ISO 18755 Specific Heat by Laser Flash at High Temperatures
The ISO 18755 standard provides a precise method for measuring the specific heat capacity of materials through laser flash analysis (LFA) under high-temperature conditions. This service is particularly valuable in sectors such as aerospace, automotive, and power generation where material integrity at elevated temperatures is critical.
Specific heat by LFA at high temperatures involves exposing a small cylindrical specimen to a short pulse of intense laser light. The subsequent rise in temperature is monitored using an optical sensor, providing data on the thermal diffusivity of the sample. From this information and known physical constants, the specific heat capacity can be accurately calculated.
The process begins with thorough preparation of the material specimen, ensuring it meets the required dimensions for accurate testing. The test environment must also meet stringent temperature control criteria to ensure repeatability and accuracy. Our laboratory adheres strictly to ISO 18755 guidelines to deliver reliable results that are essential for compliance with international standards.
The importance of this service cannot be overstated, especially in industries where material failure at high temperatures can lead to catastrophic consequences. By providing accurate specific heat data under these conditions, we enable our clients to make informed decisions about their materials' suitability and durability.
For quality managers and R&D engineers, understanding the thermal properties of materials is crucial for product development and lifecycle management. This service offers insights into how materials behave at high temperatures, which is essential for optimizing performance and ensuring safety. Compliance officers will appreciate the ability to verify compliance with international standards like ISO 18755, ensuring that products meet regulatory requirements.
