Purpose  
               ARTICLE 1  – (1) The purpose of this Communiqué is to identify issues related to the 
implementation of revision of TS 1441 -1 “Springs - Quality Requirements - Cylindrical Helical 
Compression Springs - Part 1: Made From Round Wire and Rods, Hot Formed” and TS  1441 -
2 “Cylindrical Coil Compression Springs Made From Round R ods - Part 2 : Q uality  
Requirements  For Mass Production ” standard s. 
              Scope  
           ARTICLE 2  –  (1) This standard ; covers the characteristics of hot-formed  cylindric al-
helical compression springs from circular  bar in description, classification and specifications, 
sampling, inspection and testing , and based on market supply.  The permissible deviations 
specified in this standard apply to helical compression springs that meet the following 
requirements : 
- Party size up to 5000 pieces  
- Rod or wire diameter,        d 8 mm to 60 mm  
- External coil diameter,      De ≤  460 mm  
- Unloaded spring length,    L0 ≤ 800 mm  
- Number of active turns ,    n ≥ 3  
- Turns in  rate, w 3 to 12  
 (2) In cases where  the party  size is 5000 pieces or more, TS 1441 -2 is applied.  This standard 
covers the description and testing of  cylindrical helical compression springs made of round 
bar. Springs covered by this standard are mainly used in vehicle suspensions. Vehicle 
suspension springs are generally manufactured in large scale and in automatic production lines.  
Therefore, manufacturing tolerances are narrower than TS 1441 -1. The permissible deviations 
specified in this standard, cylindrical helical compression, which meet the following 
requirements:  
- Mass production At least 5000 pieces  
- Rod length, l, up to 4300 mm  
- Rod diameter, d 9 mm to 18 mm  
- Unloaded spring length L0 (free length) up to 600 mm  
- External coil diameter , up to 180 mm  
- Number of active turns n  from 5 to 12  
- Turn  index, w 6 to 12  
- Total spring deflection  sc 180 mm and more  
- In cases where the group  size is 5000 pieces or more, TS 1441 -2 is applied.

TS 1441 -2 “Cylindrical  Coil Compression Springs Made From Round Rods - Part 2 : Quality 
Requirements For Mass Production”  were  adopted , decided to be published in the meeting of 
Technical Board of Turkish Standards Institution (TSE) dated 2/4/2015 and has been put into 
effect as mandatory in manufacturing and sales stages.  
           Compliance Obligation  
           ARTICLE 5 – (1) Those who produce and sell products on the market within the scope
