[MW:14761] Fire safe test-API 607

Dear Experts

 

I have a problem with my vendor regarding interpretation of fire safe test of ball valves, according to clause 4.5.2 of API std 607:

 "When a purchase order stipulates fire-tested valves, valves qualified by fire testing as specified in the third or fourth edition of this standard (API Standard 607) may be supplied for a period of 3 years after the date of this standard. After that 3-year period, all certified valves must meet all the requirements of the fourth edition of this standard", 

My interpretation of this clause is fire safe test will be expired after 3- years and manufacture shall repeat the test, but the manufacturer this agree with me and tells me that the certificate will never expired.

Would you please share your technical information with me.

 

Regards,

Himan Nikdin
