Uncharacterised thermal hazards create risk you cannot manage. Get the data to identify, control, and eliminate them.
Reliable thermal hazard data is the starting point for every safe process design, storage decision, and regulatory submission.
Develop a Safe Operating Envelope for Your Materials and Processes
Unidentified thermal hazards in your processes, equipment, and operations create risk you cannot manage. Thermal stability testing gives your teams the data to identify, quantify, and mitigate those hazards before they become incidents.
- Characterise your hazard profile: establish onset temperature, heat of reaction, and pressure behaviour so your teams can identify risks and implement the right controls.
- Set defensible process limits: set operating temperature limits your engineering teams can justify, document, and defend, reducing the risk of over-engineering under regulatory scrutiny.
- Support scale-up decisions: identify and mitigate hazards at each development stage, ensuring your process grows safely without costly redesigns or regulatory hold-ups.
Sigma-HSE gives your engineering, operations, and compliance teams a common, data-driven foundation to identify, understand, and mitigate process risk with confidence.
Refine Your Dryer Parameters and Profiles Without Compromising Safety
Thermal incidents in drying operations stop production, damage equipment, and trigger regulatory intervention. Thermal stability testing gives your process engineers and R&D teams the data to maintain operational continuity and eliminate unplanned shutdowns.
- Establish the true safe temperature ceiling: define the onset of exothermic activity under realistic drying conditions, maintaining safe production while unlocking throughput improvements without costly equipment changes or production trials.
- Validate drying profiles for novel formulations: confirm your proposed temperature profile is safe for the specific material, eliminating the operational uncertainty that leads to batch losses and process interruptions.
- Reduce the risk of incidents and production losses: testing costs a fraction of a single thermal incident, lost batch, or unplanned shutdown, protecting your operations across every production run that follows.
Sigma-HSE gives your process engineers and R&D teams the data to maintain safer, more reliable, and more productive drying operations without compromising safety or continuity.
Ensure Safe Storage, Processing and Transport Controls for Your Hazardous Materials
DSEAR, ATEX, COMAH, and UN transportation regulations place clear obligations on how you store, handle, and ship hazardous materials. Thermal stability testing gives you the accredited data to meet those obligations and demonstrate compliance.
- Meet UN transport and classification requirements: UN regulations require tested SADT data to correctly classify and ship self-reactive substances across borders.
- Define safe storage conditions under DSEAR and ATEX: understand maximum safe storage temperature and time-to-maximum-rate so your operations teams can specify appropriate, compliant controls.
- Strengthen your COMAH safety case: accredited thermal hazard data provides the defensible, third-party validated evidence your COMAH safety report demands, reducing exposure to non-conformity findings and enforcement action.
Sigma-HSE gives your compliance programme the accredited, defensible data it needs to satisfy DSEAR, ATEX, COMAH, and UN transportation and classification requirements across every site and every material.

Frequently asked questions
What is thermal stability testing?
Thermal stability testing characterises how a material behaves when exposed to heat, identifying the temperature at which it begins to decompose, react, or release energy in an uncontrolled way. This data is the foundation of any safe process design involving potentially exothermic materials.
Which thermal stability test is right for my material?
The right test depends on your material type, development stage, and the specific hazard question you need to answer. DSC and Carius Tube are effective early-stage screening tools. ARSST suits reactive mixtures at lab scale. ARC provides the detailed adiabatic data needed for storage, transport, and COMAH compliance. The right starting point is a conversation with one of our experts.
How does Sigma-HSE support us beyond the report?
Every project includes post-project support as standard. Once your report is delivered, our team remains available to help you interpret results, integrate findings into your safety documentation, and translate recommendations into practical next steps, whether that means further testing, consultancy support, or audit preparation.
How quickly can Sigma-HSE turn around thermal stability testing?
Turnaround times depend on the test method and scope of your programme. Contact us with your requirements and deadline and we will confirm feasibility and timelines as part of your bespoke quote.
Can Sigma-HSE support testing across multiple sites or materials?
Yes. Sigma-HSE works with multi-site organisations across the chemical, pharmaceutical, petrochemical, food and beverage, and oil and gas sectors. Whether you need a single screening test or a programme spanning multiple materials and locations, we will scope and deliver a solution that fits your operational and regulatory requirements.
