Pressure Equipment Regulations, 2009

Regulation 9 - Pressure Equipment Marking


(1) Every manufacturer of pressure equipment shall cause the pressure equipment to be marked in accordance with the relevant health and safety standard incorporated into these Regulations under section 44 of the Act.


(2) Every manufacturer shall cause a data plate to be permanently fixed in a conspicuous place to any steam generator or pressure vessel with the following minimum particulars:
(a) Name of manufacturer;
(b) country of origin;
(c) year of manufacture;
(d) manufacturer’s serial number;
(e) reference number, date and edition of the health and safety standard;
(f) design pressure in units of Pascal;
(g) design temperature for both minimum and maximum in degrees Celsius;
(h) capacity in cubic metres;
(i) unique mark of an approved inspection authority as applicable; and
(j) the hazard category in accordance with the requirements of SANS 347.


(3) In the case of composite pressure equipment the following information shall be included in addition to that referred to in subregulations (2):
(a) The resin system of the corrosion barrier/lining;
(b) the resin system of the structural wall; and
(c) the name and specific gravity of the medium for which the vessel was designed.


(4) No person may remove a marking or data plate referred to in these Regulations or wilfully damage or alter the particulars marked thereon, except as provided in these Regulations.


(5) A user shall ensure that any modification that changes the original design conditions is identified by affixing an additional data plate.


(6) A user shall ensure that a data plate is affixed to any steam generator or pressure vessel that has been re-certified: Provided that where the manufacturer is unknown, the user responsible for the re-certification shall be deemed to be the manufacturer.




(a) For imported pressure equipment not meeting the Pressure Equipment Regulations marking requirements, the importer shall affix an additional data plate containing the missing or correct information. The additional data plate does not need to reference the importer.
(b) The AIA shall verify compliance to the PER for Category II and higher imported pressure vessels, steam generators and assemblies. The AIA shall stamp the additional data plate required by PER to indicate that the AIA was involved with the conformity assessment review and shall countersign the conformity assessment review certificate.
(c) Re-certification of a steam generator and pressure vessels may only be undertaken as per the proposed Annexure A of SANS 347. Re-certification of transportable gas containers is as per SANS 10019.
(d) Equipment that has been re-rated to operate at different design conditions shall be verified by an AIA.
(e) Pressure equipment other than steam generators and pressure vessels may be marked in Bar, only where regulated by the Health and Safety Standard.
(f) For very small pressure vessels where a normal sized data plate cannot be permanently fixed in a conspicuous place as stated in PER 9(2), a data plate may be affixed with a corrosion resistant metal wire to this pressure vessel or alternatively a durable sticker.
(g) Local manufactured equipment not fully compliant with ASME certification requirements must be in accordance with SANS 347 Annex C requirements.
(h) No changes or corrections shall be made on any nameplate, but through the addition of a new nameplate with only the corrected information.

(i)        For RSA/CI/OHSA certified equipment the markings in 9.(2).(e) above shall typically be:



AA = Section (VIII Division1 = 8.1)

BB = Edition (2015 = 15)

CC = Any additional markings required by ASME

(j) For imported pressure vessels and steam generators that are CE marked which reference ASME as the design standard but are not in full compliance of ASME certification mark requirements, the additional data plate shall be stamped PED/RSA/CI/OHSA-AA-BB-CC.
(k) For repairs a repair nameplate is not required even if specified by and in-service health and safety standard.
