| Periodic Safety Inspection Station | Mandatory or periodic roadworthiness inspection for vehicles already in operation. | Passenger cars Buses Trucks Trailers Motorcycles | Brake tester, headlamp tester, side-slip tester, suspension or axle-load equipment where applicable, exhaust-gas analyzer, vehicle-lift or pit inspection tools, and underbody visual-inspection equipment. | GB 38900 for motor-vehicle safety inspection methods and technical requirements; GB 7258 for basic motor-vehicle safety technical conditions. | Usually local or regional; availability depends on the approved inspection network and local licensing arrangements. | High Multiple inspection lanes are common at larger stations; actual throughput depends on lane count, staffing, and appointment controls. | Valid operating authorization, calibrated measuring instruments, documented inspection procedures, qualified inspectors, traceable records, and consistent handling of non-conforming vehicles. |
| Emission Inspection Facility | Measurement of exhaust emissions for in-use vehicles and compliance screening. | Gasoline vehicles Diesel vehicles Heavy-duty vehicles Alternative-fuel vehicles | Five-gas analyzer or equivalent gasoline-emission equipment, diesel opacity or particulate-measurement equipment, dynamometer where required, OBD communication tools, sampling systems, and environmental monitoring devices. | GB 18285 for gasoline-vehicle emission testing; GB 3847 for diesel-vehicle emission testing; applicable local environmental-management requirements. | Generally city or regional, with broader coverage where connected to an approved inspection network. | High Designed for repeated standardized testing; capacity is affected by lane configuration and the proportion of diesel vehicles. | Equipment calibration certificates, zero-span checks, environmental-condition records, OBD data integrity, controlled sampling procedures, and documented quality-control results. |
| Type-Approval and Conformity Testing Center | Development, certification support, and conformity testing for new vehicle models, systems, and components. | Passenger vehicles Commercial vehicles Electric vehicles Components | Chassis dynamometer, climatic chamber, electromagnetic-compatibility equipment, crash or restraint-system facilities where approved, battery and electric-powertrain test systems, brake and handling instrumentation, and data-acquisition systems. | Applicable GB and GB/T vehicle standards, relevant compulsory-certification or type-approval requirements, and project-specific technical specifications. | National or multi-region project coverage; testing is commonly scheduled in advance. | Medium High technical depth but lower routine throughput because test programs are longer and more customized. | ISO/IEC 17025 laboratory competence, validated test methods, uncertainty evaluation, engineering review, controlled configuration management, and internationally recognized technical reporting practices. |
| Independent Accredited Automotive Laboratory | Third-party verification, failure analysis, performance testing, and supplier or product-quality evaluation. | Vehicles Components Batteries Materials Electronic systems | Environmental chambers, vibration and durability rigs, electrical safety analyzers, battery abuse and performance systems, material-analysis tools, dimensional equipment, noise and vibration instruments, and customized test rigs. | Contract-specific GB, GB/T, ISO, IEC, or UNECE methods, together with internally validated procedures when no single mandatory method applies. | Can serve domestic and international projects, subject to scope, accreditation, and laboratory authorization. | Medium Capacity varies widely because custom engineering and laboratory scheduling are usually required. | Published accreditation scope, method validation, proficiency-testing participation, measurement traceability, impartiality controls, technical peer review, and reproducible raw-data packages. |
| Fleet and Commercial-Vehicle Inspection Provider | Scheduled compliance, preventive checks, roadworthiness monitoring, and maintenance decision support for large vehicle fleets. | Logistics fleets Buses Construction vehicles Special-purpose vehicles | Portable diagnostic scanners, brake and tire inspection tools, axle-load measurement, lighting testers, exhaust analyzers, telematics data review, lifting equipment, and structured visual-inspection checklists. | GB 7258, GB 38900, applicable commercial-vehicle regulations, fleet-maintenance procedures, and customer-specific safety rules. | Usually site-based or multi-site within a province or logistics region; mobile inspection may be available. | High Suitable for recurring fleet programs; capacity is normally measured by vehicles inspected per shift or per scheduled visit. | Fleet-level inspection records, repeatability statistics, defect classification, escalation procedures, inspector training records, and auditable corrective-action tracking. |
| Electric and New-Energy Vehicle Safety Laboratory | Battery, high-voltage system, charging, thermal, electrical-safety, and post-incident assessment. | Battery-electric vehicles Plug-in hybrids Fuel-cell vehicles Battery packs | Battery cyclers, insulation-resistance testers, high-voltage safety equipment, thermal chambers, environmental test systems, charging analyzers, battery-management-system interfaces, thermal-event monitoring, and data-acquisition equipment. | Applicable Chinese GB and GB/T requirements for electric vehicles, traction batteries, charging systems, electrical safety, and thermal protection; project-specific standards may also apply. | National project capability is possible, but specialized equipment and safety controls should be verified for each site. | Low to Medium Usually lower throughput because tests can be long-duration, destructive, or subject to strict high-voltage safety controls. | High-voltage safety authorization, emergency-response procedures, calibrated sensors, thermal-event controls, battery traceability, independent technical review, and complete raw-data retention. |
