ISO 11119-4:2016 标准是可充装复合气瓶的设计、构造和测试要求的国际标准之一。该标准规定了直径不超过 450 mm，容积不超过 150 L 的全包覆纤维增强复合材料气瓶的要求。这些气瓶通常用于贮存压缩气体，如氧气、氮气、氢气、天然气等。

该标准要求气瓶必须符合以下要求：

1. 气瓶必须由纤维增强复合材料制成，以确保其轻量化和高强度。

2. 气瓶必须具有负荷共享焊接金属衬里，以提高其耐用性和安全性。

3. 气瓶必须经过一系列的测试，包括气密性测试、爆破测试、冲击测试、热循环测试等，以确保其符合国际标准的要求。

4. 气瓶必须标有相关的标识和警示标志，以提醒用户注意安全使用。

ISO 11119-4:2016 标准的实施可以提高可充装复合气瓶的安全性和可靠性，保障用户的生命财产安全。
