 Foreword  
Development of the East African Standards has been necessitated by the need for harmonizing requi rements 
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 exchanged 
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 representati ves 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, academia, 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 finalization of standards, in 
accordance with the Principles and procedures for development of East African Standards. XXXXXX.  
East African Standards are subject to review, to keep pace with technological advances. Users of the East 
African Standards are therefore expected to ensure that they always have the l atest versions of the standards 
they are implementing .  
The committee responsible  for this document is Technical Committee EASC /TC EASC/TC: 022 ,  
Attention is drawn to the possibility that some 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.

Figure 4 — Typical Particleboard or Medium Density Fibre board core flush door shutter  
4.4.2.2  The core shall be either particleboard or MDF board or a combination of blockboard and 
particleboard or blockboard and MDF board. In a combined construction, the width of blockboar d construction 
shall extend at least 150 mm from inner edge of the stile, on either side and the rest shall be particleboard or 
MDF board. Blockboard shall conform to the requirements specified in 4.4.1.2 and the particleboard and MDF 
board shall be as spe cified in 4.3.7 and 4.3.8 respectively. The frame for holding the core, including lipping 
where it occurs, shall not be less than 45 mm and not more than 100 mm in width.  
4.4.3  Stiles and rails  
Stiles and rails shall be made of one piece without any joint.  
4.4.4  Levelling  
Levelling, not necessarily by planning of surfaces, shall be carried out during each stage of construction, that 
is: 
a. fabrication of core; and  
b. bonding of cross -bands and face veneers.  
The thickness of core shall be checked for uniformity be fore bonding the plywood or cross bands and face 
veneers as the case may be.  
NOTE  In a blockboard construction, the impression of the core strips on the outside face maybe minimized to a large 
extent by following the provision of 4.4.4 but cannot be elimin ated altogether because of the nature of construction.  
4.4.5  Face panel  
4.4.5.1  The face panel shall be formed by gluing on both faces of the core either plywood or cross bands 
and face veneers by the hot press process. The thickness of the cross bands as such or in the plywood shall 
be between 1 mm and 3 mm. The thickness of the face veneer as such or in the plywood shall be between 0.5  
8 © EAC 2021  – All rights reserved  
 mm and 1.5 mm for commercial veneers and between 0.4 mm and 1.0 mm for decorative veneers, provided 
that the combined thi ckness of both is not less than 2.2 mm.  
4.4.5.2  The plywood conforming to these requirements shall be glued under pressure on both faces of 
the core. When the panel consists of cross bands and face veneers glued separately, the cross bands shall be 
laid wi th their grains at right angles to those of the core and glued to its both faces. Face veneer shall then be 
laid with their grains at right angles to those of the cross bands. Where it is desired to have wooden strips in 
the blockboard core horizontal rath er than vertical, this shall be permitted only if three -ply panel is pressed on 
both sides of the core and the total is a seven -ply construction.  
4.4.5.3  Application of a decorative face veneer on a finished face panel having veneer in the same 
direction a s the facing veneer shall be avoided. However, where, this is unavoidable due to special 
circumstances, the already existing veneer, whether commercial or decorative, shall be so sanded that the 
total thickness of both the existing and the applied face ven eers together shall not exceed the maximum 
thickness specified; the thickness of decorative veneer after finishing is, in no case, less than 0.4 mm.  
4.4.6  Lipping  
4.4.6.1  General  
Lipping shall be provided, if so desired by the purchaser. Lipping, where pro vided, may be concealed or 
exposed as  specified by the purchaser. Joints shall not be permitted in the lipping. Some typical ways of 
lipping are shown in Figure 5 for guidance.

