# Commission Delegated Decision (EU) 2015/1959 of 1 July 2015 on the applicable systems to assess and verify constancy of performance of wastewater engineering products pursuant to Regulation (EU) No 305/2011 of the European Parliament and of the Council (Text with EEA relevance), Annex II: SYSTEMS OF ASSESSMENT AND VERIFICATION OF CONSTANCY OF PERFORMANCE

Extent: E+W+S+N.I.

For the products covered by this Decision, taking into account their essential characteristics, the systems for assessment and verification of constancy of performance apply as follows:
Table 1
For all essential characteristics except reaction to fire

Table 2
For reaction to fire only
For all products indicated in the first column of Table 1, the systems for Assessment and Verification of Constancy of Performance are determined, depending on their subfamilies, as follows:
Product subfamilies
Applicable systems for assessment and verification of constancy of performance as set out in Annex V to Regulation (EU) No 305/2011
Products for which a clearly identifiable stage in their production process results in an improvement of their reaction to fire performance (e.g. by adding fire retardants or limiting organic materials)
1
Products for which an applicable European legal base exists to classify their reaction to fire performance without testing
4
Products not belonging to the subfamilies indicated in rows 1 and 2
