This guide explains how IVA works, when it beats type approval, what inspectors examine on an electric conversion, and how to build an evidence file that passes first time.<\/p>\n    <div class=\"ir-blog-meta-row\">\n      <time class=\"ir-blog-meta-date\" datetime=\"2026-10-06\"><svg width=\"13\" height=\"13\" viewBox=\"0 0 24 24\" fill=\"none\" stroke=\"currentColor\" stroke-width=\"2\"><rect x=\"3\" y=\"4\" width=\"18\" height=\"18\" rx=\"2\"\/><line x1=\"16\" y1=\"2\" x2=\"16\" y2=\"6\"\/><line x1=\"8\" y1=\"2\" x2=\"8\" y2=\"6\"\/><line x1=\"3\" y1=\"10\" x2=\"21\" y2=\"10\"\/><\/svg> October 6, 2026<\/time>\n      <span class=\"ir-blog-meta-dot\">\u00b7<\/span>\n      <span class=\"ir-blog-meta-read\"><svg width=\"13\" height=\"13\" viewBox=\"0 0 24 24\" fill=\"none\" stroke=\"currentColor\" stroke-width=\"2\"><circle cx=\"12\" cy=\"12\" r=\"10\"\/><polyline points=\"12 6 12 12 16 14\"\/><\/svg> 10 min read<\/span>\n    <\/div>\n  <\/div>\n<\/section>\n\n<div class=\"ir-blog-body\">\n  <div class=\"ir-container\">\n    <div class=\"ir-blog-layout\">\n\n      <main class=\"ir-blog-main\">\n        \n\n        \n    <div class=\"ir-blog-toc ir-blog-toc-mobile\">\n      <div class=\"ir-blog-toc-header\"><svg width=\"15\" height=\"15\" viewBox=\"0 0 24 24\" fill=\"none\" stroke=\"currentColor\" stroke-width=\"2\"><line x1=\"3\" y1=\"6\" x2=\"21\" y2=\"6\"\/><line x1=\"3\" y1=\"12\" x2=\"15\" y2=\"12\"\/><line x1=\"3\" y1=\"18\" x2=\"18\" y2=\"18\"\/><\/svg> Contents<\/div>\n      <ol class=\"ir-blog-toc-list\">\n          <li><a href=\"#two-doors-to-the-same-registration-desk\" class=\"ir-toc-link\" data-target=\"two-doors-to-the-same-registration-desk\">Two doors to the same registration desk<\/a><\/li>\n          <li><a href=\"#what-inspectors-examine-on-an-electric-conversion\" class=\"ir-toc-link\" data-target=\"what-inspectors-examine-on-an-electric-conversion\">What inspectors examine on an electric con\u2026<\/a><\/li>\n          <li><a href=\"#building-a-file-that-passes-first-time\" class=\"ir-toc-link\" data-target=\"building-a-file-that-passes-first-time\">Building a file that passes first time<\/a><\/li>\n          <li><a href=\"#markets-differ-know-your-authority\" class=\"ir-toc-link\" data-target=\"markets-differ-know-your-authority\">Markets differ: know your authority<\/a><\/li>\n          <li><a href=\"#the-route-step-by-step\" class=\"ir-toc-link\" data-target=\"the-route-step-by-step\">The route, step by step<\/a><\/li>\n        <\/ol>\n    <\/div>\n\n        <article class=\"ir-blog-article-content\">\n          <p><em>In our guide to [whole vehicle type approval] we described the route built for series production: approve the type once, build thousands. But the zero-emission transition runs ahead of series production. It is full of first vehicles: the converted rigid truck, the prototype terminal tractor, the small batch of electrified cranes. For those, Europe&#8217;s approval framework offers a second door, and knowing when to take it is one of the most valuable pieces of homologation judgement there is.<\/em><\/p><p><strong>Quick answers<\/strong><\/p><ul><li><strong>What is individual vehicle approval?<\/strong> A per-vehicle certification route in which a national authority inspects and approves one specific vehicle instead of a vehicle type<\/li><li><strong>Who uses it?<\/strong> Builders of one-offs and prototypes, converters, importers of non-EU vehicles, and small-volume manufacturers below series thresholds<\/li><li><strong>How does it differ from type approval?<\/strong> Type approval certifies a design once for unlimited production; individual approval certifies one physical vehicle, with requirements adapted to single-vehicle inspection<\/li><li><strong>Does an electric conversion need it?