EN 60068-2-78 Mold Growth Resistance Testing
The EN 60068-2-78 standard specifies procedures to determine the resistance of materials and products to mold growth under controlled environmental conditions. This test is crucial for ensuring that electrical and electronic equipment, as well as other components used in railway and transportation systems, can withstand exposure to moist environments without compromising their functionality or safety.
The process involves exposing specimens to a high-humidity environment followed by a temperature cycle designed to simulate the natural conditions under which mold growth typically occurs. The duration of this cycle is critical and must be tailored based on the specific material being tested. For instance, some materials may show signs of mold growth after just 3 days, while others might require up to 21 days.
Before initiating the test, specimens are prepared according to prescribed standards. This includes cleaning the samples thoroughly to ensure no pre-existing molds or debris interfere with the results. The test chamber is then calibrated and maintained at precise temperature and humidity levels as defined in the standard.
The apparatus used for this testing typically consists of a controlled-environment chamber equipped with sensors capable of monitoring both temperature and relative humidity accurately within narrow tolerances. Humidity levels range from 95%RH to 100%, while temperatures vary between -20°C and +85°C depending on the specific requirements outlined in EN 60068-2-78.
Once the specimens have been exposed to these conditions for the specified time period, they are examined visually for signs of mold growth. Any visible fungal colonies are recorded and documented as part of the final report. The results provide valuable insights into how well different materials perform in humid environments, which is essential information when designing products intended for use in railway or transportation settings where exposure to moisture cannot be avoided.
It's important to note that this testing method does not guarantee protection against mold growth but rather provides a reliable measure of material resistance. By adhering strictly to the procedures outlined in EN 60068-2-78, laboratories can ensure consistent and accurate results across multiple trials.
