Uganda National Bureau of Standards (UNBS) is a parastatal under the Ministry of Trade, Industry and 
Cooperatives established under Cap 327, of the Laws of Uganda, as amended.  UNBS is mandate d to co -
ordinate the elaboration of standards and is  
(a) a member of International Organisatio n for Standardisation (ISO),  
(b) a contact point for the WHO/FAO Codex Alimentarius Commission on Food Standards, and  
(c) the National Enquiry Point on TBT Agreement of the  World Trade Organisation (WTO).  
The work of preparing Uganda Standards is carried out through Technical Committees. A Technical 
Committee is established to deliberate on standards in a given field or area and consists of representatives of 
consumers, trad ers, academicians, manufacturers, government and other stakeholders.  
Draft Uganda Standards adopted by the Technical Committee are widely circulated to stakeholders and the 
general public for comments. The committee reviews the comments before recommending  the draft standards 
for approval and declaration as Uganda Standards by the National Standards Council.  
This Uganda Standard, US EAS 1020 : 2019 , Shovels and spades — Specification , is identical with and has 
been reproduced from an East African  Standard, EAS 1020 : 2019 , Shovels and spades — Specification , and 
adopted  as a Uganda Standard.  
The committee responsible for this document is Technical Committee UNBS/TC 4 , Mechanical engineering 
and metallurgy . 
Wherever the words, “ East African  Standard " appear, th ey should be replaced by "Uganda Standard."

 Foreword  
Development of the East African Standards has been necessitated by the need for harmonizing requirements 
governing quality of products and services in the East African Community. It is envisaged that through 
harmonized standardization, trade barriers that are encountered when goods and services are exchang ed 
within the Community will be removed.  
The Community has established an East African Standards Committee  (EASC)  mandated to develop and 
issue East African Standards  (EAS) . The Committee is composed of representatives of the National 
Standards Bodies in Partner States, together with the representatives from the public and private sector 
organizations  in the community .  
East African Standards are developed through  Technical Committees that are representative of key 
stakeholders including government, academ ia, consumer groups, private sector and other interested parties. 
Draft East African Standards are circulated to stakeholders through the National Standards Bodies in the 
Partner States. The comments received are discussed and incorporated before finalizat ion of standards, in 
accordance with the Principles and procedures for development of East African Standards.  
East African Standards are subject to review, to keep pace with technological advances. Users of the East 
African Standards are therefore expecte d to ensure that they always have the latest versions of the standards 
they are implementing .  
The committee responsible for this document is Technical Committee EASC /TC 042, Production and general 
engineering .  
Attention is drawn to the possibility that s ome of the elements of this document may be subject of patent 
rights. EAC shall not be held responsible for identifying any or all such patent rights.

4.1.2  The handle shall be made of the material that facilitates compl ete bonding with the hilt and the socket 
and facilitate firm grip by the user. If it is made of wood it shall be hard wood with a specific gravity of 0.66 to 
0.8 seasoned to not more that 20 % moisture content on dry basis.  
4.2 Hardness  
The blade when test ed up to 45 % of its height measured from the cutting edge and  in accordance with ISO 
6508 -1 shall have a hardness of 39 HRC – 48 HRC  or its equivalent.

 4.3.2  The handle shall be tested for strength by clamping it and subjecting the same to a static load of 50 kg 
at a radius of 750 mm for an hour without brea king or showing a permanent deformation (see figure 1). 
 
 
Figure 1 – Handle and grip strength test  
4.4 Dimensions  
Dimension of the shovel and spades should be as specified in annex A.  
5 Methods of test  
5.1 Bend test for spades  
Using a vice (see figure 2 ) fitted with a 50 mm cylindrical insert of length at least equa l to the width of the 
blade under test, clamp the blade to a depth of 50 mm from the tip of its working edge. So apply a load in the 
appropriate direction to the hilt that the blade bends over the cylindrical insert and the hilt moves through an 
angle of 7 5°.

Figure 2  — Bend test for spades  
5.2 Strength test for sockets, shafts and hilts  
5.2.1 Support the tool as shown in figure 17. Gradually apply a load to the hilt such as to impose a bending 
moment at the shoulder of the blade, equal to the relevant o f: 
50 kg  in the case of spades with blades of nominal thickness 2 mm; or  
36 kg in the case of spades with blades of nominal thickness 1.6 mm, and all shovels.  
5.2.2 Maintain the bending moment for a period of 2 min and then release it;  
5.2.3 Immediately me asure the vertical deflection of the grip from its initial position, and take this to be the 
permanent set.

not in direct contact with the soil shall have an anti - corrosion paint coating.  
6 Sampling  
6.1 Lot 
6.1.1 If the entire stock  is of homogenous quality then in effect, the stock  shall comprise a single lot. A 
sample of specified size may then be selected directly upon opening the stock . 
6.1.2 If the lot is composed of boxes (for instance, each from a different manufacturer) then sampling shall 
be conducted in two stages. First select a sample number of boxes and  then select a sample of hoe s from 
within each selected box.  
6.1.3 Once the samples have been selected, they shall be legibly marked (for example 1, 2, 3, etc.) and the 
box from which they were taken also marked so that each can  be sourced back to the box from which it was 
taken.  
6.2 Sample size  
6.2.1 A zero-based acceptance sample shall be selected based on an  Acceptable Quality Level  of 2.5 %. 
The sample sizes to be selected are as given  in Table 3 .
