- Classes of use / classes of use or of risk
- UNE-EN 351-1 defines the concept of class of use as the likelihood that a structural element will sustain attacks by biotic agents, and primarily is a function of the extent of damp it comes to reach during its life of service. The following classes of use are defined below.Class of use 1: The structural element is covered, protected from the elements and not exposed to moisture. Under these conditions, solid wood has a moisture content below 20%. Examples: beams or pillars inside buildings;Class of use 2: The structural element is covered and protected from the elements, but, given the environmental conditions, wood moisture content over 20% in part or in the entirety of the structural element may occasionally occur. Examples: structure of a covered swimming pool where high environmental moisture is maintained with occasional condensation and structural elements near water conduits;Class of use 3: The structural element is exposed and not in contact with the ground. The moisture content of wood can exceed 20%. It is split into two classes;Class of use 3.1. The structural element is outdoors, above the ground and protected, that is, subject to design and construction measures aimed at impeding excessive exposure to the direct effects of the elements, inclement atmospheres or sources of damp. In these conditions, wood moisture content can at times exceed 20%. Examples: beam that points outdoors, but in its upper zone and head is protected by a capstone or sacrifice pieces.Class of use 3.2: The structural element is located outdoors, above the ground and is not protected. In these conditions wood moisture frequently exceeds 20%. Examples: any element whose upper face or head is subjected to the direct action of rainwater, a pillar that, without being embedded in the ground, maintains a shorter distance with this and is splashed by rain or subjected to snow piling up, etc.Class of use 4: The structural element is in contact with the ground or with fresh water and, therefore, exposed to humidification, where the moisture content permanently exceeds 20%. Examples: constructions on fresh water and pillars in direct contact with the ground;Class of use 5: Situation in which the structural element is in permanent contact with salt water. In these circumstances, the moisture content of the wood is permanently over 20%. Example: constructions in salt water.
