Maya went pale.
Maya canceled the audit spot checks. She spent the 300 francs on an official, current PDF from the IEC webstore. It arrived in 10 minutes. Using the correct 2023 requirements, she and Tom found two older junction boxes that would have failed the new torque test. They fixed them before the auditor arrived. iec 60079 part 17 pdf free download
Tom continued, “That free PDF you downloaded? It’s obsolete. Worse, it’s missing critical annexes. The official standard isn’t expensive – it’s insurance. You don’t gamble with explosion protection.” Maya went pale
Maya had a problem. An auditor was arriving in 48 hours to verify their hazardous area equipment records, specifically against , the standard governing the inspection and maintenance of electrical installations in explosive atmospheres. Her company’s hard copy was missing, and purchasing a new official copy would take five business days and cost 300 Swiss francs. It arrived in 10 minutes
“The internet. It’s free. It’s IEC 60079-17.”
“Here,” she said. “Use these for tomorrow’s spot checks.”
Tom walked her to a decommissioned junction box in Zone 1. He opened it. “This box has flameproof threads. The 2016 standard says a visual inspection is enough. But the – which your free copy isn’t – added a new requirement: torque verification on all flameproof entries. Last year, a plant in another state skipped that new check. Vibration loosened a gland. Gas leaked. The explosion injured three people.”
