What is the meaning of 範囲等の申請範囲 in this sentence?


I'm having a hard time trying to get the meaning of 範囲等の申請範囲 in the following
sentence. Context: instruction on how to fill in a form to apply for quality
evaluation of wood materials.

> 青色で囲っている部分は、各材料のバリ エーション、数値の公差、範囲等の申請範囲を示す部分です。

Why the repetition of 範囲? What is the value of 等? Here is my bad attempt:

> The section circled in blue is where the write each material variation,
> numerical value of tolerance and _requested range of scope_.

Also, the meaning of 申請 it is not so clear to me. Could it refer to someone
that requested the quality evaluation (for example a company)? Thank you for
your help!




> 青色で囲っている部分は、＜｛各材料の①バリエーション、②数値の公差、③範囲、④等("etc")｝の｛申請範囲｝＞を示す部分です。

The first 範囲 refers to the tolerable _physical_ range of measurement values
according to the spec. I'm not sure how バリエーション, 公差 and this 範囲 differ from
the professional point of view (they all seems to refer to so-called
[engineering tolerance](https://en.wikipedia.org/wiki/Engineering_tolerance)).
Maybe they wanted to make it very clear by saying similar words three times.

The second 範囲 in 申請範囲 refers to the extent to which this application form
covers. The literal translation of 申請範囲 would be something like "application
_scope_ ". Actually I don't see any good reason why they needed to use 範囲
here. Using the same word twice with two different meanings is certainly
annoying, and I feel they could have said 申請内容 or 申請項目 instead without
changing the meaning.




I think there are two separate ranges/scopes (範囲) here - first one belongs to
a noun 数値 and is a part of enumeration: tolerance, range, etc. - therefore the
等 right after the first occurrence of 範囲. Basically this part lists
objects/concepts being measured/evaluated.

The second occurrence is a separate concept： 申請範囲 - it is a set of
requirements that should be fulfilled (E.g. in a form of acceptable ranges).

So you seem to have 数値の範囲 and 申請範囲, meaning there is no repetition, at least
not of a semantical type.
