The Blue Guide 2022 also indicate that “Unless otherwise specified in specific legislation, instructions and safety information need to be provided (114), whether the product is intended for consumers or other end-users. This should include all the necessary information for the safe use of the product, to enable the consumer to assemble, install, operate, store, maintain, and dispose of the product.” Following the Blue guide, “As a rule, the [technical] documentation has to include a description of the product and of its intended use and cover the design, manufacture and operation of the product.”, and “Intended use means the use for which a product is intended in accordance with the information provided by the manufacturer (or importer) placing it on the market, or the ordinary use as determined by the design and construction of the product.”
