Increased requirements for radiated EMI testing by electronics manufacturers and testing laboratories have created the need for more frequent and accurate testing of materials. This is in accord with the emanation standards laid out in Part 15, Subpart J, of the FCC Rules and Regulations.

Because of weather limitations testing in open filed sites has become impractical. Wood structure enclosures have inherent limitation because of moisture retention in wood components and interference produced by metal fasteners.

To service the need for all-weather, and more accurate testing, Enduro Systems, Inc. Composite Systems has developed Tuff-Span Structural Plastic Building Systems. Constructed entirely of fiberglass-reinforced plastic (FRP) components, Tuff-Span EMI Test Enclosures provide the ideal test environment for the most sensitive and sophisticated electronic equipment. All building materials above the ground plane are non-conductive, non-magnetic, and R.F.-transparent.

Test results in these facilities are absolute and comply with FCC open filed test requirements.

Enclosures are available in sizes which permit 3-, 10-, and 30- meter testing as well as accommodating large diameter turntables.

TuffSpan structural components include FRP roofing and siding panels, FRP structural beams, FRP doors and vents, and even FRP fasteners. Continuous fiber reinforced Tuff Span provides far greater structural performance than conventional chopped strand fiberglass. Through optimum placement of continuous, high strength reinforcing fibers, and exclusive pultrusion process, and shapes which enhance structural capacity, TuffSpan components are engineered as one-to-one structural replacement for traditional materials used in conventional building construction.

TuffSpan FRP materials require no maintenance and are totally corrosion resistant. They are also fire retardant with a Class 1 Flame Spread Rating. Panels are available in various architectural rib profiles with integral custom colors. Exterior panels can also be translucent to permit natural light transmission.

Enduro Systems, Inc. Composite Products Systems is the experience and qualified source for FRP-constructed EMI Test Enclosures. Structural design by our in-house staff of certified Professional Engineers is based on reliable and proven engineering practice. Installation assistance is available.
