Do you feel that Section 1505, IBC 2015, is applicable to requiring a Class B fire classification for a poured playground surface according to ASTM E109 or UL790. This is the top layer of the roof assembly. Is there a case to be made that the “roof covering” requiring the Class B listing is actually the waterproof membrane that sits on the structural deck below the assembly? Might the rubber top layer be considered a “furnishing, playground or equipment,” or some other category which would be exempt from this requirement?
 

Not inside???​

​

424.1 Children's Play Structures​


Children's play structures installed inside all occupancies covered by this code that exceed 10 feet (3048 mm) in height and 150 square feet (14 m2) in area shall comply with Sections 424.2 through 424.5.
 
I am learning new stuff every day. First don't see ASTM E109 as a referenced standard. Next where does it say Class B roof coverings need to be sprinklered if there is a useable space on it?

What code is this from? 10' in height above what (floor, grade, roof, sea level)?

From the great Intergalaxy Building Code

CHAPTER 4 SPECIAL DETAILED REQUIREMENTS BASED ON USE AND OCCUPANCY - 2015 INTERNATIONAL BUILDING CODE (IBC)

ICC Digital Codes is the largest provider of model codes, custom codes and standards used worldwide to construct safe, sustainable, affordable and resilient structures.
codes.iccsafe.org codes.iccsafe.org
 
This is not inside and roof is approximately 60 feet up with protective surround, all of that has been taken care of. Not sure 424 applies since it uses the term "inside" all occupancies.

Most poured product manufacturer's are tested to ASTM D2859, which is a test for textile floor covering materials, and while helpful to know, they do not indicate testing to ASTM E108 or UL790, or give any indication of a Class B roof fire classification, which is what Chapter 15 of North Carolina Building Code requires.

So open air roof

and want to playground up there

What code section do you think requires the deck/ floor to carry a rating?
 
I have attached the NC code sections below.

Should have been ASTM E108, sorry not E109.

Ok what code requires :::::

What code section do you think requires the deck/ floor to carry a rating? JUST because you put a playground up there???
 
I think it is the other way around, not because we put the playground up there. There is a roof rating that is required and we are trying to figure out if the poured playground is part of the roof assembly or considered separate. Section 1505 requires a Class B fire classification. If we place a poured playground surface above the roof assembly as the top layer, does it need to comply with ASTM E109 or UL790? Is there a case to be made that the “roof covering” requiring the Class B listing is actually the waterproof membrane that sits on the structural deck below the assembly? Might the rubber top layer be considered a “furnishing, playground or equipment,” or some other category which would be exempt from this requirement?
 
Ok the real question.

Not my area,

But seems like you meet the required roof rating first.

If you add another layer to that, than unless code or manufacture says NO, than seems like you are good to go.

I guess the other question is what type construction is the building??? And does that limit the type of material that can be put on a roof??
 
[BS] ROOF ASSEMBLY (For application to Chapter 15
only). A system designed to provide weather protection and
resistance to design loads. The system consists of a roof covering
and roof deck or a single component serving as both the
roof covering and the roof deck. A roof assembly includes the
roof deck, vapor retarder, substrate or thermal barrier, insulation,
vapor retarder and roof covering.
[BS] ROOF COVERING. The covering applied to the roof
deck for weather resistance, fire classification or appearance.
ROOF COVERING SYSTEM. See “Roof assembly.”
