Assuming that the readings are normally distributed this implies that: All advice given or statements made about the product. These are the correction factors for maximum and minimum thickness kmax and kmin.
The temperatures of all parts of the section are increased. It is therefore important that the steel web temperature needs to be controlled. The critical temperature may be different for columns and beams and therefore two design temperatures may be used in the assessment.
Export Data and Price of products under HS Code | Zauba
The analysis may be repeated at other critical temperatures. All these codes cover the design of a number of types of steel element and include the calculation of the temperatures of fire protected steel. Where the thick web is not sufficient to compensate for the loss in strength of the flange.
Application technique Air-borne spray mixed with water at gun 6. Fire resisting floor assemblies construction details are given in the assessment reports for up to2 hrs.
Attach web pieces to noggins with Pig Tail Screws at mm centres.
In both 9733 and the new European Standards the fire resistance performance of an element is judged against the three criteria of load-bearing capacity. Loaded beams shall be tested with their ends simply supported. If you do not fully understand these warnings and instructions or if you cannot strictly comply with them, do not use the product and consult International Protective Coatings.
No preparation is necessary for box protection 7.
It is well documented that the ability of structural steel components to support load varies with temperature. Intercha resistance range Up to 4 hours To provide an indication of the behaviour of protected asymmetrical sections.
Kapelle-op-den-bo s Belgium Insulation boards produced from mixing vermiculite with inorganic binders. Beams BS EN That situation has now changed. The web post line must not be extrapolated below mm unless additional test results can prove otherwise. Assessments for circular sections may normally be based on tests on square sections having the same Section Factor. Nullifire Ltd ProtegaFire S General assessment procedures are referred to in Section 3.
Fire Resistance Period The fire resistance period of each tested loaded steel section is the duration of the test until the specimen is no longer able to support the test load see Section 1. When loaded beams are tested with short columns. This ratio should intedchar plotted against web post width. This a special type of thermocouple used for measuring the temperature within the furnace. Similarly an assessment need not cover all the steelwork shapes.
Contact Promat Technical Services for advice. Board butt joints glued. All work involving the application and use of this product should be performed in compliance with all relevant national Health, Safety and Environmental standards, regulations and legislation.

See remarks Name of Name of Report No. This information is used in both the UK and European methods of assessing fire protection materials.
The correction for the short beams is based on interpolation between the performance at maximum and minimum protection thickness. Up to 3 hours fire protection. If any zone does not meet this requirement. The temperature of the steel at failure will vary. 9773 immersion service or service in humid conditions or elevated temperatures, this product should. On site use For internal applications only It is willing to make its specialist knowledge on all aspects of fire protection and can assist specifiers and main contractors in identifying products suitable for specific requirements, both in the UK and related overseas markets.
Number of coats The number of coats to build the required thickness may affect the overall performance of the coating. Association for Specialist Fire Protection 63 Fire protection for structural steel in buildings th www. The assessment can be limited to 3 and 4 niterchar protection beams and columns or 4 sided protection columns only at the request of the test sponsor.
E — Columnclad encasement stable fixed to web noggins at max. The use of reactive coatings intumescent paints is discussed in 6.
Catalog | Kaung United Co.,Ltd
Loaded specimens should comply with the dimensional requirements of BS or ENV and non-loaded specimens used to provide temperature data should have a length of at least 1 metre. Direct Application of Results Permitted extensions are given in section 5.
Application technique 4-sided column encasement 9773 mm wide ColumnClad noggins wedged between flanges. It is therefore advisable to include a mm deep web unloaded beam and a mm wide flange unloaded beam in the test programme.
The coefficients are used to predict the thickness of protection material required to provide specified fire resistance periods to various section factors for various design temperatures.
