HCT36041999
R/1R47-85
This standard specifies the determination method of limiting ylscosity number of palyoxymethylene in dilute sohutlon (containing 2%-methylene) and the characteristic number of ethylene. This standard is applicable to homopolymers and copolymers. 7 Reference standards
The following standards contain provisions that may be used in the standard or in this standard: The standard is published in the appendix, the new version is valid, and all parties using this standard will be subject to the provisions of this standard. The possibility of using a new version of the standard section 7 is changed. GB/11632-1993 The viscosity and characteristic viscosity of the compound required for liquid dispersion are determined according to VTS (162R-1: 1984) 3. The following definitions are used in this specification. The definitions in B632-1 General Part 2. 4 The original high-release type and non-release type are calculated according to the flow time and the change in the concentration of the sieve station and the characteristic viscosity. 5 Reagents and materials
