  1. 1. STANDARDS & SPECIFICATIONS
  2. 2. STANDARD <ul><li>A basis for comparison, a criterion; measure </li></ul><ul><li>--The New American Webster Dictionary (1972) </li></ul><ul><li>Something that is established by authority, custom or general consent as a model or example to be followed. </li></ul><ul><li>Something established for use as a rule or basis of comparison in measuring or judging capacity, quantity, content, extent, value, quality, etc. </li></ul><ul><li>Documented agreements containing specifications or other precise criteria to be used consistently as rules, guidelines, or definitions of characteristics, to ensure that materials, products, processes and services are fit for their purpose -- ISO </li></ul>
  3. 3. Benefits of Standards <ul><li>Standard facilitates communication and prevent misunderstanding. </li></ul><ul><li>Production Efficiency is enhanced by standardization which relates to time saving also. </li></ul><ul><li>Standards make parts interchangeability possible and as a result mass production is possible. </li></ul><ul><li>Standardization allows enhanced competition. </li></ul><ul><li>Standards can be used in marketing strategy to promote purchase of products that meet nationally recognized requirements, especially, when conformance is backed by a certification program. </li></ul><ul><li>Public welfare also gets benefited. Standards are used to protect health, environmental quality and promote safety </li></ul>
  4. 4. <ul><li>Company standards- </li></ul><ul><li>These standards are useful to the company’s design, development, production, purchasing, and quality control departments. These standards may be those developed by the company itself or developed by some other organization(s) and adopted by the company as its own standards. </li></ul><ul><li>Industry Standards- </li></ul><ul><li>These standards are typically developed by a trade association or professional society. For example, American Chemical Society has for many years maintained specifications for chemical reagents. </li></ul>Levels of Standard
  5. 5. <ul><li>Government Standards- </li></ul><ul><li>These are standards either developed by the government or developed by some other organization (s)and adopted by the government. The government standards generally tend to be related to safety or well being of the people. </li></ul><ul><li>Full Consensus Standards- </li></ul><ul><li>These are standards developed by the representatives of all sectors, such as industry, consumer, government, academia, who have an interest in use of these standards either as a producer or consumer. </li></ul>Levels of Standard
  6. 6. Types of Standard <ul><ul><li>1 st set of Classification </li></ul></ul><ul><ul><li>Test Method </li></ul></ul><ul><ul><li>Specification </li></ul></ul><ul><ul><li>Practice </li></ul></ul><ul><ul><li>Terminology </li></ul></ul><ul><ul><li>Guide </li></ul></ul><ul><ul><li>Classification </li></ul></ul><ul><li>2 nd set of Classification </li></ul><ul><li>Product </li></ul><ul><li>Process </li></ul><ul><li>Service </li></ul><ul><li>Performance </li></ul><ul><li>Management systems </li></ul>Different Sets of Classification are available- <ul><li>3 rd set of Classification </li></ul><ul><li>Mandatory </li></ul><ul><li>Voluntary </li></ul>
  7. 7. Types of Standard <ul><li>Test method: a definitive procedure for the identification measurement, and evaluation of one or more qualities, characteristics, or properties of a maternal, product, system, or service that produces a test result. </li></ul><ul><li>Specification: a precise statement of a set of requirements to be satisfied by a material, product, system, or service that indicates the procedures for determining whether each of the requirements is satisfied. They often are given as numerical requirements with appropriate units and within reasonable limits </li></ul><ul><li>Practice: a definitive procedure for performing one or more specific operations or functions that close not produce a test result, these are not down graded tests. They include statistical procedures, writing statements on precision, and selecting, installing, and operating equipment. </li></ul>ASTM develops six types of full consensus standards-
  8. 8. Types of Standard <ul><li>Terminology: a document comprising definitions of terms, descriptions of terms, and explanations of symbols, abbreviations, or acronyms. </li></ul><ul><li>Guide: a series of options or instructions that do not recommend a specific course of action. Guides suggest approaches, offer guidance for a procedure, increase awareness of available techniques and provide information regarding evaluation and standardization. </li></ul><ul><li>Classification: a systematic arrangement or division of materials, products, systems, or services into groups based on similar characteristics such as origin, composition, properties, or use. Examples include fiber and yarn classification charts used in beginning textiles classes. </li></ul>
  9. 9. ORGANISATIONS <ul><li>Introduction: </li></ul><ul><li>In an industry with so many segments ,each with its own interests, communicating quality requirements and supplying goods of the appropriate quality level are difficult. As a result individuals and companies with similar interests have formed professional and trade organizations. </li></ul><ul><li>These organizations focus their efforts on identifying and defining terms, developing consistent practices within the field for describing and evaluating materials and process, encouraging fair trade practices, developing technological advances to maintain competition in the world market. </li></ul>
