Why Old Test Data May Not Be Enough Anymore

Written by Professional Testing Laboratory Team | Jan 16, 2026 5:45:00 PM

Why Test Data Becomes Outdated

1. Material or Supplier Changes

Even small changes in raw materials, suppliers, or formulations can significantly affect performance.

2. Manufacturing Process Adjustments

Equipment upgrades, process efficiencies, or cost-saving measures can unintentionally alter product behavior.

3. Updated ASTM or ISO Standards

Standards evolve. Older test reports may not align with current requirements or expectations.

4. New Applications or Markets

Products used in new environments or applications may require additional validation.

5. Increased Buyer and Retailer Scrutiny

Many buyers now require recent third-party test reports as part of approval processes.

The Risks of Relying on Old Data

  • Product failures in real-world use

  • Noncompliance with updated standards

  • Rejected submittals or lost bids

  • Increased liability exposure

Refreshing test data protects both your product and your reputation.

When to Consider Retesting

  • At the start of a new year

  • After material or process changes

  • When entering new markets

  • When standards are revised

  • When buyers request updated documentation
