processed and meet the standard requirements prior to primer painting.

第一句话,还可以了,就是above用的,我个人觉得不太恰当：
Components mentioned above shall be processed so as to meet the standard requirements prior to primer painting.
还有就是,and meet,您用的是,我觉得这个主语不同,您不能说是以上构件满足要求,而是经过处理以后的构件的表面,满足涂装的要求,这里我用了 so as to.
The surface of steel plate cleaned with shot blasting shall achieve Sa 2.5 (Near White ).
用了一个过去分词作定语；近白级,near white就可以了.

above components asks to paint before spraying in the bottom and must do it and reach the standard ask. 第二局，shall achieve 换为 should reach

说得不好，分太少，很难回答

The above components must be treated before spraying primer and meet required standards.
The steel plate shot blasting should meet the level of Sa 2.5.

[务必] 翻译为must 比shall 更贴切。
[符合规范要求] 用 comply with 更佳。
抛丸清理 - shot blast cleaning
近白级 - 不能用near ,可以用 nearly 或 close to

All those mentioned components should be processed(这里的处理是不是应该有一个具体的动作呢？如果有的话，就不要用process了。) and meet the standardized requirement before primer spraying.
steel impact cleaning level should reach Sa 2.5 (close to white)

用我修改的吧。

因为有“请务必”，所以还是用"Please make sure"比较到位。
钢板抛丸清理等级应达到Sa2. 5（近白级）
The grade of stell shot blasting cleaning should achieve Sa2.5 (near the grade of white blast)
等级一词我就翻译成"the grade"了。不了解你的行业里有否别的说法。可讨论。

已经不错!建议修饰一点:

1. The above components shall be processed according to the standard requirements prior to primer (paint) spray.

2. Steel shot blasting cleaning shall achieve Sa2. 5（near/close to white blast scale). 

底漆喷涂=primer底 paint漆 spray名词; 不是"painting".

scale=比例;尺度

according=根据; meet; comply with.

两个主要问题：1、中文“以上”的意思没有正确表达。 2、应用被动语态表达第二句。
所以整个应该改为：
1、The above mentioned components shall be
treated to comply with the standard requirements before primer painting coat processing.
2、...

懂工程的人不懂英语，懂英语的人不懂工程，实乃中国工程界的一大悲哀！
