If comparable seen progress is not really obtained, the antimicrobial exercise from the product or service hasn't been removed underneath the disorders with the test. Modify the test conditions and repeat the strategy Suitability test.   

In order that excellent steam good quality is preserved, all traps, separators, and coalescing products have to be inspected periodically. Steam traps are Particularly prone to complications. Suitable operating is usually evaluated by measuring and recording the temperature and tension drop across Just about every trap or by infrared examination with the steam lines.
