D10.21 Subcommittee Co‐Chair

AGENDA:

 ASTM History  “The Future of D4169” (2011 Workshop)  ASTM D4169‐16 Revisions  What’s Next?

PRE‐1970

 Prior to 1970, each shipper who did any testing had

their own criteria for a successful package.

 Corporate Test Specifications (GE and Kodak)  National Safe Transit Association (NSTA) has Tests 1

and 1A dating back to 1945.

1970s

 1971 – ISO package testing subcommittee begins

work on package performance standard

 1973 – D10 task group formed to develop package

performance specifications

 1974 – ISO draft proposal circulated; some of its

basic structure adopted by D10 task group

1970s

 1974‐1977 – lots of lively debate…  1977 – US Forest Products Lab (FPL) sponsors

research

 1979 – General Technical Report FPL22 – this report

provides basis for test intensities, etc. in D4169.

 1979 – D10 decides to publish “D4169” concept as

proposal (marketing effort)

1980s

 1981 – After 9 years of development…the 7th draft

• f proposal approved by D10.

 1982 – D4169 published in August.  1984 – D4003 test method added (Schedule H Rail

Switching)

1980s

 1986 – Replaced D685 with D4332 for Conditioning  1988‐1992 – Several revisions published:

• Added DC 15,16, and 17 for import/export
• Added military package testing and DC18
• Added Element J Environmental Hazard
• Revised Element D Vehicle Stacking
• Revised Elements E & G on vibration (D4728 random vibration)

1990s

 1994 – Added criteria for second series of drops in

Element A

 1996 – Added D5277 and D5487 impact test options

for Elements A and H.

 1998 – Changed Elements to Schedules (A thru H);

revised listing of Schedules

 1998 – Added Air PSDs to Schedules D & E

2000s

 2004 – Added Schedule I Low Pressure (High

Altitude) hazard

 2008 – Multiple Revisions:

• Small package express removed from DC3
• Military‐only test requirements moved to A1 Annex
• Schedule H water spray temperatures significantly increased
• Schedule J added

Fall Meeting – 2011

 ASTM Committee D10 Workshop (Tampa)  Presentations given on review of Compression,

Vibration, Rail Switching, and Environmental Hazard Test Elements.

Schedule B, C – Stacking

 Recommended Review Topics:

• Test Level Factors (F)
• Average Shipping Density Factor (10 lb./ft3)
• Note 3 (value of H)

Schedule D, E – Vibration

 Overview of origins of vehicle profiles (FPL22)  Review of other Industry and corporate vibration

profiles

 “Kickoff” for Random Vibration Task Group which

lead to 2016 updates

Schedule G – Rail Switching

 Recommendation to change Schedule G so test

procedures align with Transportation Technology Center approach:

• Four impacts (rotate 180° for fourth impact)
• Two Assurance Levels

Schedule G – Rail Switching

Schedule E – Vehicle Vibration (Truck)

 Distribution environment measurement more cost

effective, common today

 Truck data spectral shape, intensity didn’t correlate

well

 Developments in testing technique improvements

(varied intensity)

Schedule E – Vehicle Vibration (Truck)

 “Revision Awareness” Campaign

• Eric Joneson, Larry Anderson presentations

 ASTM D4169 Truck Profile Update Rationale  Balloted Rationale first to address concerns before

submitting revisions for approval.

Rationale Document

Rationale Document

Rationale Document

 Procedure Guidance added September 2016

• Test Procedure explanation
• PSD Plot Comparisons
• PSD Intensity Comparison

 Added SUMMARY OF CHANGES section

Conditioning (Section 6)

 Proposed revisions to Section 6 (D10.21 (17.03))

• Clarification / addition of recording temperature and

humidity with the time out of conditioning between test schedules

• Addition of F2825 as a reference document
• Addition to Section 18 (Reporting)

Conditioning (Section 6)

 D10.21 Ballot closed September 29

• 3 Negative Votes, 5 Comments
• Technical Contact (Jan Gates) currently working to address

and resolve negatives and comments.

Schedule J – Concentrated Impact

 For certain package types, lab failures do not

correlate well with field results.

 Survey conducted to gather D10 feedback on

Schedule J test procedure.

Schedule J – Concentrated Impact

“Eliminate the test schedule. Remove it from D4169…”

“Move to design testing instead of distribution testing…” “Does Schedule J even correlate to damage seen in the field?”

Schedule J – Concentrated Impact

 Recommended Revisions:

• Recommended test for elongated & flat packages
• Optional design test for all other corrugated shipper sizes
• Optional test for stretch wrapped pallet loads
• Eliminate (275#) exclusion criteria for corrugated fiberboard

Schedule E – Vehicle Vibration

 Rail vibration review

• AAR planning data project (intermodal rail).
• ASTM would like to wait for that data to be available

before further reviewing the rail dynamics.

Rail Vibration review

 Spectral shape, intensity, time  Single axis vs. multi‐axis  Different Rail environments

Rail Vibration review

 Spectral shape, intensity, time  Single axis vs. multi‐axis  Different Rail environments

Schedule E – Vehicle Vibration

 Air vibration review

• What does “Air vibration” include?
• Some data, research available. Need more!

Air Vibration review

Air Vibration review



Spectral shape:

• Do we combine or separate “ground” and “air”?



Intensity / Time:

• Dependent on combining or separating environments



Single or Multi‐axis:

• Aircraft move in 6DOF, ground vehicle move predominantly in

3DOF

Air Vibration review

 Draft Air Vibration Rationale document  Historical data, company data, new data  Goal to have Rationale completed before:

Spring 2018 meetings

Not Too Distant Future…maybe…

 New DCs (E‐commerce)  Combined Environments  Multi‐Axis Vibration  Load Stability
