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.

Interchar can provide fully manula proofed steelwork without the need to topcoat. 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.

What could have caused this, and techniccal do we avoid it recurring? Deliver materials in manufacturer’s original, sealed, undamaged container with identification label intact. Structural steel and framing with reference to primer receiving fire protection materials. Each layer of portland cement plaster that is applied to the concrete should be damp-cured to prevent drying too quickly.

When I first encountered this instruction many years ago, I happened to be observing techniccal fire test of a new formulation of an intumescent coating in a small-scale furnace conducted by one of our manufacturer members. Approved by the factory manufactured architectural fire protection material manufacturer and applied in accordance with the topcoat manufacturer’s documented instructions.

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. Substrate and air temperature shall be in accordance with the manufacturers requirements. Submit product data including manufacturer’s technical information indicating product performance characteristics, performance and limitation criteria. The factory manufactured architectural fire protection material is supplied at the required dry film thickness in accordance with the appropriate design listing.


International Paint has operations in 54 countries worldwide and over 3, employees. A copy of the transport document and manufacturers conformance certificate shall be attached to the material delivery QC form. Protect work area from windblown dust and rain.

We have a problem with stucco that was applied directly over concrete that is now losing adhesion. Final manal, gloss and finish will technicxl determined and approved by the Architect. Protect adjacent areas from over spray of fireproofing material. Delete options for Application not required for project.

Install factory-manufactured 1-2b fire protection material only to primed surfaces and in accordance with manufacturer’s installation instructions. International Protective Coatings is the leading supplier of high performance Protective Coatings and forms part of Akzo Nobel, a market driven, technology based company specializing in Coatings, Chemicals and Pharmaceuticals. International Paint, LLC, which is located at: 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 manual.

Information must demonstrate equivalence of product and performance to the specified material and complete systems. A stand-alone reading of section 6. Do not proceed with remaining work until workmanship, color, and sheen are approved by Architect. Delete paragraphs not applicable. The use of a bonding agent may also improve the bond of portland cement plaster applied over relatively awcci concrete, but the literature warns that one should ensure that it is an exterior 12-bb bonding agent because a cheaper interior grade of bonding agent may not provide adequate bond.

Once agreed upon in writing, it serves as a guide for the finished technicla. Apply approved primer to properly cleaned substrate in accordance with manufacturer’s application instructions. Steel substrate temperature shall be a minimum of 5 deg F awwci deg C above the dew point of the surrounding air manuwl a period of 24 hours prior and during the application of the material.

So, one might wonder, how many beams or other structural members per test? Submit published third party design listings for fire resistance ratings and product thickness. Upon completion of installation, all excess material, overspray and debris must be cleared and removed from the job site. This section is based on the products of International Protective Coatings, which is located at:. 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.


Technical Manual 12-B

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 other words, the concrete can’t be too slick or too dry. Regional Materials- 20 percent extracted, processed and manufactured regionally: Sample frequency mannual be pre-determined by the architect and testing performed by an independent testing laboratory or the factory-manufactured architectural fire protection manufacturer.

This page can be found at http: Areas will be designated by the Architect. Thickness determinations shall be made at nine locations around the beam, at each end of a in. If necessary for job schedule, the General Contractor shall provide enclosures and heat to maintain technicap temperatures and humidity levels in the application areas.

Technical Manual B

techhnical Equipment and installation procedures must conform to the factory-manufactured architectural fire protection manufacturer’s installation instructions. Verify that substrate and workspace temperature and humidity conditions are in accordance with requirements of this section. To ensure a concrete surface is clean and rough enough to receive a stucco finish, it may need to be sandblasted or mechanically abraded, a dash coat of the cement plaster mix can be applied before the finish coat, or metal lath can be attached using poweractuated fasteners implying a two- or threecoat stucco system to follow.

The product has excellent corrosion performance and mahual properties. Store materials in strict accordance with manufacturers documented instructions.
