eftersyn

Eftersyn is a Danish term meaning inspection, re-inspection, or post-check. It denotes a formal process where a qualified person or authority examines a set of conditions to verify safety, compliance, or quality after a defined period, event, or use. The word combines efter (after) with syn (seeing or inspection), and is used across various professional contexts.

In Denmark the most common usage concerns periodisk køretøjs eftersyn, or periodic vehicle inspection. This is a state-regulated process where vehicles are checked by approved inspection centers to ensure safety and emissions standards. The inspection covers components such as brakes, steering, lights, tires, and emissions equipment, and may also review documentation and vehicle modifications. Depending on the outcome, the vehicle may receive an approved certificate or be required to undertake corrective work and return for a reinspection. Fees and exact intervals are determined by national rules and may vary by vehicle type, age, and model. The inspection system aims to improve road safety and environmental performance and is administered by a government authority in cooperation with authorized private testing facilities.

Eftersyn is also used in other contexts to describe follow-up checks after work is completed, repairs, or alterations. In housing, industry, and construction, eftersyn may refer to post-service evaluations, quality control checks, or compliance verifications conducted to confirm that outcomes meet agreed standards. In real estate and procurement, a post-transaction eftersyn can be used to verify condition and function before final acceptance.
