IS/IEC 60034 : Part 5 : 2020 Rotating Electrical Machines - Part 5 Degrees of Protection Provided by the Integral Design of Rotating Electrical Machines (IP Code) - Classification
NATIONAL FOREWORD
This Indian Standard (Part 5) (Third Revision) which is identical to IEC 60034-5 : 2020 'Rotating electrical machines - Part 5: Degrees of protection provided by the integral design of rotating electrical machines (IP code) - Classification' Issued by the International Electrotechnical Commission (IEC) was adopted by the Bureau of Indian Standards on the recommendation of the Rotating Machinery Sectional Committee and approval of the Electrotechnical Division Council.
This standard was first published in 1985 and subsequently revised in 2000. This revision has been brought out to align the standard with the latest version of IEC 60034-5 : 2020.
On the recommendation of the Rotating Machinery Sectional Committee single numbering has been adopted for IEC 60034 series to avoid confusion in use and implementation as experienced by industry, lab and other stakeholders.
This standard is published in various parts. Other parts in this series are:
Part 8 Terminal markings and direction of rotation
Part 27 Winding insulation of rotating electrical machines
The text of the IEC standard has been approved as suitable for publication as an Indian Standard without deviations. Certain conventions are, however, not identical to those used in Indian Standards. Attention is particularly drawn to the following:
a) Wherever the words 'International Standard' appears referring to this standard, they should be read as 'Indian Standard'; and
b) Comma (,) has been used as a decimal marker, while in Indian Standards the current practice is to use a point (.) as the decimal marker.
