This European Standard specifies the rules of design, type testing, fabrication and inspection control of portable fireextinguishers manufactured with metallic bodies as far as pressure risk is concerned.This part applies to portable fire extinguishers of which the maximum allowable pressure PS is lower than or equal to 30bar and containing non-explosive, non-flammable, non-toxic and non-oxidising fluids.This European Standard also applies to the metallic gas cartridge of a volume less than 0,12 l (see Annex E) and givesguidance for sound engineering practice for metallic gas cartridges equal to or greater than 0,12 l and less than 0,5 l, seeAnnex F.This European Standard does not apply to carbon dioxide fire extinguishers.NOTE Annex A gives the classification of the different parts forming the portable fire extinguisher.

This document specifies the safety, construction and performance requirements for manually operated taps and pre-setting taps intended for use with gas appliances and similar use, hereafter referred to as "taps".This document is applicable to taps with declared maximum inlet pressures up to and including 50 kPa (500 mbar) of nominal connection sizes up to and including DN 50 for use with one or more fuel gases in accordance with EN 437.This document is not applicable to:a) manual operated shut-off valves conforming to EN 331;b) controls which use auxiliary energy (e.g. electrical energy supplied externally);c) an assessment of the control regarding Performance Level (PL) and Safety Integrity Level (SIL).

This European Standard specifies safety requirements for construction, performance, sizing and marking for swimming devices intended to assist users with movement through the water in the early stages of water awareness, while learning to swim or while learning part of a swimming stroke. It also gives methods of test for verification of these requirements.This part 2 of EN 13138 applies only to class C devices that are designed to be held in the hands or by the body. Typical devices include kick boards and pull/kick boards. These devices are used to assist in learning to swim or to assist with swimming strokes and improving specific elements of the stroke, which have either inherent buoyancy or can be inflated.It does not apply to pull buoys, swim rings, lifebuoys, buoyancy aids, lifejackets or aquatic toys.

This part 3 of EN 13138 specifies safety requirements for design, sizing, materials, strength and in-water performance as well as provisions for marking and the information supplied by the manufacturer for swim seats. It also specifies the relevant test methods. This standard is not applicable to products covered by EN 13138 1 and 2.This part 3 of EN 13138 applies only to devices into which the user is placed and which have either inherent buoyancy or can be inflated or a combination of both. It only applies to class A devices intended to introduce the user to the water environment. These devices are only intended for children aged up to 36 months with a body mass less than or equal to 18 kg. It does not apply to class B or class C devices, to pull buoys, lifebuoys, buoyancy aids, lifejackets or aquatic toys.

This European Standard specifies safety requirements for construction, performance, sizing, marking and information supplied by the manufacturer for swimming aids intended to assist beginners with movement through the water while learning to swim or while learning part of a swimming stroke. It also gives methods of test for verification of these requirements.This part 1 of prEN 13138 applies only to devices that are designed to be worn, to be securely attached to the body and which have either inherent buoyancy or can be inflated. It only applies to Class B devices intended to introduce the user to the range of swimming strokes. It does not apply to Class A or Class C devices, to pull buoys, swim rings, lifebuoys, buoyancy aids, lifejackets or aquatic toys.This document (prEN13138-1:2018) applies only in connection with prEN 13138-4:2018.

This document specifies the characteristics of single-pole circuit breakers, temperature compensated with a rated current from 1 A to 25 A, used in aircraft on-board circuits at a temperature between -55 °C and 125 °C and at an altitude of 15 000 m max.These circuit breakers are operated by a push-pull type single push button (actuator), with delayed action "trip-free" tripping with a polarized signal contact which is open when main contacts are closed, and inversely.They will continue to function up to the short-circuit current.

This document specifies a method of measuring the tensile properties of stranded conductors, strands, solid conductors and braids.When required, it can be used also on finished cables.It is intended to be used together with EN 3475-100.

This document specifies the characteristics of three-pole circuit breakers, temperature compensated with a rated current from 1 A to 25 A, used in aircraft on-board circuits at a temperature between -55 °C and 125 °C for ratings = 15 A and -55 °C to 90 °C for ratings > 15 A and at an altitude of 15 000 m max.These circuit breakers are operated by a push-pull type single pushbutton (actuator), with delayed action "trip-free" tripping.They will continue to function up to the short-circuit current.

This document specifies the characteristics of UV laser printable multicore jacketed electrical cables for use in the on-board electrical systems of aircraft at operating temperatures between -55 °C and 200 °C.It is also possible to mark these cables with qualified compatible markings. These markings are supposed to be in accordance with EN 3838.

Shall be according to EN 203 1:2019, with the following addition:This European Standard applies to commercial gas heated fryers.

This document specifies requirements and tests for the construction, performance and safety of class 1,5 Capillary Thermal-Mass Flow sensor gas meters (hereinafter referred to as meter(s)). This applies to meters having co-axial single pipe, or two pipe connections, that are used to measure volumes of fuel gases of the 2nd and/or 3rd family, as given in EN 437:2018.In general, the term "thermal mass flow meters" applies to a flow-measuring device using heat transfer to measure and indicate gas flowrate, as defined in ISO 14511.NOTE 1 Although the word "mass" is present in the definition of the measurement principle, gas meters covered by this document provide measurement of gas at base conditions of temperature and pressure.These meters have a maximum working pressures not exceeding 0,5 bar and a maximum flowrate not exceeding 160 m3·h-1 over a minimum ambient temperature range of -10 °C to +40 °C and a gas temperature range as specified by the manufacturer with a minimum range of 40 K.This document applies to meters indicating volume at base conditions, which are installed in locations with vibration and shocks of low significance. It applies to meters in:- closed locations (indoor or outdoor with protection, as specified by the manufacturer) with condensing humidity or with non-condensing humidity; or, if specified by the manufacturer:- open locations (outdoor without any covering) both with condensing humidity or with non-condensing humidity;and in locations with electromagnetic disturbances likely to be found in residential, commercial and light industrial use.For meters which indicate unconverted volume reference can be made to Annex C.Unless otherwise stated, all pressures given in this document are gauge pressures.Requirements for electronic indexes, valves and additional requirements for batteries incorporated in the meter and any other additional functionalities are given in EN 16314:2013.Unless otherwise stated in a particular test, the tests are carried out on meters that include additional functionality devices intended by the manufacturer.Clauses 1 to 13 are for design and type testing only.
