 Foreword  
 
This Draft  Tanzania Standard is being developed by Industrial and Laboratory Chemicals Technical Committee 
under supervision of the Chemicals Divisional Standards Committee and it is in accordance with the procedures of 
the Bureau.  
 
This Draft Ta nzania Standard has been prepared with assistance drawn from:  
ASTM D2564 − 20 Standard Specification for Solvent Cements for Polyv inyl Chloride (PVC) Plastic Piping 
Systems,  published by ASTM International .  
 
In reporting results of a test or analysis made in accordance with this standard, if the final value, calculated or 
observed is to be rounded off, it shall be done in accordance with TZS 4 Rounding off numerical values .

3 Terms and definitions  
For the purposes of this standard, the following terms and definitions shall apply.  
3.1 
adhesive  
substance capable of holding materials together by surface attachment  
3.2 
adherend  
body that is, or is intended to be, held to another body by an  adhesive  
3.3 
shear  
mode of application of a force to a joint that acts in the plane of the bond -line. The force may be applied in 
longitudinal compression or tension or torsion  
3.4  
viscosity  
quantity expressing the magnitude of internal friction in a fluid  resisting uniform flow  
NOTE: The words “Polyvinyl chloride” and “Poly (Vinyl Chloride)” may be used interchangeably with the same 
abbreviation as “PVC ” 
 
4. Requirements  
4.1 General requirement  
The material shall be free from visible impurities and foreign matter .  
 
4.2 Specific requirements  
The material shall comply with the specific requirements in Table 1 when tested in accordance with the methods 
indicated therein.
