Ease of use The goal of the developers of the S20.20 standard was to simplify the process of understanding and using the document and implementing a program that would meet the standard. Although Handbook 263 is very complete, it doesn't mesh well with MIL-STD 1686, and trying to extract what you need for your program can prove difficult. The S20.20 document eliminates that problem by following each paragraph of requirements with a guidance section that explains how you might meet those requirements. The guidance section explains how staff members should track and verify the performance of their grounding devices using constant-monitoring devices and logs. However, users still have questions about the standard, and most of those questions center on the table in the S20.20 document.
Some users find parts of the table difficult to interpret.
In the section related to a protected area, for example, the table lists work surfaces, wrist-strap cords, flooring, and other ESD control tools as optional. Some people ask which of the ESD-protection techniques they should use. Actually, it's up to them to decide. The table lets people choose from the individual items based on what they plan to do.
