Series 81 Shielded Rooms for Government
​​​​​ETS-Lindgren's Series 81 shielding system is the most commonly specified construction for NSA 65-6/NSA 94-106 and MIL-STD-285/IEEE 299 testing requirements.

 

 


​​​​​ETS-Lindgren's Series 81 shielding system is the most commonly specified construction for NSA 65-6/NSA 94-106 and MIL-STD-285/IEEE 299 testing requirements. These shielded enclosures have modular panels, meaning that enclosures can be built to almost any dimensional configuration. Thirty-six standard formations are available, or we can custom design a configuration that best fits your needs.

In the heart of the shielding system are the 1.9 cm (.75 in) thick dimensionally-stable cores,​​ which are laminated on both sides with 28-gauge sheet steel. (Cores meet ANSI A208.1 specifications.) The steel laminate provides the best attenuation to magnetic and electric fields​​ and plane waves

Panels are joined together with a one-eighth-inch "hat & flat" clamping system. No special tools are required for construction. Enclosures can be erected, dismantled, and moved to another location as needed. Enclosures are self-standing and require no attachment to the parent building.

Key Product Information


Materials

Our Series 81 shielded Enclosures feature a steel lining as steel is excellent for reflecting and attenuating EMI/RFI signals. The Series 81 offers optional gauge thickness of 28- or 11-gauge, the advantages of high shielding performance, durability and ideal electrical continuity.

Galvanized steel also provides excellent low frequency AC magnetic field attenuation characteristics.

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

The 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 Shielded Enclosures​ consist of shielded modular panel sections that are assembled with a clamping system into a self-supporting enclosure structure. Sheets of 28-gauge galvanized steel are laminated to a 1.9 cm (.75 in) high-density particle and/or plywood board core. Each panel section provides excellent stability to airborne moisture-induced warping and structure strength that lends to its rugged structural design.

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 Shielded 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.
