On the other hand, IBC Mechanical attachment is required on unclassified painted steel decks to maintain the fire-resistive rating.
Where density samples are of irregular shape, a displacement method approved by Underwriters Laboratories Inc. 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. Clips, hangers, support sleeves and other attachments required to penetrate the fireproofing, must be in place prior to application of the fireproofing materials.
Store and dispose of solvent-based materials, and materials used with solvent-based materials, in accordance with requirements of local authorities having jurisdiction.
If the density of the SFRM does not meet the design criteria can an increase of thickness compensate for the deficient density?
If substrate preparation is the responsibility of another installer, notify Architect of unsatisfactory preparation before proceeding. The coating supplier should also certify the compatibility of the primer with portland cement based fireproofing. This method measures the volume of the material without the need for thickness or area measurements.
Find over more construction specifications Arcat. This would result in an overstatement of the protection level, which must be avoided.
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.
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 These fire-resistive materials include sprayed fibrous and cementitious materials.
These compounds may impair proper bonding of fireproofing to the substrate. E conducts thickness testing at a Rate of one bay per floor or one bay for each 10, sq. The test method is applicable to both laboratory and field procedures as indicated in Section 7. My question is after setting the cap with epoxy and letting it set asrm approximately 24 hours are we to cut around the cap to asstm substrate or are we to test it in-place without cutting around the cap? We recommend that Section Metal Decking states: It reduces some of the measuring and sampling variables that are inherent with other methods.
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. 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.
He stated the following: Steel deck manufacturer shall supply deck fire of lubricants or oils which would impair the adhesion of the spray applied fireproofing. The following is one example of how a mock-up on a large project might be specified. For every sq. We recommend the following be added to the structural steel specification: Grace and Company, which is located at: So, when writing an SOP for performing thickness determination the following could be adopted: When measuring density, IBC refers us to section 8.
The values stated in each ast, may not be exact equivalents; therefore, each system shall be used independently of the other.
ASTM International – Standard References for ASTM E / EM – 17
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. Maintain environmental conditions temperature, humidity, and ventilation within limits recommended by manufacturer for optimum results. Monokote MK-6 factory-blended cementitious fireproofing meeting the following physical performance standards:. Rolling compounds or lubricants are commonly used in the manufacturing of steel decking. It can be used to retest a sample that may be in question.
It makes no reference to Note 4 in using a correction formula. A firm which has at least three 3 years experience in work of the type required by this section. Provide a mock-up for wstm of surface preparation techniques and application workmanship. 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.
During a recent project we found the Sprayed Fire-Resistive Material applied to the aztm substrate to sound hollow upon surface tapping. 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 the steel deck.
Hold a pre-installation conference prior to commencement of field operations to establish procedures to maintain optimum working asmt and to coordinate this work with related and adjacent work. It is based on the same design concept of the original tested assembly s736 it is up to the design professional to determine if the increase in thickness compensates for the low density of the SFRM.
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.
As a laboratory we believe the measurements should be actual not allowables. Submit manufacturer’s approved drawings for all applicable construction details.
Grace Construction Products, which is located at: 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.
Manufactured with a mold inhibitor and shows resistance to mold growth for a period of 28 days for general use. The use of primer coatings with fireproofing is detailed in the UL Fire Resistance Directory and may require the use of bonding d736 or mechanical attachment on beams, columns, tube and pipe steel to maintain the fire-resistive rating.
Upon request, provide supporting documentation from an independent laboratory e763 to performance results listed in this section.
