4 The authorities in (a), (b) and (c) require that any testing or certification in terms of this Recommended practice, be done by an approved test laboratory (ATL). This Recommended practice should be read in conjunction with SANS 10108. Annexes A and C form an integral part of this Recommended practice. Annex B is for information only. Introduction The approving authorities and the Explosion Prevention Industry, represented by the SOUTH african Flameproof Association, agreed that information pertaining to statutory product conformity requirements, including approved STANDARDS , approved inspection authorities, approved testing bodies, and approved certification bodies, will be made publicly available by means of this Recommended practice, and that any changes to the lists will be made known through amendments to this Recommended practice. The Chief Inspector of Mines of the Department of Minerals and Energy has undertaken to accept responsibility for the accuracy and the updating of this Recommended practice and STANDARDS SOUTH AFRICA will promptly publish any changes received from the Department of Minerals and Energy.

Regulatory requirements for explosion-protected apparatus 1 Scope This Recommended practice deals with product conformity requirements for explosion-protected apparatus used in SOUTH AFRICA . It should be read in conjunction with SANS 10108. NOTE SANS 10108 covers the classification of hazardous locations in terms of the possibility of fire or explosion owing to the presence of flammable gases, vapours, dusts or fibres in the air, and also gives the selection criteria for apparatus suitable for safe use in such locations, called explosion-protected apparatus. 2 Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of this Recommended practice. All normative documents are subject to revision and, since any reference to a normative document is deemed to be a reference to the latest edition of that document, parties to agreements based on this Recommended practice are encouraged to take steps to ensure the use of the most recent editions of the normative documents indicated below.
