UL62368-1 is a safety regulation standard based on the HBSE danger protection engineering principle. Th is   concept is slightly different from the current regulation standard, which covers the danger to people and the environment in information products and audio and video equipment, as well as the corresponding danger protection. In fact, UL62368-1 is a combined version of AV audio UL60065 and IT information UL60950.

  Head-mounted VR g lasses display device mainly close people's vision and hearing to the outside world, Guid ing   user s   to create a sense of being in a virtual environment. G enerally such products to be exported to the United States must be transacted   the FCC test report.

  Generally, environmental reliability tests are divided into three categories: mechanical environment test, climate environment test and comprehensive environment test. Mechanical environment test mainly includes mechanical vibration, mechanical impact, drop, collision, steady-state acceleration test, climate environment test mainly includes the test of temperature, temperature and humidity test, pressure test, water test, test, salt spray test, sand dust test, gas corrosion test, including comprehensive environment pressure comprehensive test, temperature vibration, temperature and humidity vibration comprehensive test, temperature pressure humidity comprehensive test, etc.

  Hot and humid environment generally exists in the whole life cycle of the transportation, storage and use of electronic products. Under the influence of hot and humid environment, the insulation materials and metal surfaces in electronic products will adsorb water vapor, leading to the degradation of products. At the same time, under the joint action of humidity, temperature and electrical stress, it will cause electrochemical reaction and metal corrosion, resulting in the insulation resistance of electronic equipment, leakage increase, serious flying arc, breakdown circuit damage and other phenomena. What is the   hot and humid   test Hot and humid   test can be divided into constant hot and humid   test , alternating hot and humid   test, is the environmental stress of temperature stress and humidity stress two environmental stress, need to use constant hot and humid   test chamber   or alternating hot and humid   test chamber ,   ef...

 What is Plug and Pull Force Testing The test method of plug and pull force is an experimental method to test the performance of the connector . This method mainly by simulating the actual use situation, p lug and pull the connector multiple times, in order to evaluate the reliability and durability of the plug and pull   performance. Test principle and purpose Its   test method is to insert and pull the connector by applying a certain force and frequency, and observe the change of the plug and pull force under different times. Through this test evaluates the performance of the connector to determine its reliability and durability in practical use. The plug   and pull test method is a common, which is widely used in electronics, communication, aerospace and other fields. Through th e   method, we can effectively evaluate the plug and pull   performance of the connector, provide the basis for product design and selection, and ensure the good reliability and ...

  RCM logo is led by the Queensland government and Victoria government .  The purpose is to verify the combination of safety regulations and EMC .   A s you know, Australia's safety (SAA) and C-TICK is separate certification, SAA application can be different national factories and traders, t he filing subject of C-TICKR is the legally registered company in Australia. In the application process of RCM, the legal entity of Australia is required, that is, RCM is a certification mode that needs to be guaranteed by an Australian company. For most products ,  need to obtain SAA certificate and EMC test report, can register as RCM certificate, not instead of SAA certification, just added requirements to EMC on the basis of SAA certification, for the non-mandatory electrical product safety, can not apply for electrical safety certificate, but directly use electrical safety test report + C-TICK test report (EMC report), if it is mandatory product, must first obtain electrical...

  SAA certification can be said to be mandatory certification in Australia, which is in Australia and New Zealand. Australia and New Zealand are two less populated countries, with a population of 23 million, but the consumption power is very high . The widely recognized SAA (Standards Association of Australia) is actually a standard research institute, responsible for the formulation and revision of standards. The electronic and electrical products which e nter Australia (including Australia and New Zealand) must pass the certification, put on the certification certificate number on the product, to legally enter the sales in Australia. Licensing agency: Currently, the SAA issuers are SAI, DOIR (Q number), and DOFT (N number). In general, the application cycle for Australian SAA certification for common IT lighting products is 3-4 weeks. If the product quality is not up to the standard, the date may be extended. Submit the report to Australia for review   need to provide t he S...

  What is the UL62368-1? The UL 62368-1 is the latest international product safety standard, covering audio-visual, consumer electronics and information technology products, and will completely replace the current UL60950-1 and UL60065 in the next few years. Traditional product safety standard is the summary of past bad experience and induction: passively wait for the new technology to have an accident in the market before introducing solutions into regulations .   S ince   it  is based on the accident is absolutely slower than the accident, so the traditional standard development always with product innovation, even often let a person feel standard provisions limit hindered the development of science and technology products. UL62368-1 abandon the past Lock the Stable Door After the Horse haseen Stolen thinking, using Hazard-Based Safety Engineering (HBSE) mode of thinking, no matter how the technology change from the application of energy, and all kinds of energy so...

UL2056 Test reports generally contain the following tests: Electrical test Mechanical testing drop test Squeeze test environmental testing waterproof test Dust test For mobile power supplies sold on Amazon's e-commerce platform, UL2056 certification is usually mandatory .

  Lamp reliability Salt spray test is an environmental test used to assess the corrosion resistance of lamps and their materials in a salty wet environment. This test usually simulates the corrosion conditions in a marine environment or an industrial polluted environment to ensure that the lamp can resist corrosion in practical use and maintain its function and appearance. During the test, the lamp sample is placed in a closed test room, where a certain concentration of saline solution is continuously sprayed to form a salt spray. Testing usually lasts for a certain period of time, depending on the test requirements and product standards.

  Tensile Testing Machines is a kind of instrument used for measuring the geometric parameters of materials (metal, plastic, fiber, etc.) and static dynamic mechanical characteristics under tensile load. Tensile testing machines through the opening of the sample across (to determine the size and shape according to the standards or specifications), with the tensile strain stress into meaningful numerical results, in order to accurately judge and analyze the tensile properties of various materials. Now let's take a look at the steps of using the Tensile Testing machine The use steps are as follows: Preparation: fix the material sample to be tested on the test machine, and adjust the fixture and sensor of the test machine. Set test parameters: set mode, speed, range for testing. Start the test: Start the test, the test machine will apply force to the material, and record the test data.
