Key Product Information


Performance

Series 81 shielding provides excellent EMI/RFI shielding effectiveness and is the most commonly specified shielding for NSA 65-6/NSA 94-106 testing requirements. Series 81 delivers high performance attenuation over a broad frequency range and complies with a variety of other specifications including:

  • Federal Specification SS-A-118B: Flame Resistance Test 

  • ASTM E84-81-A: Test for Surface Burning Characteristics of Building Materials 

  • ASTM E90-83: Recommended Practice for Laboratory Measurements of Airborne Sound Transmission Loss of Building Partitions

Series 81 also complies with Universal Building Codes (UBC) and can be assembled in the most stringent seismic zones. Combining performance and value, Series 81 meets a wide range of critical testing needs.

Construction

Series 81 panels are joined together with an extruded “hat and flat” and “cove” clamping system, to provide uniform and consistent pressure contact against the shielded panel mating surfaces. These structural clamping sections are zinc-plated to resist corrosion and are joined with self-taping zinc-plated fasteners,​​ spaced 10.16 cm (4.0 in)​ on center to ensure a secure shield. The corners of the shielded enclosure are secured with precision-machined trihedral end cap sections.

To maintain electrical isolation, a 6-mil dielectric vapor barrier and 3.175 mm (.125 in)​ dielectric underlayment are placed beneath the shielded floor panels. Counter-sunk floor screws in the clamping system ensure a smooth floor surface. Attractive vinyl floor tiles are applied with adhesives over the exposed steel surface as a durable wearing surface. In addition, Series 81 enclosures can be converted into a ferrite-lined and/or conventional absorber-lined anechoic chamber. This feature makes it a truly flexible shielding solution.

Door System

​Series 81 comes with a choice of two door systems. A Single Knife Edge (SKE) door offers a two-point latching system and Recessed Contact Mechanism (RCM) with enclosed beryllium contact fingers. The Double Electrical Contact (DEC) door system employs a three-point cam latching system with heavy gauge phosphor bronze contact fingers. Both door systems can be equipped with fully- or semi-automatic latching devices for areas of high usage, or where ease of accessibility is a concern. All enclosures can be fitted with a variety of other customized access door systems for personnel and equipment, enabling users to meet a variety of operational, security and extended shielding performance objectives.
