IP与IK的分级

发布日期:2018-11-09

电气密封箱的防水、防尘防护程度为 IP 等级,其表达方式是下面所列的 2 个数字编码组合,健龙 根据 IEC529 ?#26696;?#26032;的 EN60529 4:1992 进行了 IP 测试。

两个测试方法中后者要求要对密封箱单独进行 IP66 和 IP67 的测试。其结果有时存在像 IP66/IP67 的两个 IP 标法,这表明对密封箱单独进行了两个等级的测试。

新的电气密封箱?#20998;?#26631;准 EN50298:98 规定还要包括 IK 抗冲击测试。这里所提供的测试资料是根据 EN50102 进行的, 建龙正在根据新规则 EN50298:98
