Common Questions About Our Services

Get quick answers about J&L Dimensional’s capabilities, certifications, and the industries we work with every day.

Inspection capability depends on part geometry, feature size, measurement method, and required uncertainty. Using structured light scanning, J&L can verify features with tolerances as small as 5–6 microns. Our coordinate measuring machines (CMMs) can verify dimensions with accuracies supporting tolerances of approximately ±0.0005 inches. For specific applications, our team can review your drawing requirements and recommend the most appropriate inspection method.

J&L typically provides layout inspection results using AS9102 Form 3 reporting. We can also accommodate customer-specific reporting formats when requirements are provided in advance. Documentation supporting our ISO/IEC 17025 accredited laboratory is available upon request and can also be accessed through our website.
