Static Control Testing
Static Control Testing, Training and Seminars
We offer various testing options for static control situations:
- Resistance (Ohms / Ω), e.g. Resistance-to Ground/Earth, Point-to-Point, for common grounding of personnel and equipment.
- Body Voltage (V / kV), e.g. Human Body Model (HBM) Walk Test, to measure the static generation and retention of an electrostatic charge when walking across any given floor with any given footwear.
There is more than meets the eye when it comes to testing and understanding of static control properties, we need to understand exactly what properties are required.
These are the properties that we are concerned with when it comes to static control:
- Antistatic - minimal retention of an electrostatic charge
- Low Charging - minimal generation of an electrostatic charge through the tribocharge effect
- Conductive - the ability to conduct a charge away through a low resistance material, e.g. <1 x 106Ohms
- Dissipative - the ability to conduct a charge away through a relatively higher resistance, e.g. <1 x 109Ohms
- Insulative - a resistance that is so high that grounding/earthing is ineffective or impossible
Here are some of the most common Standards that are referenced for static control flooring and grounding of personnel with appropriate footwear:
- Static Control Standard IEC61340-5-1, sub-Standards:
- IEC61340-4-1, Resistance-to-Ground (RG)
- IEC61340-4-5, Human Body Model (HBM) Voltage Walk Test
- IEC-TS-61340-5-4, Compliance Verification
- Static Control Standard ANSI/ESD S20.20, sub-Standards:
- ANSI/ESD STM 7.1, Resistance-to-Ground (RG)
- ANSI/ESD STM 97.2, Human Body Model (HBM) Voltage Walk Test
Note: IEC61340 and ANSI/ESD S20.20 are considered technically equivalent.
