Quality Assurance System In Rishabh Instruments Pvt. Ltd.

The Quality Management System of Rishabh Instruments Pvt. Ltd. is in accordance to ISO 9001:2000, since April 1985.

QAS as a department is subdivided into four parts viz. Inward, In process, Final and Testing & Calibration.

Inward:

All incoming material into the factory is inspected at this section. Statistical quality control technique used is VQR (Vendor Quality Rating) and the sampling procedure used is as per IS 2500. Two Engineers and two operators are stationed in this section to cater to Electronic and mechanical component requirement.

In process:

The basic concept of this section is to built in “quality” in the processes itself. Critical stations are identified and setting patrol and final inspections are done at these stations. For special processes operator qualification and operator training is done. In process Quality plans are available to guide through the process of In process inspections

Final:

Final products are inspected at this section. The inspection is in two parts viz. electrical and packing. Quality plans are exclusively made per product to guide through the process of final inspection. The sampling procedure made is as per IS 1248. The statistical quality control technique used is D Merit Index

Testing and Calibration:

Rishabh Testing and Calibration laboratory equipped with modern amenities to carry out the followings:

1.	Type testing on different final products (for verification of design) as per IS/IEC/DIN/EN standards.

2.	Approval of components.

3.	In house calibration programme of all the instruments/ sources/ standards held by the factory.

4.	To co-ordinate the external calibration of standards.

Rishabh Testing and calibration Laboratory is going for NABL accreditation (National Accreditation board for Testing and Calibration Laboratories) as per ISO/IEC 17025:2005, for its calibration facilities in the Electro-technical field.
