product liability1
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 liability2
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 liability3
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 liability4
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.

Safety factors
  • BS 4994:1987 (FRP vessels and tanks)

    • The factor 3 is constant and allows for
      • materials strength reduction due tolong-term loading (even in air)

the ce mark
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 mark1
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 mark2
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.

  • 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).

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
