Overview
EN 13274-6:2001 - issued by CEN - defines a standardized test method for determining the carbon dioxide (CO2) content of inhaled air (dead space) in respiratory protective devices. It is a supplement to device-specific standards and is intended for laboratory measurement of CO2 retained within facepieces, hoods or complete respiratory equipment under controlled conditions.
Key topics and technical requirements
- Scope: Specifies the test procedure to measure CO2 concentration in the inhalation air (dead space) of respiratory protective devices.
- Test principle: A breathing machine supplies a defined CO2 concentration to a Sheffield dummy head/torso fitted with the device; inhaled samples are analysed to assess dead-space CO2 (an indicator of CO2 accumulation).
- Typical test arrangement:
- Sheffield head/torso with concentric tubing and central CO2 sampling tube.
- Breathing machine with solenoid valves; solenoid action must seal cleanly and avoid timing overlap.
- Auxiliary lung to sample a fixed fraction of the inhalation stroke in phase with the breathing machine.
- CO2 analyser, flowmeter, compensator bag and CO2 absorber to control circuit conditions.
- Auxiliary fan (when applicable) delivering 0.5 m/s at 50 mm in front of the device inlet to prevent rebreathing of exhaled air.
- Example settings: 25 cycles/min and 2.0 L/stroke; auxiliary lung sample = 100 ml (5% of inhalation stroke); CO2 feed ≈ 2.5 L/min to produce 5% CO2 in exhaled air.
- Environmental and equipment constraints:
- Ambient test conditions: 16 °C to 32 °C, 20% to 80% RH.
- Total dead space of the test gas path (excluding breathing machine) ≤ 2000 ml.
- Ambient CO2 measured 50 mm in front of inlet must be < 0.1% (or supply air CO2 < 0.1% for independent-air devices).
- Prerequisites: The applicable device standard must specify sampling numbers, preconditioning, facepiece sizes, sealing method, whether the device is tested complete or as a facepiece, air‑supply settings, direction of supplementary airflow and pass/fail criteria.
- Annexes:
- Annex A: normative fitting procedure for neck-sealing hoods (collar and pressure control).
- Annex B: informative guidance on measurement uncertainty.
- Annex ZA: relationship to EU Directive requirements.
Applications and who uses it
- Manufacturers of respirators and hoods - to evaluate and optimize dead-space design and demonstrate product performance.
- Testing and calibration laboratories - for standardized CO2 measurement during type testing and certification.
- Conformity assessors and certification bodies - to verify compliance with device-specific standards and EU directives.
- Occupational health and safety engineers - to interpret CO2 accumulation risk in PPE selection and workplace PPE policies.

Breathing air containing a defined concentration of carbon dioxide is supplied at aspecified rate from a breathing machine to a dummy head/torso. The inhaled air is analysed for carbon dioxidecontent.The carbon dioxide level measured gives an assessment of the "dead space" of the facepiece rather than a "reallife" measurement of the level of carbon dioxide in the inhaled air.5.2 Test equipment5.2.1 GeneralA typical test arrangement using a single cylinder breathing machine is shown in Figure 1.The total dead space of the gas path of the test installation, excluding the volume of the breathing machine, shallnot exceed 2000 ml.The test shall be carried out at ambient conditions.5.2.2 Breathing machineA breathing machine and associated equipment with solenoid valves controlled by the breathing machine. In orderto avoid errors in the measurement of carbon dioxide in the inhaled air, it is important that the solenoid valves makea good seal on closing and that the timing of their action allows no overlap to occur.5.2.3 Carbon dioxide sampling arrangementA sample of the inhaled air is taken by an auxiliary lung driven by the breathing machine and in phase with it. It isset to inhale a known sample volume (a chosen percentage of the inhalation volume of the breathing machine)during the inhalation stroke of the breathing machine. This apparent "loss" in inhalation volume of the breathingmachine is compensated for by the volume of carbon dioxide fed via the flowmeter into the breathing machine onits inhalation stroke. It is therefore important that these two volumes are equal.The exhaled air is continuously monitored for carbon dioxide content at a flow determined by the analyser. Thesample point is immediately before the solenoid valve in the exhalation circuit. To maintain equilibrium the sampleis returned to the circuit upstream of the sample point.The carb
