DeepLightTesting&Certification

  In the sales process of laser products, whether it is normal offline sales or online sales, safety issues will be involved.   Most testing of laser safety issues is defined by IEC standards. IEC 60825-1:2014 is laser product s  safety   testing standard, Part 1  is Equipment classification and requirements.     The D eeplight Tech can not only complete the IEC 60825-1:2014 standard test of laser products, but also complete the FDA standard 21 CFR 1040.10 test ing , u ntil obtaining FDA completed email and FDA listing for customers.   In the same way, laser products are sold in the U.S. market, and D eeplight Tech  can also help customers complete NRTL certification of laser products , one-stop completion.       The NRTL\IEC60825-1\FDA Standard   21 CFR 1040.10 laser products test ing  content briefly introduced:   1.CLASSIFICATION PRINCIPLES (1) Radiation of a single wavelength , Wavelength : λ: 532nm. (2) Radiation of multiple wavelengths , Laser product emits at two or more wavelen

  NRTL(Nationally Recognized Testing Laboratory) certification and UL standards testing is used for the safety certification of electrical and electronic products exported to the North American market. In general, safety certification in North American market is not mandatory, but most products exported to North American market will voluntarily apply for these certification and testing. Because consumers are very concerned about the safety of their products. Amazon and AliExpress aslo often require NRTL certification or UL standards testing for chargers, lithium battery products, and electronic products. UL60950 UL62368 UL1778 UL1786 UL2089 UL2743 UL588 UL 94… A product certified by NRTL or UL standards testing indicates that the product meets the requirements of one or more appropriate safety testing standards, easily obtain consumer trust in the product. Deeplight Technology has carried out NRTL certification and UL standards testing for many years and has rich experience. We will se

  Introduction to LoRa wan certification As a new communication method for the Internet of Things, LoRa is an ideal network configuration with the advantages of low power consumption and large-scale coverage. Since it is a communication method, there must be interoperability requirements between data terminals and base stations (gateways). Therefore, the LoRa Alliance requires that LoRa devices must meet the LoRaWAN protocol specification requirements. 2. LoRa wan certification regional test: (1) The certification requirements for terminal equipment in 863-870 MHz region of EU. (2) The certification requirements for USA + Canada 902-928 MHz regional terminal equipment. (3) The certification requirements for terminal equipment in Asia 923 MHz region, LoRa AS923 requirements are for products working between 915 and 928 MHz. Some Asian countries still have ISM bands in this range. As a result, LoRa technology has been more and more widely used in Asia. (4) The certification requirements f

  Bluetooth BQB certification is a routine projects now. Most of Bluetooth BQB certification are end product certification. For many end product BQB certifications, only the lowest layer RF testing +top layer application profiles testing are required, which is easy to testing. So, who will test the Buetooth protocol stack layer? Generally,Bluetooth chip companies\Bluetooth solution companies\Bluetooth protocol stack software development companies need testing Buetooth protocol stack layer. Deeplight Technology has a case which Bluetooth product need testing profile and RF to protocol. At present, the Deeplight Technology has begun to carry out the Bluetooth protocol stack BQB certification testing, which includes all the protocol layer testing such as BLE 2M rate\coded\stable modulation index\AoA\AoD\BLE audio… The Bluetooth BQB certification testing has the following layers according to the Bluetooth SIG: (1) The lowest Bluetooth physical layer:RF, RF-PHY. (2) Intermediate protocol st

  Wireless products test items include electromagnetic compatibility EMC test, RF radio frequency test, safety test, SAR test, etc. Among them, RF test is one of the important test areas, and the test cases is relatively large. We introduce the RF test content of BT\WIFI\GSM\WCDMA products. (1)Bluetooth and Wifi product RF testing (spectrum analyzer, simulated base station, power splitter, attenuator) (2)GSM RF test (spectrum analyzer, simulated base station, power splitter, attenuator) (3)WCDMA FCC RF test (spectrum analyzer, simulated base station, power divider, attenuator) Deeplight Technology Advantages： （1）We more than ten years of experience in handling PTCRB\GCF\JATE\BQB\Telec\JATE\LoRa\FCC\SAR\RF\OTA\EMC...product certification and testing, and the engineering project team can professional and quickly deal with such projects. （2）DeepLight has helped many listed companies successfully complete certification. （3）Our quotation will be preferential. （4）Our professional engineering

  Brief introduction of SAR The electromagnetic radiation of mobile phones and other wireless products has always been a matter of close concern to the public. What is the measure of this radiation? There is a term here called SAR. The full name of SAR is Specific Absorption Rate. It is the electromagnetic wave energy absorption ratio of mobile phones or wireless products. The meaning of SAR is the electromagnetic power absorbed or consumed per unit mass of human tissue, in W/kg. Basic requirements of SAR testing The ambient temperature is between 18°C and 25°C, and the liquid temperature change during the measurement process cannot exceed ±2°C. The environmental electromagnetic noise cannot exceed 0.012W/Kg. The tested wireless communication device cannot be connected to the local public communication network. The influence of reflection and auxiliary RF transmitter should be less than 3% of the measured SAR value. Basic preparation for SAR test (1) The dielectric properties of the ti
