QUALITY GUARANTEE

The international standard BDS (Bulgarian National Standard) EN ISO 9001: 2015 was established to guarantee the ability of the organization to constantly provide quality products and services, which match the designated requirements.

The introduction of a quality management system in Trierra LTD in 2003, according to the international standard BDS EN ISO 9001:2015, is a strategic decision of the upper management. This certification has been covered for 22 years with yearly control and periodic recertification audits.

Laboratory Testing Complex

Trierra has invested in the construction of a laboratory testing complex – LTC Trierra, in which highly qualified technical specialist test separate bearing lots from the various manufacturers.

This procedure is followed not only for both new brands and for bearings which the firm considers offering to their clients in and out of the country, but also for control of the bearings which are already popular on the market, and for evaluation of the bearing providers.

Our LTC is equipped with the most up-to-date precise measurement machinery and stands, along with the required precise benchmarks, and the necessary engineering personnel.

The main role of the LTC in guaranteeing the quality of the bearings is the control of the accuracy parameters of the inbound and outbound production. To achieve this goal, the sample pool is as large as possible to ensure maximum legitimacy.

Measurement of Vibrations - BVT-6

The bearings we work with must correspond to the main norms - ISO and EN.

The evaluation is conducted in our Laboratory Testing Complex with the following measurements:

Gauge dimensions of the various bearing types and other complimentary products:

ISO 15, ISO 355, ISO 104, ISO 113, ISO 2982, ISO 582, ISO 3030, ISO 3290, ABMA 19, ABMA 20

Technical requirements – margins of dimensions and deviations from the geometric norm, chamfer, clearances:

ISO 492, ISO 199, ISO 578, ISO 355, ISO 582, ABMA 20

and for the railway bearings
EN1208

Strength parameters, load capacity, resource, maximum rotating speed:

ISO281, ISO 15, ISO 1531

Law on Control of Foreign Trade Activity in Arms and Dual-Use Goods and Technologies.

Methodology for control in the LTC in accordance with the bearing parameters – geometrical dimensions, clearances, hardness, deviation, and vibration level:

ISO 1132, ISO15242
