Revise A.5.6 to read as follows: A.5.6 Specification of the type, amount, and arrangement of combustibles for any commodity classification is essentially an attempt to define the potential fire severity, based on its burning 5 ch

21、aracteristics, so the fire can be successfully controlled by the prescribed sprinkler protection for the commodity class. In actual storage situations, however, many storage arrays do not fit precisely into one of the fundamental classifications; therefore, the user needs to make judgments after com

22、paring each classification to the existing storage conditions. Storage arrays consist of thousands of products, which makes it impossible to specify all the acceptable variations for any class. As an alternative, a variety of common products are classified in this annex based on judgment, loss exper

23、ience, and fire test results. Table A.5.6 provides examples of commodities not addressed by the classifications in Section 5.6. The commodities listed in Table A.5.6 are outside the scope of NFPA 13 protection. Table A.5.6.3 is an alphabetized list of commodities with corresponding classifications.

24、Tables A.5.6.3.1, A.5.6.3.2, A.5.6.3.3, A.5.6.3.4, and A.5.6.4.1 provide examples of commodities within a specific class. 7.
