Abstract

The current invention relates to a bracket for use in conjunction with test coupons to allow for the consistent and long term monitoring of corrosive elements in a facility. The invention is able to have multiple coupons attached to a single bracket allowing for the testing various corrosive elements. Additionally the coupons can be placed at varying angles and locations to allow for a more complete analysis of the environments.

Claims (17)

1. An apparatus for placement of coupons for the evaluation of an environment on materials using test coupons at a single or varying orientation comprising:

(a) a bracket attachment member and a bracket adjustment member,

(b) a coupon attachment member,

(c) a connection member which adjustably connects the bracket attachment member to the coupon attachment member,

(d) a bracket stabilizer disposed on the coupon attachment member and connected to the bracket adjustment member,

(e) coupon attachment sites disposed along a length of the coupon attachment member, and

(f) test coupons suspended on the coupon attachment sites and exposed to the environment, wherein the test coupons are attached in an orthogonal pattern to the coupon attachment sites and oriented at a substantially perpendicular angle relative to the coupon attachment member.

2. The apparatus of claim 1 wherein the bracket attachment member is a u-bar.

3. The apparatus of claim 1 wherein the connection member is adjustable.

4. The apparatus of claim 1 wherein the coupon attachment member is square.

5. A method for sampling effects of degradation on materials in a manufacturing facility wherein the apparatus of claim 1 is placed in a facility and the at least one test coupon is allowed react with the environment and facilitate collecting samples after a predetermined exposure period then replaced with new test coupons.

6. The method of claim 5 wherein the at least one test coupon measures degradation elements from vaporous exposure.

7. The method of claim 5 wherein there are multiple testing coupons.

8. The method of claim 7 wherein the multiple testing coupons are placed at different levels and angles.

9. The method of claim 5 wherein the coupons are collected after a set period and new coupons are placed in a same location for long term testing.

10. The method of claim 5 wherein the coupon attachment member is a square bar.

11. The method of claim 10 wherein the square bar allows for the placement of multiple coupons in an orthogonal pattern.
