CoC number on side of legal for trade farmers market scale

First, in order for the scale to be legal for trade it needs to be NTEP approved. When a scale is NTEP approved it will have a certificate of conformance that is issued from NTEP. It is important to note that you won't receive that certificate when you purchase the scale. But, you will see the certificate number somewhere on the scale that you purchase. In this example above, the certificate number is 06-046. So you can easily go the the NTEP database and confirm if this scale is truly NTEP approved legal for trade.

You'll also notice a logo that shows "III". In the label above it is in the top left corner. This is refering to the approval which is for class 3. Weighing devices are separated into five accuracy classes according to number of scale divisions (n) and the value of the scale division (d). They are designated I, II, III, IIIL and IIII. Of greatest concern to us are class III and IIIL which are described as follows in Table 7 (a) of Handbook 44: III: All commercial weighing not otherwise specified, grain test scales, retail precious metals and semi-precious gem weighing, animal scales, postal scales and scales used to determine laundry charges.

In the same location the capacity and readability should be mentioned. The capacity is the maximum weight that the scale will handle before it overloads. The readability is the graduations the scale increments up or down in starting at 0.00 and going all the way to the capacity. In this example above, the max capacity is 40 pounds and the readability is 0.01 pounds. That means the scale should start at 0.00 and then go up in 0.01 pound increments until it reaches 40 pounds.

There are a few other items you will also notice. The manufacturer of the product is mentioned and the model number of the scale is listed. Also, the serial number of that particular scale is provided.
