Report of the EGOLF TC1 meeting held on 13th October 2014 at RIFS in Minsk

1 Opening of the meeting The chair of TC1, Rupert Ehrlenspiel, welcomed members to the meeting and expressed appreciation to RIFS for hosting the week of EGOLF meetings.

2 To approve the draft agenda, N561rev1 The agenda was approved, subject to addition of proposal for course on cable test methods (N545) which would be dealt with under Item 7 Harmonisation Courses.

3 To approve the report of the previous meeting held on 20th March 2014, N557 The report was approved.

4 To consider any matters arising

- EGOLF working group: Uncertainty of measurement in the SBI Further to discussions following last meeting, BAM have informed the Secretary General (SG) that they do not have the resources at the present time to organise a workshop on UoM in the SBI. Hendrik Rademacher has offered to hold the workshop instead at MPA NRW in Dortmund. The SG will check with Bart Sette at wfrgent that he is still able and willing to make a presentation. H Rademacher will then contact him to agree dates and exchange ideas for development of the workshop, prior to preparation of announcement and registration form which it is hoped will be circulated early in the New Year. Actions SG/H Rademacher/B Sette

5 To note discussions on reaction to fire matters in CEN/TC127/WG4 No meeting of WG4 has been held since last EGOLF meeting. The next meeting will be chaired by Silvio Messa on 5th November. H Rademacher reported that comments on prEN 16733:2014 (Reaction to fire tests for building products - Determination of a building products propensity to undergo continuous smouldering) will be the main item on the agenda. Mr Messa has also confirmed that EGP 01 on revision of EN ISO 1182 - non combustibility test method will be discussed at that meeting. The SG will send a reminder. Action SG

1 6 Helpdesk reports 2012 and 2013, N495rev4 and N548rev1 Helpdesk reports are available on the TC1 Helpdesk Forum. These are for note except for the following items:

- helpdesk 2013-07 EN 11925-2 and FEF pipe insulation. Action is brought forward to provide solution for attention of SH02, so that the Sector Group can propose recommendation to CEN TC 127 (Eric Rasmussen, chair TC88 thermal insulation products) Action H Rademacher

- helpdesk item 2012-19 SBI test and range of colours when testing HPL or other kinds of product. The chair of TC1 clarified that reference to "3" repeats" in solution given should read "2" repeats and that a formal recommendation is required. Since there are other topics related to colour which need to be reviewed, Philip Howard offered to undertake this task and then combine solution for 2012-19 with the recommendation for coatings (ER 34rev1). Action P Howard

7 Harmonisation courses The course catalogue is regularly updated on the “Activities” page of the EGOLF website. The next series of RtoF courses had to be postponed due to late cancellation of delegates. This caused problems for remaining participants who had paid for their flights and accommodation. It is suggested that, in future, course providers impose a cancellation fee so that courses can go ahead with less than the required minimum number of trainees. This will be discussed during Plenary meeting.

The RtoF series is now scheduled to take place from 16th to 20th February 2015. A course given in German on “External fire exposure to roofs with burning brands tm1” is being held today and tomorrow at Prüfinstitut Hoch. This will be followed by courses on tm2 at SP, Sweden, on 11th November and on tm1 at Kiwa BDA, Netherlands, on 12th November.

Gaiker RtoF videos The SG will ask Gaiker if they would be prepared to make available on "You Tube" their excellent video presentations of the SBI test, the non-combustibility test, the bomb calorimetric test, the small burner test and the flooring radiant panel test. Action SG

New proposal: course on cable test method in EN 13501-6, N545 Four labs. have responded positively to the question circulated by SG about interest in attending this course; four raised their hands at this meeting to confirm they perform the cable test method and Marek Łukomski reported that eight delegates at a recent course hosted by ITB on EN 13381-1 and -8 had confirmed their interest. Further to recommendation of Executive, Marek will seek sponsorship for development of course from industry (e.g. Europacable) on condition that the course fees and copyright are not compromised so that individual manufacturers and labs. pay the full set of fees. Action M Łukomski

