This section uses the redrafted method to modify the ISO 1133-1.2011 "plastic thermoplastic melt flow rate (MFR) And Measurement of Melt Volume Flow Rate (MVR) Part 1. Standard Methods. The main technical differences between this part and ISO 1133-1.2011 and its reasons are as follows. --- With regard to normative references, this standard has made adjustments with technical differences to adapt to China's technical conditions and adjust the situation. The focus is reflected in Chapter 2, “Normative References,” and the specific adjustments are as follows. ● Replaced ISO 4287 with GB/T 3505-2009 equivalent to international standards; ● Replaced ISO 1133-2 with GB/T 3682.2-2018 modified to adopt international standards; ● Replaced ISO 6507-1 with GB/T 4340.1-2009 modified to adopt international standards. --- Increased precision of the test method (Chapter 11) to make the implementation of the standard more instructive. This section is consistent with the standard structure of ISO 1133-1.2011, and the following changes have been made in the editing. --- Numbered formulas; --- The contents of the selection test temperature and nominal load in the table of Appendix A are changed to the second paragraph of Appendix A; --- Appendix B lists the MFR and MVR test conditions and codes specified in the relevant standards for thermoplastics, and gives the use of Instructions.

Rheological behavior Materials that are sensitive to the test time-temperature history, such as materials that degrade during testing, are recommended to use in accordance with ISO /IEC 14598-2. Note. When GB/T 3682 parts are released, there is no evidence to show that using GB/T 3682.2 to test stability materials is more accurate than using this part of the test results. better. Plastic Thermoplastic Melt Mass Flow Rate (MFR) and melt volume flow rate Determination of (MVR) Part 1. Standard Methods Warning - Persons using various parts of GB/T 3682 should have practical experience in regular laboratory work. Part of GB/T 3682 Points do not indicate all possible security issues. Users have the responsibility to take appropriate safety and health measures and ensure compliance with relevant national laws Regulatory conditions.1 ScopeThis part of GB/T 3682 specifies the determination of the mass flow rate of thermoplastic melts under specified temperature and load conditions. (MFR) and melt volume flow rate (MVR) methods. Method A is a mass measurement method, and method B is a displacement measurement method. usually, Thermoplastics Materials Standards This standard specifies the test conditions for determining the melt flow rate. Thermoplastics are listed in Appendix A Used test conditions. The melt volume flow rate is particularly suitable for the comparison of filled and unfilled thermoplastics, as well as for different fill levels of filler materials. Compare. If the melt density of the material at the test temperature is known, the MFR can be determined from the MVR measurement and vice versa. This section can also be used for thermoplastics whose rheological behavior is affected by hydrolysis (chain scission), polycondensation and cross-linking, but only if these effects and The repeatability and reproducibility of the test results apply only when they are within an acceptable range. This section does not apply to materials whose rheological behavior is significantly affected during the test. In these cases, GB/T 3682.2 can be used. Note. The shear rate in this section is much smaller than the shear rate used in the processing under normal conditions, so the various thermoplastic plastics obtained in this section Material data does not necessarily correlate with the performance exhibited during processing. The methods A and B specified in this part are mainly used for quality control.2 Normative referencesThe following documents are indispensable for the application of this document.
