The alternate option which was previously "Most Stable Orientation" became "Intended Shipping Orientation." Top-Load - On page 16 of 35 in the Before You Begin Vibration Testing section, the top-load maximum weight of 600lbs was eliminated. Shock - Clarification to the wording within Test Block 16 & 18 was added to ensure that the "largest face" receives the intended impact as face numberings can change based upon orientations determined at the beginning of the procedure - Most Stable or Intended Shipping. Top-Load - Illustrations and enhanced verbiage were added to the Before You Begin Vibration Testing section to clarify how the top-load is to be applied on the test specimen as well as what the top-load is attempting to account for in the real world. Shock - In Test Block 16, on page 33 of 35, the wording for Package Type was amended to improve consistency across ISTA test procedures & projects (from Standard to Standard-Elongated & from Cylinder to Cylinder-Elongated). The same consistency was applied to Test Block 17. Compression - Machine Apply and Hold as well as Weight and Load Spreader were added as additional options for conducting the compression sequence, Test Block 2. Vibration - A height limitation on stacked vibration was incorporated into Test Block 4 to enhance the procedures ability to correlate to real world scenarios. Title, Scope and Preface were enhanced to reduce confusion on intent of the testing procedure and improve consistency across ISTA test procedures & projects. Enhanced formatting of the "Test Sequence" table, specifically the Sequence #3, to reduce confusion on alternative methods and to improve consistency across ISTA test procedures & projects.
