An electronic scale is a tool that uses Hooke's law or the lever balance principle of force to determine the mass of an object. It is mainly composed of three parts: load-bearing system (such as weighing pan and weighing body), force transmission system (such as lever force transmission system and sensor) and value indication system (such as dial and electronic display instrument).
The load-bearing mechanism and force transmission system of the electronic scale transmit the weight or force of the weighed object to the load cell, and the load cell converts the non-electric quantity (mass) into the conversion element of the electric quantity, and converts it into a physical quantity (usually the amount of electricity, such as voltage, current or frequency, etc.) that is convenient for measurement according to a certain functional relationship (usually a linear relationship). The general display instrument handles the electronic circuits (including amplifiers, AD converters, etc.) and indicating components (such as display, printing, etc.) of the load cell signal. The power supply is a highly stable excitation power supply that feeds power to the load cell measurement bridge, which can be an AC or DC regulated power supply.
The UL466 standard is a safety standard for electronic scale products, which was developed by the Underwriters Laboratory (UL) in the United States. This standard mainly covers the safety requirements of electronic scales in terms of electrical, mechanical, and performance to ensure that electronic scales will not cause harm to users during use.
The UL466 standard has detailed regulations and test requirements for the electrical safety, mechanical properties, environmental adaptability and other aspects of electronic scales to ensure that electronic scales can work safely, accurately and reliably during use.
UL466 is a U.S. safety standard for electronic scales, and if your electronic scale is going to be exported to Amazon US, you need to provide a report that meets the UL466 standard.
To get a UL466 report, you need to follow these steps:
Contact UL Certification Body: UL is the abbreviation of Underwriters Laboratories, which is the authoritative loss prevention safety testing and certification body in the United States. You will need to contact the UL certification body to provide them with the technical specifications and design drawings of the scale.
Submit application and sample: If you are sure that you can pass UL466 certification, you need to submit an application and sample to UL. The application needs to include the technical specifications, design drawings, instructions for use and other documents of the electronic scale, and the samples need to be prepared in accordance with the requirements of UL.
Lab Testing: UL Certification Bodies will perform lab tests on your scale to determine if it meets UL466 standards. The test content may include electrical safety test, mechanical performance test, environmental adaptability test, etc.
Reporting and certification: If your scale has passed a lab test, a UL certification body will issue a UL466 report certifying that your scale complies with the UL466 standard. You will need to submit the report to Amazon US to demonstrate that your product meets local regulatory requirements.
It is important to note that the UL466 standard may be constantly updated and changed, so you need to keep an eye on the latest requirements of the standard so that you can adjust your scale design and production in a timely manner.
