The plausible universe of alternatives to decaBDE for achieving fire safety in TV enclosures includes chemical substitutes, inherently flame resistant materials that eliminate the need for added flame retardant chemicals (for example, steel or aluminum), and TV re-design options that eliminate the need for flame retardants by separating the enclosure from the heat source. Alternative enclosure designs that eliminate the need for added chemical flame retardants and meet or exceed performance specifications (including flame retardancy) are considered inherently preferable alternatives, particularly if they are derived from benign chemicals (and safe processes) and are recyclable or compostable at end of life.

The ASME STS-1 Steel Stacks [2] governing standard used in the design of steel stacks is important, and everyone should be familiar with it. In Example E.7 in the standard, the mass damping parameter is used as a... 

D4 The wear resistance of a steel gear is to be improved by hardening its surface, as described in Design Example 5.1. However, in this case, the initial carbon content of the steel is 0.15 wt%, and a carbon content of 0.75 wt% is to be established at a position 0.65 mm below the surface. Furthermore, the surface concentration is to be maintained constant, but may be varied between 1.2 and 1.4 wt% C. Specify an appropriate heat treatment in terms of surface carbon concentration and time, and for a temperature between lOOO C and 1200 C.
