Bibliography

IEC 60695-6-2:2011 provides a summary of the test methods that are used in the assessment of smoke obscuration. It presents a brief summary of static and dynamic test methods in common use, either as international standards or national or industry standards. It includes special observations on their relevance to electrotechnical products and their materials and to fire scenarios, and it gives recommendations on their use. This standard cancels and replaces IEC/TS 60695-6-2 published in 2005. This first edition constitutes a technical revision. The main changes with respect to the previous edition are listed below:
- this publication has been re-designated as an International Standard;
- updated normative references;
- updated terms and definitions; new test method Clause 7.3.2;
- numerous editorial changes of a technical nature throughout the publication.
It has the status of a horizontal standard in accordance with IEC Guide 104and ISO/IEC Guide 51.

This publication is to be read in conjunction with IEC 60695-6-1:2005.
