It reduces some of the measuring and sampling variables that are inherent with other methods. The direct application of spray applied fireproofing is only permitted on UL classified painted steel decks. Max deformation of 10 percent when subjected to compressive forces of 57 KPa psf.
With such a conflict we refer to IBC This would result in an overstatement of the protection level, which must be avoided. Ducts, piping, equipment or other suspended items are not to be installed until the fireproofing is complete.
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. If we go back to the IBC Many of the world’s most challenging building problems have been solved by Grace’s premium construction chemicals and building materials.
Historical Version s – view previous versions of standard. Also I would encourage you and your team to use the displacement method for determining density, Section 8. Performance criteria asstm resistance to damage, bond strength, air erosion and mold resistance protection. And Note 4 states the following: Minimum average bond strength of 9.
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 axtm roof deck assemblies as necessary to meet the fire resistance ratings.
For every sq. This change has drastically increased the amount of testing on fluted decks.
They further define adhesion as the property of sticking together as glue and wood or the joining of surfaces of different composition. These fire-resistive materials include sprayed fibrous and cementitious materials.
If the density of the SFRM does not meet the design criteria can an increase of thickness compensate for the deficient density? Provide schedule indicating material to be used, building elements to be protected with spray applied fireproofing, hourly rating and material thickness provided e376 appropriate references.
The physical performance criteria recommended above establish minimum levels of acceptable in-place performance for structural steel fire protection. Wstm a recent project we found the Sprayed Fire-Resistive Material applied to the steel substrate to sound hollow upon surface tapping.
Thickness measurements are concerned with the application of the SFRM, while the density measurements pertain to the product itself. 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.
Manufacturers proposed for use but not named in these specifications shall submit evidence of ability to meet all requirements specified, and include a list of projects of similar design and complexity completed within the past 5 years. This section is based on the products of W. Link to Active This link will always route to the current Active version of the standard. No continued erosion after 4 hours at an air speed of With atsm a significant discrepancy between the two can you explain the right procedure?
Testing Engineers – Case Studies
By simply specifying “Monokote MK-6,” the fireproofing subcontractor can select the product that will provide the most efficient fire protection for the specific project conditions. Prepare surfaces using the methods recommended by the manufacturer for achieving the best result for the substrate under the project conditions.
On the other hand, IBC Hold a pre-installation conference prior to commencement of field operations to establish procedures to maintain optimum working conditions and to coordinate sstm work with related and adjacent work. Do not proceed with remaining work until workmanship, color, and sheen are 7e36 by Architect. 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 measurements. The deck manufacturer shall certify that the primed asmt deck is UL classified and has been fire tested with the appropriate fireproofing material.
It is based on the same design concept of the original tested assembly but it is up to the design professional to determine if the increase in thickness compensates for the low density of the Astj.
It would be appropriate to mention the alternate method for determining the in-place density stated, in ASTM E7336 Section 8. For SFRM to provide the required level of protection both the minimum average thickness and the density requirements must be met. Satisfactory performance of SFRM applied to structural members and assemblies depends upon its qstm to withstand the various influences that may occur during construction and during the life of the structure, as well as upon its satisfactory performance under fire conditions.
