Abstract : There is currently no test designed specifically to test the spread of flame on nonmetallic piping. Such a test is required to meet the International Maritime Organization's requirements for use of nonmetallic pipe on board vessels. This work considers the suitability of two modified tests and their acceptance criteria for meeting this testing requirement. The two tests are (a) the IEC publication 332-3 (Flame Spread Test for Electric Cable) as modified by IMO FP 33/11/4 and (b) the Test for Surface Flammability for Bulkhead, Ceiling, and Deck Finish Materials, IMO Resolution A.653(16). Both tests were found to be executable. Data collected using the IEC test procedure was highly dependent on the test geometry. A method to 'correct' this data to a set of standard conditions was developed. Theory predicts that data obtained from the IMO test procedure should also depend on test geometry. In most instances the data did not reflect this dependency. Several geometrically sensitive parameters were involved in each test. The effects of these parameters appear to be offsetting for the conditions tested. jg
