The use of swim seats does however not replicate any form of a correct swimming stroke.
Swim seats complying with this standard improve the in-water stability and minimise the entrapment risk in case of capsizing. Children in swim seats do however require very close parental supervision. Overload beyond specified body weight, breaking waves and violent external forces are remaining risks that can cause capsizing. Shallow water is likely increase the risk of capsizing and to hinder or block the escape from the seat in case of emergency.

EN ISO 12402– 7:2006, Personal flotation devices — Part 7: Materials and components — Safety requirements and test methods (ISO 12402-7:2006) EN ISO 12402-9:2006, Personal flotation devices — Part 9: Test methods (ISO 12402-9:2006) 3 Terms and definitions For the purposes of this document, the following terms and definitions apply.
3.1 buoyancy resultant upthrust of a swimming device when totally submerged in fresh water with its uppermost part just below the water surface 3.2 inherent buoyancy upthrust provided by material which is less dense than water or by sealed chambers filled with air or gas 3.3 buoyant swimming device garment or device which when worn or held correctly will provide the buoyancy required to become familiar with movement through the water, assist with learning to swim or to improve swimming strokes

3.12 component sub group of the entire device which contributes to either buoyancy, function or safety 3.13 swim seat buoyant device intended to introduce the user to the aquatic environment and to build water confidence as a pre-requisite to learning to swim.
Swim seats provide safety for the user but do not guarantee protection against drowning
NOTE Swim seats are learning aids and should not be mistaken with aquatic toys as defined in EN 71-1. 3.14 swim seat system integrated components (parts) of a swim seat which contribute to stable floating conditions and to safety during normal use or after an emergency capsizing

3.16 assessment panel group of three people from an accredited and notified test house, all of whom are experienced in assessing buoyant swimming devices 3.17 kick board buoyant device designed to be held in the hands or by the arms in order to support the body in a horizontal and stable position in the water to assist the user to improve swimming techniques 3.18 pull buoy buoyant device to be held between the legs to maintain the legs in a horizontal position in the water to assist the user to improve swimming techniques 4 Classification 4.1 General Buoyant swimming devices shall be classified according to Table 1: Table 1 — Classification of buoyant devices Class Description A Device in which the child is in contact with the water positioned inside the buoyant structure. This device is intended to allow the user to become familiar with the water environment and movement through it. The device will keep the passive user in a stable floating position so that the base of the chin is at or above the surface of the water. B Buoyant swimming device intended to be securely attached to the body and to introduce the active user to the range of swimming strokes. C Device intended to be held in the hands, by the body or between the legs and to assist with swimming strokes and/or improving specific elements associated with swimming techniques. 4.2 Categorisation The requirements given in Table 2 were chosen to ensure compliance between swim seat sizes and manikin in all relevant test procedures. Table 2 — Values for categorisation Age
years Mass (equivalent to age)a Minimum buoyancy
N Manikin ≤ 1 ≤ 11 kg 100 I > 1 to 2 > 11 to 15 kg 120 II > 2 to 3 > 15 to 18 kg 140 III a For categorisation, marking and use priority shall be given to the values representing the body mass, age groups have been
added for rough orientation (See 8.2, Figure 1).

The size of the leg holes, when tested in accordance with Annex I, shall not allow the probe to pass through. 5.4 Materials 5.4.1 Thread To sew load bearing components, only threads manufactured from synthetic materials whose properties correspond to polyester or polyamide fibres shall be used.
5.4.2 Resistance to puncturing Where buoyant swimming devices incorporate air filled buoyancy chambers, the chambers shall remain airtight when tested in accordance with the procedures given in Annex H. 5.4.3 Resistance of foam and other inherent buoyant material to water absorption
When tested in accordance with the procedures given in 5.5.5 of EN ISO 12402-9:2006, the material sample shall lose no more than 10 % of its original buoyancy. The materials shall be tested using a new and conditioned sample of the inherent buoyant material. 5.4.4 Resistance of foam and other inherent buoyant materials to compression
Buoyant swimming devices manufactured from foam or other inherently buoyant materials shall be capable of withstanding compression and other movements in normal use without sustaining permanent loss of buoyancy. When tested in accordance with 4.8 of EN ISO 12402-7:2006, a new and conditioned sample of the buoyant material not used in other tests shall not lose more than 10 % of its buoyancy.
5.4.5 Migration of certain elements
Swimming devices shall conform to the requirements given in EN 71-3. A new and unconditioned complete device shall be tested.
5.4.6 Resistance to chlorinated salt water
After the complete enhanced conditioning according to the procedures in 6.1, the entire deflated device shall be tested for change in colour and damage. The change in colour shall be tested according to EN 20105-A02

When tested in accordance with the procedures in Annex C, the change in colour of the markings on the grey scale shall be 3 or better when assessed according to EN 20105-A02. 5.4.7.3 Resistance of the markings to perspiration
When tested in accordance with EN ISO 105-E04 the change of colour of the markings on the grey scale shall be 3 or better when assessed according to EN 20105-A02. 5.4.7.4 Adhesion of markings When tested in accordance with the procedures in EN ISO 105-X12 (wet and dry, 100 cycles) the markings shall not be damaged and shall remain legible in all details when assessed by the assessment panel. 5.5 Strength 5.5.
