Detailed Standards Coverage

EN 1278:2026 - Chemicals Used for Treatment of Water Intended for Human Consumption—Ozone

Chemicals used for treatment of water intended for human consumption – Ozone

This European standard specifies the requirements and testing methods for ozone used in the treatment of water destined for human consumption. Ozone’s powerful oxidizing and disinfecting properties are leveraged extensively in water treatment plants around the globe. EN 1278:2026 details the physical and chemical characteristics of ozone, procedures for concentration measurement in gases, and rules for its safe handling and application.

The revised standard now includes harmonized classification of ozone according to the European CLP regulation, new threshold limits for ozone in air, reference to EU Biocidal Products Regulation (BPR) and EU REACH compliance for product authorization, as well as links with device-related safety now specified in EN 17971. Importantly, it provides updated purity criteria, methods for analytical determination, and handling protocols to protect workers and end-users.

Key requirements:

• Only in-situ generated ozone is allowed for water treatment; transport/storage of ozone is not feasible due to instability.
• Ozone concentration must be specified by device manufacturers and comply with strict purity and impurity limits, especially for by-products like nitrogen oxides.
• Safe handling includes strict adherence to GHS hazard communications (Danger, multiple hazard statements).
• Users must reference national regulations and verify suitability for potable water application.

Target Organizations:

• Water utilities, treatment plants, device manufacturers, regulatory agencies, and any organization responsible for drinking water safety.

Key highlights:

• Stronger integration with EU BPR and REACH for biocidal and non-biocidal use
• More robust purity, safety, and labelling criteria
• Device-related safety transferred to complementary standards (EN 17971)

Biological durability of wood and wood-based products – Quantitative determination of pentachlorophenol in wood – Gas chromatographic method

EN 14823:2026 offers a standardized laboratory method for detecting and quantifying pentachlorophenol (PCP) in wood, wood-based panels, and waste timber, utilizing gas chromatography. This is crucial for construction products compliance, particularly as PCP is a persistent pollutant linked to health and environmental risks. The updated standard reflects a full technical revision, including results from a comprehensive round robin test that confirmed its reliability.

Scope and method:

• Measures PCP levels in wood from 250 μg/kg to 5 mg/kg (adjustable by altering the extracted volume for lower quantification limits)
• Extraction, derivatization with acetic anhydride, and detection by either electron capture or mass spectrometry are specified, ensuring flexibility for complex matrices such as hardwoods
• Strict protocols for sample preparation, calibration, test execution, and result expression, promoting reproducibility and comparability across laboratories

Target Organizations:

• Timber processors, facilities dealing with reused or waste wood, building materials manufacturers, testing laboratories, and regulatory authorities overseeing construction product legislation

Key highlights:

• Extends quantification to both new and waste timber products
• Fully revised technical content, including validation via inter-laboratory studies
• Accommodates complex matrices through optional MS detection

EN 15493:2026 - Candles—Specification for Fire Safety

Candles – Specification for fire safety

EN 15493:2026 specifies requirements and test methods for indoor candle fire safety, crucial for minimizing risks of fire, injuries, and property damage associated with candle use. The 2026 revision builds on previous editions by refining definitions, introducing new requirements for container and multi-wick candles, and specifying testing for container flammability. All aspects—from flame height and aftersmoke duration to the structural integrity of containers—are addressed with clear testing procedures and pass/fail criteria.

Scope and features:

• Maximum flame height constraints: 75 mm for most, 30 mm for tealights
• Strict stability, self-extinguishing, and aftersmoke requirements to prevent accidental ignition or injury
• Explicit testing and performance standards for multi-wick and container candles, including protocols for container breakage and surface temperature
• Manufactured candles must be tested as supplied, including with holders or accessories if sold together

Target Organizations:

• Candle manufacturers, importers, retailers, testing laboratories, and consumer safety bodies

Key highlights:

• Comprehensive safety requirements covering all candle types
• New standardized test methods for container flammability and multi-wick behavior
• Enhanced guidance for identifying and preventing fire hazards in domestic environments
