How to test the compressive strength of concrete when the thickness of the concrete component is less than 70?

Can core sampling be used for correction or strength measurement when the thickness of concrete components is less than 70? The article describes the method of using small aspect ratio core samples to test the compressive strength of thin-walled concrete components.

This method is a local standard and has recently been abolished.
