Fender Compression Test and Angular Fender Compression Test

Testing is carried out in two stages: to prove behavior of the generic fender type, and then to confirm that performance of fenders made for each project meet the required performances.

Based on PIANC 2002: Guidelines for the Design of Fender Systems: Appendix A, Fender Testing is carried out to determine the effects of environmental factors on the performance of various fender types. CV method verification testing is routinely carried out on all significant orders to confirm the Rated Performance Data (RPD). JIER Fenders’ tests are witnessed by BV according to PIANC 2002.

FENDER COMPRESSION TEST

Compress fender along its longitudinal axis between two parallel flat plate surfaces to a compressed dimension of a certain percent of its original height. Record load and the corresponding deflection at 6 mm 1/4 inch increments and plot as a graph of load versus deflection. The Load-Deflection curve shall then be integrated to generate an Energy-Deflection curve for the fender. After compression of the fender to a certain percent of its original height, the fender shall be rebound to 98 percent of its original height within 10 minutes after the load is removed.

ANGULAR FENDER COMPRESSION TEST

Compress fender along its longitudinal axis between two flat plate surfaces, at an angle of [0.26] a certain rad a certain degrees to each other, to a compressed dimension of a certain percent of its original height. Record load and the corresponding deflection at 6 mm 1/4 inch increments and plot as a graph of load versus deflection. The Load-Deflection curve shall then be integrated to generate an Energy-Deflection curve for the fender. After compression of the fender to a certain percent of its original height, the fender shall rebound to 98 percent of its original height within 10 minutes after the load is removed.
