ISO/TS 23878:2024 is a technical specification published by the International Organization for Standardization (ISO). Specifically, it focuses on nanotechnologies and outlines a method for evaluating nanopores in materials using positron annihilation lifetime measurement. This standard provides guidance on using a 22Na positron source to measure the lifetime of positrons in materials, which can reveal information about the presence and characteristics of nanopores.
