Corrosion Coupons & Test Racks

Accepta offer a range of corrosion monitoring services for many of the metals most commonly found in engineering systems including mild steel, copper, stainless steel, brass and more.

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.


Coupon Materials Available

The following materials are available as corrosion coupons:

  • Mild Steel
  • Copper
  • Stainless Steel
  • Aluminium
  • Brass
  • Galvanised mild steel

Key Features

  • Standard 3" x ½" size
  • Pre weighed to 0.1mg
  • Individually packed in sealed heavy duty polythene bags
  • Fixing hole as required

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.

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. Accepta's corrosion coupon test racks have a serpentine shape allowing the water to flow along each coupon from the holder in the same direction.
