Also I would encourage you and your team to use the displacement method for determining density, Section 8. We recommend that Section Metal Decking states: Link to Active This link will always route to the current Active version of the standard.
Agenda for meeting will include review of special details and flashing. 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.
You are correct, the averaging calculations for thickness measurements as mentioned in ASTM E section 8.
Prepare surfaces using the methods recommended by the manufacturer for achieving the best result for the substrate under astn project conditions. It would be appropriate to mention the alternate method for determining the in-place density stated, in ASTM E Section 8.
When this question was asked of Luke Woods of W. For every sq. It makes no reference to Note 4 in using a correction formula. Sample surface “as applied” not pre-purged and the total measured as total axtm loss over a 24 hour period. Provide a mock-up for evaluation of surface preparation techniques and application workmanship. Do not install products under environmental conditions outside manufacturer’s absolute limits.
Provide schedule indicating material to be used, building elements to be protected with spray applied fireproofing, hourly rating and material thickness provided asm appropriate references.
Maintain environmental conditions temperature, humidity, and ventilation within limits recommended by manufacturer for optimum results.
Mechanical attachment is required on unclassified painted steel decks to maintain the fire-resistive rating. Classification is achieved by prior large-scale fire testing at UL with the specified fireproofing material. Grace and Company, which asm located at: E conducts thickness testing at a Rate of e763 bay per floor or one bay for each 10, sq.
Grace Construction Products, which is located at: From a practical viewpoint, the use of actual measurements for density calculations prevents “false high” density calculations.
This change has drastically increased the amount of testing on fluted decks.
However the user should be cautious as to the extent of the reference. A firm which has at least three 3 years experience in work of the type required by this section.
ASTM International – Standard References for ASTM E / EM – 17
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. If we go back to the IBC When measuring density, IBC refers us to section 8. Rolling compounds or lubricants are commonly used in the manufacturing of steel decking. Prior to application of the fireproofing material over concrete, apply a bonding agent approved by the fireproofing material manufacturer. Clips, hangers, support sleeves and other attachments required to penetrate the fireproofing, must be in place prior to application of the fireproofing materials.
Do not proceed with remaining work until workmanship, color, and sheen are approved by Architect. Cementitious fireproofing shall be manufactured and marketed by a single firm with a minimum of twenty 20 years experience in the production and sales of cementitious fireproofing. And Note 4 states the following: This would result in an overstatement of the protection level, which must be avoided.
Testing Engineers – Case Studies
Ducts, piping, equipment or other suspended items are not to be installed until the fireproofing is complete. Priming of interior structural steel is generally unnecessary, adds to the cost of the structure and may adversely affect the fire resistance rating and the bond of the fireproofing to the substrate.
Upon request, provide supporting documentation from an independent axtm attesting to performance results listed in this section. It reduces some of the measuring and sampling variables that are inherent with other methods.
On the other hand, IBC Less than 6 cc when subjected to impact penetration 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.
Performance criteria include resistance to damage, bond strength, air erosion and mold resistance sstm. The results of the above tests shall be made available to all parties at the completion of pre-designated areas determined during the ast, conference. Bond Strength of E73. Follow the material manufacturer’s application instructions for guidelines on equipment and application procedures.
Hold a pre-installation conference prior to commencement of field operations to establish procedures to maintain optimum working conditions and to coordinate this work with related and adjacent work. 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.
As a laboratory we believe the measurements should be actual not allowables. Find over more construction specifications Arcat.
