Compliance of technical regulations 3

A technical standard is an established norm or requirement for a repeatable technical task which is applied to a common and repeated use of rules, conditions, guidelines or characteristics for products or related processes and production methods, and related management systems practices. A technical standard includes definition of terms; classification of components; delineation of procedures; specification of dimensions, materials, performance, designs, or operations; measurement of quality and quantity in describing materials, processes, products, systems, services, or practices; test methods and sampling procedures; or descriptions of fit and measurements of size or strength.

It is usually a formal document that establishes uniform engineering or technical criteria, methods, processes, and practices. In contrast, a custom, convention, company product, corporate standard, and so forth that becomes generally accepted and dominant is often called a de facto standard.

A technical standard may be developed privately or unilaterally, for example by a corporation, regulatory body, military, etc. Standards can also be developed by groups such as trade unions and trade associations. Standards organizations often have more diverse input and usually develop voluntary standards: these might become mandatory if adopted by a government (i.e., through legislation), business contract, etc.

The standardization process may be by edict or may involve the formal consensus of technical experts.

Types

The primary types of technical standards are:

• A standard specification is an explicit set of requirements for an item, material, component, system or service. It is often used to formalize the technical aspects of a procurement agreement or contract. For example, there may be a specification for a turbine blade for a jet engine that defines the exact material and performance requirements.
• A standard test method describes a definitive procedure that produces a test result. It may involve making a careful personal observation or conducting a highly technical measurement. For example, a physical property of a material is often affected by the precise method of testing: any reference to the property should therefore reference the test method used.
• A standard practice or procedure gives a set of instructions for performing operations or functions. For example, there are detailed standard operating procedures for operation of a nuclear power plant.
• A standard guide is general information or options that do not require a specific course of action.
• A standard definition is formally established terminology.
• Standard units, in physics and applied mathematics, are commonly accepted measurements of physical quantities.

Geographic levels

When a geographically defined community must solve a community-wide coordination problem, it can adopt an existing standard or produce a new one. The main geographic levels are:

• National standard: by National standards organizations. For example, Telecommunications Industry Association standards.
• Regional standard: see standards of the Regional standards organizations. For example, CEN standards.
• International standard: see International standards organizations Example, ISO and ASTM International.

National/Regional/International standards is one way of overcoming technical barriers in inter-local or inter-regional commerce caused by differences among technical regulations and standards developed independently and separately by each local, local standards organisation, or local company. Technical barriers arise when different groups come together, each with a large user base, doing some well established thing that between them is mutually incompatible. Establishing national/regional/international standards is one way of preventing or overcoming this problem. To further support this, the WTO Technical Barriers to Trade (TBT) Committee published the “Six Principles” guiding members in the development of international standards.
