Introductory note
1. For the preparation of EN 50272-2 the following European country’s national standards have
been taken into consideration:
Germany: DIN VDE 0510 Part 2
Batteries and battery installations
United Kingdom: BS 6133 for lead-acid batteries
BS 6132 for NiCd batteries
Sweden: SS 408 01 10 relating parts for rechargeable batteries,
erection and ventilation
Switzerland: SEV 1000-1 and SEV 1000-2 relating parts of instructions
for installations in buildings
Italy: Doc. D.P.R. 547, art. 302 and 303 ,
Safety in battery installations
CEI 21-6 Part 3
Netherlands: NEN 1010 relating parts of safety regulations for low voltage
installations
Austria ÖVE-C10 Part 2 ,
Batteries and battery installations
France NF C15-100 , article 554
Batteries d‘accumulateurs
Article EC10, Règlement de securité contre l‘incendie relatif aux
établissemments recevant du public
Only those paragraphs have been considered where common agreement was found or specific
need was recognised.
2. The described safety requirements comprise the protective measures to protect from hazards
generated by the electricity, the electrolyte, and the explosive gases when using secondary
batteries. In addition measures are described to maintain the functional safety of batteries and
battery installations.
3. For the electrical safety (protection against electric shock) under clause 5 this document refers to
HD 384.4.41 (IEC 60364-4-41). The pilot function of this standard is fully observed by indication
of cross-reference numbers of the relevant clauses. But interpretation is given where adoption to
direct current (DC) circuits is required.
4. This safety standard comes into force with the date of publication and applies to all new batteries
and battery installations. Previous installations shall conform with the existing national standards
at the time of installation. In case of redesign of old installations this standard applies.

4 General definitions
4.1 (secondary) cell; (rechargeable) cell; single cell
An assembly of electrodes and electrolyte which constitutes the basic unit of a secondary
battery. (see IEC 60050-486-01-02)

4.3 valve regulated (secondary) cell
A secondary cell which is closed under normal conditions but has an arrangement which allows
the escape of gas if the internal pressure exceeds a predetermined value. The cell cannot
normally receive addition to the electrolyte. (see IEC 60050-486-01-20)
4.4 gastight sealed (secondary) cell
A secondary cell which remains closed and does not release either gas or liquid when operated
within the limits of charge and temperature specified by the manufacturer. The cell may be
equipped with a safety device to prevent dangerously high internal pressure. The cell does not
require addition to the electrolyte and is designed to operate during its life in its original sealed
