FM4910 is the fire retardant property standard established by Factory Mutual System, a worldwide industrial insurance organization, for materials used in clean room applications. One of the major causes of delay in the chip manufacturing process is contamination. Contamination from a fire, no matter how small, could potentially put a chip maker out of business for weeks, if not permanently. Now, wet-bench manufacturers and users can apply the cleanroom protocol to develop plastic materials and equipment capable of resisting fire, emitting little, if any smoke, and producing little, if any, corrosive by-products. Materials passing the cleanroom protocol, subsequently, can be listed in the Approval Guide, a publication of FM Approvals.
