5. Title, number of pages and language(s) of the notified document:  DEAS 1150: 
2023, Plastic monobloc chair — Specification, First Edition; (52 page(s), in English)  
6. Description of content:  This Draft East African Stand ard specifies requirements and 
test methods for the evaluation and selection of plastic monobloc chairs for adults.  
This standard does not cover chairs intended for children and bathroom use.  
This East African Standard allows for two levels of performance based on the end use of 
the chair, domestic or commercial. The forces used are sufficient to apply to chairs 
intended for adult use and also to ensure that a chair meets the minimum requirements 
in its intended environment, but do not ensure th at failure will not eventually occur either 
as a result of habitual misuse or after three years of service.  
With the exception of the seat and back loading point determination and the seat impact 
test, test results are dependent on the loads being correctl y applied, therefore for the 
remaining tests, apparatus equivalent to that listed may be used. In the case of designs 
not catered for in the test procedures, the test should be carried out as closely as possible 
to that described and deviations from the te st procedure noted on the test report.  
The strength and durability of the chair are determined by the application of static, impact 
and fatigue tests. The forces used are sufficient to allow for normal functional use. 
Strength and durability are detailed i n Clause 4. The stability of the chair is determined G/TBT/N/BDI/365 • G/TBT/N/KEN/1445 • G/TBT/N/RWA/876 • G/TBT/N/TZA/979 •

  by both the application of impact forces and by applying loads that could normally be 
encountered. Stability is detailed in Clause 5 and by tilting the chair to simulate normal 
functional use. The tests provide a procedure that will allow comparative analysis of the 
stability of various chairs under relatively fixed conditions. Chair stability is related to 
personal sitting habits, chair style, use conditions, floor finish and condition as well as 
design of the chair legs, which are variables complicating the fixing of minimum 
requirements. The minimum acceptance level is based on the weight and style of chair 
for both forwards and rearwards overturning.

facilitating trade
