Description / Abstract:

INTRODUCTION — Design properties in MMPDS are used in the design of aerospace structures and elements. Thus, it is exceedingly important that the values presented in MMPDS reflect as accurately as possible the actual properties of the products covered.

Throughout the Guidelines, many types of statistical computations are referenced. Since these may not be familiar to all who may be analyzing data in the preparation of MMPDS proposals, a detailed description of each operation is required. To present the detailed description in the individual sections, however, would unnecessarily complicate the orderly presentation of the overall computational procedures. Therefore, the detailed description of the statistical techniques have been covered in Sections 9.5, 9.6, and 9.7.

APPLICABILITY — The minimum data requirements and analytical procedures defined in these Guidelines for establishment of MMPDS design properties and elevated temperature curves should be used to obtain approval of such values or curves when proposed to the MMPDS Coordination Group or a certifying agency. However, the minimum data requirements and analytical procedures are not mandatory; to the extent of precluding use of other analytical procedures which can be substantiated. Any exceptions or deviations must be reported when requesting approval of these values or curves by the Coordination Group or certifying agency.
