall be checked and documented. The acceptability for use or continued use shall be according to the needs of the analysis or application for which the equipment is being used.
d) Temperature measuring devices shall be calibrated or verified at least annually. Calibration or verification shall be performed using a recognized National Metrology Institute traceable reference, such as NIST, when available.
i. If the temperature measuring device is used over a range of 10°C or less, then a single point verification within the range of use is acceptable.
ii. If the temperature measuring device is used over a range of greater than 10°C, then the verification must bracket the range of use.
e) If quantitative results are dependent on their accuracy, such as in standard preparation or dispensing or dilution into a specified volume, the laboratory shall verify volumetric measuring devices as follows:
i. glass microliter syringes and Class A glassware are exempt from any verification requirements beyond what is stated in Section 4.6.2;
TNI Standard EL-V1M2-2016-Rev2.1: Quality Systems General Requirements

ii. disposable or single-use volumetric equipment shall be verified once per lot, prior to or in conjunction with its first use;
iii. mechanical devices shall be verified prior to first use and on a quarterly basis; mechanical devices used at more than one volume shall be verified at volumes bracketing the range of use, and at the mid-point of the volumes used by the device;
iv. all other volumetric support equipment shall be checked for accuracy prior to or in conjunction with its first use.
f) All other support equipment shall be calibrated or verified at least annually, using a recognized National Metrology Institute, such as NIST, traceable reference when available, bracketing the range of use.
g) Raw data records shall be retained to document equipment performance
