The testing of wrist straps, foot grounders, ESD shoes and other personnel grounding devices is a vital part of any ESD Control Plan. Why you ask? The human body is one of the biggest generators of static electricity, so it is important that we are kept grounded.
However, using wrist straps or foot grounders is not enough; all personnel grounding devices have a finite lifetime, we need to know when its lifetime ends causing the person to be no longer grounded. Per IEC TR 61340-5-2:2018, clause 22.214.171.124 Verification frequency, “A ground cord, whilst being worn, is subjected to thousands of stretch/bend cycles each day and the conductive wire(s) in the ground cord will eventually break”. The personnel grounding device could stop functioning at any point and will most likely not be visible to the human eye. This is where Personnel Grounding Testers come in, they verify the functionality of an operator’s wrist strap and/or footwear.
Now we have covered the importance of regular verification testing, we need to consider the different types of testers available, which one is right for your application and what the IEC 61340-5-1 standard tells us about personnel grounding testing.
