What is BS EN 1175 about?
BS EN 1175 specifies the electrical requirements for the design and construction of the electrical installation in self-propelled industrial trucks that are within the scope of ISO 5053-1, except variable reach trucks as defined in ISO 5053-1:2015, 3.21 and 3.22, straddle carriers as defined in ISO 5053-1:2015, 3.18, and 3.19, and specific functions, parts, and/or systems utilized for the automatic operation of driverless industrial trucks as defined in ISO 5053-1:2015.
The machinery concerned and the extent to which hazards, hazardous situations, or hazardous events are covered are indicated in the scope of BS EN 1175.
BS EN 1175 does not deal with hazards that could occur:
- During construction
- When operating in potentially explosive atmospheres
- Because of malfunction of non-electric safety-related parts of control systems, e.g., hydraulic and pneumatic elements like pistons, non-electric valves, pumps, etc.
Note 1: Reference is made to this document in other standards which cover the non-electrical requirements of the various industrial truck types.
Note 2: The level of the defined required performance for electrical safety-related control systems can be used as a guideline to determine the performance of non-electric systems.
Note 3: Hazards due to penetration of water and dust are covered by the definition of PLr of safety functions, according to EN ISO 13849-1.
Who is BS EN 1175 for?
BS EN 1175 is of relevance for the following stakeholder groups representing the market players about machinery safety:
- Machine manufacturers
- Health and safety bodies
- Machine users
- Service providers
Why should you use BS EN 1175?
BS EN 1175 deals with safety requirements for all electrical and electronic components of industrial trucks, including electrically actuated hydraulic/pneumatic valves.
BS EN 1175 specifies minimum performance levels required for safety functions realized by safety-related parts of control systems. BS EN 1175 is intended to be used to avoid or minimize hazards or hazardous situations. These situations can arise during the operation in use for which it is designed and during maintenance of trucks in accordance with the specifications and instruction given by the manufacturer.
BS EN 1175 provides the electrical/electronic and safety-related parts of control system requirements for those self-propelled industrial trucks identified above to complete the requirements in the relevant part of the EN ISO 3691 and EN 16307 series of documents.
What’s changed since the last update?
BS EN 1175:2020 supersedes BS EN 1175‑1:1998+A1:2010, BS EN 1175‑2:1998+A1:2010 and BS EN 1175‑3:1998+A1:2010, which are withdrawn. The main changes compared to the previous EN 1175 series are:
- Applicability to both internal combustion engine and electric battery-driven industrial trucks
- Definition of the PLr for safety functions of the control system
- Design specifications for safety-related parts and control systems
- Specific safety requirements for Li-ion energy sources
- Rules for the design of the electric/electronic assistance systems
