Candles - Specification for sooting behaviour
This document specifies requirements and the test method for evaluating the sooting behaviour of burning indoor candles. It is applicable to single wick candles with a diameter up to 100 mm or equivalent cross sectional area intended to be burned indoors.
NOTE Single wick candles with a diameter above 100 mm or equivalent cross sectional area and multiwick candles cannot be evaluated with this test method for technical reasons. Evaluation of the visible release of soot is a possibility for these candles.
Kerzen - Spezifikation für das Rußverhalten
Dieses Dokument legt Anforderungen an das Prüfverfahren für die Beurteilung des Rußverhaltens bren-nender Kerzen für den Innenraum fest. Es ist anwendbar an Eindochtkerzen mit einem Durchmesser bis zu 100 mm oder einer entsprechenden Querschnittsfläche, die für den Abbrand im Innenraum bestimmt sind.
ANMERKUNG Eindochtkerzen mit einem Durchmesser von über 100 mm oder entsprechendem Querschnitt können aus technischen Gründen nicht anhand dieses Prüfverfahrens bewertet werden. Für solche Kerzen ist die Beurteilung der sichtbaren Rußfreisetzung eine Möglichkeit.
Bougies - Spécification relative à l'émission de suie
Le présent document spécifie les exigences et la méthode d’essai permettant d’évaluer l’émission de suie des bougies d’intérieur lors de leur combustion. Elle s’applique aux bougies à une mèche, d’un diamètre inférieur ou égal à 100 mm ou de section équivalente, destinées à être utilisées à l’intérieur.

Overview
EN 15426:2018 - "Candles - Specification for sooting behaviour" (CEN) defines a standardized test and acceptance criteria to evaluate the sooting behaviour of burning indoor candles. The standard applies to single-wick candles with a diameter up to 100 mm (or equivalent cross‑sectional area). It specifies the test setup, sampling, test conditions and reporting so that manufacturers and test laboratories can quantify soot emissions reliably. The standard supersedes EN 15426:2007 and is maintained by CEN/TC 369.
Key topics and technical requirements
- Scope and limitations
- Applicable to single‑wick indoor candles ≤ 100 mm diameter.
- Candles > 100 mm diameter or multiwick candles cannot be assessed using this method; visible soot release may be evaluated separately.
- Acceptance criterion
- The average soot index per hour from three tests must be less than 1.0/h.
- Test principle
- Soot emitted by a burning candle is collected on a heat‑resistant glass plate placed inside a wire mesh cylinder; light attenuation through the soiled plate is measured in a measuring chamber to derive a soot index.
- Essential equipment
- Wire mesh cylinder with adjustable stand (open screening area (60 ± 5) % per ISO 9044), two cylinder sizes for different candle diameters.
- Measurement unit (light source, light‑reflective chamber, photodiode and indicator instrument). First operation and calibration procedures are given in Annex A.
- Heat‑resistant glass plates (100 × 100 mm, thickness 3.5–4.5 mm) and calibration disk (neutral density glass).
- Test procedure highlights
- Minimum of three samples representative of the commercial product.
- Prepare samples per manufacturer instructions (wick trim, measure dimensions/mass); sample and room temperatures at (20 ± 5) °C, draught‑free environment.
- Defined stabilizing period, followed by measuring periods; remove the glass plate before extinguishing to avoid afterglow contamination.
- Additional guidance: selection/setup of wire mesh (Annex C) and hourly fuel consumption calculation (Annex B).
- Reporting
- Full test conditions, timings, dimensions, temperatures and the soot index results are recorded in the test report.
Applications and who uses it
- Candle manufacturers - product design, quality control and safety verification.
- Independent test laboratories - standardized testing for certification and compliance.
- Retailers and procurement - supplier validation and product safety checks.
- Regulatory bodies and standards organizations - consumer safety assessment and comparative evaluations.
- R&D teams - formulation and wick/design optimization to reduce soot.
Related standards
- ISO 9044:2016 (industrial woven wire cloth requirements referenced for wire mesh).
- EN 15426:2018 replaces EN 15426:2007; consult CEN for national implementations.

The SIST EN 15426:2019 standard provides a comprehensive specification for evaluating the sooting behaviour of burning indoor candles, specifically targeting single wick candles with a diameter of up to 100 mm or an equivalent cross-sectional area. The standard is crucial for manufacturers and consumers alike, ensuring that candles adhere to established safety and performance benchmarks regarding soot emission during combustion. One of the key strengths of this standard is its focused application, which allows for a clear understanding of the parameters that influence the sooting behaviour of indoor candles. This specificity helps manufacturers design products that are not only aesthetically pleasing but also contribute to a healthier indoor environment by minimizing soot release. The outlined test methods provide a systematic approach for assessing the visible release of soot, which is essential in maintaining air quality and enhancing user experience. Furthermore, the relevance of SIST EN 15426:2019 is heightened in an era where consumer awareness surrounding indoor air quality is increasingly significant. With the growing market for indoor candles, compliance with this standard can serve as a competitive advantage, emphasizing a commitment to quality and safety. The exclusion of multiwick candles and larger single wick candles from this standard underscores the need for tailored testing methods, inviting further research and development to address these products' specific challenges. Overall, the SIST EN 15426:2019 standard is a vital document that sets the groundwork for evaluating the sooting behaviour of indoor candles, ultimately guiding manufacturers towards creating safer and more efficient products for consumers.
SIST EN 15426:2019は、室内で使用するキャンドルのすすの挙動を評価するための要件と試験方法を明確に定めた重要な標準です。この標準は、直径100 mmまでの単一ウィックキャンドルを対象としており、そのため、特に室内での安全性や使用感が重視されています。 この文書の強みは、すすの生成を定量的に評価する方法を提供する点にあります。すすは室内空気の質に直接的な影響を与えるため、適切な試験が実施されることは、キャンドル製品の市場での信頼性を高める要素となります。この標準は、高品質なキャンドルを求める消費者にとっても有益です。 また、SIST EN 15426:2019は、キャンドルの使用に伴う潜在的な安全リスクを軽減するためのガイドラインとしての役割も果たします。特に、直径100 mmを超える単一ウィックキャンドルや複数ウィックキャンドルについては、この標準では評価が難しいことを明示しており、技術的理由からの制約を理解する助けとなります。この点が、製造者や規制機関にとっても重要な情報を提供し、製品開発や市場投入の際の意思決定を支援します。 SIST EN 15426:2019の適用範囲は明確で、室内使用専用のキャンドルについての詳細な仕様が示されているため、業界全体の品質基準を統一する上でも大きな役割を果たします。この標準に従うことで、キャンドル製造業者は製品の品質を維持しながら、消費者にとって安全で快適な使用体験を提供することができます。 以上のように、SIST EN 15426:2019は、キャンドルのすすの挙動に関する評価基準を確立する上で不可欠な標準であり、その関連性と強みによって、業界における重要な基準として位置づけられています。
