Fire, generally tests

The material and its installation should be designed to protect for a specific time period. For hydrocarbon fire exposure materials and their installation are generally tested to either UL 1 709 or ASTM El 529 to determine time-to-failure of different thicknesses and installation methods. It should be noted that the fire resistance rating is a measure of the ability of the installed material to withstand a specific "standard" fire. While these conditions closely match those in any given hydrocarbon fire, during actual fires the material may be exposed to conditions that may be more or less thermal intense, thus it can be expected to retain its integrity for a greater or lesser time.

Applying U.S. standards or safety methodology to product assessment increases the risks of nonconformity because there are fundamental technical and interpretation differences between the U.S. and EU views (ANSI/UL vs. EN/IEC). In the area of safety philosophy, the U.S. test agencies, known as Nationally Recognized Test Laboratory s (NRTL), stress fire and tests, whereas, the European bodies focus on shock and construction. Both camps generally consider all safety...

This test also requires special equipment and generally consists of three parts a preliminary ignition test, a fire penetration test and a spread of flame test. The specimen is subjected to radiant heat and a vacuum is applied to one side to simulate service conditions. A specified flame is applied to the test piece for various durations and the time for the flame to penetrate, as well as the maximum distance of flame spread, are noted. Glowing, flaming or dripping on the underside of the specimen are also taken into consideration. Results are classified as follows ... 

In general, testing of components will concentrate on the structural behaviour, considering the response in bending, tension and so on. Tests for resistance to corrosive attack and other environmental loadings will probably be best carried out on suitable laminate specimens. Exceptions will be where the structural response and the environment interact, such as corrosive attack on a stressed component. In addition, the response may be influenced by the geometry of the member, or its size, such as the response to fire. 

A key issue is the development and resolution of the so-called Single Burning Item test. Other European projects are covering the general testing of cables, FIPEC and one for advanced methods for the determination of fire effluent composition. 

Cone calorimetry (CC) is one of the most effective medium-sized polymer fire behavior tests. The principle of cone calorimeter experiments is based on the measurement of the decreasing oxygen concentration in the combustion gases of a sample subjected to a given heat flux, in general from 10 to 100 kW/m [83]. Figure 4 illustrates the experimental set-up of a cone calorimeter. Standardized in the United States (ASTM E 1354), the cone calorimeter test is also the subject of an international standard (ISO 5660). 

Flame Resistance. Traditionally, small-scale laboratory flammabiUty tests have been used to initially characterize foams (38). However, these do not reflect the performance of such materials in bulk form. Fire characteristics of thermal insulations for building appHcations are generally reported in the form of quaHtative or semiquantitative results from ASTM E84 or similar tunnel tests (39). Similar larger scale tests are used for aircraft and marine appHcations. 

The National Safety Council, National Fire Protection Association, and other similar organizations pubHsh technical information that describes general safety practices for use during the testing, handling, storage, and transport of sulfur (21,36—40). Each of these pubHcations include a Hst of references for additional health and safety information. 

Wood-fired power boilers are generally found at the mills where wood products are manufactured. They are fired with waste materials from the process, such as "hogged wood," sander dust, sawdust, bark, or process trim. Little information is available on gaseous emissions from wood-fired boilers, but extensive tests of particulate matter emissions are reported (19). These emissions range from 0.057 to 1.626 gm per dry standard cubic meter, with an average of 0.343 reported for 135 tests. Collection devices for particulate matter from wood-fired boilers are shown in Table 30-21.

The most important hardware items appeared to be the detectors themselves. The gas detection system gave frequent spurious alarms, and on both platforms the ultraviolet (UV) fire detectors were also prone to spurious activation from distant hot work for example, and had a limited ability to detect real fires. The tmreliability of these systems had a general effect on response time and would, overall, lengthen the time to respond. The second aspect which was related to hardware was fimction and performance testing of the emergency blowdown systems. It is critical that the workers believe the systems will work when required, and this can only be achieved by occasional use or at least fimction testing.
