Finding inspection providers with a deep understanding of specific industry requirements can be challenging. Companies must ensure that the chosen provider is familiar with the unique needs and standards of their particular sector to guarantee effective and compliant infrared thermography inspections.
6. Regulatory Compliance
Identifying providers knowledgeable about relevant regulations can be difficult, making it essential to ensure compliance to avoid legal issues.
7. Reliability and Reputation
Assessing the credibility of potential providers can be daunting, as marketing materials may be misleading. Seeking references and reviews can help identify trustworthy partners.
By being aware of these challenges, businesses can approach their search for a thermal inspection company with greater clarity and confidence, ultimately leading to better outcomes for facility management.
Finding the Right Provider
Finding a reliable infrared thermography inspection company is not just about cost; it involves ensuring that the selected provider has the necessary certifications, knowledge, experience, and infrared thermal imaging equipment to deliver accurate and actionable insights. With the right partner, organisations can effectively monitor and maintain their facilities, preventing costly repairs and enhancing operational efficiency.
However, the process can be daunting without proper guidance and understanding of what to look for in a thermal inspection service. This blog post aims to shed light on the key factors to consider when assessing potential infrared thermal inspection companies, helping you make an informed decision for your facilities.
To make an informed decision, it’s essential to evaluate potential providers based on three key areas:
Proficiency, Presentation, and Performance.
Here’s a detailed breakdown of each category:
#01 Proficiency
Proficiency refers to the qualifications and expertise of the thermographers conducting the infrared thermography inspections.
Key factors to consider:
Professional Certification:
- Ensure that the thermographers are at minimum Level-1 Infrared Thermography certified by established training institutes like the Institute of Infrared Thermography (IIRT) that adhere to recognized industry standards, such as ASNT SNT-TC-1A or ISO 18436-7.
- Certification indicates that they have undergone rigorous training and possess the necessary skills to operate thermal imaging equipment effectively.
- Additionally, check if they have other relevant certifications or licenses. Eg. Licensed Electrical Worker (LEW) for electrical facilities
Proficiency Experience:
- Look for companies with a solid track record in infrared thermography with more than 50 inspections conducted.
- Inquire about their experience in your specific industry, as different sectors may have unique challenges and requirements. A company that has worked with similar facilities will likely understand your needs better.
- Ensure they implement Pre-Inspection Survey & Post Rescan Routine as standard practice.
- A pre-inspection survey and post-rescan routine ensure thoroughness and accuracy in thermal inspections. The pre-survey identifies key areas and safety concerns, while the post-rescan verifies findings and enhances documentation. Choosing a company that implements these practices guarantees reliable insights for maintaining your facilities’ efficiency.
Project References & Case Studies:
- Ask for references and review case studies to assess their ability to handle various inspection scenarios.
- This will give you insights into their problem-solving capabilities and customer satisfaction.
#02 Presentation
Presentation encompasses how the thermographic inspection findings are communicated to you, including the clarity and quality of reports.
Key aspects to look for:
Precise Captures:
- Both thermograms and digital images should be sharp and clear to ensure accuracy when identifying anomalies.
- While this is also a factor of the resolution of the infrared camera, it is also the skill of the thermographer to ensure thermograms are focused.
Presentation of Reports:
- A professional infrared inspection company should provide comprehensive reports that clearly outline the findings.
- They should be systematic and organised, eg. timed, dated and arranged by location.
- Look for reports that include not just thermal images, but followed by detailed findings with a clear executive summary, annotated diagrams and explanations of any anomalies detected for facilitating better decision-making. Eg. For electrical inspection, if it is crucial, load conditions and information should be included.
- Beyond just identifying issues, the report should offer actionable recommendations for remediation. This helps you prioritise repairs and maintenance based on the severity of the findings.
Post-Inspection Procedures:
- In today’s fast-paced environment, timely reporting is essential. Ensure that the company has a reputation for delivering reports promptly after the inspection, allowing you to act quickly on any identified issues.
- Verify whether they offer post-inspection follow-ups for any identified issues that may necessitate a subsequent visit to reassess the problem areas.
#03 PERFORMANCE
Performance focuses on the quality of the infrared thermography equipment used and the overall effectiveness of the inspection process.
Key considerations:
Professional Tools:
- Their infrared cameras used should be of high quality, with features such as:
- High resolution (at least 320×240 IR resolution)
- Excellent thermal sensitivity or NETD (less than 40mk/0.04°C or better)
- This ensures that even minor temperature differences are detected, leading to more accurate assessments. These are the minimum, other features are certainly big bonuses depending on your requirements.
Look for companies that utilise trusted brands in thermal imaging technology, known for delivering reliable, consistent, and comprehensive results. Additionally, consider brands with which you have had positive experiences and that you trust for your specific needs.
Periodic Calibration:
- Periodic calibration of thermal imaging equipment (at least annually) is essential to maintain accuracy and reliability in inspections.
- Ensuring your inspection company conducts regular calibrations helps prevent erroneous readings, ultimately safeguarding against potential safety hazards and costly maintenance issues.
Powerful Processing:
- Utilising appropriate reporting tools enhances the clarity and effectiveness of thermal inspection reports.
- These tools facilitate detailed documentation, easy data analysis, and clear visual presentations, ensuring stakeholders can quickly understand findings and make informed decisions for maintenance and repairs.
Conclusion
Choosing the right infrared thermal inspection company involves a careful assessment of their Proficiency, Presentation, and Performance.
