IPX 防水等级对照表：IPX6、IPX7、IPX8

IPX 是国际电工委员会 IEC 60529 标准中的防水防护等级代号，数字越大防护越强。采购拉链时最常遇到 IPX6 / IPX7 / IPX8：IPX6 防强力喷水，IPX7 短时浸水，IPX8 持续浸水。

IPX is the water-protection code in IEC 60529. The higher the number, the stronger the protection. When buying zippers you will most often see IPX6 / IPX7 / IPX8: IPX6 resists powerful jets, IPX7 handles temporary immersion, IPX8 allows continuous immersion.

注意事项

Important notes

IPX 只表示进水防护等级，不直接等于“气密 / 保压”；气密还需看密封压力测试（如 60kPa）；
IPX covers water ingress only — it does not equal airtightness or pressure retention; for that, check sealing-pressure tests such as 60kPa.
同一产品可通过多个等级测试，以厂家测试报告为准；
A product can pass multiple ratings; rely on the manufacturer's test report.
采购时要求厂家提供对应等级的第三方或出厂检测报告。
Ask suppliers for third-party or factory test reports for the rating you need.

YILON：提供 IPX6-IPX8 全等级测试；气密拉链额外提供 60kPa 密封压力测试，出厂附检测报告。
