Fire Resistance

Generally, it means that the common criteria for a fire resistance rating generally means the duration for which a passive fire protection can fire against a hardness test. Although these are now easily quantified as a measure of the cost and time, or it can lead to a variety of other criteria, which other evidence of functionality or fitness for a particular purpose.
There are many international variations for almost innumerable species on the use of products and systems, some with several requirements.

TESTS

The tests of the Free spray fireproof methods are needed to place qualified hydrocarbon curve may require a series of environmental tests before burning occurs, to minimize the probability that the normal operating environments may not render an important component system unusable before she encounters a fire.
If critical ecological conditions are not met, or even if a meeting may not be entitled to a fire resistance rating.

DIFFERENCES

Because of the large differences in the test regime in the whole world, even for identical products and systems, organizations, which intend to make their products internationally are often required to numerous tests in many countries of the world. Even where the same test regime are often not to accept the test results and, above all, the certification of methods in other countries.

When a fire in a tunnel, as well as in the petrochemical industry, the temperatures are higher than those of normal building, the cellulosic, fire. This is because the fuel for the fire is hydrocarbons, which burn hotter, faster and usually not more fuel faster than good, compared to wood. The additional complication of the tunnel is that the environment in a pipe is best described as a micro-climate. The heat can not escape, as well as he can in a burning refinery, which is outdoors.

Instead, the fire is on a narrow tube, where pressure and heat build up and quickly, with little room for escape and little chance of demarcation.
In addition to following the series of images shows a typical test fire, in this case for a fire stop, to an active fire resistance rating, by the active product certification. A copy of the resulting list can be certified under the certification list.
