For every sq. For each finish product specified, two samples, minimum size 6 inches mm square, representing actual product, color, and patterns. When deciding on the extent of the mock-up, consider all the major different types of work on the project.
For example, the work of other trades or air movement in return air plenums can affect the ability of the fireproofing to remain intact on the steel for the life of a building.
Testing Engineers – Case Studies
Mechanical attachment is required on unclassified painted steel decks to maintain the fire-resistive rating. Prior to application of the fireproofing, apply a discontinuous textured spray of Spatterkote SK-3 to the bottom of all flat plate cellular steel floor units and to roof deck assemblies as necessary to meet the fire resistance ratings. Upon request, provide supporting documentation from an independent laboratory attesting to performance results listed in this section.
Where cellular decking is present, include a requirement in Section 2. So, when writing an SOP for performing thickness determination the following could be adopted: Complete placing of concrete on floor and roof decking prior to application of the fireproofing to the underside of steel deck and supporting beams and joists. An on-site mock-up and bond test shall be performed on all unknown or un tested coatings prior to application of fireproofing to determine compatibility.
The physical performance criteria recommended above establish minimum levels of acceptable in-place performance for structural steel fire protection.
When measuring density, IBC refers us to section 8.
The deck manufacturer shall certify that the primed steel deck is UL classified and has been fire tested with the appropriate fireproofing zstm. However, this section does note that 12 thickness measurements are to be taken, and no statement is made regarding adjusting the average of the 12 sstm. The direct application of spray applied fireproofing is only permitted on UL classified painted steel decks. This section is based on the products of W.
Grace and Company, which is located at: Max deformation of 10 percent when subjected to compressive forces of 57 KPa psf. As a laboratory we believe the measurements should be actual not allowables.
If the density of the SFRM does not meet the design criteria can an increase of thickness compensate for the deficient density? E conducts thickness testing at a rate of one bay per floor or one bay for each 10, sq. Prior to application of the fireproofing material over concrete, apply a bonding agent approved by the fireproofing material manufacturer.
Manufacturers proposed for use but not named in these specifications shall submit evidence of ability to meet all requirements specified, and asmt a list of projects of similar design and complexity completed within the past 5 years. With such a conflict we refer to IBC The results of the above tests shall be made awtm to all parties at the completion of pre-designated areas determined during the pre-job conference.

Historical Version s – view previous versions of standard. A firm d736 has at least three 3 years experience in work of the type required by this section. Post appropriate cautionary “Slippery When Wet” signs in all areas in contact with wet fireproofing material. Fireproofing applied shall not promote corrosion of steel.
Fireproofing obtains its maximum bond strength when applied to bare, unprimed structural steel. Lubricants are available which, sstm use d in the appropriate quantities, will not adversely affect the bond of the fireproofing to the steel deck.
Clean, fresh, and suitable for domestic consumption and free from such amounts of mineral or organic substances as would affect the set of the fireproofing material. Such accessories include, but are not limited to, any required or optional items such as Spatterkote SK-3; bonding agents, mechanical attachments; application aids such as metal lath, scrim, or netting; and Monokote Accelerator.

The test method is applicable to both laboratory and field procedures as indicated in Section 7. Agenda for meeting will include review of special details and flashing. The coating supplier should also certify the compatibility of the primer with portland cement based fireproofing.
