This document outlines design requirements and testing standards for small wind turbines according to international standards IEC 61400-2:2006 and CNS 15176-2-1. It discusses design load testing, safety systems testing, performance measurements, material testing, power and acoustic performance testing, full scale wind tunnel testing, vibration testing, design reviews, and certification requirements. The standards provide guidelines for blade loading, structural testing, and the development process.

2. Design requirements
for small wind
turbines
The turbine is
designed in
accordance with
this international
standard as a
minimum
requirement
The standard covers:
design load, safety
systems, structural
testing,
performance
measurements
IEC 61400-2: 2006

3. Based on IEC 61400-2:
2006
Some changes to
make the standard
more relevant for
small vertical axis
wind turbines
Hi-VAWT are on the
committee for the
development of the
standard advising
on VAWTs.
