European foreword
This document (prEN 14404-4:2019) 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 document is currently submitted to the CEN Enquiry.
This document will supersede EN 14404:2004+A1:2010.
This document has been prepared under a mandate given to CEN by the European Commission and the
European Free Trade Association, and supports essential requirements of EU Directive(s).
For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this
document.
This standard “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 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)

Introduction
Kneeling is a frequently occurring working position, but one which is problematic from an occupational
health viewpoint. Without knee protectors, workers may 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 may 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, as should footwear.
For working in kneeling position exist 4 types of knee protectors:
— wearable knee protectors (type 1),
— knee pads in combination with garments (type 2),
— knee mats (type 3) and
— kneeling systems (type 4)
This document describes test methods, specifies requirements for knee protectors and defines
performance levels. Requirements for the marking of knee protectors and the information to be
supplied by the manufacturer are given. Where protection against additional hazards is claimed,
performance requirements from other applicable standards may also be applied.
This document does not apply to knee protectors that are medical devices or are intended for sports
and motorcycles.

1 Scope
This document specifies the requirements for interoperable knee pads to use in garments (type 2) and
for garments to use with interoperable knee pads for use by work in kneeling position.
In addition to the combination test according to part 3 of this series, for which the garments and the
associated padding are to be provided for testing, it is generally possible to combine padding
standardized in its size with garments made to this size.
