No matter what type of assembly is being manufactured, accurate torque measurement is essential to a quality product. ASG recommends that all torque products be calibrated on a regular basis to maintain quality operation and avoid unnecessary disruptions to your business.
ASG offers calibration services, performed and traceable to NIST standards, and issues a paper Calibration Certificate.
Calibration does two main things: ensures the proper tolerances are being met by each individual machine, and ensures consistent alignment to specific standards across all manufacturers for any given machine. So not only will a properly calibrated machine perform its task to the precision specified, but any machine that conforms to the same calibration standards will perform the same, within the tolerances of the standard.
NIST, or The National Institute of Standards and Technology, is an agency of the United States Department of Commerce. Its mission is to promote American innovation and industrial competitiveness. NIST essentially sets the standards for measurement which guide us in our calibration efforts.
All calibration certificates follow a certain structure. The document has various information about the device, along with the original standards. Here’s a basic structure of a calibration certificate:
- Title: The certificate name
- The details of the service center/laboratory tasked with the calibration
- Customer details
- A unique identification code for the calibration certificate
- The device name and details
- Details on the environmental conditions where the calibration took place
- Calibration results with respective sign conventions
- Name, designation, identification, and signature of the person in charge of the calibration
- A statement that specifies these test results are only relevant to this specific device
- Evidence that the measurements are traceable
Some of these details may not be present or can change depending on the device that you purchase.
The ASG Service Department can calibrate most any tool and we have live technicians standing by during business hours to help you with your questions.
We even calibrate our own calibration equipment, as seen below with the DTT Torque Tester:
NIST Fun Facts
- NIST became NIST in 1988 after an 87-year run as the National Bureau of Standards.
- NIST conducted the official investigation into the collapse of the World Trade Center buildings.
- NIST’s laboratory in Boulder, CO has an atomic clock which
serves as the nation’s official time.
- As you would expect from an agency which sets and maintains standards, it has an accuracy to about one second in 20 million years, and this amazing clock looks mesmerizing in action:
