Flammability Testing for Fire and Ignition Risk

Confirm ignition behaviour, flash point, and fire risk to support safe design, handling, and regulatory compliance.
Flammability testing

Understand your fire and ignition risks with reliable test data

When liquids, powders, or materials are handled, stored, or processed, a lack of reliable flammability data can leave you exposed to fire or explosion risk. Knowing when a material can ignite, at what temperature, and under what conditions is vital for safe design and compliant operations.
Flammability testing provides the defensible, repeatable evidence you need to identify hazards, define safe limits, and make confident decisions.
What flammability testing tells you
  • Flash point testing
    Determines the lowest temperature at which a liquid gives off vapours that can ignite. Essential for processing, storage, and transport.
  • Auto-ignition temperature
    Measures the temperature at which a substance will spontaneously ignite without an external ignition source.
  • Fire retardancy evaluation
    Assesses how materials resist ignition and flame spread under controlled conditions.
  • Supporting fire risk data
    Generate reliable measurements you can use to define safe limits, support DSEAR/ATEX risk assessments, and demonstrate compliance.

Why flammability data matters

Flammability behaviour can change between lab, pilot and plant conditions, which means assumptions can quickly become risky. Reliable data on flash point, auto-ignition and ignition behaviour helps you set safe operating limits, define storage and handling controls, and strengthen fire and explosion risk assessments. It also supports compliance and provides defensible evidence for audits, insurers and regulators, so decisions are based on measured behaviour rather than best guess.

Standards and compliance

Our testing supports compliance, risk assurance, and defensible documentation. We work to industry-accepted methods and can help you interpret results from a regulatory and practical safety perspective.
Whether you need data for:
  • internal risk assessments
  • compliance with UK/EU safety frameworks
  • engineering design decisions
We tailor the output to your needs.
When you might need flammability testing
Flammability testing is appropriate if you are handling or storing flammable liquids or powders, unsure of flash point or auto-ignition behaviour, introducing new chemicals or formulations, preparing risk assessments for DSEAR or ATEX compliance, or incorporating materials into a process where heat or sparks may occur. These tests help refine your Basis of Safety, improve hazard identification, and support defensible engineering decisions.
