RE: Cartoned Group A Plastics

When needing definitions, Chap 3 of the 2016 is where you want to start. 3.9.1.1 gives your definition of Cartoned. Travis Mack, CFPS, CWBSP, RME-G, SET MFP Design, LLC 3356 E Vallejo Ct Gilbert, AZ 85298 480-505-9271 fax: 866-430-6107

RE: [EXTERNAL] RE: Antifreeze temperature requirements

Yes. It is just a mean temperature to use. Are we to use the 100 yr lowest recorded temp? 50 yr? Just lowest in recorded history? Maybe Ice Age temps?  Travis Mack, CFPS, CWBSP, RME-G, SET MFP Design, LLC 3356 E Vallejo Ct Gilbert, AZ 85298 480-505-9271

RE: [EXTERNAL] RE: Antifreeze temperature requirements

Chap 10 in NFPA 13 2016 has the isothermal lines. Long ago, I was directed by one of the national organizations to use this map for determining temperatures for freeze protection. Travis Mack, CFPS, CWBSP, RME-G, SET MFP Design, LLC 3356 E Vallejo Ct

RE: OS "flow rates"

LMAO!!! You can't make this stuff up. Give him the equivalent foot in 13. Figure out the loss for your flow then give it showing equal. 4 ft' of valve A = 4' of valve B. Travis Mack, CFPS, CWBSP, RME-G, SET MFP Design, LLC 3356 E Vallejo Ct Gilbert, AZ

RE: OS "flow rates"

I've given up trying to figure people out. Some just can't be bothered. There is an equivalent foot chart in NFPA 13 for gate valves. You could give him that for reference. If he is still adamant to see a graph, you could make quick spreadsheet to calculate pressure losses based on

RE: When to Measuring Along the Slope

this case it is 2/12. Bobby Gillett Seago Fire Protection, LLC 850-217-3899 cell 850-836-2288 office 850-836-2277 fax _ From: Sprinklerforum mailto:sprinklerforum-boun...@lists.firesprinkler.org> > on behalf of Travis Mack, SET, CFPS, CWBSP, RME-G mailto

RE: When to Measuring Along the Slope

My conservative opinion is no. You calc on the flat, but space on the slope. So, if your dimension along that slope is 15'-1", then you have exceeded the limits without shifting the sprinkler for small room rule. Travis Mack, CFPS, CWBSP, RME-G, SET MFP

RE: Boat Storage

Send it to an FPE for a performance based design. There will not be prescriptive standards to address that situation. Travis Mack, CFPS, CWBSP, RME-G, SET MFP Design, LLC 3356 E Vallejo Ct Gilbert, AZ 85298 480-505-9271 fax: 866-430-6107

RE: Boat Storage

Nothing in NFPA standards for it. Check with the insurance company for the project. They may have guidance. Travis Mack, CFPS, CWBSP, RME-G, SET MFP Design, LLC 3356 E Vallejo Ct Gilbert, AZ 85298 480-505-9271 fax: 866-430-6107

up during a replacement. However, 11.2k ex cov and 5.6k std cov have different thread sizes, so I think it would be quite challenging to get the sprinklers mixed up if you have to replace one. Travis Mack, SET MFP Design, LLC 3356 E Vallejo Ct Gilbert, AZ 85298 480-505-
