Quality Standards

 

CERTIFICATION OF ORIGIN
MTS declares that all its exhaust systems are produced in the plant MTS SPA in Mansué (TV) Italy.

CONFORMITY TO THE ORIGINAL PART
Pursuant to the side figures 19 and 20 of the complementary guidelines for vertical limitation in agreement concerning the sale and repair of motor vehicles and the distribution of spare parts dated May 28, 2010
Our original spare parts show the same quality as the parts used for building the vehicle and are produced meeting the specifications and standards of the car manufacturer; the qualitative equivalent parts offered, are qualitative equivalent in terms of the side figure 20 of the guideline.
This certification substitutes the KFZ-GVO 1400/2002 certification, which expired on 31th May 2010.

MATERIALS
To produce the exhaust systems we use only raw materials that are purchased from the supplier in conformity to the UNI EN ISO 9001 rules

MATERIAL APPLICATION THICKNESS/DIAMETER UNI EN / ISO
PIPE Internal and exterior 15/10 10305-3/5 e 10296-2
SHEET Body 06/10+06/10 10327 e 10088
SHEET End cap 20/10 10327 e 10088
SHEET Interior cap 15/10 10327 e 10088
FIBER GLASS Interior   2078
FIBER Welding   440-G
BAR Hangers 08 - 10 - 12 10277-2
FLANGES Connections   10210-1

 

PHONO ABSORBENT MATERIAL
According to the EC Regulation Nr. 1272/2008 and to EC Directive Nr. 2006/121, we declare that in the MTS exhausts, when necessary, as silencing material fiber glass is used, and never rock wool.
Our silencers do not contain neither asbestos nor CMRs substances i.e. carcinogens, mutagens and reproductive toxins (like Phenol C6H5OH and the Formaldehyde CH2O) which are all present in the rock wool.

SPECIAL PROCESSES
The welding is a special process because the quality checks would destroy the tested part. So MTS has qualified the personnel and has confirmed the parameters of indirect verification, in order to keep efficient and reliable this production process:

TYPE     UNI EN / ISO
PERSONNEL     287-1
PARAMETERS     15614
The welding process is carried out as follows:
TYPE ROBOT AUTOMATIC MACHINES BY HAND
FLANGES 100%    
SILENCERS 60% 30% 10%
