Condition monitoring and diagnostics of machines - Thermography - Part 1 : general procedures

ISO 18434-1:2008 provides an introduction to the application of infrared thermography (IRT) to machinery condition monitoring and diagnostics, where "machinery" includes machine auxiliaries such as valves, fluid and electrically powered machines, and machinery-related heat exchanger equipment. In addition, IR applications pertaining to machinery performance assessment are addressed. ISO 18434-1:2008: introduces the terminology of IRT as it pertains to condition monitoring and diagnostics of machines; describes the types of IRT procedures and their merits; provides guidance on establishing severity assessment criteria for anomalies identified by IRT; outlines methods and requirements for carrying out IRT of machines, including safety recommendations; provides information on data interpretation, and assessment criteria and reporting requirements; provides procedures for determining and compensating for reflected apparent temperature, emissivity, and attenuating media. ISO 18434-1:2008 also encompasses testing procedures for determining and compensating for reflected apparent temperature, emissivity, and attenuating media when measuring the surface temperature of a target with a quantitative IRT camera.

ZOOM ON ... the Requirements department
To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.

With Requirements, quickly access the main part of the normative text!