8 Reaction to fire round robins

2 - Report of RR on CEN/TS 1187:2012 tm1 and tm2, N571 (Powerpoint presentation) and N543 and N559 (full confidential and public summary reports) Anne Steen-Hansen presented the conclusions of this RR (see N571) which had demonstrated very good results. Hendrik Rademacher observed that, following his check of damaged EPS insulation used in this round robin, he had found some strange test results which he has captured in document N570 and which demonstrate that it was not possible, due to the CaSi-substrate used in the tests, for fire penetration to be observed. Consequently, the statement concerning reproducibility needed to be revised since all samples in all labs. had passed the test.

Anne responded that, regarding the penetration of substrate, the results had been treated as reported from the laboratories (as in a real test for a customer). It was agreed that many labs. had not interpreted their results correctly and that, according to the standard, the deck should be treated as part of the test specimen. Clarification is therefore required (e.g. through the EGOLF harmonisation course).

Albert Hameete agreed to draft an EGOLF recommendation and forward this for the attention of CEN TC 127 WG5, requesting that a sentence be added to the standard stating that the supporting layer is part of the test specimen. In parallel, Anne will make a simple revision to the RR report and add an instruction to Annex D (Test Instructions).

Lab. numbers referred to in the concluding remarks of document N570 are advised to check their test results carefully. Actions A Hameete/A Steen-Hansen/participating labs. RR TS 1187

Melted or burned material, N569 Hendrik Rademacher had made use of the photos from CEN/TS 1187 RR in order to check the values of damaged lengths after the test (tm1). Although some labs. had not provided photos showing EPS after the test and others had not used glass fibre sheet between the PVC sheet and EPS insulation, he was nevertheless unable to prove there was no damage and recommended that more trials be carried out by other labs. so that, with the benefit of further experience, EGOLF would be able to decide what is burned in EPS tests.

After some discussion it was agreed that photos will always be subjective and that what is required is a definition of melted and burned with EPS, taking into account the definition of pyrolysis. Albert Hameete agreed to draft a position paper containing his suggestions as to how to resolve the problem. No decision would be taken but the paper would be forwarded for the attention of CEN TC 127 WG5. Action A Hameete

Anne asked participating labs. to check their own results in the draft RR report and send any comments to the SG no later than 13th November. The final report would be published at the end of next month. Action RR participating labs./A Steen-Hansen

3 Draft Recommendation - use of brands in tm1 of CEN TS 1187, N566 It is very important for brands to be prepared by trained technicians. A recommendation is given in N566 which will be discussed at the next meeting. Action SG – agenda item March 2015

4 - RR with test to EN ISO 9239-1 The draft report will be ready for meeting in March. Action wfrgent/SP Fire Research

- Future RR on SBI test Since MPA Bau Hannover and BAM do not currently have the resources to progress this RR, which will involve a test mainly with wallpaper on gypsum board, alternative labs. are sought to organise the RR and undertake analysis of results. (Post meeting note: SP and MFPA Leipzig have kindly volunteered to lead on this RR with assistance from SP Fire Research to carry out analysis of results. A proposal will be prepared in time for Executive in January and Spring meetings of EGOLF). Action M Andersson/N Neumann

9 Standards on Reaction to Fire: update CEN TC 127 work programme, N562 & N564 These papers are for note. Now that EGOLF is a formal liaison partner of CEN TC 127, a detailed and regularly updated work programme will be available to EGOLF.

10 Publications: Recommendations and position papers EGR 81 (classification report based on testing to CEN/TS 1187 tm1) and EGR 82 (EN 13823 flaming droplets and particles) are available on EGOLF publications folder of website.

