Test parts for hardness, using hardness testing equipment, or by examining and feeling samples.

“Test parts for hardness, using hardness testing equipment, or by examining and feeling samples.” is a supplemental task performed by Heat Treating Equipment Setters, Operators, and Tenders, Metal and Plastic. Among the occupation's 26 rated tasks, workers place it 15th by importance (#12 most important). About 54% of workers say it is relevant to their job.

This is a single occupation-specific task statement from O*NET. The figures below describe how central the task is to the job and what independent studies measure about AI and this kind of work — not a prediction that the task will be automated.

Work activities this task rolls up to

O*NET groups concrete tasks into broader work activities shared across many occupations.

• Inspect completed work or finished products. in Inspecting Equipment, Structures, or Materials

AI exposure

The OpenAI / Eloundou “GPTs are GPTs” study rates this task E0. No direct exposure — current language models give little or no time savings on this task.

Exposure measures whether a model could meaningfully speed the task up — it is an estimate of overlap with model capabilities, not a measure of whether the work will be done by software. The study's intermediate score (β) for this task is 0.00. Automation potential label: T0.

How AI is actually used on this kind of task
