Device Master Record – DMR

Information & Training. | Medical Device Validation, Regulation, …

The requirement for a Device Master Record is outlined in the FDA’s Quality System Regulations (QSR’s), per section 21 CFR 820.3(j).

The FDA define general requirements for records, which include their accessibility, location of storage, confidentiality expectations and retention times.

Specifically, the FDA identify the necessity for creating and maintaining a Device History File, Quality System Records, Complaint Files and a Device Master Record.


Device Master Record – DMR

The DMR needs to be developed for each “type” of medical device and will include the following information as a minimum:


The approved, released specifications for the finished device. This includes details of the all components, all software, any applicable formulation and composition.

Specifications for the production processes utilized, which includes methods of production, details on process, measurement and test equipment, operating and test procedures, and environmental specifications.

Quality Assurance test, measurement and operating procedures, quality assurance and quality control acceptance criteria, also details on all quality related test and measurement equipment.

Specifications and operating procedures on all device packaging.

Specifications, procedures and examples of all labelling.

Operating procedures and methods applicable to product installation, maintenance and service.
