ASTM burning testing is in 4 hour increments with trimming wick each time you light. As per the burning instructions on all candles bottom label.

Light 4 Life suggest testing a worst case scenario for extra safety precautions. Burn candles in your testing for 8 hours and do not trim wicks unless there is a very large mushroom top to see if glass gets too hot, bursts or fragrance flashes.

Warning: fragrance with flash point below 165 degrees may flash when using a high level of fragrance. Citrus fragrance is more prone to flashing. Do not use more than 12.5% fragrance in candles to ensure stability.  Lemongrass should be used at 7.5% .
