Mae'r datganiad hwn yn rhoi diweddariad pellach i Aelodau ynghylch profion system gyfan a gynhaliwyd gan y Sefydliad Ymchwil Adeiladu (BRE) yn dilyn argymhellion gan Banel Arbenigwyr Llywodraeth y DU a sefydlwyd yn sgil trychineb Tŵr Grenfell. Roedd fy natganiadau ysgrifenedig ar 28 Gorffennaf a 3 Awst yn sôn am ganlyniadau'r prawf cyntaf a'r ail brawf.

Mae rhagor o ganlyniadau bellach wedi'u rhyddhau gan yr Adran Cymunedau a Llywodraeth Leol; canlyniadau sy'n ymwneud â phrofion 3 a 4\. Mae'r profion fel a ganlyn:

1. Prawf 3: ACM â llenwad polyethen arafu tân (categori 2 mewn profion sgrinio), ac insiwleiddiad sbwng polyisocyanurate; a
2. Prawf 4: ACM â llenwad polyethen arafu tân gydag insiwleiddiad gwlân mwynol (categori 2 mewn profion sgrinio).

Bu i Brawf 3 fethu'r prawf system gyfan, gan y bu i ledaeniad y fflamau ymestyn yn uwch nag offer y prawf. Mae canlyniad y prawf yn dangos bod y system hon wedi methu â bodloni'r meini prawf a nodir yn BR 135 fel sy'n ofynnol yn ôl y canllawiau cyfredol ar Reoliadau Adeiladu. Caiff prawf pellach, sef y seithfed prawf, ei ychwanegu at yr amserlen i ddilyn y pumed a’r chweched prawf, a hynny er mwyn rhoi darlun mwy cyflawn, gan brofi ACM â llenwad polyethen arafu tân (categori 2 mewn profion sgrinio) gyda insiwleiddiad sbwng ffenolig.

Mae'r system ym Mhrawf 4 yn debyg i'r cyfuniad sydd ar bedwar adeilad sy'n berchen i Ddinas a Sir Abertawe. Mae samplau o'r rhain wedi'u profi'n flaenorol gan y BRE. Pasiodd y system a brofwyd y prawf, ac mae hynny'n ddatblygiad cadarnhaol. Wrth gwrs, rhaid i landlordiaid a pherchenogion barhau i fanteisio ar bob cyngor a chanllaw arbenigol sydd ar gael iddynt mewn perthynas â'u hadeiladau.   
  
Byddaf yn parhau i roi'r wybodaeth ddiweddaraf i Aelodau wrth i'r drefn brofi fynd rhagddi.

Caiff y datganiad ei gyhoeddi yn ystod y toriad er mwyn rhoi'r wybodaeth ddiweddaraf i aelodau. Os bydd aelodau eisiau i mi wneud datganiad pellach neu ateb cwestiynau ynglŷn â hyn pan fydd y Cynulliad yn dychwelyd, byddwn yn hapus i wneud hynny.

This statement provides a further update to members on whole\-system tests undertaken by the Building Research Establishment (BRE) following recommendations by the UK Government Expert Panel established in the aftermath of the Grenfell Tower disaster. My written statements of 28 July and 3 August referred to the first test and second test results.


Further results relating to tests 3 and 4 have now been released by the Department for Communities and Local Government. These relate to:


1. Test 3: ACM with a fire retardant polyethylene filler (category 2 in screening tests), and Polyisocyanurate (PIR) foam insulation; and
2. Test 4: ACM with a fire retardant polyethylene filler with mineral wool insulation (Category 2 in screening tests).


Test 3 failed the whole system test, due to the flame spread extending above the test apparatus. The test result shows that this system failed to meet the criteria set out in BR 135 as required by the current Building Regulations guidance. A further, seventh, test will now be added to the schedule to follow the 5th and 6th tests. This is intended, to give a more complete picture, testing ACM with fire retardant polyethylene filler (category 2 in screening tests) with phenolic foam insulation.


The system in Test 4 is similar to the combination in place on 4 buildings owned by the City and County of Swansea, samples of which had previously been tested by the BRE. The tested system passed the test, which is a positive development. Of course, landlords and owners must continue to draw on all expert advice and guidance in relation to their individual buildings.


I will continue to update members as the testing regime continues.


This statement is being issued during recess in order to keep members informed. Should members wish me to make a further statement or to answer questions on this when the Assembly returns I would be happy to do so.
