Overview
IEC 61300-2-17:2010 is an international standard developed by the International Electrotechnical Commission (IEC) that specifies basic test and measurement procedures for fibre optic interconnecting devices and passive components. This particular part, Part 2-17, focuses on tests conducted under cold environmental conditions. It establishes a procedure aimed at determining the suitability of fibre optic devices to withstand extended low temperature conditions, which may arise during use, storage, or transport.
The test procedure outlined in IEC 61300-2-17:2010 does not cover the device's operational capability during temperature fluctuations-this is addressed in a related standard, IEC 61300-2-22. The standard has been revised from its previous edition to improve test accuracy, including narrowing the allowed temperature deviation during testing from ±3 °C to ±2 °C and reconsidering test details and procedures.
Key Topics
-
Scope and Purpose
The standard is designed to assess fibre optic components’ ability to endure prolonged exposure to cold temperatures, ensuring reliability and robustness in real-world scenarios involving cold storage or harsh environments.
-
Test Environment and Apparatus
Testing is conducted in an environmental chamber compliant with IEC 60068-2-1 test Ab. The chamber must maintain the specified temperature with a deviation of no more than ±2 °C. It should also accommodate the device under test (DUT) and allow for optical or mechanical measurements if required.
-
Test Procedure Steps
- Preconditioning the device under standard atmospheric conditions for at least 2 hours.
- Conducting initial measurements and visual inspections as specified in relevant documentation.
- Lowering the chamber temperature to the target value at a controlled rate not exceeding 1 °C/min.
- Maintaining the DUT at the cold temperature for 96 hours.
- Raising the temperature back to ambient at the same rate and allowing recovery time.
- Performing final measurements and visual examinations to detect any permanent damage.
-
Severity Parameters
The test severity involves temperature targets commonly at -40 °C, -25 °C, or -10 °C, each maintained for 96 hours, with a maximum temperature deviation of ±2 °C.
-
Reporting Requirements
The standard requires specifying various details including manual or automatic tests, initial and final performance requirements, permissible deviations, and pass/fail criteria according to relevant product specifications.
Applications
IEC 61300-2-17:2010 is essential for manufacturers and quality assurance teams involved in the design, production, and validation of fibre optic interconnecting devices and passive components. It ensures that devices can tolerate conditions associated with cold climates or cold-chain logistics without degradation or failure.
Common application areas include:
-
Telecommunications Equipment
Ensuring optical connections in outdoor or unheated environments remain reliable through cold seasons.
-
Data Centers and Networking Infrastructure
Qualifying components used in unconditioned spaces or during winter transportation.
-
Military and Aerospace
Verifying equipment performance and durability under extreme temperature conditions.
-
Industrial Automation
Testing components used in low-temperature operational environments such as refrigerated warehouses or cold climates.
By conforming to this standard, companies reinforce their product reliability and comply with international testing best practices.
