ISO 11612:2015 Protective clothing – Clothing to protect against heat and flame – Minimum performance requirements
ISO 11612:2015 Protective clothing – Clothing to protect against heat and flame – Minimum performance requirements
ISO 11612:2015 specifies the minimum performance requirements for protective clothing designed to safeguard workers from heat and flame exposure. The standard covers garments such as flame-retardant overalls, jackets, trousers, and specialised heat-resistant clothing used in industries where employees encounter thermal hazards, radiant heat, convective heat, molten metal splash, and brief contact with flame.
Garments certified to ISO 11612 help reduce the risk of burns, serious injury, and heat-related incidents, and support organisational compliance with national and international PPE regulations. To meet the standard, garments must pass a limited flame spread test (Code A) and achieve performance levels in at least one additional heat or molten metal category (Codes B through F). The standard also includes mandatory design requirements covering overlaps, pocket design, fastenings, and construction features to ensure the garment provides consistent and reliable protection.
WHAT IS ISO 11612:2015?
ISO 11612:2015 is an international standard that defines the performance requirements and test methods for protective clothing made from flexible materials intended to protect the wearer (excluding the hands) from heat and flame. The garments may offer protection against one or more types of thermal hazard, including:
- Limited flame spread (Code A)
- Convective heat (Code B)
- Radiant heat (Code C)
- Molten aluminium splash (Code D)
- Molten iron splash (Code E)
- Contact heat (Code F)
These garments play a critical role in occupational health and safety, especially in environments such as metalworking, foundries, welding workshops, petrochemical facilities, utilities, and manufacturing plants where thermal hazards are a daily risk. ISO 11612:2015 ensures that protective clothing consistently performs in real-world conditions and provides clear guidance for selection, testing, and use.
Why does an organisation need ISO 11612:2015?
Organisations in high-risk industries have both a legal and an ethical responsibility to protect workers from thermal hazards. ISO 11612:2015 provides a structured, globally recognised framework for ensuring that PPE used for heat and flame protection meets rigorous and credible performance requirements.
The standard helps organisations to:
- Ensure the safety of employees who face heat, flame, or molten metal exposure.
- Demonstrate compliance with occupational health and safety legislation and PPE regulations.
- Select and approve protective garments that have been tested to recognised international standards.
- Align PPE selection and risk control measures with ISO 45001:2018 Occupational Health and Safety Management System requirements.
- Reduce workplace injuries, prevent fatalities, and minimise potential legal or financial liability related to thermal incidents.
ISO 11612:2015 will assist an organisation with:
- Selecting the correct PPE type and protection level for each thermal hazard.
- Preventing injuries and promoting safe working conditions.
- Meeting regulatory, statutory, and industry compliance requirements.
- Evaluating and testing flame resistant clothing to ensure consistency in performance.
- Providing end-users with clear, standardised information on PPE use, care, and limitations.
What are the benefits of implementing ISO 11612:2015?
Implementing ISO 11612:2015 provides both safety and operational advantages, making it a vital standard for organisations with thermal hazard exposure.
Key benefits include:
- Enhanced worker safety and reduced burn risk
Ensures clothing offers verified protection against flame, heat, and molten metal exposure. - Legal and regulatory compliance
Supports adherence to occupational safety laws, industry regulations, and client requirements. - Improved product credibility and market acceptance
Certified garments carry higher trust and meet international buyer expectations. - Reliable, consistent performance
Ensures PPE continues to perform under demanding conditions with validated safety margins. - Quality assurance and durability
Garments are tested for flame resistance, strength, and retention of protective properties after laundering. - Better operational efficiency
Fewer incidents, reduced downtime, and greater worker confidence enhance overall productivity.