Wooden flush doo r shutters, when tested, there shall not be any residual deflection of more than one tenth of 
the maximum deflection. The deflection at the maximum load shall not be more than one thirtieth of the length 
and one fifteenth of the width, whichever is less.  
5.2.6 Edge loading test  
Wooden flush door shutters, when tested, the deflection of the edge at the maximum load shall not be more 
than 5 mm. On removal of the loads, the residual deflection shall not be more than 0.5 mm. In case the door 
shutter is failing the above test, the test procedure may be repeated on the other edge in the reverse direction. 
Also there shall be no lateral buckling by more than 2 mm during loaded condition and no residual lateral 
buckling after removal of the load.  
5.2.7  Shock resista nce test  
5.2.7.1  Wooden flush door shutters, when tested, there shall be no visible damage in any part of the door 
after twenty five blows on each end.  
5.2.7.2  Wooden flush door shutters, when tested, the normally hung shutter, with hangings, fixings and 
fastenings should withstand without any significant permanent deformation and without deterioration the five 
impacts on both sides of the shutter.  
5.2.8  Buckling test  
Wooden flush door shutters, when tested, shall not show any deterioration and any residual  deformation more 
than 5 mm after 15 min of unloading and the initial deflection also shall not be more than 50 mm.  
5.2.9  Slamming test  
5.2.9.1  Anyone of the following tests given in 5.2.9.2 and 5.2.9.3 shall be used.  
5.2.9.2  Wooden flush door shutters, wh en tested, shall not have any visible damage in any part of the 
door at the end of 50 successive impacts.

 5.2.9.3  Wooden flush door shutters, when tested, shall not have any visible damage in any part of the 
door at the end of 100 successive impacts.  
5.2.1 0 Misuse test  
Wooden flush door shutters, when tested , there shall not be any permanent deformation of the fixing or any 
other part of the door set hindering its normal working after the test.  
5.2.11  Varying humidity test  
Wooden flush door shutters, when tested, there shall not be any visible warping, twisting or delamination and 
where precision is required, the maximum departure from the general planeness shall not be more than 1.0 
mm. The recovery of the original size after subjecting the door to high an d low humidity shall be at least 90 % 
of the change in dimensions.  
5.2.12  End immersion test  
Wooden flush door shutters, when tested, shall have no delamination at the end of the test. This test shall be 
carried out on door shutters only after they pass in  glue adhesion test.  
5.2.13  Knife test  
5.2.13.1  Wooden flush door shutters, when tested, the results of adhesion shall be as those given in 
5.2.13.2 to 5.2.13.4.  
5.2.13.2  The adhesion is excellent when it is difficult to find the glue line and impossible t o keep the tool 
within it for more than 6 mm without cutting into adjacent wood. On pressing upwards, the veneer/facing sheet 
usually breaks off over a width only slightly greater than that of the tool.  
5.2.13.3  The adhesion is poor when the knife meets li ttle opposition into the glue line and the prise results 
in the easy removal of almost all the veneers/facings sheets from one side of the tests specimen. The 
separated veneers/facing sheets are usually almost free from adjacent fibre.  
5.2.13.4  Wooden flus h door shutters designated as poor shall be declared as unsatisfactory.  
5.2.14  Glue adhesion test  
Wooden flush door shutters, when tested, shall be considered to have passed the test if no delamination has 
occurred in the glue lines in the plywood or if no  single delamination of more than 50 mm in length and more 
than 3 mm in depth has occurred in the assembly glue lines between the plywood faces and stile and rail. 
Delamination at a knot, knot hole, a pitch pocket and wormhole or other permissible wood def ects shall not be 
considered in assessing the sample. A Wooden flush door shutter shall be deemed to have passed the test if 
both the specimen tested passed the test.  
5.2.15  Screw withdrawal resistance test  
Wooden flush door shutters, when tested, the requ ired load to withdraw the screw completely shall not be less 
than 1 000 N. On withdrawal, there shall be no visible damage to the surface either by delamination or extra 
chipping off at the points of withdrawal.  
6 Sampling and criteria for conformity  
6.1 Lot in any consignment  
All wooden flush door shutters of the same type and manufactured under similar conditions of production shall 
be grouped together to constitute a lot.
