Codes and Standards

CODES AND STANDARDS

As seen earlier that basic NDT methods are VT,MT,RT,UT,PT

In order to meet the standard requirement all NDT procedure must be carried out as per standard procedure to obtain desired test results. These procedures are derived from applicable code and standards.

Standards , Codes and Specifications

A code is a set of rules, regulations, strictures, minimum requirements for “ethical conduct”. It is a group of general rules or systematic procedures for design, fabrication, installation, and inspection that are adopted by legal jurisdiction and made into law.

Codes are intended to set forth engineering requirements deemed necessary for safe design and manufacturing of critical machinery and components.

Code has the force of law, unlike standards that are voluntarily accepted guidelines which become mandatory only when incorporated into a business contract.

 

Standards

Standards are the documents, prepared by a professional societies or committees, which are believed to be efficient engineering practices and which contain mandatory requirements. The users are responsible for correct application of the same. Compliance with the standard does not itself confer immunity from legal obligations.

ASME BPVC CODE

ASME Code BPVC (Boiler and Pressure vessel code) is a code of construction for boilers and pressure vessels formulated by ASME. It is a manufacturer’s code and is reviewed every year hence making it a live and up to date code.

ASME BPVC List of Sections

SECTION I

Rules for construction of Power Boilers

SECTION II

Materials

SECTION III

Rules of construction for Nuclear facilities Components

SECTION IV

Rules of construction for heating boilers

SECTION V

Non Destructive Testing

SECTION VI

Rules for care and operation of heating boilers

SECTION VII

Guidelines for care of power boilers

SECTION VIII
