A school-bus wiper specification must be reviewed for the vehicle category, destination market and complete installation. This page is a procurement checklist, not a declaration that a LEILI component or a vehicle has obtained a particular approval.
Establish the applicable requirements
Ask the vehicle manufacturer or approval specialist to identify the market, vehicle category, applicable regulations and revisions, and which party is responsible for system validation. Record these inputs in the project specification. Do not transfer a requirement from a different country or vehicle category without checking its scope.
Keep glazing and wiper evidence separate
UN Regulation No. 43 concerns safety glazing materials and their installation. A reference to that regulation alone is not proof of wiper-system compliance. Review each approval or test document against its actual subject and scope.
Source for the scope of UN Regulation No. 43: UNECE official regulation text. Check the applicable revision and approval requirements for the destination market.
Review the complete visibility system
| Area | Evidence to request |
|---|---|
| Wiping arrangement | Windshield geometry, mounting points, sweep and parking layout in the agreed drawing. |
| Electrical integration | Supply, controls, parking function, harness and connector information. |
| Washer arrangement | Reservoir, pump, tubing and nozzle configuration where included in the project. |
| Environmental validation | Model-specific reports and installation conditions required by the project. |
| Release | Agreed sample checks, responsibilities and production drawing revision. |
Verify documents against the supplied configuration
Check the legal entity, document number, issue or expiry information where applicable, product identification, standard edition and test configuration. A quality-management certificate, an environmental test report and a vehicle approval serve different purposes. Do not use one as a substitute for the others.
Create an acceptance record
Agree the checks with the vehicle manufacturer before ordering. Record the sample or installation identification, drawing revision, checks performed, results and any deviations requiring action. Quantitative limits should come from the applicable specification and competent engineering review, not a generic blog table.
Information to include in an enquiry
State the destination market, vehicle category, intended application, windshield and mounting information, electrical supply, quantity, and the approval or test documents requested by the vehicle project. LEILI can review the component configuration; project-specific approval responsibilities must be agreed separately.
Send the information needed for a technical review
Send installation photographs, the LEILI model if known, measured dimensions or a drawing, electrical supply and quantity. LEILI model numbers identify our own products or layout references; they are not OE-number cross-references. Contact LEILI for a configuration review.
