COUPON HOLDER FOR CORROSION MEASUREMENT
A non-metallic coupon holder assembly comprising a non-metallic support structure and a plurality of coupon holders. The pluralities of coupon holders are disposed throughout the non-metallic support structure wherein the pluralities of coupon holders are designed to secure a metal coupon on at least two edges.
1 . An apparatus comprising:
a) a non-metallic coupon holder assembly comprising:
i. a non-metallic support structure; and
ii. a plurality of coupon holders disposed throughout the non-metallic support structure wherein the plurality of coupon holders are designed to secure a metal coupon on at least two edges.
2 . The apparatus of claim 1 , wherein the non-metallic coupon holder assembly is made of quartz.
3 . The apparatus of claim 1 , wherein the coupon holders comprise a pair of ridges spaced evenly apart at a distance capable of accommodating the thickness of the metal coupon.
4 . The apparatus of claim 1 , wherein the coupon holders secure both the top edge of the metal coupon and the bottom edge of the metal coupon.
5 . The apparatus of claim 1 , wherein the plurality of coupon holders are evenly spaced along the non-metallic support structure.
6 . The apparatus of claim 1 , wherein the non-metallic coupon holder assembly is multi-level with a plurality of coupon holders disposed throughout the non-metallic support structure on each level.
7 . An apparatus comprising:
a) a non-metallic coupon holder assembly made of quartz comprising:
i. a non-metallic support structure; and
ii. a plurality of coupon holders disposed throughout the non-metallic support structure wherein the plurality of coupon holders are evenly spaced along the non-metallic support structure and are designed to secure both the top edge of the metal coupon and the bottom edge of the metal coupon and the coupon holders comprise a pair of ridges spaced evenly apart at a distance capable of accommodating the thickness of the metal coupon;
wherein the non-metallic coupon holder assembly is multi-level with a plurality of coupon holders disposed throughout the non-metallic support structure on each level.
8 . A method comprising:
a) inserting a metal coupon into a non-metallic coupon holder assembly comprising:
i. a non-metallic support structure; and
ii. a plurality of coupon holders disposed throughout the non-metallic support structure wherein the coupon holders are designed to secure the metal coupon on at least two edges;
b) subjecting the metal coupon to a corrosion test for a specified period of time; and
c) calculating a corrosion rate of the metal coupon by calculating the weight loss of the metal coupon over the specified period of time.
9 . The method of claim 8 , wherein the non-metallic coupon holder assembly is made of quartz.
10 . The method of claim 8 , wherein the coupon holders comprise a pair of ridges spaced evenly apart at a distance capable of accommodating the thickness of the metal coupon.
11 . The method of claim 8 , wherein the coupon holders secure both the top edge of the metal coupon and the bottom edge of the metal coupon.
12 . The method of claim 8 , wherein the plurality of coupon holders are evenly spaced along the non-metallic support structure.
13 . The method of claim 8 , wherein the non-metallic coupon holder assembly is multi-level with a plurality of coupon holders disposed throughout the non-metallic support structure on each level.
