Visual testing requires acute precision. ISO 17637 places strict demands on the personnel executing the inspection to eliminate human error. Certification Standards
Standardization ensures that inspections are repeatable. The standard dictates that for direct visual inspection (using the naked eye or a magnifying glass):
If you’d like, I can:
The standard allows the use of mirrors, boroscopes, fiber optics, or magnifying glasses (typically up to 2x to 5x magnification) to inspect areas with restricted physical access. iso 17637 pdf
The inspector must have adequate illumination to see the weld clearly.
ISO 17637 outlines how to perform the visual inspection, but it does not specify whether a weld passes or fails. To determine acceptance, inspectors use ISO 17637 in tandem with .
Identity and signature of the certified inspector. Implementing ISO 17637 in Quality Management Systems Visual testing requires acute precision
Just tell me which one you need:
For weld repairs, the standard covers:
Assessing surface roughness, spatter accumulation, and tool marks. Critical Inspection Conditions The standard dictates that for direct visual inspection
“Photocopy everything,” Maya said. “And I mean everything — lighting, viewing aids, weld preparation acceptance.”
ISO 17637:2016 standard provides the official framework for the non-destructive visual testing
Therefore, an inspector must pair the ISO 17637 PDF with a relevant acceptance standard to perform a complete inspection.

The primary objective of ISO 17637 is to identify surface imperfections (non-conformities) in the weld. Common defects found during visual testing include:
