An STM7.1 floor resistance test report documents the measurements, the flooring system tested and the conditions under which testing took place. ANSI/ESD STM7.1-2020 specifies the required information (section 6.3), including additional documentation for installed floors and any departures from the method’s specified conditions.
STM7.1-2020 is an ESD Association standard test method (STM) for electrostatic discharge (ESD) flooring, approved by the American National Standards Institute (ANSI).
What every report includes
Section 6.3.1 of STM7.1-2020 requires the report to include:
- all values in ohms for resistance to groundable point and resistance point-to-point
- the test voltage
- the test date
- the temperature
- the relative humidity at the time of testing
- the actual duration of conditioning
- the test equipment used
- all components of the flooring system tested
- the substrate (supporting material) to which the flooring sample is applied
- a summary of the test data giving the minimum and maximum values obtained
Diagram for applied or installed results
For applied or installed results, STM7.1-2020 section 6.3.2 requires the report to include a diagram showing the approximate electrode positions and ground connections used.
Departures from the specified conditions
If conditions other than those specified in the method are used, STM7.1-2020 section 6.3.3 requires them to be reported. The method gives a flooring system installed to a stainless steel substrate as an example of an unusual condition that must be reported when it is used.
Frequently Asked Questions
STM7.1-2020 section 6.3.1 requires all resistance-to-groundable-point and point-to-point values in ohms, test voltage, test date, temperature, relative humidity at testing, actual conditioning duration, equipment used, every component of the flooring system tested, and the substrate to which the flooring sample is applied. The report must also summarize the minimum and maximum values obtained.
For applied or installed results, STM7.1-2020 section 6.3.2 requires a diagram showing the approximate electrode positions and ground connections used.
Yes. Under STM7.1-2020 section 6.3.3, conditions that differ from those specified by the method must be reported when used. A flooring system installed to a stainless steel substrate is one example given by the method.
