This, and the other two questions you have posted a few minutes apart, would indicate that either you are being asked to perform tasks for which you are wholly unqualified for (by virtue of you having to ask), or you are a student attempting to get help with homework. Both situations are in violation of forum rules I think, but I am not a moderator, so we'll see if they think so as well.
In the ensuing time before they lock or delete these threads, I will say that the questions you are asking are the type of thing usually described in testing or acceptance standards applicable to your part of the world. Because of previous associations, my experience with Saudi electrical standards is that they are either still using British Standards, or have based their own standards on them.
