<s>[INST] The next text is a question of a member of the European parliament:"The issuing of the European technical specification prEN 14351‑1 concerning windows and doors is creating considerable uncertainty among joiners in Belgium.  The standard lays down what tests have to be performed to ensure that the end product is ‘safe’. The CEmark guarantees conformity with the standard. Both financially and organisationally, however, it is hardly feasible for businesses in this sector — in many cases micro-enterprises which mainly provide made-to-measure products — to develop prototypes and conduct the relevant tests on them.  As the Commission indicated in reply to a previous parliamentary question concerning the impact of standardisation on small joiners, Guidance Paper M provides a solution to this problem. According to the interpretation of the Construction Products Directive given in that document, test results may be shared (point4.13, p.14: shared ITT results). The result of one test then applies to all businesses in the industry, for example businesses affiliated to the same professional association.  This question concerns the status of Guidance Paper M and falls into three parts.  1.In the interests of legal certainty, Ishould be interested to hear from the Commission whether Guidance PaperM still remains in force after the entry into force of the standard. The standard itself makes no reference to the guidance paper.  2.Can the Commission confirm that test results as referred to in point4.13 of Guidance PaperM may be shared between businesses in such a way that they accord with the harmonised standard?  3.What is the precise legal status of Guidance Paper M?"
