Did you know a minute particle could skew an entire metallurgical test? Dive deep with OnPointCal—an ISO 17025 accredited calibration laboratory—and uncover why purity in your testing environment isn’t just crucial; it’s non-negotiable.

Meet the Silent Disruptors: Coolant Mists, Dust, and Vibrations

The world of metallurgical testing is susceptible to seemingly inconspicuous culprits:

  1. Coolant Mists: Emerging from machining, these can linger on equipment, hampering precision and functionality.
  2. Dust & Debris: Residues from grinding to milling processes might not be visible, but they can compromise your testing apparatus.
  3. Vibrations: External machinery vibrations, though often overlooked, can significantly impact the accuracy of hardness testers.

The Stakes are High: Why Combat These Adversaries

  • Precision Over Everything: In sectors like aerospace or automotive, even a slight inaccuracy can have far-reaching consequences.
  • Equipment Lifespan: Contaminants shorten the life of your prized metallurgical testers.
  • Economic Efficiency: Precise results lead to optimized operations and reduced wastage.
  • Compliance & Safety: Your commitment to industry standards and safety can hinge on a test’s accuracy.

Building a Bastion: Ensuring a Pristine Testing Space

  1. Physical Barriers: Consider setting up dedicated rooms or partitions to shield testers.
  2. Advanced Air Filtration: Prioritize high-quality air purification systems to trap even the tiniest particulates.
  3. Consistent Cleaning: Implement regular equipment cleaning schedules.
  4. Vibration Shields: Utilize vibration isolators or platforms to negate external disturbances.
  5. Calibration Commitment: OnPointCal is your ally in maintaining top-tier equipment standards.


In the detailed domain of metallurgical testing, every detail matters. Recognizing and rectifying potential pitfalls is essential, and a controlled environment is paramount. Let OnPointCal guide you in achieving precision in every test.
