This standard is used to determine the intrinsic viscosity of cellulose, in particular the sensitivity of cellulose to degradation by heat, light, acid, etc. during processing or purification. The intrinsic viscosity value can be converted to the degree of coalescence (DP) or intrinsic flowability. The standard applies to cellulose samples with an intrinsic viscosity of 15 dl/g or less. The measurement result is affected by the shear rate, which has less effect on low molecular weight samples. The standard does not specify all safety issues, and the user needs to determine the safety measures and regulatory requirements.
