Kaedah ujian kekerasan seperti cakera telah digunakan secara meluas untuk mengukur kerosakan karbon aktif berbentuk butiran. Model SSA-39 terdiri daripada cakera tembaga khas 8in (203mm) diameter dan 15 bola keluli 1 / 2 inci (12.7 mm) dan 3 / 8in (9.5 mm) diameter. Cakera bulat mempunyai papan bawah tembaga keras tebal 8mm khas dengan jarak dalam 1092mm dengan ketebalan 3.2mm di tengah. Lembaga bawah dipasang dalam rangka saringan ketinggian penuh standard dan mempunyai tepi yang diperluaskan untuk menumpuk.

The ball-pan hardness test method has been widely used for determining degradation resistance of granulated activated carbons. Model SSA-39 set consists of a special 8in (203mm) diameter brass ball-pan and 15 each steel balls of 1/2in (12.7mm)and 3/8in (9.5mm) diameter. The ball-pan has a special 8mm thick hardened brass bottom plate dished out at 1,092mm inner radius to give a 3.2mm thickness at its center. The bottom plate is mounted in a standard full-height sieve frame with extended rim for stacking.

In use, a 100ml sized sample is placed in the ball-pan with the 30 steel balls and run for 30 minutes in a Sieve Shaker. The heavy ball-pan is loosely stacked (free to rotate) with five regular 8in sieves, sieve pan, and cover. “Hard-ness” of the activated carbon sample is determined by degradation resistance as measured by sieving the ground sample. The SS-30 Ro-Tap, sieves,sieve pan, and cover are all available from Gilson if needed. Est. Ship Wt.: 6lb (3kg).
