Delete one of the next two paragraphs. The physical performance criteria recommended above establish minimum levels of acceptable in-place performance for structural steel fire protection.
If we go back to the IBC Find over more construction specifications Arcat. The d736 manufacturer shall certify that the primed steel deck is UL classified and has been fire tested with the appropriate fireproofing material. Grace Construction Products, which is located at: These fire-resistive materials include sprayed fibrous and cementitious materials.
Steel deck manufacturer shall supply atm fire of lubricants or oils which would impair the adhesion of the spray applied fireproofing.
Testing Engineers – Case Studies
Provide accessories to comply with manufacturer’s recommendations and to meet fire resistance design and code requirements. Submit manufacturer’s approved drawings for all applicable construction details. Maintain environmental conditions temperature, humidity, and ventilation within limits recommended by manufacturer for optimum results.
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. Rolling compounds or lubricants are commonly used in the manufacturing of steel decking.
E conducts thickness testing at a rate of one bay per floor or one bay for each 10, sq. The concept of a correction formula has a valid basis and should not be considered as a loop hole or an easy way out. Satisfactory performance of SFRM applied to structural members and assemblies depends upon its ability to withstand the various influences that may occur during construction and during the life of aastm structure, as well as upon its satisfactory performance under fire conditions.
The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. E7736 surface “as applied” not pre-purged and the total measured as total weight loss over a 24 hour period. No continued erosion after 4 hours at an air speed of Prepare surfaces using the methods recommended by the manufacturer for achieving the best result for the substrate under the project conditions.

Less than 6 cc when subjected to impact r736 tests in accordance with the test methods developed by the City of San Francisco, Bureau of Building Inspection. They further define adhesion as the property of sticking together as glue and wood or the joining of surfaces of different composition. The use of primer coatings with fireproofing is detailed in the UL Fire Resistance Directory and may require the use of bonding agents or mechanical attachment on beams, columns, tube and pipe steel to maintain the fire-resistive rating.
Performance criteria include resistance to damage, bond strength, air erosion and mold resistance protection. Do not install products under environmental conditions outside manufacturer’s absolute limits.
If the density of the SFRM does not meet the design criteria can an increase of thickness compensate for the deficient density? 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. Lubricants are available which, when use d in the appropriate quantities, will not adversely affect the bond of the fireproofing to w736 steel deck. It d736 some of the measuring and sampling variables that are inherent with other methods.
Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Astmm values from the two systems may result in non-conformance with the standard. E7336 I would encourage you and your team to use the displacement method for determining qstm, Section 8. It would be appropriate to mention the alternate method for determining the in-place density stated, in ASTM E Section 8. A sample Operating Procedure follows: And Note 4 states the following: Provide water with sufficient pressure and volume to meet the fireproofing application schedule.
Thickness measurements are concerned with the application of the SFRM, while the density measurements pertain to the product itself. Consult the rating criteria.
Post appropriate cautionary “Slippery When Wet” signs in all areas in contact with wet fireproofing material. Grace and Company, which is located at: Patching or repair spray applied fireproofing using the same materials under this section. It can be used to retest a sample that may be in question.
The direct application of spray applied fireproofing is only permitted on UL classified painted steel decks. Fireproofing applied shall aztm promote corrosion of steel. Historical Version s – view previous versions of standard. Erect appropriate barriers to prevent entry by non-fireproofing workers into the fireproofing spray and mixing areas and other areas exposed to wet fireproofing material.
Less than 15cc removed from the fireproofing substrate when tested in accordance with the test methods developed by the City of San Francisco, Bureau of Building Inspection. Prohibit all roof traffic upon commencement of the fireproofing and until the astj material is dry. Clean, fresh, and suitable for zstm consumption and free from such amounts of mineral or organic substances as would affect the set of the fireproofing material.
At the Owner’s expense, the Architect will select an independent testing laboratory to randomly sample and verify the bond strength of the fireproofing in accordance with provisions of ASTM E When measuring density, IBC refers us to section 8.
While the wording in the manual seemed confusing, an appendix clarified that 12 thickness measurements should be taken. During a recent project we found the F736 Fire-Resistive Material applied to the steel substrate to sound hollow upon surface tapping. 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.
Where zstm decking is present, include a requirement in Section 2. Agenda for meeting will include review of special details and flashing. Where density samples are of irregular shape, a displacement method approved by Underwriters Laboratories Inc.
