tarkastusjakson

Tarkastusjakso is a contractual term used in Finland to describe a defined period after delivery or implementation during which the recipient may inspect goods, services, or software to verify conformity with the agreed requirements. It is not a separate law, but a provision negotiated between the parties that governs acceptance and verification activities.

The purpose of a tarkastusjakso is to allow thorough verification of quality, functionality, and performance beyond what may be evident at the moment of delivery. During this period, the buyer or user can identify defects, deviations from specifications, or performance shortfalls that should be addressed by the supplier. The scope typically includes testing, measurement, or inspection activities and is defined by criteria or acceptance tests in the contract.

The duration and procedures of a tarkastusjakso are contract-specific. The period should be long enough to perform meaningful checks but clearly bounded to avoid prolonged uncertainty. The contract often outlines how defects must be reported, whom to notify, and what constitutes acceptance or rejection. If issues are found, remedies may include repair, replacement, price adjustment, renegotiation, or, in some cases, contract termination.

Impact and practical considerations vary by industry. Tarkastusjakso is commonly used in procurement, construction, and the delivery of complex machinery or software, where commissioning and performance verification are important. When drafting or negotiating a tarkastusjakso, parties should define explicit acceptance criteria, reporting procedures, remedies, and how the period interacts with warranty or defect liability to ensure predictable rights and obligations.
