Control Material Qualification

Affinity has opened a laboratory facility in order to provide testing of ESD Control Materials at the required humidity levels to satisfy the requirements of material qualification for ANSI/ESD S20.20. Beginning in 2010, it is necessary to show proof that the materials used in an ESD control program meet the specification requirements of S20.20 when tested according to ESD Association test methods. Affinity has the ability to provide 3rd party testing of most of the materials used in an ESD Control Program, including the following:

  • Surface and Volume Resistance/Resistivity of materials and items according to ANSI/ESD STM11.11 and ANSI/ESD STM 11.12
  • Worksurface resistance tests according to ANSI/ESD STM4.1
  • Floor material resistance tests according to ANSI/ESD STM7.1
  • Footwear resistance tests according to ANSI/ESD STM 9.1
  • Foot Grounders according to ANSI/ESD SP 9.2
  • Flooring and Footwear in combination with a Person – Resistance, according to ANSI/ESD STM 97.1
  • Flooring and Footwear in combination with a Person – Voltage Generation according to ANSI/ESD STM 97.2
  • Wrist strap electrical properties according to ANSI/ESD S1.1
  • Garments according to ANSI/ESD STM2.1
  • Ionization testing according to ANSI/ESD STM3.1
  • Seating resistance tests according to ANSI/ESD STM 12.1
  • Glove resistance test according to ANSI/ESD SP 15.1
  • Quotes for material testing are available upon request and testing generally can be completed within 10 days of material receipt. Humidity conditioning requires a minimum of 48 hours each at moderate and low levels. Material testing takes place in the conditioned environment in accordance with the individual Standards, Standard Test Methods and appropriate Standard Practices.

    In addition, Affinity can provide application related testing of materials, items and products in those instances where test methods are not specifically established. Affinity also provides significant capability in evaluation of triboelectric charge generation to help establish process risk. Evaluation of triboelectric charge generation is the first step in developing reliable electrostatic mitigation techniques suitable for any given application. Affinity has a good understanding of electrical fields and associated risk related to charged process essential insulators.