<\/strong> Usually yes, or a national conversion procedure: replacing the driveline invalidates the original approval&#8217;s coverage, and the modified vehicle must be re-approved<\/li><\/ul><h2 id=\"two-doors-to-the-same-registration-desk\">Two doors to the same registration desk<\/h2><p>European vehicle law, framework regulation 2018\/858, recognises that certification effort should scale with production volume. At one end stands whole vehicle type approval with its conformity of production obligations. At the other stands individual approval: the authority looks at one physical vehicle, checks it against an adapted requirements catalogue, and issues an approval valid for that vehicle alone. Between the two sit national small series schemes with relaxed requirements up to modest annual volumes. The United Kingdom mirrors this structure post-Brexit with its IVA scheme and national small series type approval.<\/p><div class=\"tbl-scroll\"><table class=\"compare-table\"><tbody><tr><td><p><strong>Aspect<\/strong><\/p><\/td><td><p><strong>Type approval (WVTA)<\/strong><\/p><\/td><td><p><strong>Individual approval (IVA)<\/strong><\/p><\/td><\/tr><tr><td><p>Certifies<\/p><\/td><td><p>A vehicle type, unlimited units<\/p><\/td><td><p>One specific vehicle<\/p><\/td><\/tr><tr><td><p>Evidence<\/p><\/td><td><p>Full UNECE test reports per system<\/p><\/td><td><p>Inspection plus adapted evidence, often including targeted test reports<\/p><\/td><\/tr><tr><td><p>Economics<\/p><\/td><td><p>High fixed cost, near-zero marginal cost<\/p><\/td><td><p>Low fixed cost, full cost repeated per vehicle<\/p><\/td><\/tr><tr><td><p>Lead time<\/p><\/td><td><p>Months to years<\/p><\/td><td><p>Weeks to months<\/p><\/td><\/tr><tr><td><p>Fits<\/p><\/td><td><p>Series production<\/p><\/td><td><p>One-offs, prototypes, conversions, small batches<\/p><\/td><\/tr><\/tbody><\/table><\/div><p>The judgement call is economic as much as technical. Our rule of thumb from conversion programmes: <strong>below a handful of identical vehicles per year, individual approval wins; above it, start building the small series or type approval case<\/strong>, because per-vehicle inspection costs and scheduling risk scale linearly and patience does not.<\/p><h2 id=\"what-inspectors-examine-on-an-electric-conversion\">What inspectors examine on an electric conversion<\/h2><p>An individual approval of a converted vehicle concentrates on what changed. Four areas dominate the inspection of an electrified heavy vehicle. <strong>Electrical safety<\/strong>: the high-voltage system is assessed against the substance of [ECE R100], isolation, contact protection and marking included, and the battery installation against crash and fire logic. <strong>EMC<\/strong>: the new driveline must show it neither disturbs nor is disturbed, with evidence typically built on [ECE R10] component approvals plus vehicle-level checks. <strong>Braking and stability<\/strong>: an electric driveline changes mass distribution and adds regenerative braking, so the braking evidence must match the vehicle as it now is. <strong>Masses and dimensions<\/strong>: battery weight eats payload, and the approved axle loads must still add up.<\/p><p>The recurring failure mode is not a failed test but a missing story: a vehicle arrives at the inspection lane with excellent engineering and no coherent evidence file. Component e-marks without integration argument, or test reports that describe a different battery position than the one bolted in. Inspectors approve documents as much as vehicles.<\/p><h2 id=\"building-a-file-that-passes-first-time\">Building a file that passes first time<\/h2><p>The successful pattern we see across programmes has four elements. Start from the requirements catalogue of the authority you will actually face, because national schemes differ in detail. Buy evidence where you can: e-marked components turn approval questions into integration questions. Test the vehicle-level items, EMC and braking above all, in a [pre-compliance session] before booking the formal date. And write the file as a narrative: what was changed, what evidence covers each change, signed by the engineers who did the work. A file like that regularly turns a feared inspection into a half-day formality.