Quality you can trust
Quality, reliability and safety are at the heart of everything we do. To ensure our products consistently meet the demanding standards of the commercial vehicle industry, every component undergoes a comprehensive quality assurance process before it reaches the market.
From initial development to series production and long-term performance testing, every step is carefully monitored and validated. This commitment enables us to offer:
- 24-month guarantee on products of the DT Spare Parts brand
- Consistently high product quality and reliability
- Continuous product improvement based on testing and field feedback
Our in-house testing capabilities and strict inspection procedures ensure that every product meets the expectations of professional users worldwide.
Initial sample inspection
Thorough validation before production begins
Before a product enters series production, the supplier manufactures an initial sample based on the defined product specifications. This sample undergoes a detailed inspection by Diesel Technic specialists in Germany.
During the approval process, every relevant requirement is carefully evaluated, including:
- Compliance with technical specifications
- Dimensional accuracy and functionality
- Material and performance requirements
- Safety and quality standards
Only products that successfully pass all inspection criteria receive approval for series production. This ensures that quality expectations are met from the very beginning of the manufacturing process.
Series inspection & continuous performance testing
Consistent quality throughout the product lifecycle
Maintaining high quality does not stop after production approval. Suppliers manufacture products using the latest production and inspection technologies, while every production batch is monitored according to predefined inspection plans.
Key elements of our ongoing quality assurance include:
- Batch inspections based on established quality standards
- Sample sizes determined according to ISO 2859-AQL
- Visual inspections during goods receipt
- Continuous monitoring of production consistency
- Regular quality assessments throughout the supply chain
In addition, our in-house Test Center in Germany plays a vital role in ensuring long-term product performance.
Using self-developed test benches, we simulate a wide range of real-world operating conditions and conduct extensive durability tests. Our specialists evaluate every result and initiate further optimization measures whenever required.
To complement laboratory testing, we also carry out regular field tests with selected competence partners and test fleets. The insights gained from these practical applications are continuously integrated into the development process, helping us further enhance the quality, reliability, and longevity of our branded products.
