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.

A method to calculate viscosity and other properties, excluding density, for use in the metering ofnatural gas flow

This part of ISO 16486 specifies the physical and mechanical properties of pipes made from unplasticized polyamide (PA-U) in accordance with ISO 16486-1, intended to be buried and used for the supply of gaseous fuels. It also specifies the test parameters for the test methods to which it refers.ISO 16486 is applicable to PA-U piping systems the components of which are connected by fusion jointing and/or mechanical jointing.In addition, it lays down dimensional characteristics and requirements for the marking of pipes.Pipes conforming to this part of ISO 16486 are jointed typically by using mechanical, electrofusion or butt fusion (see Annex A) techniques, but not by solvent cement jointing.

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.

This document specifies terms and definitions for different PVC based materials used for the production of unplasticized polyvinylchloride (PVC-U) profiles for windows and doors.It describes the content and meaning of post-consumer and post-industrial recyclate as it is used in new products. It distinguishes between different PVC recepies used in production for PVC window and door profiles.This document shall serve as the reference standard for definitions used in related standards such as all parts of EN 12608, EN 17410 or standards for PVC based profiles for building applications.

This standard applies to lanyards intended to be the primary connection between the climber and the belaystance.NOTE: lanyards intended only for positioning are not covered by this standard (e.g. daisy chain).

This document specifies general safety requirements and test methods for all pieces of gymnastic and sports equipment and for all pieces of equipment for the use of physical education, training and competition, intended for use supervised by a competent person and not specified in other, individual standards and/or federation rules.
