	Normally PVC pipes have been specified in kgf per square centimeter & in PN as units for example '2.5 kgf per square centimeter & P.N. 2.5'. What is the difference between these units. How these units describe the quality, characteristics of the pipe? Regards, Pradip

	They don't. One is a unit of pressure and one is a unit fo force. Kilogram-force per square centimetre - Wikipedia, the free ... Newton (unit) - Wikipedia, the free encyclopedia

	About 3.5%, if PN is interpreted as bar. __________________ In vino veritas; in cervisia carmen; in aqua E. coli.

	... though temperature has not been mentioned. One wouldn't expect PVC pipe to survive superheated steam at any temperature or pressure, for example. So #1↑ is applicable. __________________ "Did you get my e-mail?" - "The biggest problem in communication is the illusion that it has taken place" - George Bernard Shaw, 1856
