ISO 80079-34 Certification

In industries where explosive atmospheres are present, safety is of paramount importance. Various industrial processes, such as petrochemical, mining, pharmaceutical, and food processing, involve the handling of flammable substances, gases, or vapors. To mitigate the risks associated with these hazardous environments, specialized equipment is required. ISO 80079-34 is a crucial international standard that ensures the safety, reliability, and performance of equipment used in explosive atmospheres. In this blog, we will delve into the details of ISO 80079-34, its scope, significance, and requirements.

Understanding ISO 80079-34

ISO 80079-34 is part of the ISO/IEC 80079 series, which deals specifically with explosive atmospheres. This standard, titled “Explosive atmospheres – Part 34: Application of quality management systems for Ex product manufacture,” is designed to address the manufacturing of equipment used in explosive atmospheres, commonly known as Ex equipment. The term “Ex equipment” encompasses a wide range of devices, including electrical, mechanical, and optical equipment.

Scope of ISO 80079-34

The main objective of ISO 80079-34 is to provide manufacturers of Ex equipment with a systematic approach to ensuring that their products comply with the essential safety requirements. The standard outlines the requirements for establishing and implementing a quality management system (QMS) for Ex equipment manufacture. This QMS is critical in assuring the safety and reliability of the equipment used in explosive atmospheres.

The standard encompasses various stages of the manufacturing process, including design, production, assembly, testing, and documentation. It covers all Ex equipment, regardless of the industry or the type of explosive substance it is intended to handle. ISO 80079-34 sets the foundation for quality management principles to be applied throughout the product lifecycle, ensuring consistency and reliability.

Significance of ISO 80079-34

The significance of ISO 80079-34 lies in its ability to enhance safety measures in hazardous environments. By implementing the standard’s guidelines, manufacturers can be confident that their Ex equipment complies with rigorous safety standards, reducing the risk of explosions and accidents. This assurance is not only vital for protecting workers and the environment but also for ensuring business continuity and avoiding costly downtime.

Key Requirements of ISO 80079-34

  1. Quality Management System: Manufacturers must establish and maintain a QMS that aligns with ISO 9001, the internationally recognized standard for general quality management.
  2. Risk Assessment: A comprehensive risk assessment must be conducted to identify potential hazards and assess their potential impact on the Ex equipment.
  3. Documentation: The standard mandates thorough documentation throughout the entire product lifecycle, including design specifications, manufacturing processes, test procedures, and records.
  4. Competency of Personnel: Manufacturers must ensure that their personnel involved in the design, production, and testing of Ex equipment are competent and adequately trained.
  5. Verification and Validation: The standard requires manufacturers to conduct rigorous verification and validation processes to ensure that the Ex equipment meets all specified requirements.
  6. Non-Conformance Management: A system for managing non-conformities and corrective actions must be established to address any deviations from the standard’s requirements.

Benefits of Complying with ISO 80079-34

  1. Enhanced Safety: Compliance with ISO 80079-34 ensures that Ex equipment is designed and manufactured to withstand explosive atmospheres safely, minimizing the risk of accidents and protecting personnel and assets.
  2. Global Market Access: Many countries and industries mandate compliance with ISO 80079-34 for Ex equipment. By adhering to the standard, manufacturers can access a broader market and increase their competitiveness.
  3. Improved Reputation: Companies that comply with the standard demonstrate their commitment to safety and quality, which enhances their reputation among customers and stakeholders.
  4. Risk Mitigation: Rigorous risk assessments and controls implemented as part of the QMS help manufacturers identify potential hazards and mitigate risks effectively.
