Product Liability • every manufacturer has a responsibility for damage and injuries that a product causes to people and property • this responsibility may be transferred to the importer • the liability may lead to payments for damages or other legal consequences MATS231 Week 07 PLA-RCD.ppt
Product Liability • the product should be systematically and carefully scrutinised to determine what damage it may cause • documentation of product development in respect of safety is important • insurance companies will demand this documentation before covering the risk MATS231 Week 07 PLA-RCD.ppt
Product Liability • before PLA: those affected had to prove that the damage had been caused by negligence on behalf of the manufacturer or distributor • now: the burden of proof is on the manufacturer to demonstrate product safety considerations were integrated into design and production MATS231 Week 07 PLA-RCD.ppt
Product Liability • Three types of defects that incur liability • design defects • exist before the product is manufactured • manufacturing defects • occur during the construction or production • defects in marketing • improper instructions and failures to warn consumers of latent dangers in the product.

The CE mark • The official marking required by the European Community for all Electric- and Electronic equipment that will be sold, or put into service for the first time, anywhere in the European community. • It proves to the buyer -or user- that this product fulfills all essential safety and environmental requirements as they are defined in the so-called European Directives. The CE markings directive (93/68/EEC) was adopted in 1993. It amends 12 other directives. • The CE-directive gives a detailed description of the initials CE and any other marks specific to a particular directive and the ways conformity may be acquired. • The CE-mark must be put on the equipment, it's size must be 5 mm (0.2") or larger. MATS231 Week 07 PLA-RCD.ppt
The CE mark • In return for fulfilling the CE marking requirements,the manufacturer or its agent gets the opportunity to cover the entire European market using only one approval procedure for the topics covered in the miscellaneous directives. • The member states of the EC cannot refuse any electronic or electrical product that has been CE marked (unless fraud suspected). • For some products however, national regulations may exist, as long as the topics covered in these national regulations are not covered by a pan-European Directive. An example is Ergonomics in Germany for PC-related equipment. MATS231 Week 07 PLA-RCD.ppt
The CE mark • The manufacturer needs however: • be European, • or have an official department in the European Community, • or have an official agent or representative that is willing to take the liability for the CE-marking. • The CE mark is sufficient to allow exporting to all EC members • There are some restrictions left over for language variations in user documentation, notably safety instructions should be in the language of the country you are exporting to. • The attachment of the CE mark to your product MUST be founded on a Compliance statement of the manufacturer or importer.

Recreational Craft Directive • The Recreational Craft Directive (94/25/EEC) Design and construction of boats from 2.5m to 24m hull length plus specified components. • Published in Official Journal L164 (30 June 1994) • In force 16 June 1996 (transition ends 15 June 1998) • Implemented in the UK by the Recreational Craft Regulations 1996 (SI 1996:1353) MATS231 Week 07 PLA-RCD.ppt
Recreational Craft Directive The Directive does not apply to: • craft intended solely for racing • canoes, kayaks, gondolas and pedalos • surfboards and sailboards • historical replicas • submersibles • hovercraft and hydrofoils • craft intended to be crewedand to carry passengers for commercial purposes(these are covered by another directive). • craft built for use by the builder are also excluded provided they are not subsequently placed on the market for at least five years. MATS231 Week 07 PLA-RCD.ppt
Recreational Craft Directive • Particular items of equipment are also covered • ignition-protected equipment for inboard and stern drive engines • start-in-gear protection devices for outboard engines • steering wheels, steering mechanisms and cable assemblies • fuel tanks and fuel hoses • prefabricated hatches and portlights. MATS231 Week 07 PLA-RCD.ppt
Recreational Craft Directive • Administration requirements • the product be marked with the CE logo • the manufacturer compile a file of technical information • In the case of complete craft or hulls, this file is to include test reports or calculations demonstrating that the craft has adequate stability in the anticipated sea conditions. The manufacturer also has to complete a Declaration of Conformity. • the Directive also lays down requirements for type testing by a notified body and/or quality control procedures • no special provision for used craft • as such it is impossible for second hand craft to comply • used craft cannot be CE marked and therefore cannot be legally imported into the EEA MATS231 Week 07 PLA-RCD.ppt
