Compliance Verification (Periodic Testing)
Equipment: An instrument or collection of instruments that provide an indication or measurement. It may or may not be repeatable or accurate. This equipment is typically used for indications of pass or fail.
Conductive Flooring Material: A floor material that has a resistance to ground of less than 1.0 x 106 ohms.
Dissipative Floor Material: Floor material that has a resistance to ground between 1.0 x 106 and 1.0 x ohms.
Groundable Point, Floor Material: A point on the floor material that is intended to accommodate an electrical connection from the floor material to an appropriate electrical ground.
Laboratory Evaluation Equipment: An instrument or collection of instruments that meet the critena of a standard or standard test method that provides a measurement that is accurate and repeatable. This equipment is typically used to qualify materials, devices or procedures prior to acceptance and under controlled conditions.
Point-to-Point Resistance: The resistance in ohms measured between two electrodes placed on any surface.
Resistance to Ground: The resistance in ohms measured between a single electrode placed on a surface and ground.
Resistance to Groundable Point: The resistance in ohms measured between a single electrode placed on a surface and a groundable point.
Static Control Floor: A permanently installed floor material such as tile, carpet, polymer, epoxy, or sheet flooring that controls static charges on personnel, equipment, or other objects contacting the floor material.
Static Control Floor Finish: A non-permanent coating periodically applied to floor surfaces that controls static charges on personnel, equipment, or other objects contacting the floor material.
Static Control Floor Mat: A movable island of material placed over existing flooring that controls static charges by grounding personnel, equipment, or other objects contacting the floor material. Static control floor mats may be checked either resistance to ground or point to point resistance. Conductive floor mats may be tested point to ground. A current limiting resistor may be used to connect the mat to ground. This may cause the readings to exceed 1.0 x 106 ohms.
4.0 PERSONNEL SAFETY
4.1 The procedures and equipment described in this document may expose personnel to hazardous electrical conditions. Users of this document are responsible for selecting equipment that complies with applicable laws, regulatory codes and external and internal policy. Users are cautioned that this document cannot replace or supersede any requirements for personnel safety.
4.2 Ground Fault Circuit Interrupters (GFCI) and other safety protection should be considered wherever personnel might come in contact with electrical sources.
4.3 Electrical hazard reduction practices should be exercised and proper grounding instwctions for equipment must be followed.
5.0 EQUIPMENT AND MATERIALS
5.1 Equipment Requirements
5.1.1 Resistance Measuring Meters
5.1 .1 . 1 The instrumentation may consist of either a power supply and current meter (ammeter), or an integrated instrument that combines these functions.
5.1.1.1.1 Use of Laboratory Evaluation Meters:
The meter(s) shall have an output voltage, while under load, of 10 volts (± 5%) for measurements less than 1.0 x 106 ohms and 100 volts (± 5%) for measurements of 1.0×106 ohms and above. The meter must be capable of making measurements from 2.0 x ohms (± 10% accuracy) to 1.0 x 1010 ohms (± 10% accuracy).
