To standardize the European telecommunications environmental testing, the European Telecommunications Standards Institute (ETSI) was established in 1988. The Technical Committee Environmental Engineering (EE) of ETSI has set up three Working Groups (WG):EE1
Is responsible for environmental conditions and environmental tests for telecommunications equipment, and the standard produced is: ETS/EN 300 019, which contains two parts.
Part 1: standardize different climatic conditions and environmental classes.
Part 2: specifies the recommended test conditions and test methods for the different environmental classes, test procedures mainly based on IEC/EN 60068 Part 2 and IEC 60721.
Deals with power supply issues, such as earthing, power distribution, bonding techniques and interface issues.
In regarding to power supply, mechanical standards on racks mount or sub-racks follows ETS 300 119.
EE-TMG (Thermal Management Group)
Reviews and updates the ETS 300 119 series standards, the thermal management for equipment and facilities in specific.
ETSI/EE successively promulgated two series of environmental conditions and test standards of communication products as listed below. The first series is ETSI EN 300 019 Part1, which gives descriptions of environmental categories and severity levels; the second series is ETSI EN 300 019 Part2, which gives conditions and procedural guidelines of environmental tests;

ETSI 300 753 Acoustic noise emitted by telecommunications equipment
Our Reliability Division researched the possibilities of using these standards and has set up qualified equipment and techniques with a complete set of test services. However, the practicality is that ETSI is used for European storage, shipping and transportation environments. Therefore, temperature conditions are low temperature testing. And since Europe is a highly developed area, the roads are smoother and hence, vibration testing is lower. When applying ETSI standards, there should be attention on the practicality of these standards and how to adjust them to meet your needs.
