Companies that manufacture load-bearing components (load-bearing parts) that are dimensioned with euro codes must certify themselves against EN 1090-1.
\nExecution must be done against EN 1090-2.
\nThe manufacturer then receives the CE marking of its load-bearing products.
\nThe requirement for CE marking of products covered by EN 1090-1 became compulsory on 1 July 2014. Manufacturer’s system for manufacturing control
\n(FPC system) must be certified to EN 1090-1 by a notified body, the certified manufacturer must issue a declaration of performance for the product and CE mark it.<\/p>\n
If you manufacture or assemble structural components in steel or aluminum, you are probably covered. All construction products covered by a harmonized standard (or ETA) must be CE marked. You can find a list of all harmonized standards here.<\/p>\n
EN 1090 states that the welding must be in accordance with ISO 3834. Depending on the execution class (EXC), the following level applies to ISO 3834:
\nEXC 1: ISO 3834-4
\nEXC 2: ISO 3834-3
\nEXC 3: ISO 3834-2
\nEXC 4: ISO 3834-2<\/p>\n
There are four execution classes (EXC 1-4) where 1 is the most elementary and 4 is the most advanced. It is the constructor who determines the execution class using Eurocoder.<\/p>\n
The performance classes look like follows:
\nEXC 1: Ceilings, railings, animal stalls, carport (given less than S 355)
\nEXC 2: Warehouse, office, house
\nEXC 3: Dynamic structures, bridges, really big houses,
\nEXC 4: Nuclear power, large arenas<\/p>\n
Yes, the Swedish National Board of Housing, Building and Planning and SIS have an agreement that allows you to get Euro codes free here.<\/p>\n
You can buy these at SIS – Swedish Standards Institue.<\/p>\n
ISO 5817, Quality levels for discontinuities and shape deviations on welds are purchased here.<\/p>\n
No, EN 1090 falls under something called 2+ systems where a notified body (certification body) is required.<\/p>\n
Yes, the Swedish translation “welding responsible” is a poor translation of English’s “Welding coordination”, correct translation should be “Welding coordination”. This means, for example, that you can he an IWS to handle EXC 2 jobs and an IWE that takes care of EXC 3 jobs.<\/p>\n
No, there is no formal requirement for it. If the person responsible for welding is undiplomatic then we will do a deeper interview during the audit and assess what level they are at.<\/p>\n
No, it sounds unreasonably expensive. We have certified over 200 companies and estimate that it costs from perhaps SEK 50,000 to a couple of hundred thousand swedish kronor, entirely depending on the starting position for the company and the desired EXC level.<\/p>\n
No, we are impartial and independent. We neither get nor want to do anything other than to certify finished systems.<\/p>\n
EN 1090-1 contains four different methods for CE marking.
\nZA 3.2 Geometric data and material properties (Ex. Welded beam with flanges and life)
\nZA 3.3 Declaration of components’ carrying capacity (Ex. Company with own design and turnkey contract)
\nZA 3.4 Declaration against component specification (Ex. Smith who works against drawing)
\nZA 3.5 Declaration of the component’s strength value (s) from the buyer’s order (as ZA.3.3 with additional requirements, such as a higher snow zone or the like)<\/p>\n
In the Swedish edition of 2009, ZA.3.5 has been dropped. In the current version EN 1090-1: 2009 + A1: 2001 it is included, it is bought here<\/a>.<\/p>\n The steel building institute and the Welding commission, where A3CERT is a member, have good information.<\/p>\n","protected":false},"featured_media":2775,"parent":0,"menu_order":5,"template":"","meta":{"_acf_changed":false},"class_list":["post-3495","certifieringar","type-certifieringar","status-publish","has-post-thumbnail","hentry"],"acf":[],"_links":{"self":[{"href":"https:\/\/a3cert.com\/en\/wp-json\/wp\/v2\/certifieringar\/3495","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/a3cert.com\/en\/wp-json\/wp\/v2\/certifieringar"}],"about":[{"href":"https:\/\/a3cert.com\/en\/wp-json\/wp\/v2\/types\/certifieringar"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/a3cert.com\/en\/wp-json\/wp\/v2\/media\/2775"}],"wp:attachment":[{"href":"https:\/\/a3cert.com\/en\/wp-json\/wp\/v2\/media?parent=3495"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}Where to read more about EN 1090?<\/h3>\n
