3.45 peening: The mechanical working of metals using impact blows. 3.46 penetrameter: Old terminology for IQI still in use today but not recognized by the codes and standards. 3.47 porosity: Cavity-type discontinuities formed by gas entrapment during solidification or in thermal spray deposit. 3.48 preheat: Metal temperature value achieved in a base metal or substrate prior to initiating the thermal operations. 3.49 recordable indication: Recording on a data sheet of an indication or condition that does not necessarily exceed the rejection criteria but in terms of code, contract or procedure will be documented. 3.50 reportable indication: Recording on a data sheet of an indication that exceeds the reject flaw size criteria and needs not only documentation, but also notification to the appropriate authority to be corrected. All reportable indications are recordable indications but not vice-versa.
This is <strong>API</strong> 577 special way of defining (1) Minor Discontinuities, (2) Significant but Non-Rejectable Discontinuities and (3) Rejectable Discontinuities. recordable indication: Recording on a data sheet of an indication or condition that does not necessarily exceed the rejection criteria but in terms of code, contract or procedure will be documented. reportable indication: Recording on a data sheet of an indication that exceeds the reject flaw size criteria and needs not only documentation, but also notification to the appropriate authority to be corrected. All reportable indications are recordable indications but not vice-versa.
