3 WG1 Installation outside building structures of flexible piping systems New convenor: Peter Verlaan (NL) CEN / TS (Validated design parameters design of buried thermoplastics piping systems). Major change to structure during revision, draft sent for TC 155 committee vote in Oct Comments to be addressed and document issued for public comment. WG1 asked TC 155 if they should deal with a guidance for installation of infiltration systems for storm water management (see notes under WG26) and whether there is a need for guidance for above ground installation of non-pressure drainage and sewerage (agreed that there is no evidence of need). Next meeting 21st Jan WG13 Systems with structured wall pipes for nonpressure drainage and sewerage PE, PP, PVC-U Convenor: Peter Verlaan (NL) EN (Structured-wall piping systems of PVC-U, PP and PE). Parts 1 (General requirements and performance characteristics), 2 (Type A) and 3 (Type B) revisions are ready for CEN enquiry and Formal Vote (early 2015). Main focus large diameter pipes, test regime and editorial changes. WG 13 asked TC 155 request an early revision of CEN/ TS (assessment of conformity), because of the introduction of very large diameters and new test methods in other parts. Request noted for future meeting. Next meeting April 2015 (date to be confirmed following CEN enquiry).

PVC-U, PP and PE). Revised following comments during 5 year review. Ready for CEN enquiry between Dec 2014 and Mar Part 1 will also need to be revised to remove overlap. TC 155 were asked about the timescale for this activity and it was referred to WG20. Decision on harmonized standards under mandate M/118 pending TC 155 discussions on M/131. Next meeting 9th/10th June 2015 WG 26 Systems for storm water handling Convenor: Hielke Hoekstra (NL) WI and WI (see below for titles), will run out of time before completion, new work items approved by TC 155 to continue work. WI (Test method for determination of short term compression strength of boxes). Document being checked ahead of 2nd committee ballot. WI (Test method for determination of long term structural compression strength of boxes). Proposed test needs revision as the outcome of the test results will not give distinctive results. UK delegation working on revision to present to next meeting. WI (Specification for boxes used for infiltration, attenuation and storage systems made of PVC-U and PP). In preparation, but disagreement of materials clauses. UK propose including in informative annex to guide suppliers and purchasers of materials. Preliminary work item registered by TC 155 for components for storm water handling to cover mechanical resistance of tanks. This addresses infiltration and infiltration tanks referred from TC 165 / WG50 (water reuse). New part for Attestation of Conformity will be started when product standard has gone to CEN enquiry. Next meeting 9th / 10th February

5 WG17 Rehabilitation of pipeline systems Convenor: Wim Elzink (NL). The scope of WG17 was recently aligned with ISO TC 138/SC8 (chaired by John Gumbel, UK) to include trenchless replacement and renovation, SC8 lead on standards development and includes both water and gas applications. Wim Elzink is liaison officer between TC 155 and ISO TC 138/SC8. Concern was raised at TC 155 over marginal difference between rehabilitation (pipe in pipe) and no-dig installation of new pipes (replacement by a new pipe) and where responsibilities lie. Next meeting - none planned. WG25 Recycling of PVC-U, PE and PP materials Convenor: Tinus De Lange (NL). Nothing to report. Next meeting - none planned. WG 27 Environmental aspects Convenor: Sándor Aranyi (Hungary). Drafts for Environmental Product Declarations - Product Category Rules for (i) buried pipes and (ii) pipes in buildings to be sent to TC 155 for committee ballot before CEN enquiry. AHG 45 Lifetime expectancy of non-pressure piping systems Convenor: Henk Meerman (NL) This AHG is working on a package of tests for determining the life expectancy of materials of nonpressure pipes to increase options for use of recycled materials. Two tests considered: Fatigue and Cracked Round Bar method based on ISO/DIS Comparative testing between two tests on PP and PVC, virgin and non-virgin is ongoing to establish method and equipment. Next meeting 2nd / 3rd December CEN TC 107 Prefabricated district heating piping systems Fpr CEN/TS crosslinkable PE-Xb in district heating pipes to be cancelled. CEN TC 127 Fire safety in buildings draft EN 1366 includes plastic pipes, to be issued for CEN enquiry.

CEN / CLC TC 213 Underground plastics conduits for protection of cables - new standard being drafted EN (part 1 for pulled cables, part 2 for other cable installation). TEPPFA project on lifetime of polyolefin non-pressure pipes conclusions presented to TC 155, slides will be circulated later. Needs to link with work of AHG CEN TC 164 Water Supply 4MS Portugal to join as 5th member. Substances already listed for food contact automatically to be accepted for water and not included in core 4MS list. Test for mutual recognition of Enhancement of Microbial Growth not agreed but until M/136 restarted for products there is no driver to sort this. National Regulations continue. CEN TC 165 Wastewater systems EN 124 (Gully, manhole tops) prepared for FV includes Part 6 for thermoplastics; EN 1610 (pipelaying) prepared for FV; EN (trenchless construction) withdrawn. EN 1433 (drainage channels) revision started but plastics not well represented. ISO TC 138 and its working groups see separate report e-doc 6248 for work in ISO.

6 CEN TC 155 PLENARY MEETINGS Spring 2015: Vienna, Austria Autumn 2015: Delft, Netherlands Spring 2016: Helsinki, Finland Mandate M/131 (harmonised standards on pipes, tanks and ancillaries not in contact with water intended for human consumption) Four application-based harmonised standards (hens) proceeding: pren Buried and above ground piping components for nonpressure soil and waste discharge within the building structure. pren Non-pressure drainage and sewerage piping components buried in ground. pren Buried and above ground piping components for water under pressure. pren Hot and cold water piping components. The draft hens were subject to a 5 month CEN enquiry following which the tasks groups have started to discuss comments. CEN TC 155 sought a meeting with the European Commission s DG Enterprise to confirm fundamentals of CE marking under the CPR, clarify essential requirements and to identify a way forward. This document is prepared as an overview of the workings of CEN TC 155 for BPF-PPG members only. Reference should always be made to the full documents and official minutes and resolutions of the meeting. All information is given in good faith but no responsibility can be accepted for errors and omissions. DG Enterprise has proposed that CE marking for this sector may be reviewed as products standards already exist to meet CPR objective to remove barriers to trade. Other mandates under Construction Products Regulations Mandate M/136 Harmonised standards for construction products in contact with water intended for human consumption work on products postponed (confirmed by DG Enterprise), response to mandate to be delayed. Mandate M/366 Dangerous substances nothing to report. Mandate M/118 Harmonised standards for waste water engineering products work on manholes and shafts pending clarification of direction of M/131.
