ISO 21809-1:2018标准适用于埋地或水下管道的外部涂层,主要包括聚烯烃涂层,如3层PE和3层PP。这些涂层主要用于保护管道免受腐蚀和机械损伤,以确保管道的长期使用寿命和安全性。

该标准规定了涂层的要求,包括涂层的厚度、附着力、耐磨性、耐化学性、耐水分解性等。此外,标准还规定了试验方法,如附着力测试、耐化学性测试、耐水分解性测试等,以确保涂层符合要求。

在检验和验收方面,标准规定了涂层的外观、厚度、附着力、耐磨性、耐化学性、耐水分解性等指标的检验方法和验收标准。这些指标的检验和验收是确保涂层质量的重要环节。

总之,ISO 21809-1:2018标准是保障埋地或水下管道长期使用寿命和安全性的重要标准,对于涂层制造商、管道运营商和监管机构都具有重要意义。
