Repeatability and Raproducibility of Fire Tests for Cigarette Ignition of Upholstered Furniture Composites

摘要

An analysis has been made to compare the repeatability and reproductibility of three tests for cigarette ignition of upholstered furniture composites: ASTM E1352, ASTM E1353 and INST 851 mock-up. The first two of these tests are traditional methods designed to assess the potential of upholstered furniture components to being ignited by cigarettes while the last one, NIST 851 mock-up, is a new method designed to assess the propensity of cigarettes to ignite upholstered furniture composites. The traditional methods, ASTM E1352 and ASTM E1353 use a single cigarette for each determination and can be run in two ways: to obtain a numerical output of char length on the substrate (following the standard) or to obtain a pass/fail result for the substrate (practical sue); the precision was analysed in both fashions.
