BOXED ALMEN STRIPS

· Do not remove the shrink wrap covering the box of strips until the strips will be used.

· Do not discard the VCI (Volatile Corrosion Inhibitor) paper after opening the box. VCI paper is a very effective material for preventing rust and corrosion.

· Return unused strips to the original EI box and replace the VCI paper, making sure the unprinted side of the paper is in contact with the strips.

BULK ALMEN STRIPS IN BAGS

· Electronics Inc. packages bulk Almen strips in blue VCI polyethylene bags. In addition, EI places a 12” x 12” sheet of VCI paper in the bags.

· The Almen strips should remain in the blue bag until the time of use. Always return unused strips to the VCI bag and replace the VCI paper, making sure the unprinted side of the paper is in contact with the strips.

· Before returning Almen strips to storage, close the blue VCI bag. Fold the leaves of the box to close it tightly or tape the box shut. Do not leave the strips open to the environment.

RECOMMENDED CLIMATE CONTROL

· Avoid major temperature changes when storing or using Almen strips. In particular, do not move strips from a warm environment to a cold one. This can cause condensation on the surface of the strips

Recommended storage conditions are 65°-75°F (18˚C-24˚C) and a 20% – 60% relative humidity.
