A conduction heat transfer model has been utilized for this purpose. Some expressions have been obtained that relate the main dimensionless numbers of the experiments with the deviations in specific heat capacity, phase change enthalpy and phase change temperature estimations. Although these relations can only be strictly applied to solid materials (e.g. measurements of shape stabilized phase change materials), they can provide some useful and conservative bounds for the deviations of the T-history method. Biot numbers emerge as the most relevant dimensionless parameters in the accuracy of the specific heat capacity and phase change enthalpy estimation whereas this model predicts a negligible influence of the temperature levels used for the experiments or the Stefan number. 000061314 536__ $$9info:eu-repo/grantAgreement/ES/MICINN/ENE2014-57262-R$$9info:eu-repo/grantAgreement/ES/MICINN/ENE2011-22722$$9info:eu-repo/grantAgreement/ES/MICINN/ENE2011-28269-C03-01 000061314 540__ $$9info:eu-repo/semantics/openAccess$$aAll rights reserved$$uhttp://www.europeana.eu/rights/rr-f/ 000061314 590__ $$a1.492$$b2015 000061314 591__ $$aENGINEERING, MULTIDISCIPLINARY$$b26 / 85 = 0.306$$c2015$$dQ2$$eT1 000061314 591__ $$aINSTRUMENTS & INSTRUMENTATION$$b25 / 56 = 0.446$$c2015$$dQ2$$eT2 000061314 592__ $$a0.704$$b2015 000061314 593__ $$aEngineering (miscellaneous)$$c2015$$dQ1 000061314 593__ $$aInstrumentation$$c2015$$dQ1 000061314 593__ $$aApplied Mathematics$$c2015$$dQ2 000061314 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/acceptedVersion 000061314 700__ $$0(orcid)0000-0002-8015-4469$$aDelgado, M. 000061314 700__ $$0(orcid)0000-0001-7360-4188$$aLázaro, A.$$uUniversidad de Zaragoza 000061314 700__ $$0(orcid)0000-0002-2161-3362$$aDolado, P. 000061314 700__ $$0(orcid)0000-0002-9500-974X$$aPeñalosa, C.$$uUniversidad de Zaragoza 000061314 700__ $$0(orcid)0000-0002-2463-7271$$aMarín, J.M.$$uUniversidad de Zaragoza 000061314 700__ $$0(orcid)0000-0002-6101-580X$$aZalba, B.$$uUniversidad de Zaragoza 000061314 7102_ $$15004$$2X$$aUniversidad de Zaragoza$$bDpto.
