ISO 15848-1 Selection of Temperature Class and target temperature
ISO 15848-1 Selection of Temperature Class and target temperature
(OP)
With respect to ISO 15848-1
is temperature class = Design temperature?
Should the target temperature be the design temperature of the valve? If so where is it specified or where will it be specified?
Is there any ISO standard or BS EN standard or code (not the client specification) that refers to ISO 15848?

If API 6A, the data sheet will show you the temp classs and this is given in alphabet such as "K", "L" etc K signifies -60, L signifies -46 and so on.

We have B16.34, API 6D, ISO 17292 valves in our project.

For example, if you have a valve with a design temperature range to API class P+U (-29C to +121C), then you would have to qualify the valve ISO 15848-1 temperature classes t200C and t-46C (meaning you have to test the high end at 200C or higher and the low end at -46C or lower).
RE: ISO 15848-1 Selection of Temperature Class and target temperature
Rereading the original inquiry, in answer to the questions:
No, the target temperatures should be those specified by the temperature classes in Table 3 that cover your design temperature (range). This is confirmed by Clause 6.4, which reads:
The mistake I made in my previous post is that I didn't recognize that their class (tRT) actually covers the range -29oC to 40oC.
