Determination of Additives & Stabilizers

Nearly all modern explosives are engineered composite mixtures. Additives control processability, mechanical elasticity, chemical shelf-life, and mandatory detectability.

Plasticizers in Propellants and Explosives

In gun propellants and PBX formulations, energetic plasticizers (such as nitroglycerin, BTTN, or DEGDN) as well as inert phthalates, adipates (DOA), and sebacates (DOS) are employed.

They prevent low-temperature embrittlement and ensure uniform burning rates. We verify concentration, plasticizer migration, and chemical aging stability.

  • Energetic plasticizers (NG, BTTN, TMETN)
  • Inert plasticizers (DOA, DOS, Phthalates)
  • Aging kinetics and stabilizer depletion
Weichmacher Analytik

Detection Agents & Tagging (Montreal Convention)

In compliance with international counter-terrorism standards (ICAO and Montreal Convention), plastic explosives must contain volatile detection marking agents (e.g., DMNB).

These substances generate a distinctive vapor signature detectable by K9 units and IMS vapor detectors. We provide high-precision quantitative gas chromatographic analysis.

  • Quantitative DMNB (2,3-dimethyl-2,3-dinitrobutane) analysis
  • Forensic micro-taggants, optical particles & colorants
  • Batch homogeneity testing in PBX production
Tagging und Duftstoffe

Metal Powders & Reactive Additives

Metallic fuels (aluminum, magnesium, boron, titanium) are added to explosives and propellants to substantially increase blast overpressure, fireball temperature, and total impulse.

We analyze metal content, particle size morphology, surface oxidation layers, and active metal ratios determining ignition kinetics and binder compatibility.

  • Aluminum & magnesium content (AAS / ICP / wet-chemical)
  • Particle size distribution & oxide layer passivization
  • Binder-metal chemical compatibility testing

Sensitivities and Thermal Stabilities

Accurate quantitative assessment of sensitivity to impact, friction, electrostatic discharge, and thermal stimuli is mandatory for UN hazard classification, transport, and safe handling.

Impact Sensitivity according to BAM Standard

The BAM Fall Hammer determines the minimum impact energy in Joules [J] required to initiate detonation, deflagration, or sparking of a defined sample mass.

Testing is indispensable for UN transport classification (Series 3/4) and hazard grouping under ADR, RID, and the Explosives Act.

  • Drop weights ranging from 250 g to 10 kg
  • Statistical evaluation (Bruceton staircase method)
  • Certified test reports according to international standards
BAM Fallhammer Schlagempfindlichkeit

Friction Sensitivity according to BAM

The BAM Friction Apparatus determines the friction force in Newtons [N] exerted between a ceramic peg and porcelain plate that causes reaction or decomposition.

This simulates mechanical shear and friction hazards occurring during mixing, pressing, loading, or mechanical transport in manufacturing.

  • Friction loads from 5 N to 360 N
  • Standardized ceramic friction specimens
  • Dependable safe handling classification
BAM Reibprüfer

Electrostatic Discharge Sensitivity (ESD)

Electrostatic charges on personnel or processing vessels can discharge unpredictably. Our ESD test apparatus determines the minimum ignition energy in millijoules [mJ].

Particularly primary explosives, fine pyrotechnic powders, and igniters require exact threshold testing to design effective grounding and conductive clothing requirements.

  • Capacitive spark discharge (Human Body Model)
  • Ignition energies from sub-millijoules to Joules
  • Investigation of powders, granules, and thin films
ESD Prüfung

Koenen Steel Tube Test

The Koenen test evaluates the thermal response and confinement explosion hazard of an energetic substance subjected to intense heating within a standard steel tube.

Employing orifice plates with nozzle apertures from 1.0 mm to 20.0 mm, the limiting diameter is determined at which rupture or explosion occurs (UN Test Series 1, 2, and 8).

  • Limiting orifice diameter determination for UN transport classification
  • Assessment of explosion hazards under extreme thermal confinement
  • Certified test documentation conforming to UN Manual of Tests
Koenen Stahlhülsentest

Thermal Stability (DSC / DTA / TG)

Differential Scanning Calorimetry (DSC) and Thermogravimetric Analysis (TGA) quantify melting points, glass transitions, onset decomposition temperatures, and reaction enthalpies.

Using kinetic models (Ozawa / Kissinger methods), we calculate activation energies, critical runaway temperatures, and long-term shelf-life predictions.

  • High-pressure sealed crucible and open-pan measurements
  • Exothermic and endothermic phase/decomposition profiling
  • Kinetic shelf-life and thermal stability forecasting

Frequently Asked Questions (FAQ)

Important details regarding sample transport, regulatory licensing, and laboratory turnaround times.

EMTO GmbH holds an official permit according to Section 7 of the German Explosives Act (Sprengstoffgesetz - SprengG) authorizing the handling, testing, and storage of explosive materials. All samples must be declared and pre-registered with proper dangerous goods (ADR/IATA) documentation prior to transport.
For materials that cannot be dispatched via certified dangerous goods couriers, we offer scheduled direct handover or collection by one of our licensed hazardous materials specialists. Please contact us in advance to coordinate packaging specifications.
Thanks to sensitive micro-analytical instruments (HPLC, GC-MS, FTIR), chemical identification typically requires only a few milligrams to grams. For mechanical sensitivity evaluations (BAM Fall Hammer, Friction Tester), 5 to 15 grams of sample are typically requested.
Standard analytical evaluations are usually completed within 5 to 10 business days following sample receipt. In urgent situations (e.g., critical batch release, explosive ordinance identification), an expedited 24- to 48-hour express service is available by arrangement.
