17 Comments from Voters Member: Comment: Date: Austria (ON) Comment :17:05 OENORM EN ISO Brazil (ABNT) Comment :48:58 As this document may cover changes related to API-14A, adopted by the referred letter ballot, as well as editorial changes from supplement, and as the hydraulic control circuits for SCSSV have many standard work pressures from 34.5 to MPa (from 5,000 to 15,000 psi) involving several manufacturer written calibration specifications, which are specific to the well parameters, we suggest the supplier/manufacturer providing the SCSSV calculation routine to calibrate all part number and serial number SCSSVs with nitrogen chamber. This could be done adding a supplement in the section 7.9, ISO 10432, third edition Due to the production demand, the necessary time to calibrate nitrogen chamber SCSSVs could be abbreviated if the calculation routine could be performed by the operator technical staff, instead waiting data from the supplier/manufacturer. China (SAC) Comment :50:28 It is intended to be adopted in the future.

18 Comment :27:40 BS EN ISO 10432:2004 Comment :24:25 The MMS elected not to adopt the 11 th edition of API Spec 14A in a final rule issued 3/15/2007 even though they were involved in and aware of the changes to the 11 th edition from the 10 th edition (which they have adopted). Believing that this time they will participate again and provide the taskgroup with language acceptable to them and subsequently adopt the results into legislation, the US suggests we vote to revise/amend the document. Adopted as API Spec 14A, 11th edition Products in this country are based on API Spec 14A which is an identical adoption of ISO 10432Referenced in US Code of Federal Regulations 30CFR and 30CFR
