4 Requirements
4.1 General
Protectors shall be so designed and manufactured that in the foreseeable conditions of use for which they are intended, the user can perform the sporting activity normally while enjoying protection at the specified limit.
It shall be possible to clean the protectors in accordance with the manufacturer's instructions without the loss of the ability to fulfil the requirements of this document.
4.2 Innocuousness
Protectors shall be designed and manufactured to provide protection when used in accordance with the information supplied by the manufacturer, without any harm to the user or others when so used.
Materials, incorporated substances, seams and edges and particularly those parts of the protectors in close contact with the user shall not impair the user's health and hygiene.
The colour of protectors or parts of them shall be resistant to perspiration.
For textile materials, when tested in accordance with 5.3.1, this requirement is considered as fulfilled if, using an alkaline and acid solution according to ISO 105-E04,
——a fastness grade 3 to 4 according to ISO 105-A02 by the change in colour, and
——a fastness grade 3 to 4 according to ISO 105-A03 by staining will be reached.
For other materials, these requirements are considered as fulfilled if no staining of the used strips of filter paper is observed when they are tested in accordance with 5.3.2.
4.3 Restraint
The design of the protectors shall enable secure fixation to the body of the user, so that they will remain in place during the normal use for which they are intended. If secure fixation is not provided by restraint systems which are integrated elements or permanently attached to the protector, instructions shall be provided by the manufacturer describing a method of secure fixation.
If rigid, sharp edges and abrasive elements are part of the restraint system, they shall be completely covered by a soft padding.
The displacement of the protector from its original position shall be after each individual test less than 15 % of the linear dimension of the zone of protection (see 4.5 and Clause 7) measured in the line with the force supplied as specified in 5.4.
When tested according to 5.4, no parts of the restraint system shall break, split, be released or fail in any other way.
4.4 Sizing
Protectors shall be supplied in a number of different sizes to meet the requirements according to different body dimensions of wearers. The size shall be marked on the protector.
The specific sizing is defined in the relevant parts of ISO 21924.
4.5 Zone of protection
The dimensions of the zone of protection shall be as defined in the relevant parts of ISO 21924.
The manufacturer shall mark the zone of protection on the protector or in the information supplied by the manufacturer.
4.6 Impact performance
When tested according to 5.6, no part of the protector shall break, split or be deformed irreversibly.
Specific requirements are defined in relevant parts of ISO 21924.
