散漫说,线束相关试验分DV和PV两块,即设计验证和产品验证。本文为沃尔沃线束PV测试内容,供大家参考。
PV全称为Product Verification,即产品验证,指从供应商的量产生产线上做出来的零件去做的相关试验验证。PV之后的零件再完成PPAP审核,就具备了量产供货资格了。Volvo汽车线束PV试验内容列表如下:文章源自线束工程师之家-https://www.suncve.com/wiring-harness-pv-test-specification-for-volvo-project/

一.Compatibility test/兼容性测试
1.目的文章源自线束工程师之家-https://www.suncve.com/wiring-harness-pv-test-specification-for-volvo-project/
主要是验证线束上的各物料不会以负面的方式相互影响,且物料仍然能实现其基本特性和重要特性。文章源自线束工程师之家-https://www.suncve.com/wiring-harness-pv-test-specification-for-volvo-project/
2.评估方法文章源自线束工程师之家-https://www.suncve.com/wiring-harness-pv-test-specification-for-volvo-project/
在特定温度下进行1000小时老化,然后拆除被测试线束表面的覆盖物。主要评估步骤如下:目视检查线束部分的变化 (包括颜色变化,柔性变化和其他物理变化),若目视评判结果差,将进一步完成折弯缠绕测试和30分钟耐高压测试。(具体可看,可私底下跟小编要这些标准)文章源自线束工程师之家-https://www.suncve.com/wiring-harness-pv-test-specification-for-volvo-project/

3.涉及到PV试验的变更文章源自线束工程师之家-https://www.suncve.com/wiring-harness-pv-test-specification-for-volvo-project/
线束表面覆盖物的变更与新增l 线束电线的变更(材质/线型),颜色/长度变化可不在此变更中文章源自线束工程师之家-https://www.suncve.com/wiring-harness-pv-test-specification-for-volvo-project/
4.样件准备要求文章源自线束工程师之家-https://www.suncve.com/wiring-harness-pv-test-specification-for-volvo-project/
每个线束成品准备一根高配成品线束,提供老化温度等级。二.Water proof of grommet/护套的防水测试1.目的验证水流是否进入而引起功能缺陷。2.评估方法根据ISO_20653:2013标准对图纸上有防水要求(IP等级)的护套进行测试文章源自线束工程师之家-https://www.suncve.com/wiring-harness-pv-test-specification-for-volvo-project/
3 .涉及到PV试验的变更l 护套的新增以及变更l 护套防水等级的变更(IP等级的变更)l 工艺的变更(缠带、覆盖物等)
