Standard Test Method for Collection and Analysis of Visible Emissions from Candles as They Burn

This test method is intended to provide candle manufacturers a standard procedure to use during development of candle designs and formulations to compare relative smoke/burn behavior. For the development of this method, a protocol was established for trimming the wick on specially prepared test candles to 6 mm to 7 mm (1/4 in.) prior to each burn cycle. It is recommended that the manufacturer determine a standardized protocol, that is, either not trimming the wick or trimming the wick to an appropriate length in order for direct comparison of results.
