Pressure gauges are pressure accessories within the meaning of PED Article 2, paragraph 5, which may be covered by CE marking for high pressure (see table below).
Remark 1: Pressure gauges are not safety accessories within the meaning of PED Article 2 paragraph 4.
Remark 2: A pressure gauge may possibly be regarded as a protective device within the meaning of PED Annex I, point 2.10 b.
Remark 3: The conformity assessment categories for vessels with a volume ≤ 0,1 litre cannot be determined from PED annex II tables 1, 2, 3 and 4 because the tables are not specified for volumes < 0,1 litre.
Remark 4: If a pressure gauge has a volume ≤ 0,1 litre, and a value of PS above the limits defined in PED Article 4 paragraph 1, then the vessels must satisfy the essential safety requirements of Annex I.
Table: Classification of pressure gauges (low volume-high pressure accessory):
| Table in Annex II | Service | Classification (Volume ≤ 0,1 litre) | Classification (Volume ≤ 0,1 litre) |
|---|---|---|---|
| 1 | Gas Fluid Group 1 | PS ≤ 200 bar SEP1 | PS > 200 bar Essential Safety Requirements Annex I applies CE-Marking |
| 2 | Gas Fluid Group 2 | PS ≤ 1000 bar SEP1 | PS > 1000 bar Essential Safety Requirements Annex I applies CE-Marking |
| 3 | Liquid Fluid Group 1 | PS ≤ 500 bar SEP1 | PS > 500 bar Essential Safety Requirements Annex I applies CE-Marking |
| 4 | Liquid Fluid Group 2 | PS ≤ 1000 bar SEP1 | PS > 1000 bar Essential Safety Requirements Annex I applies CE-Marking |

- The conformity assessment categories for pressure gauge with a volume ≤ 0,1 litre cannot be determined from Tables 1, 2, 3 and 4 because the Tables are not specified for volumes < 0,1 litre. However, Article 4 paragraph 1 together with Article 4 paragraph 3 can be used to determine which pressure gauge must satisfy the essential safety requirements and those that must be designed and manufactured according to the Sound Engineering Practice (SEP) of a Member State.
- If a pressure gauge has a volume ≤ 0,1 litre, and a value of PS above the limits defined in Article 4 paragraph 1, then the pressure gauge must satisfy the essential safety requirements of Annex I.
- In the absence of specific information in the Tables of Annex II for the conformity assessment of pressure gauge described in point 2 above, the manufacturer may choose any module‚ or single combination of modules, set out in PED section 1 of Annex II.
