These system standards are distinguished from system standards for conventionally installed plastics piping systems by the requirement to verify certain characteristics in the as-installed condition, after site processing. This is in addition to verification of characteristics of plastics piping systems as manufactured. These system standards are complemented by the information contained in ISO/TR 11295 [6] and EN 13689 [1] (listed in the bibliography). The system standard EN 14409 comprises five parts, as follows:
— Part 1: General — Part 2: Lining with continuous pipes — Part 3: Lining with close-fit pipes (this document) — Part 4: Lining with cured-in-place pipes — Part 6: Lining with inserted hoses The requirements for any given renovation technique family are covered by Part 1: General, and are for use in conjunction with the relevant other part. For example, for the requirements relating to "Lining with close-fit pipes", it is necessary to refer to both parts 1 and 3. A consistent structure of clause headings has been adopted for all parts to facilitate direct comparisons across renovation technique families. Figure 1 shows the common part and clause structure and the relationship between EN 14409 and the system standards for other applications. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom.
