Questionnaire on Data Collection in IM/HC tests

Introduction
MSIAC will start two new projects in 2019 that are related to data collection during Insensitive Munition (IM) and Hazard Classification (HC) tests:
  • Guidance on Instrumentation for IM and HC Tests. This project will review the use of existing instrumentation and agreeing and will seek to share and develop best practice.
  • Collation and Analysis of IM and HC Test Data. This project will analyse existing blast, thermal and fragmentation test data to gain a better understanding of the explosive effects for sub-detonative munition responses. The output from this study will be used to inform on reduced consequences from accidents involving IM, which could be taken into account in quantitative risk assessments.
Both projects have been initiated based on recommendations from the 2018 MSIAC Improved Explosives and Munitions Risk Management (IEMRM) workshop. A more detailed description is provided in the Annex at the end of the questionnaire. In 2019, the MSIAC team will receive support from two trainees to conduct these projects. The results will be made available to the MSIAC community in two limited reports.
The projects rely on available information from the IM test centers and other organisations. We therefore kindly ask you to contribute to this questionnaire. Benefits of contributing are that your test procedures and data will be included in the analysis. Also we will make recommendations for improved and harmonized test procedures as well as recommendations for the characterization of the munition responses and their use for safety distances and risk analysis.
 
Timing
Please complete the questionnaire by July 31, 2019.
 
Uploading functionalities are provided at the end of each section of the questionnaire if you wish to share documents (Unclassified unlimited distribution information only​). You can also send an e-mail to Christelle Collet (c.collet@msiac.nato.int) or Martijn van der Voort (m.vandervoort@msiac.nato.int).

Thank you very much! Please provide documentation about your instrumentation and measurement procedure by using the upload area below question 10 or send an e-mail to Christelle Collet (c.collet@msiac.nato.int) or Martijn van der Voort (m.vandervoort@msiac.nato.int). Otherwise, you agree to be contacted later by MSIAC.

Collation and Analysis of IM Test Data
Relevant are IM and HC test reports that describe tests with munition responses “deflagration”, “explosion”, and “partial detonation”. Especially relevant are the IM tests that “failed”, i.e. gave a response that exceeded the permitted IM response according to AOP-39. Also other tests (e.g. done for Hazard Classification purposes or tests conducted at a larger scale) can be highly relevant
Please consider if information from the list below is missing and whether it can be provided separately.
Ideally speaking the following data would be relevant for each test:
  1. Munition
    • Name (please make anonymous if limited distribution)
    • Main Energetic Materials and mass
    • Casing material and mass
    • Casing diameter
    • Casing wall thickness
    • Mitigation measures in place (if any)
    • Design changes made from one to next test (if any)
  2. Type of test
    • Which test is conducted? BI, FI, SR, SH, SCO, FCO or other?
  3. Instrumentation (blast, fragments, thermal, ….)
    • Type of instrumentation
    • Location (distance, angle)
    • Procedure to analyse raw data for data processing
  4. Measurement results (including a confidence interval if available)
    • Measured peak overpressures and positive phase impulses
    • Measured temperatures, thermal fluxes and duration)
    • Measured fragment collection data (mass, distance, pictures of fragment shape)
