It is recommended that the plunger be equipped with at least one peripheral sealing groove. Sampling, based on engineering principles, prior to packaging shall be considered an acceptable alternative. NOTE 5—Preforms or pellets may be used if found necessary; however, flow length may be affected by their use.
ASTM D3123 – 09(2017)
NOTE 4—There is considerable evidence that the test is usable over a wider range of flow lengths, but this has not yet been confirmed by interlaboratory testing. The use of excessive amounts of compound will result in shorter, inconsistent spiral flows. Remember me for one month. Please first verify your email before subscribing to alerts.
