Standard Method for Enthalpy Measurement Validation of Differential Scanning Calorimeters
适用范围：<p>This test method may be used to determine and validate the performance of a particular DSC apparatus.</p> <p>This test method may be used to determine and validate the performance of a particular method based upon a DSC enthalpic measurement.</p> <p>This test method may be used to determine the repeatability of a particular apparatus, operator or laboratory.</p> <p>This test method may be used for specification and regulatory compliance purposes.</p><p id="s00002">1.1 This test method provides procedures for validating enthalpic measurements of differential scanning calorimeters (DSC) and analytical methods based upon the measurement of enthalpy or heat by DSC. Performance parameters determined include calorimetric repeatability (precision), detection limit, quantitation limit, linearity and bias. This method is applicable to both exothermic and endothermic events.</p> <p id="s00003">1.2 Validation of apparatus performance and analytical methods is requested or required for quality initiatives or where results may be used for legal purposes.</p> <p id="s00004">1.3 The values stated in SI units are to regarded as standard. No other units of measurement are included in this standard.</p> <p id="s00005">1.4 <span class="italic">This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.</span>
