PREPRUFE 300R PLUS - ASTM D543 inquiry

[florisnake]

Hi guys,

We are looking forward to purchase PREPRUFE 300R PLUS waterproof membrane however I have a question.

In the project, under material specification I have a requirement that the waterproof membrane must comply with ASTM D543.
At ASTM D543 requirement for my project I have "Chloride and Sulfate resistance" and the result must be "should show no significant difference".
However, looking at PREPRUFE 300R PLUS data sheet, under ASTM D543 I can see that it retains >80% after immersed in TCE, PCE, BTEX and Acid & Alkaline solution.
Do you guys think that this waterproof membrane qualifies for what I need in the project or should I look for other options? I am a bit confused if retaining >80% after immersed in TCE, PCE, BTEX and Acid & Alkaline solution means the membrane does not qualify with what we need and it means that is indeed shows significant difference to Chloride and Sulfate resistance.

I am sorry if the question seems a bit dumb, I am an engineer at the start of my career and I am trying my best to research & learn as much as possible.
If you guys have an answer, can you please also post a source so I can explain to my boss better?
Thank you guys!

TCE, PCE, BTEX, acid, and alkaline solutions are different parameters from chloride and sulfate resistance. The material's resistance to these compounds doesn't help you at all. Since I don't see any references to chloride or sulfate resitstance in the cut sheet provided, I suggest contacting the manufacturer to obtain this specific information.

I see, thank you very much! I will contact the manufacturer.
