Introduction
The structure of safety standards in the field of machinery is as follows:

a) type-A standards (basic standards) giving basic concepts, principles for design, and general aspects

that can be applied to machinery;

b) type-B standards (generic safety standards) dealing with one or more safety aspects or one or more

types of safeguards that can be used across a wide range of machinery:

— type-B1 standards on particular safety aspects (e.g. safety distances, surface temperature,

noise);

— type-B2 standards on safeguards (e.g. two-hand controls, interlocking devices, pressure-

sensitive devices, guards);

c) type-C standards (machinery safety standards) dealing with detailed safety requirements for a

particular machine or group of machines.
This document is a type C standard as stated in EN ISO 12100.

The machinery concerned and the extent to which hazards, hazardous situations and hazardous events

are covered are indicated in the scope of this document.

When provisions of this type C standard are different from those which are stated in type A or B

standards, the provisions of this type C standard take precedence over the provisions of the other

standards, for machines that have been designed and built according to the provisions of this type C

standard.

hazardous situations and events, as listed in Annex A, relevant to this equipment when used as intended

and under the conditions of misuse reasonably foreseeable by the manufacturer during normal

operation and service.

When requirements of this part of the EN 13451 series are different from those which are stated in

EN 13451-1, the requirements of this part of the EN 13451 series take precedence over the

requirements of EN 13451-1 for machines that have been designed and built according to the

requirements of this part of the EN 13451 series.

The requirements of this part of the EN 13451 series take priority over those in EN 13451-1.

This document doesn’t apply to installations or equipment intended to move people into or out of a pool

tank.

This part of the EN 13451 series is not applicable to equipment which is manufactured before the date

of its publication as EN.

5 List of significant hazards

Table A.1 shows all the significant hazards, hazardous situations and events identified by risk

assessment as significant for this type of equipment and which require action to eliminate or reduce the

risk. Table A.1 also indicates where they are dealt with in this European Standard.

For a particular floor or bulkhead, a risk assessment should be carried out by the manufacturer to

identify any additional significant hazards so that suitable protective measures can be taken. Additional

hazards are outside the scope of this standard. EN ISO 12100 describes procedures for the identification

and evaluation of hazards.
6 Safety requirements and/or protective measures
6.1 General

Machinery shall comply with the safety requirements and/or protective measures of this clause. In

addition, the machine shall be designed according to the principles of EN ISO 12100 for relevant but not

significant hazards, which are not dealt with by this document.
---------------------- Page: 8 ----------------------
oSIST prEN 13451-11:2016
prEN 13451-11:2016 (E)

Unless specified otherwise, machinery shall comply with the requirements of EN ISO 13850 and

EN ISO 13857.

Hatches for service or cleaning in the moveable pool floor or the moveable bulkhead shall be minimum

of 600 mm for a dry situation, or 800 mm for a wet situation.

The pool design shall ensure good water treatment throughout the pool regarding the moveable floor

and or the moveable bulkhead. The design of water circulation should take into account the need of

equal flow in different pool areas when only a part of the complete pool is to be fitted with a moveable

floor or bulkhead.

Specific hazards and risks related to accessible elements (cables, gears, pulley, lamps, ladders and

products placed into the pool) dedicated to the floor/bulkheads movements/positions shall be assessed

when existing and should be taken into account in the risk assessment.

NOTE It may be necessary to tighten the construction tolerances of the structure and finishes within the

basin in order to meet the tolerances set out within this European Standard.
6.2 Moveable pool floors
6.2.1 General

The gradient of a moveable floor positioned at a water depth ≤ 1 350 mm shall be ≤ 6,6 %.

NOTE It is necessary to pay special attention to the construction tolerances of the structure and/or finishes

within the basin in order to meet the specification of EN 13451-1 within this European Standard.

In presence of a moveable pool floor, the pool water treatment system should be specifically designed

considering possible changes in designation (e.g. a swimmers pool used as non-swimmers pool).

To check the correct water distribution of the complete installation a dye test shall be carried out in

accordance with EN 15288-1 and EN 15288-2 with the moveable floor in 2 positions:

— the lowest operating position; and
— 1/3 of the operating water depth measured from water surface.

Compliance with the dye test is achieved when colouring of the water in the pool tank above the

moveable floor is attained in accordance with the requirements of EN 15288-1 and EN 15288-2 after

the dye is seen to clearly flow through the moveable floor.

NOTE It is likely that the cooperation of the pool builder will be required to achieve a suitable system.

Moveable floors shall allow inspection, cleaning and maintenance of the area underneath the moveable

floor.
6.2.2 Structural integrity

The structural integrity of moveable floors shall be verified using the following independently assessed

criteria:
— a vertical uniformly distributed load of 600 N/m ;

— a concentrated vertical load of 2 000 N/m over a square area of 1 m2 at any point;

— a concentrated vertical load of 2 000 N/m over a square area of 2 m × 2 m focussed in front of the

means of exit and similar areas.

6.2.3 Inadvertent movements

Abnormal movements of a moveable floor (e.g. caused by restoration of the power supply following an

interruption) shall be prevented.

The risks arising from small foreseeable movements during use and maintenance in water shall be

prevented.
6.2.4 Prevention of entrapment

Gaps on the surface of a moveable floor shall be ≤ 8 mm. The gap between the rigid part of a moveable

floor and the pool shall be ≤ 50 mm. When the gap is greater than 8 mm a closure device shall be used to

reduce the gap to ≤ 8 mm wide.
