Foreword

GB/T 19466 "Plastic Differential Scanning Calorimetry (DSC)" is divided into the following seven parts. - Part 1. General; - Part 2. Determination of glass transition temperature; - Part 3. Determination of melting and crystallization temperature and enthalpy; - Part 4. Determination of specific heat capacity; - Part 5. Determination of characteristic reaction temperature, reaction time, reaction heat and conversion rate; - Part 6. Determination of oxidative induction time (isothermal OIT) and oxidation induced temperature (dynamic OIT); - Part 7. Determination of crystallization kinetics. This part is part 4 of GB/T 19466. This part is drafted in accordance with the rules given in GB/T 1.1-2009. This part uses the re-drafting method to modify ISO 11357-4..2014 "Plastic Differential Scanning Calorimetry (DSC) Part 4. Ratio Determination of heat capacity ". The technical differences between this section and ISO 11357-4..2014 are as follows. --- on the normative reference documents, this part has made a technical differences in the adjustment to meet China's technical conditions, adjust the situation The situation is reflected in Chapter 2, "Normative references", as follows. ● replace ISO 472 with equivalent GB/T 2035 with international standard; Replace GB 11357-1 with GB/T 19466.1-2004 with equivalent international standard; ● Added references to GB/T 6379.2-2004 to meet the need for computational precision; ● the reference file ISO 80000-1 to GB/T 8170, the domestic calculation of the rules do not generally use ISO 80000-1 method; --- Chapter 10 to remove the ISO precision, to our precision data. This section is proposed by the China Petroleum and Chemical Industry Association. This part is headed by the National Plastics Standardization Technical Committee (SAC/TC15). This part of the drafting unit.

1 Scope

This part of GB/T 19466 specifies the test method for determining the specific heat capacity of plastics by differential scanning calorimetry (DSC).

2 normative reference documents

The following documents are indispensable for the application of this document. For dated references, only the dated edition applies to this article Pieces. For undated references, the latest edition (including all modifications) applies to this document. GB/T 2035 Plastics terms and their definitions (GB/T 2035-2008, ISO 472..1999, IDT) Accuracy (accuracy and precision) of measurement methods and results - Part 2. Determination of standard measuring methods GB/T 6379.2-2004 Method of Reproducibility and Reproducibility (ISO 5725-2..1994, IDT) Representation and Judgment of Numerical Correction Rule and Limit Value of GB/T 8170 Plastics - Differential scanning calorimetry (DSC) - Part 1.

3 terms and definitions

GB/T 2035 and GB/T 19466.1-2004 and the following terms and definitions apply to this document. 3.1 Calibration material Specific heat capacity is known. Note. Normally, 99.9% or more pure alpha-alumina (eg artificial sapphire) can be used as the calibration substance. 3.2 Specific heat capacity (constant pressure) specificheatcapacity (atconstantpressure) Cp At constant pressure, the mass of the mass per unit mass increases the heat required by 1K. Note 1. Specific heat capacity calculated according to formula (1). Cp = m-1Cp = m-1 (dQ/dT) p (1) Where. m - the quality of matter; (KJ · kg-1 · K-1) or coke per gram Kelvin (J · g-1 · K-1), the lower footer p represents the isobaric process; dQ --- the heat required for the material to heat up the dT. In the temperature range where the primary phase transition does not occur, the formula (2) is established. (dQ/dT) = (dt/dT) × (dQ/dt) = (heating rate) -1 × heat flow rate (2) Note 2. In the event of phase transition, the heat capacity is not continuous. The calories consumed are not all used to heat up, and some of the heat is used to make the material higher Of the state. Therefore, the specific heat can be measured reasonably outside the phase transition zone. ......
