Help enterprise non-contact infrared thermometer meet the requirements of electromagnetic compatibility!
Release date: 14:46, July 16, 2020

"During the epidemic period, people in various places need to" tick "wherever they go. This is the joke of many friends about the forehead temperature measurement. They should be pointed at their heads with guns every time. This is also the responsibility and obligation of each of us under the epidemic situation. However, as the key epidemic prevention materials, what kind of quality inspection procedures should be followed for the Ewen gun to be identified as qualified products and approved for production? Infrared temperature instrument For example, the key to the rapid development of special tools in Colleges and universities, such as the temperature beyond a certain group of people.

Let's talk about EMC (electromagnetic compatibility) that forehead temperature gun needs to meet in complex electromagnetic environment. As an artifact of collective temperature measurement, forehead temperature gun is rarely produced by enterprises at present, and the supply of products on various platforms is also less than demand. The reason for this situation is that the forehead temperature gun needs to meet the regulatory requirements of different regions when it enters the market of various regions. Let's summarize the testing standards of forehead temperature guns in China, the European Union and the United States.

Chinese general standards: GB 9706.1-2007 (medical electrical equipment Part 1 - General safety requirements); YY 0505-2012 (medical electrical equipment Part 1-2: General safety requirements; parallel standards: electromagnetic compatibility requirements and tests); GB / T 14710-2009 (medical electrical equipment environmental requirements and test methods); special standard: GB / T 21417.1-2008 (medical infrared thermometer Part 1: ear cavity type); referring to the above national standards, enterprises should formulate technical requirements suitable for their own products. EU CE certification en 60601-1:2006 / a1:2013 (medical electrical equipment Part 1: General requirements for basic safety and basic performance); en 60601-1-2:2015 (medical electrical equipment Part 1-2: General requirements for safety and parallel standards: electromagnetic compatibility requirements and tests); en 60601-1-11:2010 (medical electrical equipment - Part 1-11: General requirements for basic safety and essential performance - Concurrent standards: requirements for medical electrical equipment and medical electrical systems for use in domestic healthcare environments); ISO 80601-2-56:2018 (medical electrical equipment - Part 2-56: Particular requirements for the basic safety and essential performance of clinical thermometers for thermometry).

A small number of manufacturers may not choose the MDD Medical Equipment Directive, but choose those with relatively low test requirements and low certification threshold to test and certify according to the measurement equipment en61326-1 and en61010-1, which will not be detailed here. FDA 510 (k) certification iec60601-1:2005 + a1:2012 (medical electrical equipment Part 1: General requirements for basic safety and basic performance); iec60601-1-2:2014 (medical electrical equipment Part 1-2: General requirements for safety: electromagnetic compatibility requirements and tests); iec60601-1-11:2015 (medical electrical equipment. Part 1-11: General requirements for basic safety and essential performance. Parallel standards: home and abroad) Requirements for medical electrical equipment and medical electrical systems for use in healthcare environments); iso80601-2-56:2018 (medical electrical equipment - Part 2-56: Particular requirements for the basic safety and basic performance of clinical thermometers for thermometry).

In order to facilitate the use and portability of forehead temperature guns, batteries are usually used for power supply, so the test items of power line (signal line) port are exempted. Only the shell port test is required, including radiated disturbance test, radiated immunity test, power frequency magnetic field immunity test and electrostatic discharge immunity test, Domestic as follows: the radiated disturbance test is conducted according to GB 4824 standard, which belongs to class B equipment of group I, and the test frequency range is from 30MHz to 1GHz. Radiated disturbance test arrangement radiation immunity test shall be conducted according to YY 0505-2012. Electromagnetic wave with frequency from 80MHz to 2.5GHz, 1kHz, 80% AM modulation and effective value of 3V / m shall be used for test.

It should be noted that when CE certification is carried out according to en 60601-1-2:2015, electromagnetic wave with frequency from 80MHz to 2.7ghz, 1kHz, 80% AM modulation and effective value of 3V / m shall be used for test. In addition, the en 60601-1-2:2015 also requires the use of wireless communication equipment to test the radiation immunity of the sample up to 6 GHz at a distance of 1 meter. For example, use walkie talkie, smart phone, 2.4G and 5g dual channel WiFi router, etc.: radiation immunity arrangement note: in the process of radiation immunity test, it is necessary to observe the real-time information of the tested object, so it is necessary to continuously press the start button of forehead temperature gun during the test process: press YY for power frequency magnetic field immunity test 0505-2012 standard test, need to use 3A / M magnetic field level test, in the EU CE certification, need to carry out the test of 30a / m level. Power frequency magnetic field immunity test arrangement electrostatic discharge immunity test shall be conducted according to YY 0505-2012 standard, and 8Kv air discharge and 6kV contact discharge shall be used for the test. When EU CE certification is conducted, contact 8Kv and air 2,4,8,15kv level tests shall be conducted.

A certain type of contactless Infrared temperature instrument During the EU CE certification, there are problems in RF radiation immunity test: test standard: IEC 60601-1-2:2015 unqualified items: radiation immunity, 80m-2.7ghz, 1kHz, 80% am, 3V / M unqualified phenomenon description: Antenna horizontal direction, reference heat source temperature 37.4 °. If the temperature is between 1 500 MHz and 1 500 MHz, it is not qualified. If the temperature is not up to the standard, the accuracy of the factory is not required. 2500-2700 MHz, 40-42 ℃, unqualified. In the vertical direction of antenna, the reference heat source temperature is 37.4 ℃. 330-350 MHz, 37.4 ℃ gradually increased to 38.4 ℃, unqualified. 520-560 MHz, showing 37.4 gradually warming up to 39.0 ℃, unqualified. 1200-1388 MHz, 2522-2700 MHz, 36.7 to 39.1 ℃, unqualified.

frequently-used Infrared temperature instrument It can be divided into Infrared thermography rapid temperature screening instrument And infrared thermometer. Infrared thermography rapid temperature screening instrument It can be used for large-area monitoring in public places with dense flow of people, automatically track and alarm high-temperature areas, and cooperate with visible light video to quickly find and track people with high body temperature. Infrared thermometer can be divided into infrared ear thermometer and infrared forehead thermometer. Infrared thermometer is simple in equipment, easy to use and affordable in price. It can measure the temperature of personnel in turn and quickly.
