| Title | Plastics - Differential Scanning Calorimetry - General principles |
| Scope | This international standard specifies general principles of differential scanning calorimetry like description of the principle and apparatus, sampling, calibration and general aspects of the procedure and test report common to all following parts. Details on performing distinct determinations for special methods are given in subsequent parts of this international standard. |
| Comment | This method is suitable for comparative measurements on polymeric materials. However, the results obtained may be influenced by systematic errors such as incorrect calibration, baseline correction, specimen conditioning and preparation etc. It is strongly recommended to establish polymeric reference materials (similar to those materials routinely analysed) for comparative analysis parallel with the materials being tested. This allows for comparison of data obtained from different laboratories, instruments, test dates, specimen conditioning and preparation procedures etc. NPL has been running a series of Department of Trade and Industry funded projects in collaboration with industry and interlaboratory tests have been conducted in both DSC and DMA techniques.
