What is a coupon in steel?

Steel coupons are small samples that are removed from the existing structure and are used for subsequent analysis and testing. Coupons are required for both tensile and chemical testing.

What is a coupon in testing?

A coupon or test coupon is a printed circuit board (PCB) used to test the quality of a printed wiring board (PWB) fabrication process. Coupons are then inspected to ensure proper layer alignment, electrical connectivity, and cross sectioned to inspect internal structures.

What is a tensile coupon?

ABSTRACT: Tensile coupon tests are commonly carried out to determine the material properties of metallic materials in research and industry. The proposed procedures are able to eliminate possible errors and provide clear guidelines for tensile coupon tests.

What is coupon level?

3.2.2.3 Coupon level At the coupon level, a simple system of part(s), tool(s), and processing environment as shown in Figure 3.2(c) is considered. As a simple example, the manufacturing process of a thermoset-based flat composite part on a flat tool is depicted in Figure 3.4(a).

What is the purpose of production test coupon?

“In addition to the Code requirements production test coupons shall be provided for any vessel subject to PWHT. The mechanical tests to be carried out on these test coupons shall be those required for type approval of the corresponding weld procedures, and their results must satisfy the same criteria”.

What is a coupon in engineering?

A piece pf metal from which a test specimen is to be prepared-often an extra piece (as on a casting or forging) or a separare piece made for test purposes (such as a test weldment)

What is a coupon study?

The use of carrier testing, or coupon studies, is well established in evaluating the efficacy of a disinfectant against microbial, adventitious agent, or mycoplasma contamination. The testing coupons are representative of surfaces in your cleanroom environment (Table 1).

How do you test for corrosion coupon?

Corrosion coupons are pre-weighed and measured metal strips which are mounted in a special pipe system called a coupon rack. They are used to estimate the rate of metal corrosion by comparing the initial weight with the weight following 60, 90 or 120 days of exposure to the water in the system.

What is a pipe coupon?

a weld or braze assembly for procedure or performance qualification testing. The coupon may be any product from plate, pipe, tube, etc., and may be a fillet weld, overlay, deposited weld metal, etc. EDIT: From ASME Sec IX Definitions.

What is corrosion coupon & probe?

Corrosion coupons, probes, holders are corrosion-sensing devices that can detect the rate of corrosion in any process environment. Corrosion coupons are also known as corrosion monitoring coupons.
