This paper describes the results of a joint study undertaken by the U.S. Army Materials Technology Laboratory (AMTL) and the Factory Mutual Research Corporation CFMRC) on fiber reinforced composite materials (FRC) for use in a composite combat vehicle. 

The generation of material vapors can be quantified in terms of 1) relationship between weight loss and sample temperature. AMTL used thermogravimetric techniques for such quantification (J ), and 2) the relationship between the generation rate of material vapors and the heat flux. Factory Mutual Research Corporation (FMRC) has developed a technique using FMRC s Small-Scale Flammability Apparatus (2-10), which was used for the quantification.

This is an example of pressure modeling done at Factory Mutual Research (FM Global) by deRis, Kanury and Yuen [17] and Alpert [8]. In pressure modeling, Gr is preserved with pyj / 3/2 along. Therefore m"//p, is also preserved and... 

Certification. It is a benefit to the employer to ensure that the intrinsically safe electrical circuit is certified. Certification can be achieved through the use of a third party, such as Underwriters Laboratories or Factory Mutual Research. Both of these organizations have their own standards for approval which are based on NFPA 493. The certification is accomplished in three steps ... 

Availability. Both Underwriters Labatories and Factory Mutual Research publish yearly guides to electrical equipment which they have certified and continue to certify as being rated for use in hazardous environments. Many of the items contained in these guides are rated as intrinsically safe or as associated equipment for use with intrinsically safe equipment. Further, the amount of equipment available should increase each year as the demand increases for intrinsically safe electrical circuits.
