EN 10204 3.1 与 3.2 质保书:差别在谁签发

3.1 质保书由制造厂质量部门签发并声明符合订单要求;3.2 质保书由制造厂以外、且与制造厂无利益关系的独立检验机构或授权代表签发并见证试验。
EN 10204 规定金属材料检验文件类型。 3.1:由制造厂质量部门授权的检验代表签发,声明产品符合订单要求,并附熔炼分析与力学性能等检验结果;文件在制造厂体系内产生。 3.2:由制造厂以外、且与制造厂无利益关系的独立检验机构或授权代表签发,通常要求第三方见证取样与试验,文件由第三方签署。 实务差异:3.1 成本低、交付快,适用于一般工业用途;3.2 的公信力与可追溯性更强,常用于压力容器、海洋工程、核电与业主指定项目。 采购时应在合同中明确要求类型、检验项目、见证方式与文件语言,避免到货后因文件等级不符影响验收。
