BS EN 15426 discusses sooting behaviour of candles. BS EN 15426 specifies requirements and the test method for evaluating the sooting behaviour of burning indoor candles.
Note1: BS EN 15426 is applicable to single wick candles with a diameter up to 100 mm or equivalent cross-sectional area intended to be burned indoors.
Note2: Single wick candles with a diameter above 100 mm or equivalent cross-sectional area and multi-wick candles cannot be evaluated with this test method for technical reasons. Evaluation of the visible release of soot is a possibility for these candles.
BS EN 15426 on the sooting behaviour of candles is useful for:
Candles have accompanied mankind for more than 2 000 years serving as a light source. Connected to the development history of the candle are the efforts made to improve its quality and its safety in use. Discussions in the past and present over possible self-forming, harmful emissions and fires caused by unsafe candles and/or inappropriate use during the burning of candles have led to consumer concern for these issues.
BS EN 15426 describes the requirements and a simple method for measuring the sooting behaviour of candles. The soot index obtained by this procedure may be considered as characteristic of the sooting behaviour of the type of candle tested.
BS EN 15426 helps to ensure a reasonable degree of safety during use, thereby improving personal safety and reducing the risk of fires, deaths, and injuries.
To keep damages caused by candle soot to homes and to the health of their residents to a minimum, the BS EN 15426 suggests a standard test protocol that allows manufacturers to measure the amount of soot emissions.
