ASME PTC 52:2020 (R2026)

This Code applies to testing of solar-to-thermal conversion systems for parabolic trough, linear Fresnel, and power tower CSP systems. A unique feature of these systems is the variability of the input energy from the sun. Therefore, recommendations regarding the instrumentation required to measure the DNI are provided in this Code.

This Code also provides guidance on thermal energy storage systems that are often integral parts of CSP plant designs. This Code recognizes that many forms of energy storage systems with varying test goals are likely to be of interest to the industry. In the absence of any other Code-level guidance, this Code provides input related to testing thermal storage systems in Nonmandatory Appendix A.
