What is ISO 17636?

ISO 17636 consists of two parts:

  1. ISO 17636-1:2022 – Radiographic Testing using Film Techniques
  2. ISO 17636-2:2022 – Radiographic Testing using Digital Detectors

These standards specify the technique, equipment, exposure conditions, image quality indicators (IQI), and acceptance criteria for radiographic testing of welds in steel, aluminum, and other metallic materials. It is widely used in industries such as oil & gas, aerospace, shipbuilding, pipelines, power plants, and heavy engineering.

Radiographic testing (RT) is a critical method in non-destructive testing to detect internal defects like cracks, porosity, or inclusions that may compromise safety and functionality.

Why is ISO 17636 important?

Implementing ISO 17636:2022 ensures that your radiographic testing methods comply with international quality and safety benchmarks. This is crucial for industries where weld integrity is non-negotiable. Whether you are a fabricator, EPC contractor, or asset owner, this standard helps verify that your welds meet the required strength and durability specifications.

By opting for ISO 17636:2022, your organization showcases its commitment to quality control, safety, regulatory compliance, and risk mitigation, strengthening both domestic and international credibility

What are the benefits of ISO 17636?

  1. Enhanced Detection Accuracy: Enables precise identification of internal weld flaws using either film or digital RT techniques.
  2. Standardized Testing Approach: Ensures consistent radiographic testing procedures across locations and teams.
  3. Regulatory Compliance: Aligns with global codes and standards such as ASME, AWS, EN, and IAEA requirements.
  4. Quality Assurance: Demonstrates a strong quality control system for welded structures and components.
  5. Documentation Support: Standardizes the recording, storage, and traceability of radiographic inspection records.
  6. Auditor & Inspector Readiness: Prepares your system for third-party inspections and customer audits.

What kind of businesses can benefit from ISO 17636?

Implementing and getting certified to ISO 17636:2022 can significantly strengthen your organization's operations. Key business benefits include:

Improved Safety and Reliability: Accurate detection of weld defects helps prevent structural failures and safety risks.

Global Market Access: Certification opens up opportunities to participate in international tenders and projects requiring ISO 17636 compliance.

Customer Confidence: Clients trust businesses that follow internationally recognized NDT procedures.

Reduced Rework & Waste: Early defect identification lowers repair costs, material waste, and delays.

Competitive Edge: Stay ahead in highly regulated industries by offering certified welding inspection capabilities.

Efficient Audit Readiness: Structured documentation and procedures simplify internal and external audits.
