The quality assurance model

11/30/2009

Introduction

This International Standard is one of three International Standards dealing with quality system requirements that can be used for external quality assurance purposes. The quality assurance models, set out in the three International Standards listed below; represent three distinct forms of quality system requirements suitable for the purpose of a supplier demonstrating its capability, and for the assessment of the capability of a supplier by external parties.

a)      IS0 9001, Quality systems- Model for quality assurance in design, development, production, installation and servicing for use when conformance to specified requirements is to be assured by the supplier during design, development, production, installation and servicing.

b)      IS0 9002, Quality systems -Model for quality assurance in production, installation and servicing for use when conformance to specified requirements is to be assured by the supplier during production, installation and servicing.

c)      IS0 9003, Quality systems -Model for quality assurance in final inspection and test for use when conformance to specified requirements is to be assured by the supplier solely at final inspection and test. It is emphasized that the quality system requirements specified in this International Standard, IS0 9002 and IS0 9003 are complementary (not alternative) to the technical (product) specified requirements. They specify requirements which determine what elements quality systems have to encompass, but it is not the purpose of these International Standards to enforce uniformity of quality systems. They are generic and independent of any specific industry or economic sector. The design and implementation of a quality system will be influenced by the varying needs of an organization, its particular objectives, the products and services supplied, and the processes and specific practices employed. It is intended that these International Standards will be adopted in their present form, but on occasions they may need to be tailored by adding or deleting certain quality system requirements for specific contractual situations. IS0 9000-l provides guidance on such tailoring as well as on selection of the appropriate quality assurance model, viz. IS0 9001, IS0 9002 or IS0 9003.

K Factor / Set Back

Set Back (Applicable To Closed Angles Only).  This is the deduction made in the length of a flat pattern development corresponding to the amount of material saved by bending around a radius instead of a sharp corner.
