Characteristics:

• Two sample chamber design for high efficiency
• Timer adjustable up to 99 min.​

Test procedure:

• Take 50 cleaned caps and divided them into two group, each group with 25 caps, weigh two group caps, accuracy should be 0.1mg
• Put caps into each sample chamber, turn 50 minutes (time adjustable) at a speed of  20 RPM per minute
• Take out the caps and clean the wear film attached on the cap ,weigh them again, accuracy should be 0.1mg
• Calculate the loss weight of the two group’s caps. Take the average of two group loss weight as the cap abrasive wear value.
• Compare to standard qualified range to determine if the value is within the range.
