GB/T 20064.1-2023 Reciprocating internal combustion engines - Handle starting equipment - Part 1: Safety requirements and tests
1 Scope
This document specifies requirements for handle starting equipment used on reciprocating internal combustion engines for land, rail and marine use, excluding engines used to propel road vehicle and aircraft.
This document may be applied to engines used to propel road construction, earth moving machines and for other applications where no suitable International Standards exist.
In addition to the technical safety requirements, this document describes procedures for checking adherence to these requirements.

3 Terms and definitions
For the purposes of this document, the following definitions apply.
3.1
handle starting system
starting system using a crank handle to rotate the engine up to the required firing speed
3.2
automatic disengagement device
device which automatically releases the connection between the engine and the starting handle once the engine is running, thus preventing the handle from being turned by the engine
3.3
guide
that part of the handle starting system which guides the starting handle during starting and prevents its being thrown out after disengagement
3.4
kick back limiter
that part of the handle starting system which, when used in accordance with the instructions and when maintained correctly, prevents or limits the kick back travel to such an extent as to avoid the risk of injury
3.5
kick back
sudden change of direction of rotation of the starting handle, caused by compression or combustion pressure of the engine during starting procedure
3.6
disengagement travel
circumferential distance which the grip of the starting handle travels from the point of its change of rotational direction to its disengagement from the starting shaft, measured at the centre of the grip
3.7
angle of disengagement
angle through which the shank of the starting handle turns from the point of change of rotational direction to its disengagement from the starting shaft
3.8
kick back travel
distance which the grip of the handle travels from the point of its change of rotational direction until it comes to the rest, measured at the centre of the grip
3.9
kick back angle
angle through which the shank of the starting handle turns from the point of its change of rotational direction until it comes to the rest
4 Other regulations and requirements
4.1 For engines used on board ships and offshore installations which have to comply with rules of a classification society, the additional requirements of the classification society shall be observed. If this applies the name of the classification society shall be stated by the customer prior to placing the order.
For engines which do not require such classification, any additional requirements shall in each case be subject to agreement between the manufacturer, supplier and customer.
4.2 If special requirements from regulations of any other authority, e.g. inspecting and/or legislative authorities, have to be met, the authority shall be stated by the customer prior to placing the order.
4.3 Any further additional requirements shall be subject to agreement between the manufacturer, supplier and customer.
