Salt spray test against LED light according to IEC60068 and ASTM-B117

LED lights, like many other electrical devices, may be tested for their resistance to corrosion by being subjected to salt spray testing. The salt spray and salt fog that may be seen in coastal areas will be replicated in this test to represent the corrosive effects of the environment. IEC60068 and ASTM-B117 are only two examples of the many international standards that outline the protocols and criteria for salt spray testing.

The International Electrotechnical Commission (IEC) has established the IEC60068 standard for the environmental testing of electrical and electronic goods. The salt spray test is only one of several used to determine how well electrical items hold up under varying conditions. The temperature, humidity, salt concentration, and length of time for salt spray testing are all specified in IEC60068.

ASTM-B117 is an American standard for testing the durability of electronic and electrical goods against corrosion. In-depth instructions and prerequisites for performing salt spray experiments are included. The temperature, humidity, and salt content, as well as the length of time, are all specified in ASTM-B117.

The following procedures may be used to perform a salt spray test on LED lights in accordance with IEC60068 or ASTM-B117:

• LED lights should be mounted on a test board or fixture before testing. Cleaning and drying the test items before analysis will eliminate any residue or impurities that might skew the findings.
• Prepare the test chamber The salt spray test chamber must be prepared in accordance with the manufacturer's instructions and the required test parameters, including the temperature, humidity, and salt concentration.
• Salt spray is applied by atomizing salt water using a nebulizer or spray nozzle device, which then sprays the resulting fine mist over the test specimens. In order to meet the standard, the test specimens must be subjected to the salt spray for a minimum of 24 hours and a maximum of 48 hours.
• Check up on the test samples to see whether they've changed in look or performance. You may do this by keeping an eye out for fluctuations in brightness, color, and other performance metrics.
• Examine the test specimens to ascertain the level of damage or deterioration once the test has been finished. Examining how well and for how long LED lights hold up in a salt spray environment may need a combination of optical and electrical testing.

Finally, the salt spray test is an essential tool for evaluating the efficacy and longevity of LED lighting in severe coastal conditions. The LED lights' performance and longevity in corrosive environments may be improved by exposing them to a controlled environment that mimics the impacts of salt spray, salt fog, and other corrosive materials. With the use of the salt spray test chamber, manufacturers can verify that their LED lights are built to withstand the harsh conditions of their intended environment, as specified by international standards like IEC60068 and ASTM-B117.
