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 barr iers that are encountered when goods and services are exchanged 
within the Community will be removed.  
In order to achieve this objective, the Community established an East African Standards Committee mandated 
to develop and issue East African Standards.   
The Committee is composed of representatives of the National Standards Bodies in Partner States, together 
with the representatives from the private sectors and consumer organizations. 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 finalization of standards, in accordance with the procedures 
of the Community.  
East African Standards are subject to review, to keep pace with tech nological advances. Users of the East 
African Standards are therefore expected to ensure that they always have the latest versions of the standards 
they are implementing .  
DEAS 1153:2023  was prepared by Technical Committee EASC/TC 035, Steel and steel products . DEAS 1153:2023

mitred. The corners of fixed and opening frames shall be welded to form a solid fused welded joint 
conforming to the requirements given in 6.6.1.1. All frames shall be square and flat.  The process of 
welding adopted shall be flash butt welding or can be any other process as agreed to between the 
manufacturer  and the purchaser which shall fulfil the requirements given in 6.6.1.1 to 6.6.1.4.  
6.6.1.1 Visual inspection test  
When two opposite corners of the  frames are cut, paint removed and inspected, the joint shall 
conform to the following:  
a) welds shall be made all along the place of meeting the members;  
b) welds shall be been properly ground; and  
c) complete cross section of the corner shall be checked up to see that the joint is completely solid 
and there are no visible cavities.  
6.6.1.2 Micro examinations

be cut with the help of a saw. The cut surfac es of the remaining portions shall be polished, etched and 
examined. The polished and etched faces of the weld and the base metal shall be free from cracks 
and reasonably free from under cutting, overlaps, gross porosity and entrapped slag.  
6.6.1.3 Macro -examinations  
Two opposite corners of the frames shall be cut and prepared for macro examination and examined 
with hand lens of magnification of not less than five. Complete cross section of the corner shall show a 
joint completely solid and with no visible  cavities, under -cutting and overlaps.

used or where the casement of the window is located in heavily exposed situation, holes for glazing clips will have to be 
drilled during fabrication.  
NOTE 2 Where the glass pane size does not exc eed 600 mm x 300 mm, glazing clips not considered necessary (for 
inside glazed windows for special use only two spring glazing clips per pane should be provided). In case of doors, 
windows and ventilators without horizontal glazing bars, through glazing cl ips may be spaced according to the slots in the 
vertical members, provided the spacing does not exceed 300 mm.  DEAS 1153:2023  
8.3.4 Windows may also be prepared for brad glazing made from either, 9.5 mm x 9.5 mm , aluminum channel 
of 1 mm thickness or 9.5 mm x 9.5 mm pres sed steel channel of minimum 0.45 mm thick galvanized sheet.  
8.3.5 Self tapping screws shall be used for fixing bead or alternatively bead fixing can be done with concealed 
screws. Back putty or ‘V’ shaped rubber channel wall shall be provided for glazing.  No spring glazing clip shall 
be required for bead glazing.  
 
9 Finish  and Workmanship  
9.1 Pre-treatment  
Methods to pre -treat the surface of the door frames, prior to painting or coating, shall be selected as per ISO 
8504 -1 to provide a cleaned surface free  from rust, dirt, grease, oil, loose scale, weld spatter and any other 
foreign matter. Any other mechanical means such as sand and shot blasting or chemical means that can 
provide the same degree of cleanliness may be applied.  
9.2 Hot dipped galvanizing   
After pretreatment of the surface the units shall be dipped in a bath of molten zinc in accordance with the 
requirements laid down in ISO 1461 . The thickness of coating shall be uniform and not less than 0.5 kg/m.  
9.3 Phosphating and painting   
9.3.1 All sur faces of the door, windows and ventilator including interior non -visible surfaces, shall receive a 
factory prime coat complying with the provisions of ISO 12944 -5.

view as part of paint finishing as per ISO 12944 -5. 
9.3.3 If door, windows and ventilator are not factory finish painted, a compatible coat of finish paint shall be 
applied in the field. The finish paint shall be of a type recommended for use on prime -painted steel. Consult 
the door and frame manufacturer’s literature for description of primer used. The manufacturer of the finish 
paint should verify compatibility with the primer.  
NOTE : A red oxide primer so applied as to give a dry film thi ckness of at least 20 micrometer.  
9.3.4 After pretreatment of the surfaces, the units shall be dipped in phosphating solution in accordance with 
the requirements laid down. This shall be allowed by one coat of paint which shall be air -dried or stove -dried 
after applying.  
9.3.5 Paint shall be applied on the units by any of the following methods:  
a) brushing using ready mixed paints;  
b) spraying with suitable primers; or  
c) dipping the complete unit in bath of suitable primer paint, such as red oxide zinc chr ome primer and 
then air drying.  
9.4 Workmanship  
Surfaces of frames that can be seen after a unit has been built in shall meet the followings:  
a) be smooth level with the faces of the members;  
b) show no unsightly hammer or grinding marks; and  
c) irregula rities such as burrs or weld fins shall be removed from hidden surfaces but need not be 
ground smooth.

 Annex C 
(Normative ) 
Strength of welded joints  
C.1 Strength of welded corners  
C.1.1 Cut out a typical corner of the frame so that the legs are approximately 250 mm long. Grip one leg in a 
vice so that the distance between the jaws of the vice and the inner edge of the free leg is 75 ± 5 mm.  
C.1.2 Twist the f ree leg through 90° in a plane perpendicular to the axis of the clamped leg.  
C.1.3 Repeat this procedure in the opposite direction of twist and with the other leg gripped in the vice and 
then examines  the corner for compliance with the requirements of Ann ex C.1.4 (see also figure 3). When 
relevant, repeat the test on a corner of each opening portion of the frame unit.  
C.1.4 There shall be no sign of discontinuity in the weld or of fracture of the weld due to porosity or slag 
inclusion.
