Comparing Class 10 ISO 4 Cleanrooms with Other Standards

At Secure Data Recovery Services, we always take appropriate precautions to protect our clients’ data. For a number of years, we have invested in state-of-the-art technology, and we were the world’s first data recovery provider to earn a Class 10 ISO 4 Cleanroom certification. Our Cleanroom completely eliminates potentially harmful particles from our work environment, which allows our engineers to safely repair hard drives, RAID arrays, flash drives, solid-state drives and other devices.

Cleanroom classification is an important factor when evaluating data recovery providers. Many companies use Class 100 or ISO 5 standards; we use Class 10 ISO 4 standards in order to guarantee the best possible success rates for our clients. The table below compares different types of Cleanroom classifications according to standards established by US Federal Standard 209E and the International Standards Organization (ISO).

*The number of times that the Cleanroom completely replaces its air from external sources.

**An important factor in controlling Cleanroom cleanliness. A higher velocity allows for more control over contamination.

Secure Data Recovery Services maintains a Class 10 ISO 4 Certified Cleanroom through regular audits and tests. We feel that the strict controls established in Class 10 / ISO 4 standards are much more appropriate for newer devices than Class 100 / ISO 5 standards, particularly in relation to airflow control. Our Cleanroom prevents pockets of contaminated air from affecting your chances of a successful recovery, and we test our Cleanroom regularly to ensure full compliance.

We proudly provide proof of our Cleanroom credentials for the benefit of our clients.Visit our Cleanroom page to view audit documents or call our customer service team at 1-800-388-1266 for more information regarding our cutting-edge data recovery technology.
