Viivakoe

Viivakoe is a Finnish term formed from viiva (line) and koe (test). There is no single, universally defined concept called viivakoe in Finnish; instead the expression is used in various specialized domains to denote a test procedure that involves lines, edges, or line-based patterns. The precise meaning depends on the industry and context.

In metrology and manufacturing, a viivakoe may refer to a line-based inspection used to assess straightness, parallelism, or alignment. A measurement line on a workpiece or tool is checked against a reference baseline to ensure tolerances are met.

In printing, graphic production, or quality control, the term may refer to a test pattern comprised of lines used to evaluate line reproduction, sharpness, resolution, or printer alignment.

In surveying, civil engineering, and construction, a line-based test might involve verifying the accuracy and orientation of baselines or alignments along a designated line.

Etymology and usage: The word is a compound commonly found in technical manuals and industry documents. It is not a widely standardized term outside those specific contexts, and its exact interpretation is typically defined within a given project or standard.
