BS EN 16602-70-36:2014

What is BS EN 16602-70-36 - Material selection for controlling stress-corrosion cracking about?  

BS EN 16602 is a standard that discusses space product assurance. 

BS EN 16602-70-36 covers the following processes of the general materials, mechanical parts and processes (MMPP) flow of ECSS-Q-ST-70: 

• The selection of metal alloys for which preference is given to approved data sources (Table 5-1 to Table 5-3) 
• The criticality analysis to determine if stress corrosion cracking (SCC) evaluation is necessary 

BS EN 16602-70-36 sets forth the criteria to be used in the selection of materials for spacecraft and associated equipment and facilities so that failure resulting from stress-corrosion is prevented. 

It is intended to provide general criteria to be used in stress-corrosion cracking control, which begins during design thanks to a methodological material selection. 

The criteria established in BS EN 16602-70-36 only apply to designs for service involving exposure conditions similar to testing conditions. 

As regards weldments, BS EN 16602-70-36 applies to aluminium alloys, selected stainless steels in the 300 series and alloys listed in Table 5-1. 

Note 1: BS EN 16602-70-36 does not intend to include all factors and criteria necessary for the total control of stress-corrosion cracking in all alloys. 

Note2:BS EN 16602-70-36 does not apply to listed materials whose behaviour differs at elevated temperatures and in specific chemicals. 

Who is BS EN 16602-70-36 - Material selection for controlling stress-corrosion cracking for? 

BS EN 16602-70-36 on material selection for controlling stress-corrosion cracking is applicable for: 

• Aerospace and defence industry 
• Manufacturers of equipment for aerospace and defence industry 
• Space product manufacturers 
• Quality control personnel
• Design engineers for military aircrafts 

Why should you use BS EN 16602-70-36 - Material selection for controlling stress-corrosion cracking?

Stress corrosion is combined action of sustained tensile stress and corrosion that can lead to the premature failure of materials. 

BS EN 16602-70-36 provides you with the requirements for stress-corrosion cracking. 

Thus, BS EN 16602-70-36 assists you in material selection for controlling stress corrosion cracking. In addition, assists in achieving product quality.
