《GB/T 29305-2012新的和老化后的纤维素电气绝缘材料粘均聚合度的测量》由TC301（全国电气绝缘材料与绝缘系统评定标准化技术委员会）归口，主管部门为中国电器工业协会。
Scope
This standard specifies a standard method for the measurement of the viscosity-average degree of polymerization (DPv) of new and aged cellulose electrical insulating materials. This standard applies to all cellulose insulating materials, such as cellulose insulating materials used in transformers, cables, capacitors and other products. The test method described in this standard is also applicable to the determination of the intrinsic viscosity of kraft paper which can be completely dissolved in the selected solvent after chemical modification. Use caution when applying the test methods described in this standard to waxed kraft paper.
