Aneed exists to provide a permanent record of the particular environmental test categories that equipment has passed. This need includes post-incident or accident investigation@ installation certification@ repair@ etc. This procedure provides for a paper record (hereafter referred to as the Environmental Qualification Form) to be included in the equipment data package submitted for Technical Standard Order (TSO) authorization and in the installation and maintenance instructions. Since it is not envisioned that the Environmental Qualification Form will be related to a particular equipment by serial number or date of manufacture@ association must be achieved through the equipment type@ model or part number. Manufactures should identify the method used to establish traceability to the environmental test categories to which the equipment was tested@ including the applicable revision number of the test procedure (Section of RTCA/DO-160) used.
