STANAG 4515
Defence explosives test laboratories and manufacturers working to a contract or national programme that invokes STANAG 4515
STANAG 4515 is NATO's agreement setting the common test method nations use to characterise the thermal behaviour of explosive materials by DTA, DSC, HFC and TGA.
STANAG 4515 is the NATO Standardization Agreement that sets out a common method for characterising the thermal behaviour of explosive materials. The techniques it covers are differential thermal analysis (DTA), differential scanning calorimetry (DSC), heat flow calorimetry (HFC) and thermogravimetric analysis (TGA): established laboratory methods used to see how an explosive material behaves as its temperature changes. This is Edition 2, promulgated 11 December 2015; the document does not describe what changed from the edition it replaced.
A STANAG is usually the agreement by which NATO nations commit to a common approach, with the technical substance living in a separate Allied Publication it points to. This one is unusual: Participating Nations "agree to adopt the test procedures described in Annex B for the characterization of explosives using thermal analytical techniques and to use the data sheet at Annex D for reporting test results," and the substance sits directly in this STANAG's own annexes rather than in a document it merely covers.
Thermal characterisation data feeds decisions made elsewhere: whether an explosive is chemically compatible with the materials it will sit against, whether a propellant meets a stability limit, and the kind of comparative data weighed when a material is assessed for a military role. None of those decisions holds up if the data behind it was produced by a method that varies between laboratories. STANAG 4515 exists so that a thermal curve produced in one nation's laboratory means the same thing when it is read in another's.
The test procedures are addressed to the people who run them. Annex A's general considerations are explicit that "safety of the operator is of primary importance" in planning this kind of work. What a test run produces is a record on NATO's own data sheet at Annex D: the laboratory, the technique and specimen, and where the data was sent, alongside a result summary and the thermal curve itself - a documented, reproducible reading of the material's behaviour, not a verdict on whether it is safe or approved for a role. The STANAG is explicit about that boundary: it "refers only to technical suitability and in no way absolves the user from the statutory obligations relating to health and safety at any stage during use." The testing establishes technical facts about the material; the separate legal duties around handling it stay exactly where they already sat.
This agreement binds a NATO nation once ratified and recorded in the NATO Standardization Document Database. Implementation is a further step: the STANAG is treated as implemented once "that nation has issued instructions that thermal characterization of explosives shall be performed by the test procedures described in this STANAG." For a laboratory or a supplier, it arrives through whatever national procurement route, contract or tender invokes that instruction, not because the STANAG exists on its own.
The work STANAG 4515 describes is laboratory science: running an instrument, weighing a sample, reading a thermal curve. ComplyTrain does not perform that testing, and it does not generate, interpret or hold thermal analysis results on a company's behalf.
What it supports is the paperwork around that work: holding each technique's procedure under document control so a laboratory runs the version that was actually agreed, rather than one an individual operator has quietly adapted; keeping training records for the operators who run the equipment, given the STANAG's own safety framing puts that responsibility on them personally; and recording the internal review that confirms a completed Annex D data sheet was checked before it left the laboratory. Where this data feeds a larger submission - a compatibility file under STANAG 4147, a stability assessment under STANAG 4582, or a qualification package elsewhere - ComplyTrain also holds the evidence trail connecting the two, so it is not reassembled from memory later.
ComplyTrain does not characterise, test or handle explosive material, does not generate thermal analysis data, and cannot certify or approve a result on a company's behalf. Which explosives and ammunition standards actually apply to a given testing programme, and at what tier, is set by the contract and the customer's quality clause.

Only where a nation has ratified and implemented it, and it reaches a supplier or a laboratory only where a contract or a national testing programme invokes it. The STANAG binds nations, not companies directly; a laboratory follows it because a customer or a national instruction requires it.
No. STANAG 4515 names no certification, qualification or approval scheme at all, for a company or otherwise. It sets a test method; any decision about whether an explosive is safe, compatible or approved for a role is made under a different document, using data this method produced.
STANAG 4515 sets the general thermal analysis method. The related STANAGs use that kind of data for a specific purpose: STANAG 4147 for chemical compatibility between an explosive and the materials around it, and STANAG 4582 for stability limits specific to nitrocellulose-based propellants measured by heat flow calorimetry. STANAG 4515 is the common method that feeds data into each of those.
It carries safety framing for planning the testing itself, but it is explicit that this "refers only to technical suitability and in no way absolves the user from the statutory obligations relating to health and safety at any stage during use." Those statutory obligations, not this STANAG, govern explosives handling and safety generally.
A completed report, on NATO's own Annex D data sheet, records which technique was used, details of the specimen, and where the data was sent, alongside a result summary and the thermal curve itself. It documents how the material behaved under the test, not a judgement on whether it is safe, qualified or suitable for use.
One system for the whole compliance programme. Start with the module you need most.
Collect information the same way every time, and decide in advance what happens next.
Know whether your controls are operating, not just whether a policy says they exist.
Turn the compliance work you already know about into a plan with owners, dependencies and dates.
Know what you can offer, and hold the evidence behind every configuration you offer it in.
