دور EN 81-20
EN 81-20 addresses safety rules for the construction and installation of lifts, including requirements affecting passenger and goods-passenger lifts. It is used as a key technical reference in European lift projects.
دور EN 81-50
EN 81-50 covers design rules, calculations, examinations and tests of lift components. In practice, EN 81-20 and EN 81-50 are considered together when engineering and validating compliant lift systems and components.
ما الذي يجب أن يطلبه مشترو المشاريع؟
Request clear technical specifications, drawings, component information, certificates or declarations where applicable, and documentation identifying the standards used in the proposed system. The exact conformity route depends on the product and market.
لا تتعامل مع المعيار كملصق للمنتج
Compliance is a system and conformity matter. A supplier should be able to explain which requirements apply to the specific lift, component or project rather than simply placing a standard number in a brochure.
