It is a set of measures that are taken to prevent the damage of the electrical properties that cause electrical hazard to people such as safety, current and voltage. In particular, in the case of design and manufacturing faults in various electrical devices used in manufacturing plants and factories, the health of users using these devices may be compromised. This is not different for household electrical appliances. Therefore, their production needs to be inspected, measured, tested and avoided. To the devices electrical safety test devices. The availability and use of such devices in production facilities is important in terms of ensuring occupational safety.
In addition, authorized and equipped laboratories electrical safety tests It is made. There are numerous tests carried out in this sense. Most of them are EMC test, LVD test, grounding tests, insulation test, surface tension test, cable tension test, heating test and leakage current test. Also, insulation resistance test at operating temperature, insulation resistance test at ambient temperature, long term resistance test of the insulation DC voltage, high voltage test, electrical resistance test, input power and current test, moisture resistance test, lightning impact test, puncture voltage test, unusual work test , discharge test, superficial leakage test and tens of electrical tests are performed.
Electromagnetic Compatibility EMC testsThis is done to determine the electromagnetic energy that electrical and electronic devices emit into the environment during their work and prevent each other from working. It is expected that such devices will continue to operate in the electromagnetic environment without causing any interference and without being affected by any other interference. This is called electromagnetic compatibility. After the tests to be carried out, a certificate of conformity is given by the laboratories when it is determined that these devices work in accordance with the relevant legal regulations and published standards.
For low-voltage alternating current from 50 to 1000 volts, from 75 to 1500 for low voltage electrical and electronic equipment LVD testsAlthough, at first glance it is only test tests such as isolation test, high voltage test, leakage current test and ground line continuity test, it actually refers to many different tests. For example, testing of insulation intervals and surface leakage paths, temperature rise and warm-up testing, power measurement, protection against penetration of liquid and solids, humidification tests, air conditioning tests, mechanical tests and unusual work tests.
Among the tests performed within the scope of electrical safety tests RoHS tests There is also. The current regulations restrict the use or use of some elements and chemicals that are harmful and dangerous to human health and environmental conditions in electrical and electronic equipment. This application is accepted all over the world today.
Some heavy metals and components, such as lead, mercury, chromium or cadmium, fall within the scope of RoHS tests. These elements do not only threaten human health, but also cause environmental damage when they are not recycled and left uncontrolled in the environment. The scope of electrical and electronic products covered by RoHS tests was extended in 2013. Accordingly, large household appliances, small appliances, computer technologies and telecommunications equipment, consumer products, lighting devices including light bulbs and chandeliers, electrical and electronic devices, toys, entertainment and sports equipment, medical devices, monitoring and control instruments, automatic distributors and Other electrical and electronic products not in groups fall under the scope of RoHS tests.
However, IP Tests The IP Protection Rating (Ingress Protection Rating) is generally referred to as the world-class International Protection Rating, It is the levels used to measure the resistance of mechanical or electrical devices to water, dust or external impacts. These ratings are published by the International Electrotechnical Commission (IEC). Another purpose of these codes is to provide more detailed information about the marketed product.
The main IP tests are made according to the following categories: Resistance to Solid Objects, Protection Against Object Size, Resistance to Liquids, Protected against Access to Hazardous Parts, Mechanical Impact Resistance.
Businesses who want to take electrical safety tests and obtain the relevant certificates of conformity or require more detailed information on these issues, certification TÜRCERT Consult the Technical Control and Certification company.
