säänkestävällä

Säänkestävällä is a Finnish term form that describes a product, material, or construction designed to withstand outdoor weather conditions. The base adjective säänkestävä means weather-resistant or weatherproof, and the adessive form säänkestävällä is used in phrases such as "säänkestävällä rakenteella" to indicate that something has weather resistance in a specific context. In general usage, the concept refers to durability against rain, sunlight, temperature fluctuations, wind, snow, and humidity.

Applications and meaning. Säänkestäviä products are commonly found in outdoor furniture, electronics designed for outdoor use, architectural elements, coatings, and vehicles. The term signals that the item has been designed, manufactured, or treated to endure exposure to the elements, though it does not always imply complete waterproofing. For example, a smartphone marketed as säänkestävä may tolerate splashes or brief submersion but may not be fully waterproof in all conditions.

Standards and testing. Weather resistance is often supported by standards and testing procedures. In Europe, environmental tests for materials and products may cover temperature cycling, humidity, UV exposure, and mechanical wear. In many industries, ingress protection (IP) ratings, corrosion resistance, and UV-stability tests are used to quantify weather resistance. The designation is typically complemented by technical specifications rather than a single certification.

Materials and design considerations. Common approaches to achieve säänkestävyys include using weather-resistant plastics or metals, protective coatings (such as powder coatings or paints with anti-UV properties), sealants, and corrosion-resistant fasteners. Designers consider climate, exposure, maintenance needs, and lifecycle costs when labeling a product as säänkestävä.

Etymology and related terms. Säänkestävä derives from sää (weather) and kestävä (durable). Related terms include säänkestävyys (weather resistance) and säänkestävyydellä or säänkestävyydellä käytettävä (describing usage with weather resistance).
