These requirements cover the test methods for measuring the fire performance of sheet plastics used in semi-conductor wet bench tool construction.

Plastic materials that are classified as Class 1 or Class 2 demonstrate limited fire propagation without the use of sprinklers.

Variations from the construction or conditions that are tested are capable of substantially changing the performance characteristics of the plastic.

This standard is not intended for evaluation of small plastic components used in semi-conductor tool constructions such as tubing or wiring.

This standard does not measure mechanical or structural properties of plastic, and this standard does not measure the hazards from the smoke generated by the plastic material.

A product that contains features, characteristics, components, materials, or systems new or different from those covered by the requirements in this standard, and that involves a risk of fire or of electric shock or injury to persons shall be evaluated using appropriate additional component and end-product requirements to maintain the level of safety as originally anticipated by the intent of this standard. A product whose features, characteristics, components, materials, or systems conflict with specific requirements or provisions of this standard does not comply with this standard. Revision of requirements shall be proposed and adopted in conformance with the methods employed for development, revision, and implementation of this standard.
