The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other.
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. The direct application of spray applied fireproofing is only permitted on UL classified painted steel decks.
We recommend that Section Metal Decking states: Bond Strength of Fireproofing. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. E conducts thickness testing at a Rate of one bay per floor or one bay for each 10, sq. The IBC uses E for thickness determination but has wording that supersedes E on the rate of testing.
Follow the material e7736 application instructions for guidelines on equipment and application procedures.
Ducts, piping, equipment or other suspended items are not to be installed until the fireproofing is complete. Store and dispose of e73 materials, and materials used with solvent-based materials, in accordance with requirements of local authorities having jurisdiction.
Testing Engineers – Case Studies
The deck manufacturer shall certify that the primed steel deck is UL classified and has been fire tested with the appropriate fireproofing material. For SFRM to provide the required xstm of protection both the minimum average thickness and the density requirements must be met.
Provide schedule indicating material to be used, building elements to be protected with spray applied fireproofing, hourly rating and material thickness f736 and appropriate references. Manufactured with a mold inhibitor and shows resistance to xstm growth for a period of awtm days for general use. 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.
Referenced Documents purchase separately The documents listed below are referenced within the subject axtm but are not provided as part of the standard. They further define adhesion as the property of sticking together as glue and wood or the joining of surfaces of different composition. The concept of a correction formula has a valid basis and should not be considered as a loop hole or an easy way out. 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 the substrate or are we to test it in-place without cutting around the cap?
For each finish product specified, two samples, minimum size 6 inches mm square, representing actual product, color, and patterns. If we go back to the IBC This change has drastically increased the amount of testing on fluted decks.
Submit manufacturer’s approved drawings for all applicable construction details. Historical Version s – view previous versions of standard. Performance criteria include resistance to damage, bond strength, air erosion and mold resistance protection.
Provide a mock-up for evaluation of surface preparation techniques and application workmanship. These fire-resistive materials include sprayed fibrous and cementitious materials. Find over more construction specifications Arcat.
Combining values from the two systems may result in non-conformance with the standard. Grace Construction Products offers a wide range of innovative specialty construction chemicals and materials that includes: Prior to application of the wstm, 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 atm meet the fire resistance ratings.
So, when writing an SOP for performing thickness determination the following could be adopted: Delete one asttm the next two paragraphs. If substrate preparation is the responsibility of another installer, notify Architect of unsatisfactory preparation before proceeding. It makes no reference to Note 4 in using a correction formula. Classification is achieved by prior sstm fire testing at UL with the specified fireproofing material.
Patching or repair spray applied fireproofing using the same materials under this section. This method measures the volume of the aatm without the need for thickness or area measurements. For example, the work of e36 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. 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.
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. Prohibit qstm roof traffic upon commencement of the fireproofing and until the fireproofing material is dry.
Steel deck manufacturer shall supply deck fire of lubricants or oils which would impair the adhesion of the spray applied fireproofing. Provide accessories to comply with manufacturer’s recommendations and to meet fire resistance design and code requirements. Where density samples are of irregular shape, a displacement method approved by Underwriters Laboratories Inc. Consult the rating criteria.
Grace and Company; Cementitious Fireproofing. 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. From a practical viewpoint, the use zstm actual measurements for axtm calculations prevents “false high” density calculations.
Clips, hangers, support sleeves and other attachments required to penetrate the fireproofing, must be in place prior to application of the fireproofing materials.
You are astn, the averaging calculations for thickness measurements as mentioned in ASTM E section 8. It can be used to retest a sample that may be in question.
