With such a conflict we refer to IBC With such a significant discrepancy between the two can you explain the right procedure? Max deformation of 10 percent when subjected to compressive forces of 57 KPa psf. This section is based on the products of W.
Testing Engineers – Case Studies
On roof decks without a concrete cover, complete all roofing applications and roof mounted equipment installation prior to application of the fireproofing to the underside of roof decking and supporting beams and joists. 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. The direct application of spray applied fireproofing is e73 permitted on UL classified painted steel decks.
Consult the rating criteria.
The concept of a correction formula has a valid basis and should not be considered as a loop hole or an easy way out. Combining values from the two systems may result in non-conformance with the standard. On the other hand, IBC 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 results of the above tests shall be made available to all parties at the completion of pre-designated areas determined during the pre-job conference.
We recommend that Section Metal Decking states: Ducts, piping, equipment or other suspended items are not to be installed until the fireproofing is complete.
Follow the material manufacturer’s application instructions for guidelines on equipment and application procedures. They further define adhesion as the property of sticking together as glue and wood or the joining of surfaces of different composition.
As a worldwide leader in the construction products industry, Grace products are specified by architects and engineers and are used by contractors, ready mix, precast and block producers, cement manufacturers to enhance the durability, strength and appearance of structures found in many major construction projects.
For SFRM to provide the required level of protection both the minimum average thickness and the density requirements must be met.
E36 this question was asked of Luke Woods of W. Since you suspect an improper application, it would be prudent to test the SFRM in the standard method and to also cut around the cap and test just for adhesiveness and report the findings to the design professional.
It would be appropriate to mention the alternate method for determining the in-place density stated, in ASTM E Section 8.
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 asfm necessary to meet the fire resistance ratings.
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 SFRM. We recommend the following be added to the structural steel specification: Delete one of the next two paragraphs.
The following is one example of how a mock-up on a large project might be specified. A firm which has at least three 3 years experience in work of the type required by this section. This would result in an overstatement of the protection level, which must be avoided.
Where cellular decking is present, include a requirement in Section 2. A sample Operating Procedure follows: The test method is applicable to both laboratory and field procedures as indicated in Section 7.
At the Owner’s expense, the Architect will select an independent testing laboratory to randomly sample and verify the bond w736 of the fireproofing in accordance with provisions of ASTM E He stated the following: Classification is achieved by prior large-scale fire testing at UL with the specified fireproofing material. Manufacturers proposed for use e7366 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.
And Note 4 states the following: Monokote MK-6 factory-blended cementitious asmt meeting the following physical performance standards:. Grace Construction Products offers a wide range of innovative specialty construction chemicals and materials that includes: 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.
Is this a contradiction and which frequency should be used?

From a practical viewpoint, the use of actual measurements for density calculations prevents “false high” density calculations. Fireproofing obtains its maximum bond strength when applied to bare, unprimed structural steel. Submit manufacturer’s approved drawings for all applicable construction details.
