EU candle safety is three standards, not one: EN 15493 for fire safety, EN 15426 for sooting behaviour, EN 15494 for the label on the jar. Most supplier spec sheets quote the first two and quietly skip the third. The label is where the other two show up in a form a customer can actually read, and it’s the one most often half-implemented.
One general sign, four specific
EN 15494 sets a floor, not a target. At minimum, a candle sold into the EU carries a general warning sign plus four mandatory specific warnings: keep away from combustibles, don’t leave unattended, keep out of reach of children and pets, and don’t burn beyond the stated duration or in a draft.
That requirement traces back to 2007, when the European Candle Manufacturers Association in Brussels pushed the first indoor candle safety set through CEN. Scented candles got their own block in 2015, outdoor candles in 2021, accessories in 2023. The indoor label requirements have been stable since the 2019 revision. That stability is worth exploiting: the four marks don’t change between a 120 g tealight and a 500 g pillar.
In our factory runs the label file lands later than the pour spec, and that’s where the failures hide. The wax passes EN 15426, the flame passes EN 15493, and the jar ships with two of the four marks because the printer was cheap on line count. The customer can’t read what the spec required. Check the label file against the current standard, not the previous label. The prior label inherited the gap.
The two tests behind the marks
EN 15426 covers sooting behaviour on single-wick candles up to 100 mm diameter. It scores the flame, not a particulate count on the wax. A sooty flame means the wax-and-wick combination is out of range, and the fix is a wick size change or a blend shift. Re-running the same spec doesn’t change the result.
EN 15493 covers fire safety: flame behaviour, melt pool spread against the container wall, and the wax-and-container combination under a defined burn sequence. The 2026 revision, published September 30, is now current. IFS, TUV, and Intertek all run the set, so ask for the lab name and the test date. A certificate without both is a photo, not a document.
The 100 mm line matters more than it should. Above it, EN 15426 no longer applies to single-wick candles, and multi-wick designs need their own test case. That’s a design decision at the wax stage, not a fix at the label stage. We’ve seen a 120 mm pillar pass a 90 mm test and fail on its own melt pool, because the wall area the flame sees is different and the spec doesn’t carry over.
Three items to pull before you order
First, the wax-and-wick ratio with the EN 15426 sooting score, not just pass or fail. The score tells you how much margin you have before a wick size change pushes the flame back into soot range. Second, the EN 15493 date and lab. A 2019 test is a 2019 spec, and the 2026 revision is current. Third, the five labels, printed, on the actual jar, in the buyer’s language. Not on a data sheet, not on the invoice. On the jar.
If the supplier can’t give you the first two, they aren’t testing to the standard. If they can’t give you the third in the buyer’s language, they aren’t labelling to spec. Both are fixable, and both cost more after a complaint than before a quote. The label is the cheapest spec to fix and the hardest to find after a recall. Get it printed, in the right language, on the actual jar, before the carton goes on the pallet.