Revised draft position paper CEN/TS 1187 tm1: testing on standard wood particle board deck, N553rev This paper will remain on TC1 meetings folder for four weeks pending comment and then it will be published as a formal position paper and forwarded to CEN TC 127 for attention of WG5. Action SG

11 Technical matters brought forward for consideration

11.1 Helpdesk items for note only The Chairman confirmed that items to be raised for discussion at meetings of TC1 should be posted to the Helpdesk Forum at least two weeks before a meeting.

Members agreed also that, in order to discuss helpdesk items fully, it was necessary for a representative from the lab. which had raised the question to be present. For this reason, outstanding items in document N554rev1 (CEN/TS 16459:2013 Roofing Group) and question raised by Niall Rowan on behalf of wfrgent would have to be postponed. For note: TC1 members

EN 13823 – SBI substrate and calcium silicate boards The Chairman had recently posted a reply to this question. He encouraged labs. with other answers to add a thread to the forum. Action TC1

11.2 2013-05 PIR and PUR flat and linear products classification EN 13501-1 N531rev2

5 The insulation product group (SG19) had provided the SG with a clear answer to this helpdesk item. The product standard has to be changed and following sentences added: A flat product shall be tested as a flat product. A linear product with a diameter > 300 mm shall be tested as a flat product. A linear product with a diameter ≤ 300 mm shall be tested as a linear product. The SG will prepare a draft recommendation which will be uploaded to the meetings folder for four weeks' comment prior to publication. Action SG

11.3 Revised EGR61 – how to test loose fill insulation – reply from CEN/TC 88 This revised recommendation had been discussed briefly at meeting of SG19 on 25th September and will be brought to the attention of WG15 in context of EN 15101 on 27th November.

The SG was asked to rearrange bullet points so that reference to seven metal wires comes first and the blowing process becomes the fourth bullet point. (Post meeting note: The Chair has also offered to add wires to figure 1 once original drawing is available). The EGR will then be uploaded for a further four weeks for comment prior to formal publication. At their meeting on 25th November, SH02 will be asked to produce a position paper for attention of the product standard committee SG15. Actions R Erhlenspiel/SG

11.4 2014-04 - application rules for flexible sheets, N567 It was difficult to comprehend the explanation given here. Hendrik Rademacher attempted to simplify the product into a two-layer product - a composite product with a substantial layer and a flexible sheet. If a test has been made then the lab. must prove that the classification is no better than declared. The Chairman reported from a test series performed by TUM with a very rigid plastic sheet with a thickness of 4 mm and 8 mm in the SBI. As required in CEN/TS 15117 they retested a 6 mm thick plastic sheet which obtained the worst FIGRA of the three thicknesses. He therefore proposed to include only a thickness tolerance of +- 15%, not more. The outcome of discussions is that it cannot be allowed to vary the thickness as proposed in the Helpdesk. If this recommendation is needed by wfrgent who raised the question, they are requested to redraft and circulate it again. Action wfrgent

11.5 2014-05 SBI – application rules for insulation, N568 For these systems (combustible products shielded by other products), rules often do not exist for euro-classification and no product standards are applicable because of the combination of products and specific mounting set-ups. The chairman emphasized that e.g. air gaps or meltable products inside a multi-layered system may cause unforeseeable effects. After some initial discussion, Members agreed with the Chairman that these issues were extremely complicated and that EGOLF is not in a position to propose rules. It may, however, be possible to discuss this further with direct involvement of wfrgent who raised the helpdesk items. It might be helpful if wfrgent provides examples or less abstract proposals, so that discussions could begin with concrete cases. Action wfrgent

6 11.6 2014-06 SBI- LFS of corrugated metal hoses, N565 It was observed that the SBI test procedure in the product standard EN 14800 is not suitable, since the product is hardly touched by flames and does not reach the far edge of the furnace and that an alternative test procedure should be developed. In response to the helpdesk question, lateral flame spread is when the flames reach the farthest end of the hose if the end of the hose is located within the zone between a height of 500 and 1000 mm. If the end of the hose lies above the 500/1000 mm zone, lateral flame spread will occur if the flame reaches the 1000 mm line.
