年限（年単位で定めた期間・耐用年数）

Common in legal, administrative, and technical contexts. Key collocations: 使用年限 (service lifespan), 工作年限 (years of service), 建筑年限 (building lifespan), 保质年限 (shelf life in years). Differs from 期限 (deadline/term), which can refer to any time unit — 年限 always implies a count of years.
