Analytical & Precision Balance Company has been doing on site calibrations of our customer's weighing instruments for over 40 years. For the past 18 years, we have been ISO 17025:2017 accredited through International Accreditation Service. We understand the critical nature of our client's samples. Our Scope of Accreditation with IAS allows us to calibrate instruments from ultra micro balances all the way up to 10,000 lb platform scales. We contact customers when their equipment is due for calibration. On the Certificate of Calibration, we let our customer know if the instrument was within tolerance before service. We also take four different readings on each certificate prior to service and after service. Measurements for linearity, reproduceability and eccentricity are also included on the Certificate. The calibration records are stored electronically and in hard copy for a minimum of 7 years. They are available to our customers via email.
In addition to our ISO 17025 accredited Certificate of Calibration, we also offer Combined Uncertainty Reports that are accredited with IAS. The Combined Type A and B Uncertainty Report can be done at the client�s request for an additional fee. The Combined Type A and B Uncertainty Report must be generated immediately after calibration of the instrument. Analytical & Precision Balance has developed a format and procedure for the estimation of uncertainty of all calibrations that it does. While estimating uncertainty of calibrations, all factors which effect the calibration are considered and reasonably estimated. The Combined Type A and Type B Uncertainty Report includes the estimated standard deviation on repeatability measurements, hysteresis, and worst-case eccentricity. The methods used for determining Combined Uncertainties are either the Root Sum Square Statistical Method, Total Collected Added Uncertainty or an Expanded Uncertainty with a Coverage Factor of k=2. Provided level of confidence: 95%. All measurements are performed with a minimum 4:1 test uncertainty ratio unless otherwise noted in comments section. Measurements reported are traceable to SI units via standards traceable to NIST. For more information, click here.
We understand that the majority of our clients are under various regulatory agencies such as the FDA, ISO, etc. As part of our support to our customers, we are available to walk the auditors through and answer any questions with regards to the calibration procedure and information included on our certificates of calibration.
Our Class 1 weights and calibration procedures are National Institute of Standards and Technology (N.I.S.T.) traceable. Additionally, our company is an ANS/ISO/IEC Standard 17025:2017 Accredited calibration laboratory. Our ISO Registrar is the International Accreditation Service (IAS).
