European foreword
This document (EN 14404-4:2024) has been prepared by Technical Committee CEN/TC 162 “Protective
clothing including hand and arm protection and life jackets”, the secretariat of which is held by DIN.
This European Standard shall be given the status of a national standard, either by publication of an
identical text or by endorsement, at the latest by November 2024 and conflicting national standards shall
be withdrawn at the latest by November 2024.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN shall not be held responsible for identifying any or all such patent rights.
This document, together with EN 14404-1 to EN 14404-3 and EN 14404-5 to EN 14404-6, will supersede
EN 14404:2004+A1:2010.
This document has been prepared under a standardization request addressed to CEN by the European
Commission. The Standing Committee of the EFTA States subsequently approves these requests for its
Member States.
For the relationship with EU Legislation, see informative Annex ZA, which is an integral part of this
document.
EN 14404 “Personal protective equipment — Knee protectors for work in the kneeling position” is split into
6 parts:
— Part 1: Test methods;
— Part 2: Requirements for wearable knee protectors (type 1);
— Part 3: Requirements for the individual combination of knee pads and garments (type 2);
— Part 4: Requirements for the combination of interoperable knee pads and garments (type 2);
— Part 5: Requirements for knee mats (type 3);
— Part 6: Requirements for kneeling systems (type 4).
With the splitting of the standard, the following changes were made:
— definition of the protection zone;
— new combination of interoperable knee pads with interoperable garments (EN 14404-4);
— a bend test for interoperable knee pad was introduced;
— normative references were updated, further normative references are included;
— the cleaning of garments was taken into account;
— an uneven test surface and test was introduced;
— no more "UNISIZE" size; adjustment of size designation;
— additional markings were added.
Any feedback and questions on this document should be directed to the users’ national standards body.

Introduction
Kneeling is a frequently occurring working position, but one which is problematic from an occupational
health viewpoint. Without knee protectors, workers can suffer immediate injuries from hard surfaces and
small stones and similar objects lying on the surfaces. However, no knee protector can ensure that
workers will not suffer medical complications if they are required to kneel for long periods.
It is important that knee protectors do not compromise venous drainage in the leg while kneeling or
standing up. Therefore, it is important that it is easy for workers to change position and to stand up to re-
establish a normal blood circulation at frequent intervals while wearing knee protectors.
Work in a kneeling position involves the risk of chronic diseases such as prepatellar bursitis and cartilage
injuries caused by continuous pressure on the knees. Knee protection is therefore recommended for all
work in the kneeling position. The protection should distribute forces evenly and prevent small hard
objects on the ground causing injuries. Many workers have pre-existing damage to their knees,
particularly to their cartilages from sports injuries and from previous work. These injuries will be made
worse by further kneeling. Wearing knee protectors cannot correct existing damage but should slow
down further damaging effects.
Work in a kneeling position can expose the skin of the shins, knees and thighs to toxic and corrosive
materials normally kept off the body while walking and standing by waterproof or water-resistant
footwear. Knee protectors and trousers for use with such wet materials and particularly wet cement,
should take this into account and provide adequate protection.
For working in a kneeling position, four types of knee protectors exist:
— wearable knee protectors (type 1),
— knee pads in combination with garments (type 2),
— knee mats (type 3), and
— kneeling systems (type 4).
Interoperable knee pads as removable protectors can be sold on their own. In these cases, the attention
should be given to the Guidelines of the PPE Regulation application (April 2018): "In case removable
protectors are placed on the market, they are required to be certified as PPE on their own, as these must
fulfil all the applicable requirements of the PPE Regulation (EU declaration of conformity, CE Marking, etc.)".
This document has been drafted to cover this situation as well.
1 Scope
This document specifies requirements for interoperable knee pads to use in garments and for garments
to use with interoperable knee pads and defines performance levels for use when working in a kneeling
position in order to reduce injuries to the knees caused by continuous pressure and penetration.
Requirements for the marking of the interoperable knee pad and the information to be supplied by the
manufacturer are given. Where protection against additional hazards is claimed, performance
requirements from other standards are applicable.
This document does not apply to knee protectors that are medical devices or are intended for sports and
motorcycles.
In this document requirements are given for a combination of a garment with a fixed sized knee pad
pocket and fixed sized knee pad (interoperable pad).
A specific combination of an individual pad and accordingly designed garment is described in EN 14404-3
and is excluded from this part.
