（原标题：韩政府决定改变实施60多年的KS认证体系） 据韩国《KBS WORLD》2月4日报道, 韩国政府决定根据当前产业结构，对KS（韩国工业标准）认证制度进行全面调整。KS认证自1961年实 施以来，主要以制造全过程为审查对象，但随着产业分工细化，现行制度已难以适应研发、设计与生产分离的现实需求。为此，产业通商部将推 进制度改革，使KS认证更贴近当下产业生态。 根据新方案，仅负责研发和设计、将生产外包的企业也可申请KS认证。制度完善后，半导体设计专业公司、机器人开发与设计企业等此前难 以取得认证的主体，将被纳入认证范围。政府表示，此举有助于生产设备有限的初创企业加快产品商业化，同时将认证续期周期由现行的3年延长 至4年，以减轻企业的行政和审核负担。 在具体认证方式上，风力发电设备的KS认证也将更具灵活性。今后，塔架等结构性部件规格变更时无需重新进行整机验证即可获得认证。同 时，政府将强化事后监管，与关税厅协作防止不合格KS产品流入市场，并在接到盗用认证举报时立即调查；若企业被查实故意生产不符合标准的 产品，将适用"一次撤销"制度，立即取消其认证资格。 ...
