Quality Assurance
The quality assurance system enforced at Deki, certified in accordance with ISO 9002 since November 1994, has been upgraded to ISO 9001:2000 in December 2003. It is based on quality procedures as laid out in the quality manual. The procedure has been developed taking into consideration international standards, customer requirements and internal performance standards. The system is designed to ensure satisfaction of customers in respect of quality, functional performance, delivery performance, price / performance ratio and overall service satisfaction. Deki team members have been extensively trained to follow principles of “first time right” and in case of all corrective actions, the PDCA cycle.

Quality assurance is an all pervasive activity at Deki, transcending all vital functions starting from raw material vendor selection, sourcing, incoming inspection through process inspection to final inspection and storage/ despatch. Modern quality tools such as the 7 QC tools, Statistical Process Controls (SPC), Failure Mode and Effects Analysis (FMEA), Design of Experiments (DOE) and Cause and Effect Diagram with Addition of Cards (CEDAC) are used regularly to ensure continual improvement in quality and reliability.

AQL (Acceptable quality level): All outgoing inspection is carried out as per Inspection Standard ISO 2859 / IS 2500 or IEC 410. Sampling plan followed is single sampling for normal inspection. AQL for all electrical properties is 0.1; this ensures that not even a single failure is acceptable.

Reliability
All capacitors are subject to qualification approval test as per relevant IEC standards in order to ensure reliability:
Plain Polyester film / foil capacitors: IEC 384-11
Plain Polypropylene film / foil capacitors: IEC 384-13 Metallised Polyester film capacitors: IEC 384-2
AC & Pulse MPP film capacitors: IEC 384-17 Interference Suppression Capacitors: IEC 384-14

The environmental and endurance testing is carried out periodically at the in-house test laboratory.
