1. A juicer is a machine that can quickly squeeze fruits and vegetables into fruit and vegetable juice. It is small and can be used at home. The juicer uses a motor to drive the knife net to rotate at a high speed. Push the fruits and vegetables from the feeding port to the knife net, the sharp thorns of the knife net will chop the fruits and vegetables, under the action of the centrifugal force of the juicer generated by the high-speed operation of the knife net, the pulp will fly out of the knife net into the slag box, and the juice will pass through. The knife net flows into the juice cup.

2. UL certification is a safety certification. As an effective means to eliminate technical barriers to international trade, UL also plays an active role in promoting the development of international trade. Juicers exported to the United States need to apply for UL certification, and products with the UL certification mark can bring consumer confidence.

Juicer UL certification standard: UL982, the standard is for household mixers and kitchen accessories that are used for short periods of time and result in less than 100 hours of use per year.

3. The main tests for UL certification of juice extractors include:

Operation test, starting current test, leakage current humidity test, input test, normal temperature test, dielectric withstand voltage test (/lsec), interlock system durability, switch overload test, water immersion (inlet) test, water immersion (overflow) test , abnormal test, locked rotor test, severe use condition, normal condition test (100C&7h, motor), running burnout test, strain relief test, mold stress relief deformation test, mold stress relief test, after mold stress input, impact test, stability test , packaging test, etc.

4. Process for UL certification of juicer:

1. Project application – submit a certification application to the supervision of the testing agency.

2. Data preparation – According to the requirements of UL certification, the enterprise prepares relevant certification documents.

3. Product testing – the company sends the samples to be tested to the laboratory for testing.

4. Preparation of reports – certified engineers prepare reports based on qualified test data.

5. Submit for review – the engineer will review the complete report.

6. Issuing a certificate – After the report is reviewed and verified, a certificate will be issued.
