Vehicle material survey
Identification of relevant materials, components, installation locations, suppliers and available technical evidence.
Regulatory Engineering Support
UN R118 Material Documentation Support
Engineering support for identifying, organising and tracing the interior materials used in buses, minibuses and coaches during flammability-related approval preparation.
Preparation Objective
Every relevant vehicle material must be identifiable and traceable
Interior trim, insulation, flooring, seat materials, curtains, plastics, cables and other installed materials may require supporting technical evidence. Missing supplier data or unclear material references can delay testing and approval preparation.
A test report is useful only when it matches the installed material
Product name, manufacturer, composition, thickness, mass per unit area, construction and installation location must be consistent across the vehicle, supplier declaration and supporting test documentation.
Service Scope
Material identification, evidence review and document control
Support can begin during material selection, prototype construction or preparation of an existing vehicle for an approval project.
Material classification
Organisation of materials according to their type, construction, application, location and required project documentation.
Supplier document review
Review of declarations, datasheets, certificates and test reports for consistency with the material used in the vehicle.
Gap identification
Identification of missing, expired, incomplete or technically inconsistent material documentation.
Test-sample preparation support
Coordination of sample definition, supplier information, dimensions, orientation and traceability inputs requested for testing.
Approval-package preparation
Organisation of material lists, installation locations, evidence, photographs and supporting technical records.
Typical Material Groups
Materials and components reviewed during preparation
The final material scope must be established for the actual vehicle, its construction and the requirements accepted by the responsible authority or technical service.
Wall, roof and interior trim materials
Thermal, acoustic and engine-compartment insulation
Floor coverings, underlayers and related adhesives
Seat upholstery, foam and seat-cover materials
Curtains, blinds and flexible interior materials
Plastic covers, panels and moulded interior components
Cable insulation, conduits and electrical protective materials
Air ducts, hoses and flexible system components
Adhesives, coatings and multi-layer material combinations
Material variants introduced by suppliers or vehicle derivatives
Project Workflow
From vehicle material survey to a controlled evidence package
Survey
Installed and planned materials are identified with their locations and suppliers.
Classify
Materials are grouped by type, construction, application and evidence requirement.
Verify
Supplier data, material references and available reports are checked for consistency.
Close gaps
Missing documents, supplier questions and potential test needs are coordinated.
Compile
Material lists and supporting evidence are organised for project submission.
Project Outputs
Traceable material data for approval preparation
Material master list
Structured records covering material description, supplier, reference, construction and installation location.
Evidence-status matrix
Clear identification of available, missing, incomplete or inconsistent technical documents.
Supplier action list
Required declarations, technical clarifications, samples and supporting documents for each open material.
Documentation package
Organised material lists, datasheets, reports, declarations, photographs and location information.
TLG SYSTEMS provides material identification, document review and
preparation support. Testing, formal interpretation, certification and
approval decisions remain under the authority of the appointed
laboratory, technical service and responsible approval body.
