What is ISO 23308-1 about?  
ISO 23308-1 specifies general test criteria and requirements to measure the energy consumption for self-propelled industrial trucks (hereinafter referred to as trucks) during operation. For electric trucks, the efficiency of the battery and the battery charger is included.
Note1: ISO 23308-1 is applicable to the in-use phase of the product life cycle.
Note2: ISO 23308-1 applies to the following truck types according to ISO 50531:
- Counterbalance lift truck, Articulated counterbalance lift truck
- Reach truck (with a retractable mast or fork arm carriage)
- Straddle truck, Pallet-stacking truck
- Pallet truck, Platform and stillage truck
- Pallet truck end controlled, Order-picking truck
- Centre-controlled order-picking truck
- Towing, pushing tractor and burden carrier
- Towing and stacking tractor, Side-loading truck (one side only)
- Variable-reach container handler
- Counterbalance container handler, Lateral-stacking truck (both sides)
- Lateral-stacking truck (three sides), Multi-directional lift truck.
Who is ISO 23308-1 for? 
 The content of ISO 23308-1 is of relevance for the following stakeholder groups:
- Machine manufacturers (small, medium and large enterprises)
- Market surveillance authorities
- Machine users (small, medium and large enterprises)
- Service providers, e.g. for consulting activities. 
Why should you use ISO 23308-1?  
 The ISO 23308 series deals with the energy efficiency of industrial trucks including batteries and battery chargers. Energy efficiency is important for both environmental reasons as well as economic reasons. ISO 23308-1 contains the procedures to determine the efficiency of trucks, traction batteries, and battery chargers. The other parts provide a specific test cycle for different truck types. ISO 23308-1 specifies guidelines to test the energy efficiency of industrial trucks. ISO 23308-1 also helps to check for the battery efficiency of industrial trucks.
To determine the overall energy consumption of electric trucks the test in ISO 23308-1 considers:
- The overall efficiency of the truck, including motor (s), controller(s) and electrical installation
- The efficiency of the battery/batteries
- The efficiency of the battery charger
