  The following types of products typically require an EMC testing 1. Home appliances: such as TVS, refrigerators, washing machines, air conditioners, microwave ovens, rice cookers, etc. These products may produce electromagnetic radiation or electromagnetic interference by other electrical appliances in daily use. 2. Information technology equipment: including personal computers, servers, routers, switches, printers, scanners, mobile phones, tablet computers, notebook computers, etc., these devices are sensitive to the electromagnetic environment and may produce electromagnetic interference. 3. Industrial control and automation equipment: PLC (programmable logic controller), DCS (decentralized control system), frequency converter, motor driver, industrial robots, etc., these equipment operate in the industrial environment, the requirements for electromagnetic compatibility are very high. 4. Medical equipment: electrocardiogram machine, monitor, ultrasonic diagnostic instrument, he...

  Salt spray test is carried out in the salt spray test box, is generally used to test the corrosion resistance of metal or corrosion resistance of metal surface electroplating, can be through corrosive salt solution spray to corrosion test, but also can be conducted by corrosive gas test, according to the specific use environment to adopt different ways of corrosion. When doing the salt spray test, there is basically a set of test standards and test rating judgment. The corrosion condition of salt spray test is mainly determined by four methods, rating method, weighing method, corrosion appearance determination method and corrosion data statistical analysis method. Corrosion data statistical analysis method provides the method of designing corrosion test, analysis of corrosion data and determination of the confidence of corrosion data. It is mainly used for the analysis and statistics of corrosion, rather than specifically for the quality determination of a specific product.

  The EMC (Electromagnetic Compatibility) test is a capability test to assess whether a device or system can function properly in an electromagnetic environment without producing unbearable electromagnetic interference (EMI) from anything in its surrounding environment. Almost all electronic devices or systems, before marketing or use in certain occasions, require EMC testing to ensure that they meet the relevant national or international standards, thus protecting the equipment itself, users, and other surrounding equipment from electromagnetic interference. The main reasons for requiring EMC (Electromagnetic Compatibility) testing are as follows: Ensure the electromagnetic compatibility of the product Avoid electromagnetic interference : EMC testing can assess the behavior of the product in the electromagnetic environment to ensure that it does not produce unacceptable electromagnetic interference (EMI) to other equipment or systems. This interference may lead to performance degr...

  Intelligent switch is   the unit that uses the combination and programming of the control board and electronic components to realize the intelligent switch control of the circuit. Switch control, also known as BANG-BANG control, because this control mode is simple and easy to implement, so it is adopted in the control of many household appliances and lighting lamps. But the conventional switch control is difficult to meet the requirements of further improving the control accuracy and energy saving. According to the relevant part of the Federal Communications Regulations of the United States (Part CFR 47), all electronic products entering the United States (mainly for the working frequency of 9 KHz-3000GHz electronic products) need to conduct electromagnetic compatibility certification (FCC certification), so FCC certification is mandatory in the United States.

  Electric thermostaticdrying oven is a commonly used laboratory and industrial equipment, mainly used for drying, heating and baking of various samples and materials. It ’ s working principle is to use the heat provided by the electric heating element to circulate the hot air through the blower , so that the material is dried at constant temperature. Specifically, the electric heating element is energized and raises the air temperature; the blower forces the hot air through the box, and the hot air contacts the moisture in the sample; the water vapor is discharged through the exhaust port to achieve the purpose of drying the sample. Electric thermostaticdrying oven   is a powerful and versatile laboratory and industrial equipment. Its working principle is easy to understand and relatively easy to operate and maintain. In the process of use, we need to pay attention to the safety operation specifications, and choose the appropriate models and specifications according to the ac...

  CE certification of intelligent voice lamp mainly involves EMC electromagnetic compatibility instruction 2014 / 30 / EU and LVD low voltage instruction 2014 / 35 / EU. The main detection criteria: EN60598-1, EN60598-2-X, EN55015, EN61547, EN 61000-3-2, EN 61000-3-3. Electromagnetic Compatibility (EMC) directive 2014 / 30 / EU Introduction: When close to each other, all electrical equipment or devices influence each other, such as interference between a television set, a GSM mobile phone, a radio and a nearby washing machine or power line. The purpose of electromagnetic compatibility (EMC) is to keep all these side effects within reasonable limits. EMC designates all existing and future technologies and technologies to reduce interference and enhance immunity. Electromagnetic Compatibility (EMC) directive 2014 / 30 / EU ensures that electrical and electronic equipment is not produced or affected by electromagnetic interference. Limit the electromagnetic radiation of the equipment ...

  The difference between FCC - SDoc certification and FCC - ID certification lies in whether the product has a wireless communication function. FCCID is suitable for products with wireless functions, such as mobile phones, tablets; FCCSDoc is suitable for ordinary electronic products, namely products without wireless function, such as displays, lamps, etc. Different products need to do different types of FCC certification.
