scope:

This standard contains the basic requirements for the construction and testing of Electrostatic Finishing Equipment. This standard does not include powder applicators that function using the principles of triboelectric charging of the powder particles.

The requirements of this standard apply to the following equipment types whereby the spray material originates from applicators of the automatic (reciprocator or robot) and manual (hand-held) type. This equipment is used for the application of ignitable liquid based spray material or dry powders using grounded spray material supply systems, or waterborne systems.

Electrostatic Finishing Equipment for use with waterborne spray materials using ungrounded spray material columns is also addressed by this standard. However, any reference to spark ignition testing is not applicable for these types of systems, as waterborne spray material is not considered to be an ignition hazard. Waterborne systems covered by this standard are examined for affording protection against electric shock, fire and injury where the spraying area is not a hazardous (classified) location. See definitions. Where it cannot be confirmed that the waterborne spray material is nonignitable, it should be treated as an ignitable liquid based spray material and the waterborne manual applicator shall be tested as "Nonincendive" to Section 4, and the waterborne automatic applicator as "Incendive" to Section 5 or "Nonincendive" to Section 4.

This standard anticipates the submittal of Electrostatic Finishing Equipment for use in an ambient temperature range of 32°F to 104°F (0°C to 40°C). Systems with operating parameters outside this temperature range will be the subject of special investigation.

Purpose

This standard serves as the basis for FM Approval of Electrostatic Finishing Equipment.
