Testing in Regulated Environments#
Medical devices, defense electronics, and aerospace systems operate under regulatory frameworks that affect testing requirements. Whether you're pursuing FDA clearance, working with defense contract specifications, or meeting aerospace quality standards, your test infrastructure becomes part of your quality system.
This creates legitimate complexity—but also creates opportunities for vendors to overcomplicate simple solutions. Understanding what regulations actually require helps you build appropriate test infrastructure without unnecessary overhead.
What Regulations Actually Require#
Across regulated industries, testing requirements generally fall into several categories:
Traceability: You need to document what was tested, when, with what equipment, and what results were obtained. Test results must trace back to specific production lots or serial numbers.
Equipment qualification: Test equipment and fixtures must be documented as suitable for their intended purpose. This typically means defined specifications, periodic calibration or verification, and controlled change processes.
Process validation: The test process itself must be documented and demonstrated to consistently detect the defects it's intended to catch.
Record retention: Test records must be maintained for defined periods, typically years to decades depending on product lifecycle and regulatory requirements.
What Regulations Don't Require#
Regulations generally don't mandate:
- Specific vendors: There's no regulatory preference for any fixture vendor. The requirement is documented, controlled equipment—not any particular source.
- Custom engineering: Standard fixtures work for regulated applications when they're properly documented and controlled.
- Excessive complexity: Regulatory requirements are about documentation and control, not fixture sophistication.
The goal is demonstrating that your testing is consistent, controlled, and documented—not that it's expensive or complicated.
Your Specific Challenges#
Medical device teams face FDA quality system requirements (21 CFR Part 820), ISO 13485 certification expectations, and often Design History File (DHF) documentation needs. Test fixtures become controlled equipment requiring qualification, maintenance procedures, and change control.
Defense contractors work with various MIL-STD requirements, contractor quality system specifications, and often requirements for domestic manufacturing. Documentation requirements vary by contract and classification level.
Aerospace companies navigate AS9100 requirements, customer-specific quality specifications, and often stringent reliability expectations. Test equipment qualification and calibration programs are typical requirements.
How FixturFab Addresses These Needs#
Our standard fixtures work for regulated applications when properly documented. Here's what we provide:
Fixture documentation: Mechanical drawings, bill of materials, and assembly documentation suitable for quality system records.
Consistent manufacturing: Standard configurations manufactured repeatedly, supporting process validation and equipment equivalence arguments.
Change control visibility: When we update fixture designs, version changes are documented. You can specify version locks if change control requires it.
Calibration recommendations: Guidance on periodic verification for fixtures in production use.
Standard components: Fixtures built from commercial components with documented specifications, simplifying equipment qualification.
What We Don't Provide#
To set appropriate expectations:
- We don't write your validation protocols or quality documentation. That's your quality system, reflecting your specific requirements and risk analysis.
- We don't certify fixtures for specific regulatory requirements. Certification is your responsibility based on your regulatory strategy.
- We don't maintain regulatory expertise in every jurisdiction or application area. We provide fixtures and documentation; you provide regulatory interpretation.
- We don't offer "FDA-approved fixtures" (that's not how FDA regulation works for this equipment class).
Recommended Approach#
Start with standard fixtures. Configure in Studio, get fixtures in 2-3 weeks, and integrate into your quality system. Standard configurations simplify equipment qualification because they're manufactured consistently.
Document appropriately. Include fixture specifications in your equipment documentation. Define periodic verification procedures appropriate to your risk analysis. Maintain test records per your quality system.
Avoid over-engineering. Regulatory requirements are about control and documentation, not fixture sophistication. A well-documented standard fixture often meets requirements more cleanly than a custom solution with incomplete documentation.
Plan for fixture lifecycle. Test fixtures are equipment that requires maintenance, periodic verification, and eventually replacement. Build this into your quality planning from the start.
Customer Examples#
We work with medical device companies from early development through production deployment. Defense contractors use our fixtures for testing across multiple contract types. Aerospace customers deploy fixtures at CMs and internal production sites.
Contact us to discuss your specific regulatory context. We can share relevant experience and help you evaluate whether standard fixtures meet your documentation and control requirements.
Next Steps#
Configure a fixture in Studio to see specifications and pricing. If you have questions about documentation for your specific regulatory context, contact us to discuss. We'll provide honest guidance on what we can and can't support for your compliance needs.
