(Amendment)Chimneys - Accessories - Part 3: Draught regulators, standstill opening devices and combined secondary air devices - Requirements and test methods
General Information
- Abstract
This European standard specifies the requirements and test methods for draught regulators and standstill opening devices that are used as components, carrying flue gases, in order to limit the draught in chimneys and provide secondary air to the chimney.
Draught regulators and standstill opening devices for positive pressure chimneys are not covered by this standard.
It also specifies the requirements for marking, manufacturers’ instruction, product information and evaluation of conformity.

Overview
EN 16475-3:2016/prA1 is a CEN European standard that specifies requirements and test methods for chimney accessories used to limit draught and to provide secondary air. The standard covers draught regulators, standstill opening devices and combined secondary air devices that form part of flue-carrying components. It excludes devices intended for positive pressure chimneys. The amendment prA1 (2017/2018) updates reaction-to-fire requirements and surface-temperature limits during heat and soot-fire tests.
Key topics and requirements
- Product scope: Draught regulators, standstill opening devices and combined secondary air devices used in chimneys (excluding positive pressure chimneys).
- Functional requirements: Devices must reliably limit draught and, where applicable, supply secondary air to the chimney system.
- Test methods: Defined laboratory tests evaluate performance, reaction to fire and resistance during heat stress and soot-fire scenarios.
- Reaction to fire: Must be declared after testing to EN 13501-1 or by classification without testing for materials inherently classified A1 (see referenced Commission Decision).
- Surface temperature limits (amendment prA1):
- Maximum surface temperature of combustible materials adjacent to the device shall not exceed 85 °C during the heat stress test (related to 20 °C ambient at the declared distance).
- Maximum surface temperature adjacent to draught regulators shall not exceed 100 °C during the soot-fire resistance test (related to 20 °C ambient at the declared distance).
- Marking and documentation: Specifies requirements for marking, manufacturer’s instructions, product information and evaluation of conformity to ensure traceability and safe installation.
Applications and who uses it
- Manufacturers and designers of chimney accessories use the standard to design compliant draught regulators and standstill opening devices and to define test protocols.
- Test laboratories and certification bodies rely on the standard’s test methods and conformity evaluation clauses to certify products.
- Chimney installers, HVAC contractors and building engineers use EN 16475-3 to select appropriate accessories that meet fire safety and thermal limits for safe installation.
- Specifiers and procurement teams include the standard in technical specifications for building projects, safety assessments and regulatory compliance.

- EN 13501-1 - Reaction to fire classification of construction products and building elements (referenced for fire testing).
- Other parts of the EN 16475 series (chimney accessories) as applicable.
EN 16475-3:2016/prA1 is essential for ensuring chimney accessory safety, predictable performance and conformity with European fire and thermal safety expectations.
