Chapter 4 Determination of the Combustibility or Explosibility of a Metal, Metal Powder, or Metal Dust
4.1 * Overview. The screening test in Section 4.2 or in Section 4.3 shall be conducted to determine if a metal is in combustible or explosible form.
4.1.1 If either of the tests produces a positive result, the ma- terial shall be considered a combustible metal.
4.1.2 Test results shall be documented, the AHJ shall be noti- fied, and the test results shall be provided when requested.
4.1.3 Documentation of noncombustibility proven through analytical testing of combustibility and explosibility of the spe- cific forms of these materials, as described in this chapter and acceptable to the AHJ, is required to eliminate application of this standard.
4.1.4 Application of This Document.
