ISO 9001 Calibration Requirements, Finally Explained in Layman's Terms

ISO 9001 Calibration Requirements, Finally Explained in Layman’s Terms

July 28, 2020

Calibrating your scales is crucial to getting an accurate result. Mismeasurement in either direction will affect your business, whether that means you lose out on payments or have unhappy customers who realized they were shorted. Calibrating scales is a routine aspect of any business that sells things by weight, and most (if not all) states have a standard for calibration that must be met.
ISO 9001 requires “measurement traceability” for any business that uses a measurement device. If you’re not selling goods that need to be measured, or nowhere in the entire manufacturing process are you measuring something that will affect the end results quality or specifications, you won’t need to adhere to this requirement—but if you are, it will behoove you to understand what’s required of you. Read on to learn about ISO 9001 and weight scale benefits in El Paso, TX.

ISO 9001 requirements

The goal of ISO 9001 is to hammer home the point that your scales need to be calibrated. It requires that you identify any devices that need to be calibrated, that you handle them properly so as not to affect their calibration status and that you have proof that they were calibrated.
ISO 9001 does not, however, tell you how frequently you must calibrate your devices. Depending on the type of measurements you need, the value of the product, whether they’re near devices or machinery that can vibrate and throw off the accuracy, or it is a critical measurement point that can affect your final product, you should probably calibrate your scales quarterly if not at least twice per year.
Working with an external calibration company can help you meet all three of these requirements. Companies like IWCS Scale will come to your business, show you how to handle scales properly and give you written documentation of your compliance.

Avoid these common mistakes

Here are some common mistakes to avoid regarding scale calibration:

  • Not identifying calibrated devices: When was the last time your scale was calibrated? If you have to dig for that information, you’re probably not as on top of your calibration requirements as you should be. Calibration stickers that detail the time and date your scale was last inspected and calibrated can help you keep that information handy.
  • Mishandling out of tolerance scales: If one of your scales is out of tolerance, you need to remedy it as soon as possible. Typically, an external company will not only notify you that there’s a problem with a specific device, but they will also provide a quote for how much it will cost to fix it. Remember to ask what the out-of-tolerance range was so you can determine if you need to go back and re-measure products or make adjustments.
  • Not handling scales properly: Scales can become uncalibrated if they’re not handled carefully. For example, dropping a smaller scale on the ground will certainly affect its accuracy. This can be avoided by asking your employees to let you know if anything happens to a scale, then recalibrating it as soon as possible.
