BS EN 13523-23:2015

What is BS EN 13523-23 – Resistance coil coated metals of humid atmospheres containing sulfur dioxide about ?

BS EN 13523-23 is the 23rd part of the BS EN 13523 multi-series that discusses coil coated metals. 

BS EN 13523-23 defines the terms of the procedure for determining the resistance of an organic coating on a metallic substrate to humid atmospheres containing sulfur dioxide. 

Who is BS EN 13523-23 – Resistance coil coated metals of humid atmospheres containing sulfur dioxide for ?

BS EN 13523-23 on test methods for resistance to humid atmospheres containing sulfur dioxide is useful for: 

• Coil coated metal manufacturing companies 
• Quality control personnel 
• Testing laboratories 

Why should you use BS EN 13523-23 – Resistance coil coated metals of humid atmospheres containing sulfur dioxide ?

Coil coated metals are known for their high resistance to corrosion as compared to other coated metals. However, under certain conditions, the performance of these metals can falter. 

The test method described in BS EN 13523-23 can help you verify the performance of coil coated metals in humid atmospheres containing sulfur dioxide. This can help you identify faults like change in colour, degradations like spotting, streaking and loss of gloss on the surface of coil coated metals.  

Overall, the guidance of BS EN 13523-23 can help you to identify coil coated metals that are best suited for humid atmospheres containing sulfur dioxide.
