Pressure Gauge compliance with EN 837-1 & ASME B40-100

[benny001]

Hi,

Vendor(WIKA) has complied in the bidding stage to supply pressure gauge's design in accordance with EN 837-1 and accuracy in accordance with ASME B40-100. Is it possible to comply the same pressure gauge's design and accuracy with above two different codes?

Regards,

Benji

I'll venture a comment in the absence of any other over 2 months.

It had been decades since I read B40-100 and a good 7-8 years since I flipped through the BS EN 837-1. As I recall, the two standards do not have identical accuracy classes/grades, but I'm sure that Wika, a tier 1 vendor is fully capable of meeting both specs.

I stumbled onto this FAQ statement in a pressure gauge vendor's FAQ, which sheds some light on the differences between the standards. For what it's worth . . .

Q: What is the difference between the ASME B40.1 and EN 837-1 specification? 

A: The American National Standards Institute (ANSI) approves American National Standards which include the American Society of Mechanical Engineers (ASME) standard ASME B40.100. This Standard (B40.100) is confined to analog, dial-type gauges, which, utilizing elastic elements, mechanically sense pressure and indicate it by means of a pointer moving over a graduated scale. The European Committee for Standardization (CEN) is the officially recognized European standards body that develops European Standards (ENs) which include EN 837-1. The EN 837-1 includes mandatory dimensions, metrology, and testing requirement for sale in the European Union. ASME B40.100 includes similar requirements in a non-mandatory appendix.
