§ 1845.406-70 - NASA policy.

The contracting officer should not authorize contractor use of Government property for independent research and development on a rent-free basis except in unusual circumstances when it has been determined by the contracting officer that—

(a) Such use is clearly in the best interests of the Government (for example, the project can reasonably be expected to be of value in specific Government programs); and

(b) No competitive advantage will accrue to the contractor through such use (see FAR 45.201).
