What is a coupon in testing?

A coupon is a small sample of a more extensive test material. Testing larger materials or products can prove to be expensive and complex; therefore, tensile coupon testing is an effective and cheaper alternative. Technicians prepare the sample piece in a way that its properties are representative of the whole material. Tensile coupon testing is essential to ensuring the integrity of a product is up to relevant standards. In some cases, multiple coupons must undergo testing to provide margins of error in the case of material differences. ATS meticulously prepares coupons because external stimuli that would not affect the larger material may drastically impact the coupon.

Do you need all this in an ambient environment or do you require low (-55 deg C), even cryogenic temperatures (-180 deg C), or elevated (80 deg C) or really hot ( deg C), temperatures. Does the air need to be dry or humid, corrosive or even worse. Does your article need to be saturated with water or something else.
