This document presents key elements and the philosophy of the control chart approach, and identifies a wide variety of control charts (including those related to the Shewhart control chart, those stressing process acceptance or online process adjustment, and specialized control charts).

This document gives guidance on the uses of acceptance control charts and establishes general procedures for determining sample sizes, action limits and decision criteria. An acceptance control chart should be used only when:a) the within subgroup variation is in-control and the variation is estimated efficiently;b) a high level of process capability has been achieved.

This document describes ways of applying regular variables control charts to short runs and small mixed batches where the sample size for monitoring is restricted to one. It provides a set of tools to facilitate the understanding of sources of variation in such processes so that the processes can be bettermanaged.

ISO 11462 provides guidelines for the implementation of a statistical process control (SPC) system. These guidelines are aimed primarily at increasing production efficiency and inherent capability, and reducing interval andcost.This part of ISO 11462 provides elements to guide an organization in planning, developing, executing, and/or evaluating a statistical process control system.

This European Standard specifies the safety requirements and test methods for pushchairs and prams, designed for the carriage of one or more children, up to 15 kg each and up to 20 kg for any integrated platform on which a child can stand.This European Standard does not cover toys, baby carriers fitted with wheels; pushchairs and prams propelled by a motor and pushchairs and prams designed for children with special needs.Where a pushchair or pram or any part of the pushchair or pram has several functions or can be converted into another function it is due to comply with relevant standard(s).

This European Standard specifies requirements and testing procedures for high security locks used in distributed systems, which are mainly used in secure storage units. A distributed system, as per the definition of this European Standard, is a system with components connected by a transmission system, wired or wireless. Also, a token represents a distributed system as of a transmission distance of 15 cm or more.The present standard responded to the state of the art requirements for distributed systems when it was written down. However it is mandatory that the standard has to be revised with a relatively high frequency of 3 years or less, as the research in the area of cryptography and relevant attacks evolve with high speed as well as the referenced standards. As the general regulations of EN 1300 don’t require such a high frequency of updating, it is recommended to separate the standards.

This document specifies the requirements for inspection and maintenance of LPG cylinder valves, either manually operated or self-closing, for reuse. It applies when the valve is either inspected or refurbished at the time of periodic inspection of the cylinder.This document may also be applied at any other time, for example, when maintenance of the valve is necessary.

This document describes investigations required for in situ preservation and monitoring of archaeological sites. It sets out the main parameters used to assess the state of preservation of archaeological materials and evaluate the preservation conditions of archaeological deposits and provides a framework for monitoring sites. A “decision making” framework is included to help readers make appropriate knowledge-based choices.The procedures described are appropriate for both terrestrial and underwater archaeological sites.The informative annexes relate primarily to terrestrial sites; for detailed technical guidance on investigating and monitoring marine sites, see sasmap.eu [6, 7].NOTE Marine sites include all underwater sites and those in the intertidal zone.

The delivered ISO International Standard gives guidelines for the preparation of cheese samples for physical and chemical testing.

1.1 PurposeThis document establishes the minimum requirements for the qualification and certification of personnel performing nondestructive testing (NDT), nondestructive inspection (NDI), or nondestructive evaluation (NDE) in the aerospace manufacturing, service, maintenance and overhaul industries. For the purposes of this document, the term NDT will be used and will be considered equivalent to NDI and NDE.In Europe, the term "approval" is used to denote a written statement by an employer that an individual has met specific requirements and has operating approval. The term "certification" as defined in 3.2 is used throughout this document as a substitute for the term "approval". Except when otherwise specified in the written practice, certification in accordance with this document includes operating approval.1.2 ApplicabilityThis document applies to personnel using NDT methods to test and/or accept materials, products, components, assemblies or sub-assemblies. This document also applies to personnel: directly responsible for the technical adequacy of the NDT methods used, who approve NDT procedures and/or work instructions, who audit NDT facilities, or who provide technical NDT support or training.This document does not apply to individuals who only have administrative or supervisory authority over NDT personnel or to research personnel developing NDT technology for subsequent implementation and approval by a certified Level 3. Personnel performing specialized inspections using certain direct readout instruments as determined by a Level 3 certified in the method, do not require qualification or certification to this document.1.2.1 ImplementationThis document addresses the use of a National Aerospace NDT Board (NANDTB). NANDTBs are only used as specified per Annex C and it is not mandatory to have such a board for compliance with this document. Personnel certified to previous revisions of NAS 410 or EN 4179 need not recertify to the requirements of this document until their current certification expires.1.3 Methods1.3.1 Common methodsThis document contains detailed requirements for the following common NDT methods:Eddy Current Testing (ET)Liquid Penetrant Testing (PT)Magnetic Particle Testing (MT)Radiographic Testing (RT)Thermographic Testing (IRT)Ultrasonic Testing (UT)1.3.2 Other methodsWhen invoked by engineering, quality, cognizant engineering organization or prime contractor requirements, this document applies to other current and emerging NDT methods used to determine the acceptability or suitability for intended service of a material, part, component, sub-assembly or assembly. Such methods can include, but are not limited to, acoustic emission, neutron radiography, leak testing, holography, and shearography. The requirements for personnel training, experience, and examination for these other methods are established in accordance with 6.4 and are documented by the employer.
