Capabilities
The SH&A laboratory performs several levels and types of measurements to meet industry and corporate standards. Every material or product submitted for analysis is properly prepared and preconditioned before tests are conducted. All tests are carried out under controlled conditions to industry or the client's requirements.
Flooring: Charge Generation and Probability Analysis using published SH&A methods, and resistance characterization to the following standards and guidelines:
ESD-STM 7.1-2001 Resistance Characterization of Floor Materials
ESD STM 97.1-1999 Floor Materials and Footwear – Resistance in Combination with a Person
ESD STM 97.2-1999 Floor Materials and Footwear – Voltage Measurement in Combination with a Person
as well as NFPA-99 and ASTM F-150 and others
