SAE J903 Standard
At VISEE, we believe that the highest quality is not a promise, but a commitment. That’s why we don’t rely on general claims, but on measurable, objective standards. Every wiper leaving our factory must meet the rigorous requirements of the international quality standard SAE J903.
What is the SAE J903 standard?
It is a standard developed by the Society of Automotive Engineers – a global authority in automotive engineering, whose guidelines are used by the world’s leading manufacturers. This standard defines precise, extreme testing conditions for wiper blades, simulating thousands of hours of operation in the toughest environments — from heavy rain and severe frost to intense UV radiation.
What do SAE J903-compliant tests mean for VISEE wiper users?
Compliance with the standard is not just a technical term — it’s a real guarantee of your safety. To illustrate this, imagine that during a single test our wipers:
- Perform at least 500,000 operating cycles.
- Travel over 1,000 kilometers across the windshield.
- Remove an amount of water equivalent to the capacity of three large tanker trucks.
- Clean a surface area equal to two passenger airplane runways.
By choosing VISEE wipers, you gain:
Half a million operating cycles is a test that simulates years of intensive use in the toughest conditions. Thanks to this, you can be sure that our wipers are designed for maximum durability and wear resistance.
Tests in extreme temperatures and resistance to chemical factors (e.g., windshield washer fluid) give you confidence that the wiper blade will maintain its flexibility and effectiveness both during summer heatwaves and winter frosts.
Instead of marketing promises, we provide you with solid, measurable evidence. The SAE J903 standard is your peace of mind and assurance that at a critical moment — during a sudden downpour or snowstorm — VISEE wipers will ensure perfect visibility because they were built to meet exactly these challenges.
What do we measure and how do we test?
At one of our specialized testing stations — the VISEE PERFORMANCE ANALYZER (VPA 0.02 CNC) — we simulate the actual operation of wipers across a working angle range from 0 to 90 degrees. Tests are conducted in three operating modes: slow, medium, and fast, according to the cycles described in the SAE J903 standard.
The wiper’s contact pressure against the windshield surface is automatically set and programmed based on the selected blade length, allowing for precise replication of real operating conditions for a specific vehicle model.
The VISEE PERFORMANCE ANALYZER (VPA 0.02 CNC) enables advanced durability and functional tests in accordance with SAE J903, as well as experimental tests beyond the standard, under controlled conditions. In particular, it allows for:
- Replicating real working conditions of wipers (angle, speed, pressure, windshield wetting).
- Programming and automating fatigue tests (up to 500,000 cycles).
- Operating in dry/wet modes with recording of friction force, noise, and side effects (e.g., jerking).
