We have updated criterion 4.2, acoustic noise. Testing can now be carried out according to ECMA-74, 20th edition.
ECMA-74, 20th edition includes changes to the operating modes during testing. The following modes are included:
- Web browsing mode
- Office productivity
- Media content creation
- Power user & gaming
These modes may be used instead of the “HDD”, “CPU”, and “ODD” modes, which are stated in the old edition.
ECMA-74, 20th edition will also be used for testing acoustic noise levels in TCO Certified, generation 10. If you have questions, please contact us on certification@tcodevelopment.com.
