9. Hazard Classification Updates
IHC Duration
Compatibility Group
In the past the expiration date for an IHC was one year or less
This was changed to a maximum of two years when deemed reasonable by the IHC authority
(DDESB Memo of 26 Jan 17)
Navy criteria:
Configuration stability
Transport need
Does not delay or take the place of a final hazard classification
(NOSSA ltr of 16 Mar 17)
DoD may assign CG to items in classes 2-9 and not regulated for storage only (predominant hazard)
In the past the CG was assigned based on the explosives within (typically CG S)
This was changed such that the CG is assigned based on the explosives and the other hazardous materials within
(DDESB Memo of 14 Mar 18 - JHC
Minutes)
Statement A: Approved for Release. Distribution is unlimited.

10. Hazard Classification Updates
UN Test 6(d) - DoD
UN Test 6(d) - UN
In the past, the criterion of hazardous effects contained within the package was interpreted that post test there was little or no damage to the package with nothing escaping
This was changed to allow for greater damage to the package (fiberboard packages to be unfurled or opened at the seam) and for the evaluation of whether contents were projected or fell out of an opened package.
(DDESB Memos of 25 Feb 14 and
15 Mar 17)
UN revised the Model Regulations adding the UN Test 6(d) requirement to four additional UN numbers
UN0349 Articles, Explosive, N.O.S.
UN0367 Fuzes, Detonating
UN0384 Components, Explosive Train, N.O.S.
UN0481 Substances, Explosive N.O.S.

STANAG/AOP/SRD concept
Further harmonization with Insensitive Munitions
UN revised the 12 meter drop test application in the Test & Criteria Manual from:
Required for articles containing substances which fail impact, friction, or small scale burning testing
to:
Required for all articles unless waived by the competent authority
(Recommendations on the Transport of Dangerous Goods. Manual of test and Criteria 6th revised edition amendment 1, 2017)
Substance tests alone can not be used to waive the 12 meter drop test requirement for FHC
Statement A: Approved for Release. Distribution is unlimited.

12. Hazard Classification Packaging Connection
Changing an item’s packaging requires the hazard classification to be reevaluated because:
Hazard classifications are assigned based on test results
Tests are conducted on the item in its packaged configuration
Changing the configuration can affect the test results
Reevaluation will consider:
Confinement
Spacing
Quantity per package
Safety devices
Existing test data
