EMI testing focuses only on emissions.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>How long does<a href=\"https:\/\/tps-electronic.com\/en\/services\/emv-laboratory\/\" target=\"_blank\" rel=\"noopener noreferrer nofollow\"> EMC testing<\/a> take?<\/strong><\/h3>\n\n\n\n<p>Typically 1\u20133 weeks for consumer electronics; more for complex products. Factors: product complexity, standards, lab scheduling, and retesting.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Can products be modified after failing?<\/strong><\/h3>\n\n\n\n<p>Yes. Modifications (layout, shielding, filtering) are common. Retesting depends on scope of changes.<br><\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>What is the cost difference between pre-compliance and full certification?<\/strong><\/h3>\n\n\n\n<p>Pre-compliance \u2248 <strong>10\u201330%<\/strong> of full certification. Full certification ranges from <strong>USD 1,000\u201320,000<\/strong> depending on complexity.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Which standards apply for global markets?<\/strong><\/h3>\n\n\n\n<p>FCC Part 15 (US), EMC Directive 2014\/30\/EU (EU CE marking), IEC 61000 series, CISPR 32\/35, IEC 60601-1-2 (medical), plus local telecom\/RF
