The “Volvo STD 418-0002 Windshield washer fluid for initial filling and after-sales” standard developed by the Volvo vehicle company describes the requirements for concentrated windshield washer fluids intended to be used in windshield washing cycles after diluting with water.
All aftermarket products with the Volvo group brand (Volvo, Renault or other) must be verified in accordance with this standard. For approval of the windshield washer fluid, suppliers must submit a complete inspection report showing that the product complies with all the features specified in this standard, along with a sample of the windshield washer fluid.
This standard replaces the STD 1283-15 standard and the Renault D41-01-003 standard developed by the French automobile company Renault.
Meanwhile, all products manufactured by Volvo are subject to Volvo's internal health and environmental assessment according to the STD 900-0008 standard. This assessment covers all products used in Volvo facilities and all chemical products sold by Volvo as spare parts. Each product accepted in this evaluation is given its own Volvo part number. The assessment must comply with the national legislation of each country in which it will be used.
The product is generally intended to be mixed with demineralized water in the proportions specified by the supplier to obtain different freezing points according to season or regional needs.
The composition of the concentrate should be as follows:
Physico-chemical property requirements are included in the table provided in the standard. Accordingly, ASTM D1177-17 for freezing point, ASTM D1287-11 for pH value, ISO 304 and ASTM D1331-14 for surface tension, ASTM E203-01 for water content and ISO 12185 and ASTM D4052-22 for density are taken as basis.
The washer fluid must effectively remove all types of traffic film, dirt and insects without causing any cloudiness. In addition, the washing liquid must be miscible with itself and other washing liquids available on the market.
The washing liquid must not cause any damage to adjacent or underlying materials or adversely affect their functionality. The ingredients included should not discolour the container or the paint. The compatibility of the washing liquid with the paint is tested on relevant parts or representative test panels. Washing fluid intended for use in extremely cold conditions is used for these tests. 2-K polyurethane topcoat, water-based topcoat and 2-K polyurethane varnish are used for testing. In these tests, Volvo STD 1026-8177 Chemical resistance – Swelling standard and Volvo STD 1026-8177 Chemical resistance – Color change standard are taken into account.
Washing fluid must not damage or adversely affect the function of adjacent or underlying materials. The ingredients included should not discolour the container or the paint. These tests used extremely cold wash liquid product and natural rubber, ethylene propylene diene terpolymer and ethylene propylene diene terpolymer + polypropylene. In these tests, Volvo STD 412-0001 Rubber standard and Volvo STD 422-0004 Painting of organic surfaces standard are taken into account.
