TITLE: Absorber Replacement for VESDA Pipe Install Enter

Requesting Laboratory / Division / Group:

Communications Technology Laboratory RF Technology Division Electromagnetic Fields Group 672.02

Scope of Work:

The Electromagnetic Fields Group is in need of the replacement of radio-frequency (RF) absorber on the ceiling of an anechoic chamber, in conjunction with an install of a new VESDA pipe. This scope of work includes the removal of existing absorber, allowing a VESDA pipe to be installed on the ceiling of the chamber, then installing new absorber over top of the VESDA pipe. This includes modifying the absorber on-site to accommodate the VESDA pipe. This work must be coordinated with the contractor installing the VESDA pipe to minimize down-time.

Objective(s):

Existing RF absorber in the Wing 6 anechoic chamber will be replaced with new absorber, in conjunction with the install of a new VESDA pipe. This will be coordinated with the VESDA contractor to minimize down-time of the chamber. The outcome of this work will allow a VESDA air sampling pipe to be installed to fix the fire suppression system, and to restore the anechoic chamber to its previous performance.

Enter Details

General Requirements:

New RF absorber will be provided by the contractor and be ready at the time of the VESDA pipe install. The RF absorber will be certified to meet NRL 8093 Tests 1, 2, and 3, as detailed in Special Material Requirements below. Contractor will coordinate with the VESDA pipe contractor so that the install will be scheduled to coincide with the VESDA pipe install.

Contractor will remove existing absorber according to the VESDA pipe path provided by VESDA pipe contractor in advance of the VESDA pipe install. Contractor will provide disposal of existing absorber. Contractor must provide all supplies necessary to permanently attach RF absorber to ceiling.

Special Requirements:

See attachment “absorber_diagram.pdf” for ceiling absorber layout to be replaced.
