前言

本文件按照GB/T1.1—2020《標準化工作導則第1部分：標準化文件的結構和起草規則》的規

定起草。

本文件修改采用ISO11963:2019《塑料聚碳酸酯板材規格、尺寸和性能要求》。

本文件與ISO11963:2019相比，在結構上有較多調整。兩個文件之間的結構編號變化對照一覽表見

附錄A。

本文件與ISO11963:2019的技術差異及其原因如下：

—更改了范圍的適用界限（見第1章），以適應國內聚碳酸酯板材行業的實際情況；

—增加了聚碳酸酯板材的定義（見第3章），以明確本文件適用的產品類型；

—刪除了板材擠出的材料類型（見第4章），以適應國內聚碳酸酯板材行業的實際情況；

—增加了板材對耐候防護層與耐候性的要求（見5.1、5.6），更改了板材外觀的要求（見5.2）、垂直

度的要求（見5.2）、一般性能的要求（見5.5），以適應國內聚碳酸酯板材行業的實際情況；

—用規范性引用的GB/T2918替換了ISO291（見6.1.2）、GB/T39812—2021替換了

ISO2818（見6.1.3）、GB/T1040.2替換了ISO527?2（見6.4）、ISO179?1:2023替換了

ISO179?1:2010、ISO8256:2023替換了ISO8256:2004（見6.5）、ISO306:2022替換了

ISO306:2013（見6.6）、GB/T1634.2—2019替換了ISO75?2:2004（見6.7）、

GB/T2410—2008替換了ISO13468?1（見6.9）、GB/T16422.1替換了ISO4892?1、

GB/T16422.2替換了ISO4892?2（見6.10.1）、GB/T3681.1替換了ISO877?1、

GB/T3681.2替換了ISO877?2（見6.10.2），以適應我國的技術條件，提高可操作性；

—更改了試樣狀態調節的時間（見6.1.2）、試樣制備的要求（見6.1.3），更改了外觀和顏色的

試驗要求（見6.2）、尺寸的試驗要求（見6.3）、拉伸性能的試驗要求（見6.4）、透光率的試

驗要求（見6.9）和人工氣候老化的試驗要求（6.10.1），增加了防火性能的試驗要求（見

6.11），以適應國內聚碳酸酯板材行業的實際情況；

—更改了檢驗規則的要求（見第7章），以符合我國標準編寫習慣；

—增加了“標志、包裝、運輸、貯存”的內容（見第8章），以符合我國標準編寫習慣；

—將其他性能要求更改為資料性附錄B，因其內容本身未包含指定檢驗項目和性能要求，僅為供

需雙方提供一定參考；

—刪除了ISO11963:2019中6.4.1的拉伸性能試樣要求，以提高可操作性；

—刪除了ISO11963:2019中第8章，以符合我國相關法律法規。

本文件做了下列編輯性改動：

—為與現有標準協調，將標準名稱更改為《塑料制品聚碳酸酯板材》；

—4.2中增加了注；

—6.5中增加了注。
