Capsule brittleness testing
WebThe experts at the Smithers rubber testing lab have a wealth of experience in determining the low temperature properties of vulcanized and thermoplastic rubber. Brittleness testing determines the lowest temperature at which materials do not exhibit brittle failure, or the temperature at which 50% of test pieces fail under specified conditions. Web• Capsules are smaller in size (average length less than lower tolerance limit) or vary in size. • Capsules are stuck together in lumps and do not come apart. • Capsules are …

WebOct 20, 2008 · Recent guidelines for submitting documentation for the stability of human drugs and biologics to the FDA have requested test data for capsule brittleness. A simple test has been developed using a compression gauge to quantify the force required to fracture and/or shatter hard gelatin capsules.
WebDuring a test it is important to visually monitor the start of fracture. Fracturability (single break) is usually represented by a characteristic sharp curve (usually a thin triangle shape). In a curve such as that shown above, the following are often recorded: • Distance at break = ‘fracturability'/’brittleness' (mm) minimum cores needed for minecraft serversWebThere is no brittleness risk to the capsules at these low levels.
