ISO 7 R threads 1

[shackney]

Can anyone tell me what an ISO 7 R thread is? I'm thinking that it's just a different name for a BSPT. But I need to be sure.

Thanks in advance.

Steve the dumb question guy.

Steve,

Try looking at the specification(s) you are referring to:

ISO 7-1:1994 Pipe threads where pressure-tight joints are made on the threads -- Part 1: Dimensions, tolerances and designation (

http://www.iso.ch/iso/en/CatalogueDetailPage.CatalogueDetail?CSNUMBER=20819&ICS1=21&ICS2=40&ICS3=30)

ISO 7-2:2000 Pipe threads where pressure-tight joints are made on the threads -- Part 2: Verification by means of limit gauges (

http://www.iso.ch/iso/en/CatalogueDetailPage.CatalogueDetail?CSNUMBER=20820&ICS1=21&ICS2=40&ICS3=30)

Please check the FAQ Where can I get ISO specifications from? (faq182-802)
