ASTM E1695 is the ASTM standard for the Standard Test Method for Measurement of Computed Tomography (CT) System Performance. It provides a technical framework for evaluating how a CT system performs, helping users compare equipment results in a consistent way. For buyers, engineers, and quality teams, this matters because measured performance is often central to system acceptance, verification, and ongoing control. ASTM E1695 supports clearer technical decisions when CT imaging capability needs to be assessed.

What is ASTM E1695?

This standard describes a test method focused on measuring computed tomography system performance. In practical terms, it is used to evaluate CT equipment using a defined and repeatable approach rather than informal observation. ASTM E1695 is relevant when a user needs a recognized method for checking how a CT system responds under test conditions. Because it is a test method, it is generally used as part of performance assessment, comparison, or qualification activities tied to CT imaging systems.

Where is ASTM E1695 used?

ASTM E1695 is commonly used in environments that rely on CT systems for inspection, evaluation, or technical measurement. It may be applied by laboratories, inspection teams, equipment vendors, and organizations responsible for verifying CT system capability. The standard is especially useful where consistent performance measurement supports procurement, acceptance testing, or routine quality checks. It fits workflows that depend on repeatable CT results and documented system performance rather than one-time visual review.

Why is ASTM E1695 important?

ASTM E1695 helps bring consistency to CT system performance measurement, which is important when results must be trusted across different users, systems, or test sessions. A recognized test method can support compliance efforts, reduce ambiguity in evaluation, and improve confidence in procurement and acceptance decisions. It also gives quality control teams a clearer basis for comparing performance over time. For organizations using CT technology, this standard can reduce risk and support more defensible technical decisions.
