I have uploaded some pictures of an old Reliable sprinkler, that need to be replaced. They have been sitting in a sky lights. My problem is, that I do'nt know the response time - so I do'nt know which sprinkler type to replace them with. Anybodu that knows the type?

Standard response.
That sprinkler is almost as old as I am.

Check the date on the sprinkler. I don't believe that QR sprinklers came out until mid 90's.
Therefore, it could not have been a QR.

Where?
Temperature rating?
What is the occupancy?
Hazard Classification?
Wet, dry, or pre-action?
Is it a pipe-schedule system?
Orifice diameter?
Ceiling sprinkler rating? (Appears to be a 165F 1/2 orifice sprinkler) but you didn't say
Why does it need to be replaced? It's tarnished from the photos but it looks functional.
It's a standard response sprinkler based on the link design.
The link is thicker than my toe nails (I eat lots of cheese, which makes calcium, which makes toenails).
PS: What will you do if you know the RTI? Model it? That fact you want a response time without using the proper term tells me you are branching into engineering.
PPS: What is Q prime of the design fire?
I am very apprehensive about this post. This sounds like some health care sprinkler post from New Mexico posted last week on another web site. I call this forum shopping.

NFPA 13-2007 Section 8.3.2.5 (4)
Sprinklers under glass or plastic skylights exposed to the direct rays of the sun shall be of the intermediate-temperature classification.
Table 6.2.5.1
Max ceiling temperature of 100°F requires aordinary temp rating of of 135-170 °F
Max ceiling temp of 150°F requires an intermedeiate temp rating of 175-225 °F
Max ceiling temperature of 225°F requires a high temp head of 250=300 °F rating.
Are those heads being replaced because thay are older than 50 yearsor 75 yeears? Or have some been tested and failed the testing?
