例句1：

API 686 is written such that it can be used as a contractual document between an owner company and an engineering and construction (E&C) contractor.

such that引导的结果状语从句为正式语体，同时兼有方式状语的意味。such that= in such a way that = in a way that has the result that。所以你的句子用in such a way that去改写such that就很好理解了。

API 686 is written in such a way that it can be used as a contractual document between an owner company and an engineering and construction (E&C) contractor.

API 686的书写格式使其可以用作A公司和B公司之间的合同文件。

下面是夸克《英语语法大全》对such that解释以及例句：

Such that (formal) combines result with manner:
The two halves of the human brain behave independently, such that
each halfcan be taught opposite solutions to simple problems. ['. . . in a
way that has the result that. . .']

例句2：

The trial lifting shall be such that the crane hook shall lift slowly the equipment to a height of 200mm to 300mm and keep the stabilized equipment at least 5 min.

这个句子中such作主句表语，that引导结果状语从句。such仍然可以理解为in such a way.

字面意思为：试吊应该是如下的方式，使得吊钩...

按照汉语表达习惯翻译为：试吊时，吊钩应将设备缓慢吊至20-30公分高度并保持设备稳定至少5秒钟。
