If the density of the SFRM does not meet the design criteria can an increase of thickness compensate for the deficient density? Also I would encourage you and your team to use the displacement method for determining density, Section 8. Less than 6 cc when subjected to impact penetration tests in accordance with the test methods developed by the City of San Francisco, Bureau wstm Building Inspection.
The test method is applicable to both laboratory and field procedures as indicated in Section 7.
Monokote MK-6 meets or exceeds these recognized performance standards for long term fire protection of steel structures. With such a conflict we refer to IBC Fireproofing applied shall not promote corrosion of steel. Requests for substitutions will be considered in accordance with provisions of Section However the user should satm cautious as to the extent of the reference.
A firm which has at astn three 3 years experience in work of the type required by this section. Upon request, provide supporting documentation from an independent laboratory attesting to performance satm listed in this section. Referenced Atsm purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Consult the rating criteria. He stated the following: 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.
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. This method measures the volume of the material without the need for thickness or area measurements. Prepare surfaces using the methods recommended by the manufacturer for achieving the best result for the substrate under the project conditions.
Aztm is achieved by prior large-scale fire testing at D736 with the specified fireproofing material. Mechanical attachment is required on unclassified painted steel decks to maintain the fire-resistive rating. With such a significant discrepancy between the two can you explain the right procedure? 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 the structure, as well as upon its satisfactory performance under fire conditions.
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. Is this a contradiction and which frequency should be used? Maintain environmental conditions temperature, humidity, and ventilation within limits recommended by manufacturer for optimum results. Since you suspect an astk application, it would be prudent to test the SFRM qstm the standard method and to also cut around the cap and test just for adhesiveness and report the findings to the design professional.
The following is one example of how a mock-up on a large project might be specified.
Lubricants are available which, when use d in the appropriate quantities, will not adversely affect the bond of the fireproofing to the steel deck. 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. These fire-resistive materials include sprayed fibrous and e376 materials.
The deck manufacturer shall certify that the primed steel astmm is UL classified and has been fire tested with the appropriate fireproofing material. Find over more construction specifications Arcat.
It would be appropriate to mention the alternate method for determining the in-place density stated, in ASTM E Section 8. Patching or repair spray applied fireproofing using the same materials under this section. Provide schedule indicating material to be used, building elements to be protected with spray applied fireproofing, hourly rating and material thickness provided and appropriate references.
Performance criteria include resistance to damage, bond strength, air erosion and mold resistance protection. Prohibit all roof traffic upon commencement of the fireproofing and until the fireproofing material is dry. 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.

For every sq. We recommend the following be added to the structural steel specification: Sample surface “as applied” not pre-purged and the total measured as total weight loss over a 24 hour period. An on-site mock-up and bond test shall be performed e36 all unknown or un tested coatings prior to application of fireproofing to determine compatibility. For SFRM to provide the required level of protection both the minimum average thickness and the density requirements must be r736.
When measuring density, IBC refers us to section 8. Combining values from the two systems may result in non-conformance with the standard.
Cutting around the cap down to the substrate will isolate the bond strength to only adhesion and may there by indicate why your project sounds hollow but would not be a standard method to substantiate an unacceptable application of SRFM.
Do not apply fireproofing until the Architect, applicator and fireproofing testing laboratory’s agent have examined surfaces to receive fireproofing and determined that the surfaces are acceptable to receive the fireproofing material.
Submit manufacturer’s approved drawings for all applicable construction details. Provide water with sufficient pressure and volume to meet the fireproofing application schedule.
Testing Engineers – Case Studies
Where density samples are of irregular shape, a displacement method approved by Underwriters Laboratories Inc. Thickness measurements are concerned with the application of the SFRM, while the density measurements pertain to the product itself. This section is based on the products of W.
