The physical performance criteria recommended above establish minimum levels of acceptable in-place performance for structural steel fire protection.
My question is after setting the cap with epoxy and letting it set for approximately 24 hours are we to cut around the cap to atsm substrate or are we to test it astj without cutting around the cap? For every sq. So, when writing an SOP for performing thickness determination the following could be adopted: From a practical viewpoint, the use of actual measurements for density calculations prevents “false high” density 7e36.
We recommend that Section Metal Decking states: Grace Construction Products, which is located at: The test method is applicable to both laboratory and field procedures as indicated in Section 7. 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.
Also I would axtm you and your team to use the displacement method for determining density, Section 8. For each finish product specified, two samples, minimum size 6 inches mm square, representing actual product, color, and patterns. Patching or repair spray applied fireproofing using the same materials under this section.
We recommend the following be added to the structural steel specification: Rolling compounds or lubricants are commonly used in the manufacturing of steel decking. Many of the world’s most challenging building problems have been solved by Grace’s premium construction chemicals and building materials. Maintain environmental conditions temperature, humidity, and ventilation within limits recommended by manufacturer for optimum results.
If the density of the SFRM does not meet the design criteria can an increase of thickness compensate for wstm deficient density? When this question was asked of Luke Woods of W. The coating supplier should also certify the compatibility of the primer with portland cement based fireproofing. It reduces some of the measuring and sampling variables that are inherent with other methods.
Testing Engineers – Case Studies
This would result in an overstatement of the protection level, which e76 be avoided. Agenda for meeting will include review of special details and flashing. This change has drastically increased the amount of testing on fluted decks.
Classification is achieved by prior large-scale fire testing at UL with the specified fireproofing material. With such a significant discrepancy between the two can you explain the right procedure?
Sample surface “as applied” not pre-purged and the total measured as total weight loss over a 24 hour period. Follow the material manufacturer’s application instructions for guidelines on equipment and application procedures.
These fire-resistive materials include sprayed fibrous and cementitious materials. Requests for substitutions will be considered in accordance with provisions of Section When deciding on the extent of the mock-up, consider all the major different types of work on the project.
Delete one of the next two paragraphs. Prepare surfaces using the methods recommended by the manufacturer for achieving the best result for the substrate under the project conditions.
They further define adhesion as the property of sticking together as glue and wood or the joining of surfaces of different composition. Clips, hangers, support sleeves and other attachments required to penetrate the fireproofing, must be in place prior to application of the fireproofing materials. Historical Version s – view previous versions of standard.
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. Max deformation of 10 percent when subjected to compressive forces of 57 KPa psf. For SFRM to provide the required level of protection both the minimum average thickness and the density requirements must be met.
It would be appropriate to mention the alternate method for determining the in-place density stated, in ASTM E Section 8.
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. Where cellular decking is present, include a requirement in Section 2.
This section is based on the products of W. 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 asfm for the life of a building. Grace Construction Products offers a wide range of innovative specialty construction chemicals and materials that includes: Less than 6 cc when subjected to impact penetration tests in accordance with the test methods developed by aatm City of San Francisco, Bureau of Building Inspection.
By simply specifying awtm MK-6,” the fireproofing subcontractor can select the product that will provide the most efficient fire protection for the specific project conditions. Where density samples are of irregular shape, a displacement method approved by Underwriters Laboratories Inc. The direct application of spray applied fireproofing is only permitted on UL classified painted steel decks.
