Packer Option (PSI/Bar): MIN: 20/1.4 MAX: 50/3.5 Instrument with weight system could have up to 70lbs/31.6Kg weights installed (shipped uninstalled with unit). OTHER: Complies with ISO ASTM D1238 and ISO 1133-1, ISO 1133-2. P/N: M0726(3) | Rev: 012020 | ECO: 51182 www.dynisco.com -12-... -
Page 13: Instrument Maintenance Recommendations
Pneumatic Lift maintenance: The guide rod and the pneumatic cylinder rod can be lubricated. Dynisco Polymer Test suggests that WD-40 or machining oil be used as a lubricant. You can also spray a small amount of WD-40 into the air manifold through the manifold’s air intake to lubricate all internal parts. -
Page 14: Equipment Setup
As a minimum, the lab bench should easily be able to support the indexer and operator (total approx. 300lbs/136.36Kg). DYNISCO POLYMER TEST recommends placing from left to right, if using these options, the melt indexer; sample scale and computer. Shake test the melt indexer for stability. The bench top should also be able to withstand hot dies and tools being dropped on them. -

Page 25: Test Calculations
Method B flow rate must equal Method A. This apparent melt density definition forces the two test methods to agree. DYNISCO POLYMER TEST recommends taking an average of apparent melt densities from at least five separate A/B tests on representative samples of polymer. -
Page 26: Calculations: Method B
The encoder senses distance travelled by following the bottom of the test weight(s) which are at the top of the piston. With all Dynisco Polymer Test Systems flags, Method A and B start in the same place. Flags may be any length desired and a test can have any number as long as the total distance of flags is not longer than the distance from the start point and where the piston would land on the top of the die (≈25.4mm). -
