If you do any research on the internet about scale companies and ISO, then most of the time you will only read about how great the certification is and how that is the only way to go. Well, we are going to provide you with a different point of view on the question, should you choose an ISO certified scale company?

The International Organization for Standardization is an international independent, non-governmental organization with a membership of 168 national standards bodies. Their history can be traced back to 1946. The organization develops and publishes international standards. The purpose of achieving ISO certification is to ensure the safety and quality of the product or service. 

There is certainly an argument to be made for the benefit of a scale manufacturer (or any manufacturer) to have quality guidelines and to be ISO compliant. In this situation, it likely makes really good sense. In fact, most of our top scale manufacturers that we offer are ISO 9001. It is a good thing for companies with a lot of employees or companies that build things to a consistent quality level. It’s essentially all about documenting your process and training your staff to follow that process so you produce a consistent product.

However, for a small scale service company with less than ten employees…. does it really make sense to spend thousands of dollars just to have an independent group “approve” or “accredit” how you’ve been successfully operating your business for over forty years?  

BENEFITS FOR A SCALE COMPANY TO BE ISO CERTIFIED

The ISO certification for scale companies is referred to as ISO/IEC 17025. In order to earn ISO 17025 certification, an industrial scale company must survive an accreditation process from a certified third-party organization that is often expensive and time consuming. And, that’s just the approval, the scale company will also be evaluated every few years in order to renew their certification.

If a scale company has earned ISO 17025 certification they can then boast about their ability to provide high quality precise testing and calibration results and how they can follow a quality management system. 

Some of the external organizations that provide this certification to scale companies are the American Association for Laboratory Accreditation (A2LA) and the Perry Johnson Laboratory Accreditation (PJLA). The process of becoming ISO certified takes time and costs money and of course there is a renewal process that we mentioned earlier which also costs money.  

BUT I HAVE TO USE A CERTAIN TYPE OF SCALE COMPANY….

One area that is often misunderstood is what customers require or don’t require. Often a customer will be under the impression they can only use a ISO 17025 certified scale company, as specified by their internal quality manual. 

The fact is that scale companies are not required to have ISO 17025 accreditation. There are some folks who will argue that the ISO accreditation provides extra credibility to the scale company and that having an ISO 17025 certificate of calibration displays superior quality control, as opposed to getting a non-ISO 17025 certified calibration of your scale.  You’re also likely to pay a higher hourly rate for this type of scale service as well, even though the scale company is using the same test weights as any other legitimate scale company.

NEGATIVES FOR A SCALE COMPANY TO BE ISO CERTIFIED

So you could almost compare three different categories: (1) ISO scale companies, (2) scale companies who achieved ISO and didn’t renew (but still employ some of the positives w/o the recurring fees) and (3) those that are truly non-ISO scale companies.

But for simplicity, let’s take a moment to truly compare an ISO certified scale company versus a non-ISO scale company.

The following are important points to remember. You can also argue that a scale company, whether ISO or not, is using: the same Class F weights. Those same test weights are tested at the state lab each year (traceability to NIST) for both scale companies. Both scale companies have licensed scale technicians. Both scale companies are documenting the results of the scale check online using Pass / Fail calibration software with tolerances, etc…. So, we have to ask the question…. What exactly are you paying extra $$$ for?

Let’s put this in table form just to make sure you see and understand this.

So, once again we have to ask the question…. What exactly are you paying higher hourly rates for?    Continue reading →
