At the beginning of the last century, a xenon lamp aging test chamber appeared in the world. It is composed of a carbon arc lamp as the light source, the lamp tube is vertically placed in the center of the instrument, and is surrounded by a filter system and a rotating sample frame. The test sample is installed facing the light source and rotates around the central lamp like a conveyor belt. After...
Assembly Security Test A flush receptacle having a 5-15R,5-20R,6-15R, or 6-20R configuration is to be mounted in the fixture described in Figure 124.1, and 50 lbf (220 N) is to be applied, as shown in Figure 124.2, for a period of 10 s by means of a push-out tool inserted into the slots of the receptacle. The push-out tool required for configuration 5-15R is to be as shown in Figure 124.3. Recepta...
The high and low temperature humidity test chamber, also known as the temperature shock test chamber and the thermal cycle chamber, is a device used to test the performance of products under high temperature, low temperature, and humidity environments. It is widely used in industries such as electronics, electrical appliances, automation instruments, aerospace, and automotive. The high and low tem...
Household power supply specifications will vary by region, but generally speaking, voltage values are usually between 100V and 240V, while the most common frequency values are 50Hz and 60Hz. Factories using polyphase power will have more differentiated power supplies with higher voltages and more specialized plugs and sockets for larger equipment, but will still use the general power supplies show...
With the continuous development of technology, various electronic devices are becoming more and more widely used in our lives. Electronic devices usually need to be tested in a controlled environment to ensure their functionality and reliability. Walk-in dust test chambers are commonly used testing equipment that can perform dustproof performance tests on electronic devices according to the IP5X d...
Switches MANUALLY OPERATED MECHANICAL SWITCHES which -control currents exceeding 0,2 A r.m.s. a.c. or d.c., and/or – have voltage across the open switch contacts exceeding 35 V (peak) a.c. or 24 V d.c. shall meet one of the following requirements: a) The switch tested as a separate component, shall comply with the requirements and tests of IEC 61058-1, whereby the following applies: – ...
IEC 60529 describes a system for classifying the degrees of protection provided by the enclosures of electrical equipment. Whilst this system is suitable for use with most types of electrical equipment, it should not be assumed that all the listed degrees of protection are applicable to a particular type of equipment. The manufacturer of the equipment should be consulted to determine the degrees o...
In order to achieve reproducibility, temperature tests must be designed in such a way that the highest or lowest temperature reached at a certain point in the high and low temperature test chamber is the same, regardless of the laboratory in which the test is conducted. For test designs with a shorter duration compared to the time required for the test sample to reach temperature stability, the fo...
Introduction Electromagnetic compatibility (EMC) is significant in the field of industrial automation, where continuous production processes are essential for success. Numerous electronic devices coexisting in industrial settings may cause electromagnetic interference (EMI) and interfere with the efficient operation of automated systems. In order to properly evaluate and remedy EMI concerns in ind...
