iv Foreword  
 
This Kenya National Workshop Agreement Standard has been prepared by the National Workshop 
Agreement meeting under the supervision of the Standards Project Comm ittee and in accordance with the 
procedures of  the Kenya Bureau of standards.  
 
An apron  is an outer protective garment  that covers primarily the f ront of the body. It may be worn for 
hygienic reasons as well as in order to protect clothes from wear and tear. The apron is commonly part of the 
uniform  of several work categories, includi ng waste handlers, nurses , and domestic workers . Many 
homemakers  also wear them. It is also worn as a decorative garment by women. Aprons are also worn in 
many commercial establishments to protect workers clothes from damage, mainly b ib aprons, but also others 
such as blacksmith  or farrier  aprons.  
 
In addition to cloth, aprons can be made from a vari ety of materials. Rubber aprons are commonly used by 
persons working with dangerous chemicals, and lead aprons are commonly worn by persons such as X -ray 
technicians who work near radiation. Aprons, such as those used by carpenters, may have many pockets t o 
hold tools. Waterproof household aprons, made of oilcloth or PVC are suitable for cooking and washing 
dishes.

Part 3:  
 
Plastic apron — Specification  
 
 
 
1 Scope  
 
This Part 3 of this National Works hop Agreement specifies the materials, dimensions, making -up and 
labelling requirements , sampling and test methods for protective ap prons used for wet work by the h ealth 
care wastes management.  
 
2 Definitions  
 
For the purposes of this standard, the follow ing definitions shall apply;  
 
2.1 
health care waste commodiity  
these are devices used to safegurd a person against hazards or injury during  handling,  segregga tion 
,storing ,transportation and disposal of the wastes that are produced in the day to day prov ision of health 
care.  
 
2.2 
plastic aprons  
these are overgaments used for shielding against dirt, hazards,  injury likely to arise from handling  health 
care waste material  
 
3 Requirements  
 
3.1 Materials  
 
3.1.1  The apron shall be made of plastic material t hat is resistant to corrosive elements, not easy to tear 
and easy to wash ( see KS 1148 -2, Specification for fabrics for water  resistant clothing  —  Part 2: PVC-
coated  fabrics ). 
 
3.1.2   Eyelets and press stud fasteners shall be of non ferrous metal, nickel plated or of PVC.  
 
3.1.3  The PVC coated fabric shall have a total mass per unit area of not less than 140 g/m2.   
 
3.2 Dimension s 
 
3.2.1   Aprons shall be not less than 900 mm long and not less than 750 mm wide across the skirt.  
 
3.2.2   The bib top shall b e not less than 250 mm wide extending to the full width of the apron over a depth 
not less than 200 mm and not more than 300 mm.  
 
3.2.3   Where straps are supplied are supplied with apron they shall have the following minimum lengths 
measured from the edge of the apron:  
 
a)  waist straps 500 mm  
 KS 2409 -3: 201 8 
 
2 b)  shoulder straps 750 mm  
 
c)  neck loop (strap) 500 mm.  
 
3.3 Making -up 
 
3.3.1  There shall be no seams or joints in the main body of the apron.  
 
3.3.2  For the purpose of attaching straps or eyelets the corners of th e bib and waist shall be reinforced 
with triangular pieces of self materials stitched or welded except where weldable eyelets are used or where 
the fabric mass per unit area is greater than 270 g/m2. 
 
3.3.3  Sewing shall not be less than four and not more t han five stiches per 10 mm. The sewing threads 
shall be positioned clear of any stitching.  
 
3.3.4  Strap strength  
 
The strap shall have a strength of 500 N,  when measured as per the method described in Annex A.  
 
3.3.5 Straps (either permamnently fixed or wi th a quick release fastening) shall be at least 10 mm in finishng 
width and finished to prevent fraying.

4 Sampling  
 
Representative sample of the aprons shall be randomly sel ected from the lot and tested appropriately. A 
sample shall be considered as having met the requirements of this National Workshop Agreement if it 
satisf ies all the requirements of this standards.   
 
5 Packaging  and  labelling 
 
5.1 Packaging  
 
Each apron sh all be packed in a n easy peel transparent  polyethene material pack.  
 
5.1 Labe lling 
 
Aprons comlying with this Workshop Agreement  shall be labelled with the following information legibly and 
indeliby in English and/or Kiswahili language.  
 KS 2409 -3: 201 8 
 
4 a)  the name, tra de mark or other means of identification of the manufacturer ; 
 
b)  the number of this standard ; 
 
c) cleaning or washing instruction ; 
 
d)  date of manufacture ; 
 
e)  the length and width of the apron ; 
 
f)  the country of origine/ or t5he words “Made in Kenya ”.

Annex A  
(normative)  
 
Strap attachment strength  
A.1 Apparatus  
 
A constant rate of extension tensile testing machine . 
 
A.2 Preparation of test specimen  
 
From the apron edge, cut at least  four specimens each wit h strap , leaving a clearance  on either side of 2.5 
cm from the strap edges and 10 cm from  apron edges as shown in Figure A.1.  
 
A.3 Atmosphere for conditioning and testing  
 
Prepare and test specimens in the standard temperature for conditioning and testin g as specified in ISO 139 , 
Textiles — Standard atmospheres for conditioning and testing.  
 
A.4 Procedure  
 
Set the gauge length of the tensile testing machine at 100 mm ± 1  mm. Select a set of clamps appropriate to 
the test. The clamps shall be parallel to e nsure that subsequent application of force to the specimen does 
not cause any angular deflection of the clamp.  
 
Mount the specimen centrally with the strap gripped by the upper jaw and apron by the lower jaw of a 
strength tester using a constant rate of tr averse speed of 100mm per minute; determine the strap attachment 
strength in accordance with ISO 13934 -1, Textiles -- Tensile properties of fabrics -- Part 1: Determination of 
maximum force and elongation at maximum force using the strip method . Repeat the  procedure for the other 
specimen. Determine the mean of the readings.
