Katsetatud

Katsetatud is a word in Estonian that functions as a past passive participle of the verb katsetama, meaning “to test.” It is used to describe something that has undergone testing or experimental evaluation. In translation, katsetatud can be rendered as “tested,” “tried,” or “evaluated.”

Etymology and form: The term is formed from the noun katse (test) plus the verbal stem katset-, then the past passive participle suffix -tud, yielding katsetatud. As a participle adjective, it agrees with the noun it modifies in number and case, for example katsetatud meetod (tested method) or katsetatud ravim (tested drug).

Usage: Katsetatud is common in technical, scientific, medical, and quality-control contexts, where it denotes that a procedure, method, device, or product has been subjected to formal testing. It can appear in product descriptions, research reports, and regulatory or safety documentation. The word emphasizes the completed status of testing rather than ongoing or planned evaluation.

Related terms: The noun forms katse (test) and katsetus (testing, the process of testing) are related, as is the verb katsetama (to test). Other related adjectives include proovitud (tried/tested) and kontrollitud (controlled, checked), which have distinct nuances.

Examples:

- Katsetatud meetod näitas paremaid tulemusi kui varasem versioon.

- Toode on katsetatud ja heaks kiidetud.

Katsetatud thus conveys that validation or verification work has been carried out, providing a sense of reliability and verified performance.
