What are standards and specifications?

Standards and specifications are documents that describe and/or recommend a set of rules and conditions for how materials and products should be manufactured, defined, measured, or tested.

What is ASTM grade?

What are ASTM Grades? ASTM standards define the specific manufacturing process of the material and determine the exact chemical composition of pipes, fittings and flanges, through percentages of the permitted quantities of carbon, magnesium, nickel, etc., and are indicated by “Grade”.

What does Standard mean?

1 : something established by authority, custom, or general consent as a model, example, or point of reference the standard of the reasonable person. 2 : something established by authority as a rule for the measure of quantity, weight, extent, value, or quality. 3 : the basis of value in a monetary system.

Is ASME a code or standard?

ASME code – also known as ASME Boiler & Pressure Vessel Code or BPVC – is the standard that regulates the design, development and construction of boilers and pressure vessels utilized in a variety of industries.

What are the three forms of specification?

In every construction project, there are three types of construction specifications. The three types of construction specifications are prescriptive, performance, and proprietary.

What are the 3 most important qualities of written code?

Clarity of code. Clarity of design. Clarity of purpose. You must understand — really understand — what you’re doing at every level.

What is standard quality?

Quality Glossary Definition: Standard. Quality standards are defined as documents that provide requirements, specifications, guidelines, or characteristics that can be used consistently to ensure that materials, products, processes, and services are fit for their purpose.

Are ASME standards mandatory?

Are standards mandatory? … ASME cannot force any manufacturer, inspector, or installer to follow ASME standards. Their use is voluntary. Standards become mandatory when they have been incorporated into a business contract or incorporated into regulations.

What’s the difference between code and standard?

One way of looking at the differences between codes and standards is that a code tells you what you need to do, and a standards tells you how to do it. A code may say that a building must have a fire-alarm system. The standard will spell out what kind of system and how it must work.

Why are codes and standards important?

Compliance. Codes and Standards draw a “line in the sand” requiring compliance by vendors, engineering contractors and owners regarding design, fabrication and operation of equipment. Codes and Standards also allow personnel to expand their knowledge base by use of the documents.

What is an example of standard?

What is an equipment specification?

Equipment specifications are written documents or manuals that stipulate the method of production capacity, power requirement, fabrication methods and other finer details of the equipment that makes it apt for use. An engineer must have a clear understanding of equipment specifications to avoid equipment breakages.

What is ASTM stands for?

the American Society for Testing and MaterialsThe letters “ASTM” used to stand for the American Society for Testing and Materials.

What is API standard code?

API specifications are recommended practices developed based on insight gleaned from the petroleum and petrochemical industry – which makes sense given that API stands for American Petroleum Institute. API standards are intended to encourage safety in the oil and natural gas industries specifically.

What is a standards document?

Standard document is defined as “a document approved by a recognized body that provides, for common and repeated use, rules, guidelines, or characteristics for products or related processes and production methods, with which compliance is not mandatory.

ASME has been defining piping safety since 1922. ASME B31. 3 contains requirements for piping typically found in petroleum refineries; chemical, pharmaceutical, textile, paper, semiconductor, and cryogenic plants; and related processing plants and terminals.

What is meant by coding standards?

Coding standards are collections of coding rules, guidelines, and best practices. Using the right one will help you write cleaner code.

What is a basic standard?

Basic Standards are the unaltered standards which are used over for a longer period of time and do not reflect current conditions. These standards are not useful from the cost of control point of view as they consider only fixed costs. … It is only a technique which is used with the intention of controlling cost.

What does ISO standard for?

ISO (International Organization for Standardization) is an independent, non-governmental, international organization that develops standards to ensure the quality, safety, and efficiency of products, services, and systems. … ISO standards are in place to ensure consistency.

What is difference between ASME and ASTM?

Basically ASTM creates the material specifications and standard test methods to determine compliance. ASME selects those ASTM materials which will perform adequately in boiler or pressure vessel service and accepts them with stated limitations.
