ATmosphères EXplosibles, or the "equipment for explosive atmospheres-ATEX directive", is one of 32 technical and regulatory directives mandated by the Conformite Europeenne (CE) mark. When it comes to product and industrial safety, human health, and consumer and environmental protection, the relevant technical regulations (i.e. directives) are general, minimum and acceptable requirements for all EU member states.
On January 21, 2019, the NB-IoTSIM7020 series module (SIM7020C/SIM7020E/SIM7020G), produced by SIMCom, has obtained the ATEX 2014/34/EU authentication certificate, which is based on EN/IEC60079- 0 general standard, and EN/IEC 60079-11 intrinsically safe standard in explosive atmospheres among EN/IEC60079 series standards. The CE explosion-proof certification marks are shown below:
The meaning of the characters of the explosion-proof marks in this ATEX authentication certificate: Ex mark is ATEX certification; II is non-mining equipment; 1 is the highest protection level Category 1 explosion-proof equipment in ATEX directive. This equipment is suitable for Class IIA, IIB and IIC gases, as defined in EN/IEC60079-10-1. The explosion-proof areas of explosive gas mixtures are in Zone 0, Zone 1 and Zone 2. The product explosion-proof type is II 1G Ex ia IIC Ga, and the ambient temperature of the product is -40 ° C ~ +85 ° C.
Obtaining the above certificate and CE mark indicates that the SIM7020 series has met the technical requirements of the European Union for applying equipment in potentially explosive environments, including basic health and safety requirements, and conformity assessment procedures that must be followed before the equipment is launched in the European market within its scope of use.
The SIM7020 series is a multi-band NB-IoT wireless communication module, packaged with a 42 PIN LCC. It has a wealth of hardware interfaces, including serial ports, GPIO, ADC, etc., so the module has good extensibility. The package is compatible with the SIM800c module, which minimizes the customer’s R&D time and accelerates the launch of customer products.
The SIM7020 module is one of the main products of SIMCom’s LPWA product line. It is an ideal solution for low-latency, low-power, and low-throughput for IoT applications such as meters, remote control, asset tracking, remote monitoring, telemedicine, and shared bikes.
TÜV SÜD Industrial Products Department’s explosion-proof certification service relies on the complete process closed-loop services of TÜV SÜD’s explosion-proof product testing laboratory, for evaluation, analysis, and certification in order to fully assist domestic and foreign explosion-proof equipment manufacturers in improving production and operational efficiency, reduce costs, control risks, and then enter and comprehensively explore the global explosion-proof product market based on one-stop services by TÜV SÜD explosion-proof products multi-country certification (ATEX 2014/34/EU, IECEx, Hazloc, etc.).
In terms of personnel training, the IECEX 05 Certified Persons Scheme is recognized by the International Electrotechnical Commission for the capacity of operators in the explosive regional environment. Trainees will receive the IECEx05 qualification certificate through the training of TÜV SÜD explosion-proof experts and pass the corresponding unit exam, which is also published on the IECEx official website.
In addition, TÜV SÜD can also provide a number of services for explosion-proof equipment end users in explosive hazardous sites, such as explosion-proof area pision, equipment selection for the area and explosion-proof safety assessment etc. to continuously improve international safety requirements for enterprises in explosive hazardous sites and reduce the potential safety hazards in industrial production.
