Table 1.6.1.3 Conversion Factors Name of Unit Unit Symbol Conversion Factor liter L 1 gal = 3.785 L 1 gpm/ft 2 = 40.746 mm/min = millimeter per minute mm/min 40.746 (L/min)/m 2 cubic decimeter dm 3 1 gal = 3.785 dm 3 pascal Pa 1 psi = 6894.757 Pa bar bar 1 psi = 0.0689 bar bar bar 1 bar = 10 5 Pa Note: For additional conversions and information, see ASTM SI 10, Standard for Use of the International System of Units (SI): The Modern Metric System. 1.6.1.4 If a value for measurement as given in this standard is followed by an equivalent value in other units, the first stated shall be regarded as the requirement.
0 of 579 5/19/2014 1:50 PM 1.6.2 Hydraulic Symbols. The standard abbreviations in Table 1.6.2 shall be used on the hydraulic calculation form discussed in Chapter 23.

This can be a plus value or a minus value. If minus, the (-) shall be used; if plus, no sign is needed.

The 2016 edition is moving to a soft conversion approach for metric conversions. The "metric conversion task group" must look at section 1.6 and provide guidance to the users on the conversion rules and how the conversions are being made. The metric conversion task group must review the entire first draft and provide the metric conversion for each of the values in the standard (including tables and figures). Since soft conversions are being used, the hard conversion table in section 1.6 should be removed so that it does not provide confusion allowing people start mix and match soft and hard conversions. The methodology used for making the conversions should be added to the annex, with examples. Correlating Committee Note No. 1-NFPA 13-2013 [Section No. 1.6]

This definition should not be limited to these spaces. Concealed spaces can be found inside buildings between rooms and between ceilings and floors. They can also be found outside buildings in eaves and overhangs. The space of 1 should not be part of the definition and this language has been discussed by the Cloud Ceiling Task Group.

1 of 579 5/19/2014 1:50 PM Public Comment No. 267-NFPA 13-2014 [ Section No. 3.3.7 ] 3.3.7 Concealed Space. That portion (s) of a building behind walls, over suspended ceilings, in pipe chases and attics, and whose size might normally range from 1 in. (44.45 mm) stud spaces to 8 ft (2.44 m) interstitial truss spaces and that might contain combustible materials such as building structural members, thermal and/or electrical insulation, and ducting. NFPA's Building Code Development Committee (BCDC) suggests to delete the new definition in Section 3.3.7, from FR 76. The definition adds confusion to the AHJ. This standard has worked well without the definition. As the negatie comment by Mr. Meehan points out, the standard already specifies where omissions are allowed. The definition as proposed introduces a laundry list that is limiting. The definition also introduces dimensions that are limiting. Ultimately, this is less useful to the AHJ in applying the omissions in Section 8.15.1.2. Section 3.1 indicates that terms not defined shall use their ordinarily accepted meaning, which suffices. Note that NFPA 96 only uses the term concealed spaces once, and its application is for lighting units on commercial cooking hoods. This is a very narrow scope for the application of this definition. This definition does not seem to be applicable for sprinkler requirements.

2 of 579 5/19/2014 1:50 PM Public Comment No. 338-NFPA 13-2014 [ Section No. 3.3.7 ] 3.3.7 Concealed Space. That portion (s) of a building behind walls, over suspended ceilings, in pipe chases and attics, and whose size might normally range from 1 in. (44.45 mm) stud spaces to 8 ft (2.44 m) interstitial truss spaces and that might contain combustible materials such as building structural members, thermal and/or electrical insulation, and ducting An area with limited or no access, not intended for building occupant use or storage, that is enclosed on all sides with 4% of the area of one side allowed to be open. There are three concerns with the proposed language: 1) The language is unenforceable. It talks about the fact that the height of the space "might" be in a certain range and that certain things "might" be in the space. We should not be using such language in a definition. 2) The definition is too focused on the space above a drop ceiling and not the hundreds of other concealed spaces in a building such as the vertical spaces within wall stud cavities, crawl spaces, attics, soffits, etc. 3) There is no mention of the space being surrounded in order to be considered "concealed". The space is being defined as "concealed" if it is above a drop ceiling. What about non-continuous drop ceilings? Those spaces would be considered concealed, which is not the intent of the standard. Our proposed definition solves these problems by forcing the space to be surrounded in order to be considered "concealed". The 4% opening limitation comes from the statement in section 8.15.1.2.1.1 that allows "small openings such as those used as return air for a plenum. Such openings tend to be 2 ft x 2 ft in a ceiling grid and tend to occur about every 100 sq ft, which puts them at about 4% of the area of one side of the concealed space.

Where listed pre-engineered systems are installed, they shall be installed within the limitations that have been established by the testing laboratories. Currently NFPA 13D allows pre-engineered systems to be installed as an acceptable alternative. Under the definition of pre-engineered, the systems must have been successfully tested to the appropriate hazard. Allowing alternate systems and new technologies through sections 1.4 and 1.6 of this standard, requires engineering proof that the alternative is equal or better protection than what is in the standard. Often obtaining engineering support or approval can be difficult and expensive. This would open it up to being approved under standard review from an engineer or authority having jurisdiction. I also believe that this is also a correlating issue from 13D.

Additional Proposed Changes File Name LGK_NFPA_13-2013_Comment_6-2-1-1.pdf Description Approved PC Form The idea of removing a sprinkler and thinking that it won't be damaged is a fallacy. There are more ways to damage a sprinkler than by torque. Handling and storage is the critical issue. The need for caps and straps on new sprinklers came from damage during the handling of sprinklers from right out of the manufactures cartons, so it is not possible to assure similar damage won't occur to a dry pendent sprinkler that is removed from its installed location.

It is not practical because no equivalent lengths have been provided for extension fittings.
