17、gdom. BS EN 16051-1:2012EN 16051-1:2012 (E) 4 Introduction The process of inflating a floating leisure article should be considered in two ways: a) the device for inflating the product, a pump; b) the compatibility between the pump and the valve or valves on the product itself. This standard, EN 160
18、51, is in two parts and addresses the performance, safety requirements, durability and test methods that should be applied to the pump and the compatibility between a pump and the device to be inflated to ensure that the inflation process can be conducted efficiently and safely. Unless a device is s
19、upplied and sold with a pump, by the manufacturer, where it is reasonable to expect the pump to be compatible with the product, there is generally a requirement to have an adaptor between a pump and the device valves to ensure that the air hose or other connector fits into or onto the valves on the
20、device. This part of the standard, Part 1, addresses the requirements for valves and where necessary, adaptors to ensure good fit and mechanical efficiency when inflating the device. 1 Scope This document specifies the valve side interface geometry between valves and pump adapters as well as strengt
21、h requirements of valves and valve adapters for inflatable consumer articles (see definition in 3.1). This document does not apply for valves of personal flotation devices according to EN ISO 12402; diving accessories and buoyancy compensators according to EN 1809. This document excludes the followi
22、ng valve types: valves used for bicycles and vehicles; needle valves (e. g. valves used for team sport balls). 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated reference