<\/p><h2 id=\"markets-differ-know-your-authority\">Markets differ: know your authority<\/h2><p>Individual approval is a national procedure inside a European framework, and the national flavour is real. In the Netherlands the RDW runs individual approvals and has built genuine routine in zero-emission conversions, with published requirements for electrically converted vehicles. Germany routes comparable cases through its technical services with their own documentation culture. The United Kingdom, post-Brexit, runs its own IVA scheme for GB registration alongside national small series type approval for modest volumes, and a vehicle destined for both EU and UK customers needs its evidence planned for both regimes from the start. None of this changes the engineering; all of it changes the paperwork, the language of the file and the inspection style. The practical rule: <strong>pick the registration country first, then build the file for that authority<\/strong>, and treat any second market as its own project phase rather than a copy-paste.<\/p><h2 id=\"the-route-step-by-step\">The route, step by step<\/h2><p>Stripped to its sequence, a well-run individual approval of a converted heavy vehicle looks like this. <strong>Scope<\/strong> the applicable requirements with the authority or its technical service, in writing, before cutting metal where possible. <strong>Design against the catalogue<\/strong>, with component choices that bring their own e-marks. <strong>Assemble the evidence file<\/strong> during the build: photographs of hidden installations before panels close, torque and routing records, component certificates mapped to requirements. <strong>Pre-verify<\/strong> the vehicle-level unknowns, EMC and braking behaviour above all, in an engineering session. <strong>Book and pass<\/strong> the formal inspection, then register. Programmes that follow this order report approval timelines in weeks; programmes that invert it, building first and asking later, report timelines in seasons and budgets in multiples.<\/p><p>One more piece of judgement: keep the conversation with the inspection authority alive throughout. Authorities are not adversaries; they are the party that has seen every way a conversion can go wrong, and a technical service that knows your project from the scoping call treats the final inspection as the last step of a shared process rather than a first encounter with a stranger&#8217;s truck.<\/p><p><strong>From prototype to approved, on one campus<\/strong><\/p><p>Individual approval is the natural exit of every prototype programme on the IntegratR campus: the EMC evidence, battery documentation and integration file grow during development, so the inspection confirms what the engineering already proved.<\/p><h4>1. What is individual vehicle approval in simple terms?<\/h4><p>A certification route where the authority approves one specific vehicle after inspection, instead of approving a design for series production. It is the standard route for one-offs, prototypes and conversions.<\/p><h4>2. When is IVA better than type approval?<\/h4><p>For single vehicles or very small numbers, IVA is faster and far cheaper. Once you build more than a handful of identical vehicles per year, small series or full type approval becomes the better economics.<\/p><h4>3. Does a diesel-to-electric conversion need individual approval?<\/h4><p>In most European countries yes, or an equivalent national conversion procedure. The conversion invalidates the coverage of the original approval, and the modified vehicle must be assessed against the changed systems.<\/p><h4>4. What evidence do I need for an electric conversion IVA?<\/h4><p>Typically: high-voltage safety documentation in line with ECE R100 substance, EMC evidence based on ECE R10, braking calculations or tests for the new configuration, and updated mass and axle load data.<\/p><h4>5. Is an individually approved vehicle valid in other countries?<\/h4><p>EU individual approvals benefit from mutual recognition arrangements, but conditions can apply per country. If cross-border registration matters, check the destination country&#8217;s acceptance before choosing the route.<\/p><p><strong>ABOUT THE AUTHOR<\/strong><\/p><p><strong>IntegratR Engineering Team<\/strong><\/p><p><em>EMC &amp; e-mobility engineering, Innovatiecampus Nijmegen<\/em><\/p><p>IntegratR runs a heavy-duty EMC test facility and engineering team at the Innovation Campus in Nijmegen, the Netherlands.
