These test procedures were developed based upon the knowledge that steel panel dent resistance characteristics are strain rate dependent. The “quasi-static” section of the procedure simulates real world dent phenomena that occur at low indenter velocities such as palm-printing, elbow marks, plant handling, etc. The indenter velocity specified in this section of the procedure is set to minimize material strain rate effects. The dynamic section of the procedure simulates loading conditions that occur at higher indenter velocities, such as hail impact, shopping carts, and door-to-door parking lot impact. Three dent test schedules are addressed in this procedure. Schedule A is for use with a specified laboratory prepared (generic) panel, Schedule B is for use with a formed automotive outer body panel or assembly, and Schedule C addresses end product or full vehicle testing.

This SAE Recommended Practice provides an orderly series for designating the thickness of unocated and coated hot-rolled and cold-rolled sheet and strip. This document also provides methods for specifying thickness tolerances.

This SAE Recommended Practice describes a method for measuring Roughness Average (Ra) and Peak Count (PC) of the surface of cold-rolled steel sheet.

This method is recommended for establishing breakage allowances for parts fabricated from cut lengths or blanks, or from coils processed directly into a progressive-die pressline, and is equitable to both the sheet producer and the fabricator.

This SAE Recommended Practice describes methods for determining plastic deformation encountered in the forming or drawing of sheet steel.

This SAE Recommended Practice outlines a procedure for selecting the proper specification for carbon steel sheet and strip which are purchased to make an identified part. Specifications considered are: It also describes how codes or symbols for specifying certain characteristics may be used in electronic data processing systems. Characteristics covered are: a Hot or cold rolled. b Sheet or strip. c Severity of draw (quality of steel). d Surface condition (finish, etc.). e Edge condition. f Dimensions. It is intended that other characteristics and part identification be covered by a supplement to the specification, as necessary.

The preferred thicknesses in Table 1 provide an orderly metric (SI) series for designating the thickness of uncoated flat metal products of rectangular cross section. The thicknesses shown are also applicable to base metals which may be coated in later operations.
