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 film thickness of the TFIFRM is to be measured.
1-b product data including manufacturer’s technical information indicating product performance characteristics, performance and limitation criteria.
Each layer of portland cement plaster that is applied to the concrete should be damp-cured to prevent drying too quickly. Install factory-manufactured architectural fire protection material only to primed surfaces and in accordance with manufacturer’s installation instructions. The factory manufactured architectural fire protection material is supplied at the required dry film thickness in accordance with the appropriate design listing.
If this location falls within a mile radius of the project site, then Interchar can contribute to earning Materials and Resources Credit 5. Prior to mixing Part 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.
Thickness determinations shall be made at nine locations around the beam, at each end of a in. Apply approved primer to properly cleaned substrate in accordance with manufacturer’s application instructions.
The concrete 12b also have been considerably drier than the portland cement plaster when it was applied and absorbed too much of the moisture from the mix to ensure proper curing. All batch number, product identification and quantities shall be recorded on appropriate QC documents.
We have a problem with stucco that was applied directly over concrete that is now losing adhesion. What is the intended pattern? Approved by the factory manufactured architectural fire protection material manufacturer and applied in accordance with the topcoat manufacturer’s documented instructions.
Technical Manual B
After several failed attempts to explain this testing procedure to me I first took it to mean one must measure near each end of the beam, 12 inches inthe technical sales rep wound up drawing a diagram that finally made it clear. Include evidence that the fire testing was sponsored by the manufacturer and that the material tested was produced at the manufacturers facility under the supervision of third party certification personnel. So, one might wonder, how many beams or other structural members per test?
That’s where reading the earlier material comes in handy. Once agreed upon in writing, it serves as a guide for the finished work. Requests for substitutions must be 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. 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.
Technical Manual 12-B
Upon completion of installation, all excess material, overspray and debris must be cleared and removed from 12-bb job site. The application must be witnessed by the Architect’s or Owner’s representative and is subject to their approval. Regional Materials- 20 percent extracted, processed and manufactured regionally: All patching and repair to factory-manufactured architectural fire protection material, due to damage technlcal other trades, will be performed under this section and paid for by the trade responsible for the damage.
Protect adjacent areas from over spray of fireproofing material. Verify that substrate and workspace temperature and humidity conditions are in accordance with requirements of this section. Submit published third party design listings for fire resistance ratings and product thickness. Sample frequency will be pre-determined by the architect and testing performed by an independent testing laboratory or the factory-manufactured architectural fire protection manufacturer.
Protect work area from windblown dust and rain. Submit manufacturer’s written installation instructions. Deliver materials in manufacturer’s original, sealed, undamaged container with identification label intact. Commencement of installation is acceptance of substrate.
SECTION ARCHITECTURAL INTUMESCENT FIRE PROTECTION
Grind smooth all weld spatter and defects prior to commencement of fire protection installation. The relative humidity of the application area shall not exceed a maximum of 85 percent for 24 hours prior, during and 24 hours after the application of the material.
Provide ventilation in areas to receive work of this section during application and minimum 24 hours after application. Architectural Fire Protection Installer: Areas will be designated by the Architect. The use of a bonding agent may also improve the bond of portland cement plaster applied over relatively slick concrete, but the literature warns that one should ensure that it is an exterior grade bonding agent because a cheaper interior grade of bonding agent may not provide adequate bond.
Patching must be performed by the qualified installer manuaal applied in accordance with the manufacturer’s installation instructions. Primer applied at the steel fabricators shop must be in accordance with the provisions of Section Store materials in strict accordance with manufacturers documented instructions.
At project closeout, provide to Owner or Owners Representative an executed copy of the manufacturer’s standard limited warranty against manufacturing defect, outlining its terms, conditions, and exclusions from coverage. In-place fire protection material not in tcehnical with the specification requirements must be corrected prior to the application of the decorative top coat.
