Many engineering firms do exactly this for their quality departments.
Word spread the way things do in small towns: through a customer with a recommendation, an apprentice who saw the coupling run smoother than anything they'd seen in months. Orders returned—one-off repairs at first, then short runs for local manufacturers who needed a nimble supplier. People liked that Ana could promise tolerances and deliver parts that met them. They liked that she paid attention to the subtle language of standards. The ISO 20457 table, once just a relic, became the backbone of her shop's revival.
