Question: What Is The Difference Between A Specification And A Standard?

Why do we need codes and standards?

The main purpose of codes is to protect the public by setting up the minimum acceptable level of safety for buildings, products and processes.

Standards allow for interchangeability of parts, system interoperability, and they ensure quality, reliability and safety..

What is ASME Code for piping?

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.

How do you write a specification?

Here are five steps you can follow to write an effective SRS document.Create an Outline (Or Use an SRS Template) Your first step is to create an outline for your software requirements specification. … Start With a Purpose. … Give an Overview of What You’ll Build. … Detail Your Specific Requirements. … Get Approval for the SRS.

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.

What are quality standards?

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.

What is code in piping?

Piping codes defines the requirements of design, fabrication, use of materials, tests and inspection of pipes and piping systems – what you need to do. A code has a limited jurisdiction defined by the code. A code is not law, but can be adopted into law.

What is difference between code and standard and specification?

Codes are generally accepted sets of rules that tell you what you need to do. Standards provide the “how to” of executing codes. Specifications, unlike codes or standards, outline the requirements of a specific company or product.

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 the difference between a standard and a guideline?

As nouns the difference between standard and guideline is that standard is a level of quality or attainment while guideline is a non-specific rule or principle that provides direction to action or behaviour.

Because specifications are an integral part of the Contract Documents, they are considered to be legal documents, and should therefore be comprehensive, accurate, and clear. Specification writing has two principal objectives: to define the scope of work and to act as a set of instructions.

What is the different ASME 31 Code for Pressure Piping?

B31 Code for pressure piping, developed by American Society of Mechanical Engineers – ASME, covers Power Piping, Fuel Gas Piping, Process Piping, Pipeline Transportation Systems for Liquid Hydrocarbons and Other Liquids, Refrigeration Piping and Heat Transfer Components and Building Services Piping.

What is the difference ASME b31 Code for Pressure Piping?

3 ,both Codes spell out thier intended scopes and their rules are “valid” for the intended scope. ASME B31 Pressure Piping Codes are “voluntary consensus Codes”. When a local building Code (which is the law -jurisdiction ) requires the use of one of the B31 Codes, Only then does it have “the force of law”.

What is meant by specification?

A specification often refers to a set of documented requirements to be satisfied by a material, design, product, or service. A specification is often a type of technical standard. … The word specification is broadly defined as “to state explicitly or in detail” or “to be specific”.

What are the types of specification?

Four Types of “Specifications”Product Specification: This describes a manufacturer’s product and its performance without consideration for a particular building. … Project Specification: This describes an architect’s design and performance requirements for a particular building. … Master Specification: … Guide Specification:

What is ASTM pipe?

ASTM A53 is a carbon steel alloy, used as structural steel or for low-pressure plumbing. … ASTM A53 pipe is sized according to the nominal pipe size (NPS) system. It is commonly available with national pipe thread ends or with plain cut ends. It can be used for steam, water, and air conveyance.
