Change history

Use the following table to view procedures by year:

Technical: These changes will affect the procedure in the way it is performed, in the levels of the test methods, or the types of test methods used. TECHNICAL changes require the review, discussion and approval of the ISTA Test Series Group (TSG) and ISTA Standards Council.

Editorial: These changes include errors in printing, format, spelling, and punctuation, as well as identified improvements in clarity of interpretation or to reduce or eliminate uncertainty, but may not include any changes that would, in any way, make a technical or substantive change in the Protocol causing re-testing to be necessary. Editorial changes made to text in regards to grammar, typographical errors or human errors in the creation of the document are approved by the ISTA Standards Council Steering Committee.


The following changes have been made in 2024:

  PROCEDURE(S) AFFECTED CHANGE MADE  TYPE OF CHANGE*  DATE OF CHANGE
3LImproved definitions for package types and fragile items to reduce confusion. Editorial  July 2024
3LClarified single parcel size limitation of Length Plus Girth being equal to or less than 165 inches (4.19m).  Length Plus Girth = Length + [(2 x Width) + (2 x Height)] where the length is a packaged-products longest dimension. Editorial  June 2024
6-FedEx-AThrough ISTA’s consensus standards development and maintenance process it was resolved that the 6-FedEx-A test be withdrawn from ISTA’s 6-Series tests.  Using a recent study of package handling within three major small parcel carrier systems in North America, the industry consensus body, and the ISTA Standards Council, determined that the FedEx small parcel delivery system was similar to other major small parcel delivery systems thus making it ineligible for the ISTA 6-Series of tests. Technical   February 2024

 Procedure 3EPer recommendations from the ANSI audit, the American National Standard (ANS) ISTA 3E will reflect English system first with the Metric system second and in parentheses on the temperature chart within page 5.  Additionally, the ANSI standards logo and the words American National Standard are included on the title page of approved American National Standard ISTA 3E.  Editorial    September 2019

The following changes have been made in 2018.


 PROCEDURE(S) AFFECTED CHANGE MADE TYPE OF CHANGE* DATE OF CHANGE
Project 6-Amazon.com - Over BoxingCompressive Vibration - The top load is no longer a required element of the random vibration test block.  The over box is a static variable as the intent of this test is to understand the interactions of the products within the over box. Introducing a variable of box integrity when the product manufacturer does not have control or influence over this variable creates an unnecessary testing element within ISTA 6-Amazon.com-Over Boxing.  Additionally, actual shipment evaluations show limited collapsed over boxes.  

Ensuring adequate exterior package integrity should be the independent element evaluated by Amazon and should not be the burden of the vendor (product manufacturer).  This change will help deliver greater consistency with testing done at various laboratories by reducing false failures when over boxes collapse during testing.  Another benefit to this change would be a significantly improve package testing through put for labs.

Hazard Products - Clarification was added to the materials which could be used to fill the hazard producs.

Identification of Over Box Faces, Edges and Corners -  To deliver greater consistency with the testing, enhancement was made to the identification of the Over Box faces, edges and corners.
TechnicalApril
2018
Project 6-Amazon.com - SIOCNew Package Types - Type G & H were added to address specific handling practices and common challenges experienced by the  product category of TV's & Monitors.  

The wide variation in TV sizes create a packaged-product category which will benefit from having a testing sequence that addresses its specific needs and challenges.  The specific testing sequences will help ensure that all TV‘s are subjected to the same hazards found in the real world and to the hazards which this product type is most susceptible to (i.e. rotational impacts, concentrated impact on the screen, etc).

Unfortunately, due to the wide range of TV packaging sizes and weights, there are instances in which previous testing sequences could have TV‘s tested to two different package types i.e. Flat or Standard even though all TV‘s are susceptible to the same hazards.  For example, a large TV might not qualify as a Flat package type such as the situation of a 75 LED TV which has packaging dimension of (L x W x H) 72.75x12.25x46.125.  Because the smallest dimension is greater than 8, this package is classified andtested as a Standard package.  The Standard package type is not subjected the TV to a concentrated impact or the rotational impacts.

Additionally, there are attributes of TV‘s which are susceptible to hazards such as concentrated impacts to the screen. For example, the labeling of package faces, Standard or Flat, did not specify or call out what package face correlates to the TV screen to ensure that the intended concentrated impact is challenging the screen protection.  Therefore these new package types have a specific package face identification method which will help deliver greater consistency with testing done at various laboratories by reducing inconsistencies with package labeling for this product type.

Clamp Testing - Two changes occurred for Horizontal Compression (clamping simulation):
 1. Inclusion of a non-equivalent alternative for clamp testing using a compression machine.
 2. Two MINIMUM compression force calculations/limitations are incorporated to account for TV‘s being handled as individual items more frequently than other package types.

Compression Test Block Order Changed - The order of testing sequences for vertical compression and clamping were changed to more closely align with packaging flow. Clamping simulation now occurs before vertical compression to account for packages being clamped coming off the truck at receipt prior to being stacked in the fulfillment center (FC) i.e. warehouse.
TechnicalMarch 2018
Procedure 3AA new test block was added for those packaged-products which contain liquids.  The test block is intended to evaluate the closure systems ability to contain the liquid after all other 3A testing elements have been completed i.e. "leak test."  Definition of "liquid" was also included.TechnicalMarch 2018
Procedure 3A1) One (1) sample is still required but an additional statement was added recommending an increased sample size for Fragile items.  Definition of "Fragile" was also included.

2) Additional clarity was given to the "Most Damage Prone Orientation" of drop 16.

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

 PROCEDURE(S) AFFECTED CHANGE MADE TYPE OF CHANGE* DATE OF CHANGE
 Procedure 3ECompression - 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.
 Technical    April 2017
 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. Editorial 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 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.
 Technical    March 2017
 Procedure 3BTop-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 3FCompression - 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.

