Do you use a scale to sell products by weight? Then you are legally required to use a verified (legal-for-trade) scale. In this blog you will read how to recognise such a scale, what to look out for and how to get your scale verified.
Why is a verified scale mandatory?
When you sell on the basis of weight, you must be able to show that your weighing instrument measures correctly and reliably. An approved scale prevents disputes with customers, provides transparency and ensures that you comply with the applicable laws and regulations. During an inspection you must be able to show that your scale is suitable for trade use.
How do you recognise an approved scale?
A scale that you may use to charge for goods must carry two mandatory markings:
1. CE marking
The CE marking indicates that the device complies with the European directives on safety, health and the environment. This marking is usually visible on a sticker or type plate on the scale.
2. M mark with year
The M mark shows that the scale has been approved for trade use. The letter M is followed by a year, for example M23 for verification in 2023. This indicates when the verification was carried out.
Please note: scales verified before 2016 may carry a green sticker with an M in a square. These remain valid as long as the scale functions correctly.
Where can you find the CE and M markings?
The markings can usually be found on a sticker on the side, back or underside of the scale. Sometimes they are also located near the display or close to the serial number. It is advisable to check them regularly.
What does the M mark mean?
The M stands for "metrology". The number next to the M indicates the year of approval, so you can check how recently the verification was carried out.
Is a verified scale mandatory for trade use?
Yes. As soon as you sell goods on the basis of weight, you are required to use an approved scale. If you use a non-approved scale, you risk a fine and possible legal consequences. It can also damage your customers' trust.
How long does a verification remain valid?
An initial verification remains valid as long as the scale continues to function correctly. However, you must be able to show that the measurement is still correct. Regular checks or re-verification are therefore advisable.
How often should you have a scale checked?
Although the initial verification does not have to be repeated every year, we strongly recommend having your scale checked at least once a year. This prevents measurement deviations, helps you meet the legal requirements and keeps you prepared for unexpected inspections.
Preferably have this done by a specialist service company. They have the right equipment and knowledge to check and calibrate your scale properly.
