Why Are Scales Not Legal for Trade

When choosing a specific scale for your application, you need to answer a key question. What is the minimum and maximum weight of the product that must be weighed by the scale? The minimum weight tells you about your maximum pitch size (accuracy/legibility) of the scale, while the maximum weight corresponds to the required capacity of the scale. As there is a wide range of legal scales for trade balances, we have again divided them into grade levels to make it easier for you to find the right type of scale for your specific application. Now that you know all about NTEP certification and its different school levels, it`s time to find out if legal scales for trade are the right device for your business. In general, legal trade scales are most often used in industrial environments and in any industry requiring a commercial sale or purchase by weight. Common industries for legal commercial scales are: The symbol you need to look for is the six-pointed star. This stamp or sticker must be affixed to the approved equipment that has been rejected. It is a criminal offence to use weighing machines with a six-pointed star for a lawful purpose. Measurement Canada is responsible for ensuring that consumers are offered fair and reasonable prices based on accurate measurements. The Department also receives complaints, conducts investigations and certifies trade balances. Not only does your legal trade scale need to be certified, but Canada`s Weights and Measures Act also requires that your scale be calibrated frequently to ensure accuracy. There are hefty fines for scales that are outside the permissible margin of error.

Of the 20,000 scales inspected in England in 2014-2015, 260 were found to be fake with 28 days` notice. In the case of outlets, approximately 200 of the 2200 outlets visited were found to be non-compliant. I hope we have answered your questions, what does NOT LEGAL FOR TRADE mean on a scale?

Directive 2014/31/EU on non-automatic operating scales (NAWI) lists four applications in which commercially approved scales must be used: But what are the reasons why a scale might be rejected by commercial standards for legal use? Marsden explains. Legal scales for trade are divided into classes based on their different levels of accuracy (i.e. mass standards) to ensure traceable and accurate measurement. The manufacturer of a scale assigns its accuracy class based on the design of the device and the intended application. Manual 44 contains specifications and tolerances for each accuracy class.

In order for a balance to be approved and licensed for a specific accuracy class, it must meet NIST specifications, tolerances, and requirements for its intended use. Here is a breakdown and overview of the four main accuracy classes: At Alliance Scale, we offer a wide range of NTEP certified scales that can help your business do business efficiently and legally with products sold by weight. Take a look at our product page to find your perfect fit. Remember, finding the right scaling style for your business needs is only half the battle. Being smart in maintenance is the other half. Incorporate regular, ongoing inspections into your operating cost forecasts and you`re much less likely to have a broken scale again on a busy day. Marsden has a range of commercially approved scales. This area includes: In Canada, trade approval is governed by tests and standards established by Industry Canada as part of Measurement Canada`s approval process. This approval is mandatory whether the item is certified by the NTEP or not. Table 7a of Manual 44 provides a breakdown of the description of each class. Class III states: “All commercial weighings not otherwise specified, grain test scales, retail weighers of precious metals and semi-precious stones, animal scales, postal scales, vehicle scales with a capacity of 30,000 pounds or less and scales used to determine laundry charges.” If you sell products commercially because of their weight, the law requires that the scales used be “legal for trade”. Legal scales for trade balances will have NTEP compliance certification.

If a scale has this certification, it means that the scale can meet the requirements of NIST 44. Once a legal commercial scale has been acquired, it must be reported to the county concerned. The county will then seal it and the scale can be used legally. Knowing what is not legal for trading is useful in a trading environment. Scales that are legal for trade are often those intended for the manufacturer to be used for commercial purposes when an item is sold by weight. The definition of commercial applications may vary slightly across jurisdictions and different weights. Various station tests and stress tests are carried out with an increasing and decreasing load. These scales are tested at different temperatures (50°F to 86°F) for approval by the NTEP.

A half-capacity load is applied to scales at least 100,000 times. * Regardless of capacity, a legal trading scale must have 5000 departments. For example, a 5000 lb capacity scale would count with 5000 divisions in the 1 lb graduations. Here are some examples of applications where NTEP-approved scales can be used: If you want to buy a legal scale for trading, there are three things to consider. As a scale company, we generally recommend choosing a legal brand name for trade scales whenever possible. This allows us to be sure to put the Central Carolina Scale name behind the devices that have been tested and approved. Determining whether your business needs a legal scale for trade is pretty straightforward. If you are in a business or industry where you sell your goods by weight, a regular scale will not be enough, you need a legal trade scale. The first step in buying a scale is to determine the type of scale you need. Without a doubt, this is the first step, regardless of the type of scale you buy. The deciding factor in choosing your scale that is best for you is whether or not you use the scale now or in the future to buy or sell products based on weight. In total, there are three types of scales: legal scales for trade, not for trade and not for trade balances.

The Canadian Weights and Measures Act requires by law that any company selling products by weight use a legal trade scale approved and certified by an authorized service provider. Before being considered legal for trading, it must be reviewed in accordance with section 8(b) of the Weights and Measures Act. (If your Legal For Trade balance requires an initial inspection, click HERE to book your service). NTEP stands for National Type Evaluation Program. The National Type Assessment Program is managed in collaboration with the National Conference on Weights and Measures (NCWN) and the Weights and Measures Division of the National Institute for Standards and Technology (NIST). According to the NTEP, the term “legal for trade” refers to any equipment used to sell, buy, process, exchange or determine the cost of products whose basis for measurement is weight. The NTEP program is an established process that rigorously tests and evaluates device compliance to meet all government standards and requirements. Government standards are set by NIST and are described in its NIST Handbook 44. The NIST standards in Manual 44 cover all aspects of an NTEP scale, including capacity, accuracy, the effects of environmental factors such as temperature and humidity, and even how a manufacturer`s name may appear on the scale. Each NTEP scale indicates an NTEP certificate or compliance number. This allows local inspectors to obtain a copy of the certificate of conformity and confirm that the make and model of your scale have been manufactured in accordance with NIST standards. It is also important to understand that local communities may apply rules and regulations that may deviate from NIST and NTEP standards.

For this reason, you should always check with your local weights and measures department to ensure that your scales comply with the specific regulations in your area. By the way, if you`re curious about whether your current scale is legal for trading, just look at the scale somewhere and you should see a CoC# on the sticker or plate. You can also view the scale on the ncwm website. Measuring and weighting agents around the world are responsible for managing legal matters relating to commercial equipment, as well as all related laws.
