ISTA Procedure Changes 2017

Posted in News on 30th August 2017

Are you using the most up-to-date ISTA Procedures and Projects?

A number of notable changes have been made to the ISTA guidelines in 2017.

The two types of changes made are either Technical or Editorial.

Technical changes affect the procedure and must be approved by the ISTA Test Series Group (TSG) as well as the ISTA Technical Division Board and Testing Council, following review and discussion.

Editorial changes include printing and grammatical errors and are used to clarify the text and remove uncertainty without changing the meaning of the procedures in such a way that re-testing would be necessary. They are approved by the ISTA Technical Steering Committee.

The following changes were made to Procedure 3E in April, 2017:

PROCEDURE(S) AFFECTED

CHANGE MADE

TYPE OF CHANGE

DATE OF CHANGE

 

Procedure 3E – Similar Packaged-Products in Utilized Loads for Truckload Shipment

 

Compression – The vehicle and warehouse compression formulas were combined into one enhanced formula which now accounts for a broader range of real world warehouse and vehicle stacking scenarios.

 

Compression – The exception for warehouse compression where if the unitized load was stacked for 48 hours or less then warehouse compression was to be omitted has been removed from the test procedure. All stacking durations are now evaluated.

 

Compression – To more closely replicate real world conditions, a pallet is to be placed on top of the unitized load during the compression testing sequence.

 

Shock – The rotational edge drop height was moved from a fixed height to variable based upon weight. This change references studies and industry test procedures, such as ISTA 3B, which have been conducted since 3E’s inception.

 

Shock – Incline Impact & Horizontal Impact speeds were increased from 42 in per second to 48 in per second. This change references studies and industry test procedures, such as ISTA 3B, which have been conducted since 3E’s inception.

Procedure 3E

 

Title, Scope and Preface were enhanced to reduce confusion on intent of the testing procedure and improve consistency across ISTA test procedures & projects.

April 2017

 

The following changes have been made to the 2017 Resource Book:

PROCEDURE(S) AFFECTED

CHANGE MADE

TYPE OF CHANGE

DATE OF CHANGE

 

Procedure 3B – Packaged-Products for Less-Than-Truckload (LTL) Shipment

 

Orientation – The Identification of Faces, Edges and Corners section on page 12 of 35 was amended to account for the worst case scenario and “Most Stable Orientation” was made the primary means of identifying the faces, edges and corners of the packaged-product. 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.

Procedure 3B

 

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.

 

 

 

 

Editorial

 

 

March 2017

 

Procedure 3F – Packaged-Products in Mixed Pallet Loads for Regional Shipment 100lb (45kg) or less

 

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.

 

 

Technical

 

March 2017

 

Procedure 3F

 

Title, Scope and Preface were enhanced to reduce confusion on intent of the testing procedure and improve consistency across ISTA test procedures & projects.

 

 

Editorial

 

March 2017

 

Procedure 1C – Extended Testing for Packaged-Products 150lb (68kg) or Less

 

 

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.

 

 

Editorial

 

January 2017

 

Project 3K – Fast Moving Consumer Goods to the European Retail Supply Chain

 

 

Corrected typo on test duration in Test Block 9 (Vibration – Random), on page 17 of 20, Step 2. Incorrectly printed as 30 minutes when should have been as 40 minutes.

Procedure 1E – Unitized Loads of Same Product

 

In Test Block 2, on page 7 of 10, Step 1 was corrected to state “Go to TEST BLOCK 3 (Vibration – Random)” rather than Test Block 2 as previously printed.

 

Test Block 2, on page 7 of 8, Step 9 was corrected to state “Go to TEST BLOCK 4 (Shock)” rather than Test Block 3 as previously printed.

 

Test Block 3, on page 7 of 10, Step 5 was corrected to state “Go to TEST BLOCK 4 (Shock)” rather than Test Block 3 as previously printed.

 

Test Block 4, on page 8 of 10, Step 5 was corrected to state “Go to TEST BLOCK 5 (Shock)” rather than Test Block 4 as previously printed.
