Standard Practice for Dilute-Solution Viscosity of Photodegradable Polystyrene
Scope
Z217.1
1.1 This practice outlines a method for the determination of the dilute solution viscosity of polystyrene products in tetrahydrofuran (THF). It is applicable to nondegraded and photodegraded polystyrene samples. It is used for the determination of relative viscosity (viscosity ratio), inherent viscosity (logarithmic viscosity number), intrinsic viscosity (limiting…
Test Method for Tumbling Friability of Degradable Polystyrene Foams
1. Scope
1.1
This method determines the degradation of polystyrene foams by measuring mass
loss due to a combination of abrasion and impact produced by a laboratory
tumbling device.
1.2
The values stated in metric (SI) units are to be regarded as the standard. The
values in parentheses are provided for information only.
1.3
This Standard does not purport to address all of the…
