Article 1 
Objective The purpose of this Decision is to clarify the principles for the measurements of prices and volumes contained in Chapter 10 of Annex A to Regulation (EC) No 2223/96, in view of the need to further harmonise price and volume measures. The clarifications given in the present Decision, shall be used for the data transmitted to Eurostat from the first transmission of data pursuant to Regulation (EC) No 2223/96 onwards, at least for the data referring to the years 1995 and later. Article 2 Clarifications to the general principles for the measurement of prices and volumes Clarifications to the general principles that shall be followed in the measurement of prices and volumes contained in Chapter 10 of Annex A to Regulation (EC) No 2223/96, particularly as concerns the elementary level of aggregation, the choice of index formula and the choice of base year, are laid down in Part I of Annex I to the present Decision. Article 3 Classification of methods by product A classification of methods for certain types of products into most appropriate methods, alternatives which may be used if the most appropriate methods cannot be applied, and methods which shall not be used as from the first transmission of data to Eurostat pursuant to Regulation (EC) No 2223/96 onwards, is laid down in Parts II and III of Annex I to the present Decision. Article 4 Research programme For those products for which the classification of methods defined in Article 3 is not stated in Annex I to the present Decision, this classification will be defined taking into account the results of a research programme, which shall be completed by the end of the year 2000, and after decision of the SPC. Article 5 Transitional periods Transitional periods for the application of the principles as clarified in Article 2, are laid down, for each Member State, in Annex II to the present Decision. Member States may ask, in addition, for transitional periods to be granted for the application of the methods referred to in Article 3, which shall be decided at the latest by the end of the year 1998. In the case of a Member State for which a transitional period is granted, and which presents for a given year a reduction of GDP in real terms calculated according to the national methods in place, the Member State shall assist Eurostat to the fullest possible extent in evaluating the scale of the effect of any deviation from the principles contained in the present Decision. Article 6 Inventory Member States shall provide Eurostat, at the latest by the end of the year 2002, with a full inventory of procedures and basic statistics used to measure GDP in real terms and its components. The inventory shall at least cover the methods used in the final accounts. Article 7 Addressees This Decision is addressed to the Member States. Done at Brussels, 30 November 1998.
