In ISO standards, which characteristic is least likely to be monitored?

In the context of ISO standards, monitoring characteristics such as temperature, particulate count, and humidity is essential for maintaining quality control and ensuring compliance with established benchmarks in various settings, particularly in environments like cleanrooms or controlled production areas. Temperature influences the stability of products, while humidity levels can affect processes and outcomes, especially in pharmaceuticals or biotechnology fields. Additionally, monitoring particulate count is crucial for ensuring air quality and preventing contamination.

Lighting conditions, while important for some operational aspects, are typically less critical in terms of direct quality control and compliance monitoring within ISO frameworks. Lighting primarily affects worker performance and visibility rather than the inherent quality of products or processes. Consequently, while it may be considered in some specific contexts or settings, it is generally not prioritized in ISO standard monitoring compared to the other factors mentioned.
