Status of Leitlinien:
The PED Guidelines are not a legally binding interpretation of the Directive. The legally binding text remains that of the Directive. However, the PED Guidelines represent a reference for ensuring consistent application of the Directive. They represent, unless indicated differently in the respective guideline text, the unanimous opinion of the Member States

15.03.2016 There is a contradiction between the requirements in article 4 paragraph 1 (d) and those in Annex II point 3. Can pressure accessories be classified as “article 4.3” as indicated in the tables in annex II or must all of them satisfy the essential requirements as indicated in article 4 paragraph 1 (d) ?
15.03.2016 The Directive uses the notion of DN (defined in Article 2 (11) for the classification of piping or piping accessories (cf. Article 3 paragraph 1(c)). How to apply the Directive for classifying the tubular products or accessories for which the notion of DN does not exist (copper tubes, plastic valves, pressure regulators, hollow sections…)?
15.03.2016 How should vessels and piping for superheated water be classified?
08.01.2016 Which type of pressure equipment is a heat exchanger ?
08.01.2016 Some warm water generators having a volume greater than 2 L are intended to generate water at a temperature less than 110 °C, but are fitted with a safety temperature limiter which is set to a temperature of 120 °C. What value of maximum allowable temperature, TS, shall be declared by the manufacturer?
15.03.2016 How should fired or otherwise heated equipment be classified if a fluid other than water is being heated?
15.03.2016 How should a vessel which is intended to contain water below 100 °C be classified when there is a marginal gas cover?
08.01.2016 Which pressure and volume values must be used to determine the category of vessels used as gas-loaded accumulators, or other vessels with a flexible or non fixed membrane, given that these are made up of two chambers with different fluids?
08.01.2016 If a vessel contains a fluid which meets the conditions of the introductory paragraph to Article 4, paragraph 1(a)(i) (e.g. air) and a liquid which meets the conditions of the introductory paragraph to Article 4, paragraph 1(a)(ii) (e.g. water) - how shall the vessel be classified?
15.03.2016 When is it possible for a manufacturer to apply a module from a higher category and what are the consequences?
15.03.2016 For warm water boilers which are controlled by a temperature thermostat and protected by a safety temperature limiter, does the maximum allowable temperature (TS) mean:
a) the maximum intended operating temperature under normal conditions as controlled by the thermostat; or;
b) the temperature setting of the ultimate over-temperature safety device i.e. the limiter?
08.01.2016 How can manufacturers use Article 4 paragraph 1 to determine the appropriate conformity assessment Tables in Annex II?
08.01.2016 Article 4 paragraph 1(a)(i) second indent, states that all portable extinguishers must comply with the essential safety requirements (ESRs) and be assessed according to Annex II, Table 2. In addition, Table 2 states that portable extinguishers must exceptionally be classified at least in category III. To what parts of a portable extinguisher do these requirements apply?
15.03.2016 Does the classification of the pressure cookers in category III for the assessment of the design mean that also the essential safety requirements are linked to category III?
15.03.2016 Are pressure regulators safety accessories in the sense of PED?
08.01.2016 How are pressure accessories classified?
08.01.2016 Article 14 paragraph 3 states that a manufacturer may choose to apply one of the conformity assessment procedures which apply to a higher (conformity assessment) category, if available. Does this mean that a manufacturer of pressure equipment covered by Article 4 paragraph 3, referred to as Sound Engineering Practice (SEP), can choose to apply Module A for example and hence apply a CE Marking?
20.06.2016 Do two housings, designed to contain fluids under pressure and which have a common boundary (e.g. separating wall), constitute two vessels, or two chambers of the same vessel and what requirements apply to such an item of pressure equipment ?
