(b) These Federal manufactured home construction and safety standards seek, to the maximum extent possible, to establish performance requirements. In certain instances, however, the use of specific requirements in the Standard is necessary because, at this time, that is the best available means of identifying the desired performance. The use of specific requirements is not intended to prohibit the utilization of any material, piece of equipment, or system which cannot meet the precise specifications, but which upon evaluation provides equivalent or superior performance. Where any material, piece of equipment, or system which does not meet precise specifications set out in the standard is shown, to the satisfaction of the Secretary, to meet the level of performance of a material, piece of equipment or system which meets the precise specifications, the Secretary may waive the specifications set out in the standard for that material, piece of equipment, or system. Whenever a waiver is issued, the Secretary shall issue an interpretative bulletin which announces the waiver, states that the material, piece of equipment or system meets the required standard of performance, and sets out any limitations or other requirements with respect to how the material, piece of equipment, or system must be used, including any tests of the material, piece of equipment, or system which the Secretary determines must be carried out before it can be used. Where a waiver has been issued, the requirements of the section of the Federal standard to which the waiver relates may be met either by meeting the specifications set out in the standard or by meeting any requirements set out in the interpretative bulletin which announces the waiver.

(c) Interpretative bulletins may also be issued for the following purposes: (1) To clarify the meaning of the standard; and

(2) To assist in the enforcement of the standard.
