Corrosion Testing

Most corrosion testing in water systems is carried out with just a few materials. Mild steel is by far the most common, with copper the next most
widely used.

The coupons used in field test are generally 4 x ½ as these fit in corrosion test racks. The ASTM D-2688 standard, entitled "Corrosivity of Water in the absence of Heat Transfer (Weight Loss Methods)" gives much useful information regarding the corrosion testing of water.

ABS TEST RACK

Corrosion test racks (by-pass rigs are designed to permit easy and inexpensive monitoring of corrosion within water systems. Part of the water is diverted from the main flow into the By-Pass rig where it passes over test coupons and is then returned to the system. The test coupons can be removed from the rack without the need to close down the system.

Built to ASTM standard D-2688, with a flow rate of 0.6 to 1.8m/s. Have a serpentine shape allowing the water to flow along each coupon from the holder in the same direction.
