Test Scope Definition
Identification of the intended vehicle configuration, applicable test subjects and required engineering evidence.
HOMOLOGATION · TEST PREPARATION · TECHNICAL COORDINATION
Testing & Technical Service Coordination Support
Engineering support for test preparation, technical documentation, vehicle readiness and communication with the designated technical service.
TEST READINESS
A successful homologation test begins before the vehicle arrives at the test facility
Testing requires more than scheduling a vehicle and selecting a laboratory. The applicable requirements, vehicle configuration, component approvals, technical documents, test conditions and expected evidence must be aligned before the official activity begins.
TLG SYSTEMS supports vehicle manufacturers by preparing the engineering information, following technical open items and coordinating project inputs required for efficient communication with the designated technical service.
01
Test time should be used for verification
Missing documents, undefined configurations and unresolved engineering questions should be addressed before the official test date.
SCOPE OF SUPPORT
Engineering support throughout the testing process
The exact scope is defined according to the vehicle category, approval route, applicable regulations, technical-service requirements and current project stage.
Vehicle Readiness Review
Review of the physical vehicle, installation conditions, components and configuration before testing.
Document Preparation
Organisation of drawings, calculations, component approvals, data sheets and vehicle information required for review.
Technical Question Follow-Up
Engineering assessment and structured follow-up of questions, clarifications and additional evidence requests.
Test-Day Engineering Support
Technical support for vehicle configuration checks, documentation and engineering clarification during planned test activities.
Result and Action Review
Review of observations, test results and open items requiring design, documentation or repeat-test actions.
TECHNICAL COORDINATION
Clear information between every project stakeholder
TLG SYSTEMS helps organise technical information and open items between the vehicle manufacturer, component suppliers, engineering teams and the designated technical service.

Role and responsibility
TLG SYSTEMS provides engineering, preparation and coordination support. TLG SYSTEMS does not act as an approval authority, designated technical service or certification body. Test execution, official assessment, certification and approval remain under the responsibility of the appointed technical service, approval authority, vehicle manufacturer and approval holder.
PREPARE THE PROJECT
SEND PROJECT DATA
Build a clear technical path from vehicle preparation to testing
Send the available vehicle configuration, drawings and approval information for an initial review of the required support.