  PROCEDURE(S) AFFECTED  CHANGE MADE  TYPE OF CHANGE*  DATE OF CHANGE
 Project 6-Amazon.com - SIOCClamp Testing - Greater clarity on which faces should have clamp testing conducted. Previous TEST Block indicated that two axes needed clamp testing and this was modified to indicate that Clamp Testing is only required when that dimension, either Length and/or Width, is within the given parameters.

Previous Statement on Clamp Testing: 
Horizontal compression (clamping simulation) tests are only required in certain situations as follows: 
1. Clamp testing is required in two axes where the dimension is 24 in (610 mm) or greater and less than 75 in (1905 mm)
2. No clamping tests are required for Type A and Type F.

New Statement on Clamp Testing: 
Horizontal compression (clamping simulation) tests are only required in certain situations as follows:
1. Clamp testing is required on the Length when the distance between Face 2 and 4 is between 24 in (610 mm) and 75 in (1905 mm). 
2. Clamp testing is required on the Width when the distance between Face 5 and 6 is between 24 in (610 mm) and 75 in (1905 mm). 
3. No clamping tests are required for Type A and Type F.

Leak Testing - TEST Block 25 was added to challenge the seal integrity of test specimens that contain liquids. 
Technical  May 2016
Project 6-Amazon.com - SIOCMinor editorial changes occurred to improve consistency across ISTA test procedures & projects. Editorial May 2016
Project 6-AMAZON.com-BThe original test was developed specifically to address Heavy & Bulky packaged-products greater than 70lbs. Since then the goal was amended to include all packaged-products that Ships-In-Own-Container (SIOC) from an Amazon.com fulliment center. For this reason, the title was changed from "Project 6-Amazon.com-B, Heavy/Bulky Packaged-Products for Amazon.com Distribution System Shipment" to "Project 6-Amazon.com, Ships in Own Container (SIOC) for Amazon.com Distribution System Shipment." Additionally the scope and preface were updated to provide greater clarity of the tests intent. Editorial March 2016
Project 6-AMAZON.com-B Due to the scope of the test being increased from Heavy/Bulky packaged-products over 70lbs to any packaged-product that will not be over packed by Amazon a.k.a. Ships in Own Container (SIOC), several elements of the protocol were changed. The test type selection criteria was redefined to align with the new SIOC protocol scope change. Other changes included ...
* Normalizing the hazard sequences to drive consistency across the different packaged-product test types and more closely align with the Amazon supply chain 
* Clamp Testing was changed from "Optional" to "Required" for five of the six packaged-product test types
* Clamp Testing method was modified from clamp and hold to a clamp, lift 12 inches & then hold. 
* Rotational Drops were standardized to 9" from varying heights based upon weight and test sequence 
* Maximum compression requirements was reduced from 7,500lbs to 5,000lbs
* Tip Over Testing is required on all four sides
* Vibration duration was moved from distance traveled to a set duration of 80 minutes per side.

Procedure 3BIn 2013 the ISTA Testing Council voted to move Project 3B to procedure status. When this change was made the version date of 3B was erroneously changed to 2013. This change should not have been made because a project moving to procedure status is not considered to be a change that's technical in nature. After review and vote from the Technical Steering Committee the version date of 3B has been changed back to 2012, the year of its most recent technical change.EditorialJanuary 2016

ISTA RELEASES PROJECT 6-SAMSCLUB; PROJECT 3J DISCONTINUED FOR 2011

ISTA released Project 6-SAMSCLUB in 2010 (Packaged-Products for Sam's Club® Distribution System Shipment). Project 3J has been discontinued for 2011.

6-SAMSCLUB covers 4 main types of shipments received by Sam‘s Club:

  • Type A: Non-Perishable, initially shipped palletized (on standard or custom pallet)
  • Type B: Non-Perishable, initially shipped floor-loaded, defined as Large
  • Type C: Non-Perishable, initially shipped floor-loaded, defined as Small
  • Type D: Perishable

Sam‘s Club Suppliers and ISTA Certified Testing Labs are encouraged to use 6-SAMSCLUB in lieu of Project 3J. ISTA Members may download the full project, and test report form templates, through their ISTA Member Center account. Non-members can purchase the full project through the E-Market

ISTA® 6-SAMSCLUB is essentially an enhancement of ISTA® Project 3J, which was released early in 2010. After initial release of 3J, several requests for changes were made, prompting ISTA Staff to work with the packaging department at Sam‘s Club to revise and re-classify this test project within our 6-Series (Member Performance Tests). 6-SAMSCLUB is more focused on the specific environment of the Sam‘s Club store and less on generic club store distribution systems.

Project 3J will not be published in 2011. ISTA will be revising this project to make it more general for club store distribution. A re-release date of late 2011 or early 2012 is expected. All Sam‘s Club suppliers should now use 6-SAMSCLUB.

The following changes have been made to ISTA Procedures since the release of the 2008 Resource Book. Members may LOGIN to download the most current versions of ISTA Procedures.

 PROCEDURE(S) AFFECTED CHANGE MADETYPE OF CHANGE*  DATE OF CHANGE
 2BTest Sequence (page 3 of 15), Corrected Step 5 to show proper levels, added Rotational Edge Drop as Step 6, updated "Note" after table to show vibration sequences as #4 and #7

Corrected value used in formula for Fixed Displacement Vibration (page 8 of 15). Value should be 11,800 vibratory impacts.

A note was added to the Before You Begin Compression section to clarify that when the S-value is 1 (or when the user knows nothing will be stacked on the unit), the formula will equal zero and therefore no compression is necessary.
