Submit manufacturer’s written installation instructions. The wording of the instructions for testing the film thickness of Thin- Film Intumescent Fire-Resistive Materials on structural members in Technical Manual B can indeed be a bit confusing, especially when read without having first read the earlier passages in the aci. Some argue that when testing a beam, the thickness must be tested in nine locations around the beam every 12 inches. Company specializing in installing the work of this section with a minimum of three 12-h documented experience and certified by the material manufacturer.
Thickness determinations shall be made at nine locations around the beam, at each end of a in. Remove fire protection materials from surfaces not required to be fireproofed.
Each layer of portland cement plaster that is applied to the concrete should be damp-cured to prevent drying too quickly. Information must demonstrate equivalence of product and performance to the specified material and complete systems.
SECTION ARCHITECTURAL INTUMESCENT FIRE PROTECTION
Delete the next paragraph if not applicable. Packaged materials must bear the appropriate labels, seals and designated certification mark for fire resistive ratings.
Published by Construction Dimensions. Install factory-manufactured architectural fire protection material only to primed surfaces and in accordance with manufacturer’s installation instructions. Delete options for Application not required for project. Primer applied at the steel fabricators shop must be in accordance with the provisions of Section Apply decorative top coat in accordance with the manufacturer’s application instructions.
Factory manufactured architectural fire protection system will be a complete system from a single source consisting of primer, factory manufactured fire protection sections, section adhesive, edge sealant and decorative topcoat. Steel substrate temperature shall be a minimum of 5 deg F 3 deg C above the dew point of the surrounding air for a period of 24 hours prior and during the application of technicaal material. Approved by the factory manufactured architectural fire protection material manufacturer and applied in accordance with the topcoat manufacturer’s documented instructions.
International Protective Coatings is the leading supplier of high performance Tecjnical Coatings and forms part of Akzo Nobel, a market driven, technology based company specializing in Coatings, Chemicals and Pharmaceuticals. The relative humidity of the application area shall mabual exceed a maximum of 85 percent for 24 hours prior, during and 24 hours after the application of the material.
Store materials in strict accordance with manufacturers documented instructions. Substrate and air temperature shall be in accordance with the manufacturers requirements. This page can be found at http: This section is based on the products of International Protective Coatings, which is located at:.
A stand-alone reading of section 6. All batch number, product identification and quantities shall be recorded on etchnical QC documents. Manjal products listed in this section must be manufactured under the appropriate texhnical service with each container bearing the certified label mark. Approved by the factory manufactured architectural fire protection manufacturer and applied in accordance with the primer manufacturers documented instructions.
All test results must be made available to all parties at the completion of each pre-designated area and approved prior to the application of top-coat. A pair of measurements 12 inches apart on a given beam in no particular, random location along the beam — the tested area could be near an end or in the middle of the span.
AWCI’s Construction Dimensions – October 2013
The concrete could also have been considerably drier than the portland cement plaster when technucal was applied and absorbed too much of the moisture from the mix to technjcal proper curing. Send your questions to jones awci. Store and dispose of hazardous materials, and materials contaminated by hazardous materials, in accordance with requirements of local authorities having jurisdiction.
In-place fire protection material not in compliance with the specification requirements must be corrected prior to the application of the decorative top coat. There are several diagrams in B, but they are cross-sections of a beam, a column, a tube and a truss; the cross section of the beam includes arrows indicating the nine points around the beam where the xwci thickness of the TFIFRM is to be measured.
Technical Manual B
Jones is AWCI’s director of technical services. Requests for substitutions must manuap made 30 days prior to submittal and contain the full name of each product, descriptive literature, testing data collected from industry consensus standard testing, data on past performance, manufacturer’s instruction for use and generic type.
We have a problem with stucco tdchnical was applied directly over concrete that is now losing adhesion. Interchar is primarily a spray applied material, and performs awcci the requirement for any reinforcement. What could have caused this, and how do we avoid it recurring? A concrete surface could be too slick because it has been coated with some kind of sealer, or the forms left a tight surface that was not roughed up or otherwise pretreated before the plaster was applied.
Prior to mixing Mannual A and B of the adhesive and edge sealant during the installation of the architectural decorative fire protection material, random pre-determined liquid samples of Part A and Part B must be submitted for material characterization fingerprinting in accordance with the procedures detailed in the ISO Standard. Delete paragraphs not applicable.
Provide ventilation in areas to receive work of this section during application and minimum 24 hours after application. The product has excellent corrosion performance and mechanical properties. The factory manufactured architectural fire protection material is supplied at the required dry film thickness in accordance with the appropriate design listing.
