The 2014 edition of NFPA 25 introduces fuel testing requirements in section 8.3.4 with the rather vague description of "testing for degradation" per ASTM D975‐11b. I read a LinkedIn blog referring to this and how different testing companies have different ideas about what should be tested for in...

The firesprinklerorg link is broken and the other just takes me to the NFSA store - where nothing is ever 'free'
NFSA and AFSA have long sold their own versions of the 25 report but you can't buy it as an editable pdf. In this day and age of electronic filing and inspectors using laptops...
"The forms are downloadable from the electronic version of the handbook. I just sent a contractor a Word document I downloaded from the 2013 edition of NFPA 72 which I accessed from my on-line edition"
I'd be interested in knowing how you did that. I have All Access and can view the 25HBK...
Hi Steve
I've sent NFPA an email regarding this. cdafd, every relevant chapter in the Handbook version has an inspection form now. The Handbook is extremely well done for 2014 IMHO.

After reading that first post I am seriously wondering about ever using CPVC again myself - a product I have spoken highly of in the past.

I've had the Handbook pdf on my desktop for a while but have only had a few cursory looks at it. I'm quite impressed with the level of detail they go into now in explaining the proper use of the standard.
I also notice that for the first time in ages they have included actual report forms...
Thx SD2
I haven't seen this one and it will be going into my files. I recall something quite similar posted here though.

In my estimation, if you can tell the orientation you are close enough in most cases to see the temperature rating. This assumes it is a glass bulb or is otherwise indicated on the frame of course.

Hello fireguy
We have the same type of 'disclaimer': This report does not constitute an engineers review, and as such does not formally address installation concerns other than what may be noted under Comments and Recommendations
I'd still like to know why NFPA 25 chose to address orientation...
To clarify, the Hand Book section in regards to the binoculars comment had me rolling my eyes somewhat....

"All of our inspections are done from floor level, no ladder work, how can we see a head to determine its temperature when it is 45' in the air?"
The Hand Book has this fun little ditty : A flashlight or binoculars can assist in the inspection of sprinklers (or
piping) in buildings with high...
LCREP, cdafd,
NFPA 25 seems worse than some religious documents for "interpretations". For the ESFR example, this is dealt with in 4.1.5 and it's explanation in the annex. Similarly regarding design, the inspector may assume that there are sprinklers in the elevator shaft or under the stage in...
Why does chapter 5 not address whether or not a sprinkler head is the correct temperature for its location? They address orientation which assumes it is a sprinkler that has been replaced incorrectly. Why wouldn't this be the same assumption for a high temperature head found in an ordinary...
So. NFPA 25: 4.1.8 Information Sign.
4.1.8.1 A permanently marked metal or rigid plastic information sign shall be placed at the

Hello
I sent this off to NFPA25@nfpa.org:
Hello
I’m trying to understand 13.6.2
13.6.2.1 speaks to the forward flow testing of backflow preventers. A13.6.2.1 starts off by discussing this, then ends with “The tests required by 13.6.2 typically test only for operation of the device under...
For clarity, and yes I jest, item (9) of the same section adds this:
"The system is not required to achieve water delivery to the inspector’s test
connection in 60 seconds, but comparison to the water delivery time during the
original acceptance will determine if there is a problem with the...
NFPA 25 A.13.4.4.2.2.2 (2011 ed)in regards to dry valve test procedures, item (5):
"Testers at the inspector's test note the time at which water flows steadily from the test connection. This time is noted for comparison purposes to previous tests and is not meant to be a specific pass/fail...
Frequently when reading code I'll come across a piece that's hard to digest and I'll decide to ask this good forum for an opinion. Sometimes while writing it down here it will suddenly become clear and I won't have to post it. Other times I will post it and get some valuable information. Here's...
Quoting my friend skdesigner from a closed thread (Pump Affinity Laws August 2012)

I agree but then what do you use the affinity laws for?

Thx my friend. I'm getting old. Rick is working out very well too by the way.
