Statistical process control (SPC) concerns the use of statistical techniques and statistical or stochastic control algorithms to achieve one or more of the following objectives: These guidelines give the elements for implementing an SPC system to achieve these objectives. The common economic objective of statistical process control is to increase good process outputs produced for a given amount of resource inputs. This part of ISO 11462 specifies SPC system guidelines for use This part of ISO 11462 considers the complete industrial supply chain. It describes some essential statistical methods that can be used to continuously improve capability or performance and stability of production processes. The bottom line is that production processes are controlled economically, promptly and effectively. As a result, a predefined level of quality can be realised. The improvement of stability and performance or capability of the production processes effectively reduces waste and machine downtime or increases productivity. If defective production parts are found in a random sample, they can be sorted out and, if necessary, further measures can be initiated.

This document specifies the characteristics, performance requirements and test methods for portable fire extinguishers. Reference to the suitability of an extinguisher for use on gaseous fires (Class C fires) are at the manufacturer’s discretion but are applied only to powder type extinguishers which have gained a Class B or Class A and Class B rating. Suitability of extinguishers for use on Class D fires (fires involving flammable metals) is outside the scope of this document in respect of test fires. However, extinguishers claiming Class D suitability are covered in all other respects by the requirements in this document for powder extinguishers. It is considered hazardous for powder and carbon dioxide fire extinguishers to be used on Class F fires. For this reason, powder and carbon dioxide fire extinguishers are excluded for conformance with regard to Class F in this document. NOTE The extinction of a metal fire presents a situation so specific (in terms of the metal itself, its form, the configuration of the fire etc.) that it is not possible to define a representative standard fire for the purposes of testing. The efficiency of extinguishers on Class D fires is established on a case by case basis.
