25、s - Differential scanning calorimetry (DSC) - Part 3: Determination of temperature and enthalpy of melting and crystallization (ISO 11357-3) 3 Terms and definitions For the purposes of this document, the following terms and definitions apply. 3.1 phase change material PCM a substance which is capabl

26、e of storing and releasing thermal energy in the form of latent heat (enthalpy), over a specific temperature range during which the material changes phase (from solid to liquid or from liquid to solid), thus buffering external temperature changes Note 1 to entry: These temperature ranges are usually

27、 close to skin temperature. 3.2 pure PCM PCM in its free form 3.3 micro-encapsulated PCM PCM contained in a spherically shaped particle with a closed shell and having a diameter in the range of 1 m to 1 mm DIN EN 16806-1:2016-07 EN 16806-1:2016 (E) 5 3.4 textile containing PCM textile containing the

28、 phase change material inside the fibres or yarns; or having the PCM applied to the fibre, yarn or textile surface 3.5 phase change temperature peak temperature at which the PCM changes either from the solid to the liquid (melting temperature) or from the liquid to the solid state (crystallisation t

29、emperature) Note 1 to entry: Ideally, the two phase change temperatures should be identical, but in reality a difference will be observed as often material mixtures are used. 4 Principle of test This test determines the enthalpy of fusion and of crystallization, as well as the phase change temperatu

30、res of fibres, yarns and fabrics containing PCM. A differential scanning calorimetry (DSC) method is used. The difference between the rate of heat flow into a specimen and that into a reference crucible is measured as a function of temperature and/or time while the specimen and the reference are sub

31、jected to the same temperature control programme. 5 Test equipment, reagents and materials The DSC test equipment described in EN ISO 11357-1 shall be used. Open aluminium crucibles shall be used to ensure an isobaric measurement. It is recommended to put a lid on the crucible but without sealing it

32、 hermetically. The test equipment shall be calibrated periodically in accordance with the instructions and recommendations of the equipment manufacturer, i.e. with respect to the use and shelf life of calibration standards. The calibration procedure of EN ISO 11357-1 shall be followed. Calibration m

33、aterials should be chosen with a transition temperature as close as possible to phase change temperature of the PCM. The heating rate shall be 5 C/min. NOTE A suitable calibration material is phenyl salicylate (CAS 118558), with a melting temperature of 41,79 C and an enthalpy of fusion of (89,4 0,4

34、) J/g. Other reference materials can be recommended by the suppliers. 6 Test specimens 6.1 Sample conditioning Samples shall be conditioned in the standard atmosphere according to EN ISO 139 (20 C 2 C and 65 % RH 4 % RH) for at least 24 h before determining the mass per unit area. This conditioning

35、only applies to textile materials containing PCM and the dried micro-encapsulated PCM. It does not apply to the pure PCM. 6.2 Sampling and specimen preparation 6.2.1 General The specimen shall be representative of the sample being examined and shall be prepared and handled with care. Particular care

36、 shall be taken to avoid any contamination of the specimen. If the specimen crucible is closed with a lid, this shall not cause any deformation of the bottom of the crucible. Good DIN EN 16806-1:2016-07 EN 16806-1:2016 (E) 6 thermal contact between the specimen and crucible and between the crucible

37、and holder shall be ensured. The mass of the DSC test specimens shall be between 10 and 40 mg, with 10 mg being recommended. It may be necessary for low weight fabrics to put several layers in the same crucible to get the required mass. The tolerance on the weight should be as described in EN ISO 11

38、357-1. A lid shall be pressed on the crucible to ensure a good contact between the textile specimen and the bottom of the crucible. For very thin fabrics or for bulky, fluffy materials it may be necessary to stack, fold or compress the textile material to obtain a good thermal contact with the botto

39、m of the crucible. Care shall be taken to allow pressure release during the measurement (isobaric measurement condition). A new crucible and lid shall be used for each specimen. NOTE Each DSC instrument has its own shape of crucibles and its own press to put the lid on the crucible. Crucibles are no

40、t interchangeable. 6.2.2 Pure PCM Three specimens shall be prepared. Pre-weigh the empty crucible and its lid. Pre-heat the PCM sample to 60 C so that it is in the liquid state. Collect one representative specimen of pure PCM through a micro-pipette with a volume range between 10 to 20 L. Carefully

41、deposit the PCM into the crucible so that the bottom of the crucible is completely covered, without overfilling. Carefully place the lid when sealing the crucible in order to avoid spilling of the PCM. Leave the crucible at room temperature in a desiccator for 20 min to solidify the PCM. Weigh the f

42、illed crucible and determine the weight of the PCM. 6.2.3 Micro-encapsulated PCM The micro-encapsulated PCM product shall be dried at 60 C for at least 24 h to remove all water. The micro-encapsulated PCM product shall then be conditioned as described in 6.1. The sample size should be sufficient to

43、prepare five DSC specimens. Three of them shall be tested; if the coefficient of variation is too high (see 7.2) the other two shall also be tested. Prepare five DSC specimens in accordance with 6.2.1. 6.2.4 Fibres and yarns Five representative test specimens shall be taken from the fibre or yarn sa

44、mple and prepared in accordance with 6.2.1. Three of them shall be tested; if the coefficient of variation is too high (see clause 7.2) the other two specimen shall also be tested. 6.2.5 Fabrics Test specimens shall be taken from a fabric sample of at least 50 cm length over the entire width of the

45、fabric. From this fabric sample, five specimens shall be taken to determine the mass per unit area of the fabric in accordance with EN 12127. Representative test specimens for the DSC analysis shall be taken from three of the five specimens used for the determination of mass per unit area. One DSC s

46、pecimen shall be taken from each of these three mass specimens. The two remaining mass specimens shall be kept for additional tests in case of excessive scattering of test results or if test results are discarded. Care should be taken to ensure representativeness of the specimens. In the case of mul

47、ti-layered (e.g. coated, laminated or stacked) substrates, specimen shall be taken in a manner that includes all layers of DIN EN 16806-1:2016-07 EN 16806-1:2016 (E) 7 the sample. In the case of heterogeneous samples, specimens with different composition shall be taken. As many different zones as po

48、ssible shall be sampled taking into account the relative surface area of the fabric. Deviations from the above sampling procedures may be agreed on by the involved parties. This deviating sampling procedure then shall be clearly described in the report. 7 DSC test procedure 7.1 General Test specimen

49、s and reference specimens are subjected to a temperature control programme, which contains a heating-cooling-heating thermal cycle at a rate of 5 C/min under a controlled inert atmosphere. The cycling shall be performed between a low temperature, Tlow, of 20 C and a high temperature, Thigh, of 60 C. The base line (as defined in 7.2) before and after the phase change transition peak shall be stable over a range of 20 C. If this condition i
