What is ISO 7539-9 about?
ISO 7539-9 discusses about Corrosion of metals and alloys. ISO 7539-9 is the ninth part of a multi-series standard. ISO 7539-9 deals with the testing procedures of metals and alloys for determining stress corrosion.
ISO 7539-9 specifies procedures for designing, preparing and using pre-cracked specimens for investigating the susceptibility of metal to stress corrosion cracking (SCC) by means of tests conducted under rising load or rising displacement.
Who is ISO 7539-9 for?
ISO 7539-9 on stress corrosion testing is applicable to:
- Manufacturers of metal and alloy components
- Raw material suppliers to manufacturers
- Test houses/ labs for metal and alloys testing
Why should you use ISO 7539-9?
Stress corrosion testing can determine problematic signs like external and internal corrosion, manufacturing defects, welding and fabrication defects, equipment failures, and incorrect operations. ISO 7539-9 gives you a method for preparing and examining pre-cracked specimens, that allow data to be acquired from critical defect sizes, from which stress corrosion cracking can occur. It helps you estimate the components of known geometry subjected to known stresses. They also enable rates of stress corrosion crack propagation to be determined, which helps you take account of potential impact of dynamic straining on the threshold for stress corrosion cracking.
ISO 7539-9 gives you extensive information on specimen design, stress intensity factor, initiation and propagation of fatigue cracks, environmental consideration, environmental chamber, environmental chamber, environmental control and more allowing you to prevent severe damage to the metals and alloys, as well as your company's reputation.
