What is EN ISO 22835:2012?

EN ISO 22835:2012 is a professional technical standard that specifies the requirements for the design, fabrication, and inspection of pressure vessels made from composite materials, such as fiberglass-reinforced plastics (FRP). This standard provides guidelines and regulations to ensure the safety and reliability of composite pressure vessels used in various industries.

The Importance of EN ISO 22835:2012

EN ISO 22835:2012 plays a crucial role in safeguarding the integrity and performance of composite pressure vessels. These vessels are extensively used in industries like chemical processing, oil and gas, water treatment, and aerospace. Adhering to this standard ensures that these vessels meet specific quality standards, have adequate strength and durability, and can withstand the intended operating conditions.

Key Requirements of EN ISO 22835:2012

This standard outlines several key requirements that need to be met during the design, fabrication, and inspection of composite pressure vessels. Some of these requirements include:

Material selection: The standard specifies the types of composite materials suitable for pressure vessel construction and their properties.

Design considerations: EN ISO 22835:2012 provides guidelines for designing pressure vessels with appropriate dimensions, wall thickness, and reinforcement to ensure structural integrity and safety.

Fabrication processes: The standard covers the manufacturing processes, such as filament winding, hand lay-up, and autoclave curing, to ensure consistent and reliable production of pressure vessels.

Testing and inspection: EN ISO 22835:2012 establishes procedures for testing samples of composite pressure vessels to verify their mechanical properties, such as burst pressure and fatigue resistance. It also outlines inspection methods to detect any defects or imperfections.

Benefits of Complying with EN ISO 22835:2012

Compliance with EN ISO 22835:2012 offers several advantages, including:

Safety assurance: Following this standard ensures that composite pressure vessels are designed and manufactured to meet specific safety requirements, minimizing the risk of accidents or failures.

Quality assurance: Adhering to EN ISO 22835:2012 guarantees that pressure vessels are produced with consistent quality, meeting predefined standards for performance and durability.

Market acceptance: Many industries require compliance with international technical standards like EN ISO 22835:2012, so adherence to this standard helps manufacturers gain credibility, expand their market reach, and increase customer confidence.
