IEC 62899-505:2020(E) specifies mechanical and thermal test methods for the determination of the reliability characteristics of a printed flexible gas sensor, which is operated at relatively low temperature and is composed of a flexible substrate, electrode, and gas sensing layer. The examples of target gas include in-door air pollutants, combustion gas from a fire situation, and industrial flue gas.

Overview

IEC 62899-505:2020 is an international standard that defines mechanical and thermal test methods for assessing the reliability of printed flexible gas sensors. It targets sensors built by printed-electronics techniques (flexible substrate, printed electrode and sensing layer) that operate at relatively low temperatures and are used to detect gases such as indoor air pollutants, combustion products (fire scenarios) and industrial flue gases. The standard helps unify test procedures for qualification of flexible and wearable gas-sensing products.

Key topics and requirements

Scope of tests

Mechanical durability: bending, torsion and stretching tests tailored to the sensor’s flexibility and intended application.
Thermal durability: temperature cycling (upper/lower temperature extremes, conditioning, and defined severities) to evaluate thermal stress effects on sensing performance.

Gas sensing performance measurement

Performance is measured before/after and at defined points during tests; results are reported as a consistency percentage between the actual test-gas concentration and the sensor reading.
Exposure sequence: clean air followed by test gas after stabilization; measurements taken at the end of each exposure.

Controlled environmental conditions

Temperature controlled to ±2 °C during tests.
Relative humidity controlled to ±5 % RH unless otherwise specified.
Atmospheric pressure range specified: 86 kPa to 106 kPa.
Test gas delivered as a known mixture with clean air (N2/O2 mix); volume fraction uncertainty of the test gas component to be within ±2 % of nominal.

Reporting

Test method descriptions, tolerances, conditioning procedures, test cycles and severities must be documented; results reported in accordance with the standard’s clauses.

Applications and who uses it

Product manufacturers of printed and wearable gas sensors seeking consistent qualification procedures for device reliability.

R&D teams developing flexible sensor substrates, printed electrodes, and sensing inks who need to validate mechanical and thermal robustness.

Independent test laboratories and QA teams performing acceptance, batch or type testing.

PPE and wearable-system integrators (e.g., firefighter garments, industrial workwear) requiring validated gas-sensing performance under mechanical deformation and thermal stress.

Certification and regulatory bodies seeking harmonized test methods for device claims.
