Certifications & Standards

LaGrange Products will meet the certification needs and standards necessary to complete your project, and we will meet every standard and inspection necessary to certify your job.

American Society of Mechanical Engineers (ASME)

The American Society of Mechanical Engineers is a not-for-profit organization that was formed in 1880 and currently boasts over 120,000 members. Acting as an engineering society, ASME sets codes and standards for mechanical devices, including the boiler and pressure vessels LaGrange Products produces. The Boiler and Pressure Vessel Code is the largest ASME standard, and governs the design, fabrication and inspection of those vessels.

ASME "U" & "UM" Stamps

The American Society of Mechanical Engineers is a not-for-profit organization that governs and sets codes and standards for pressure vessel design, fabrication and inspection. LaGrange Products complies with the codes and standards of the ASME, and is authorized to apply the "U" or "UM" stamps to the vessels we produce. A "U" stamp signifies a standard pressure vessel, and a "UM" stamp signifies a miniature pressure vessel. The United States and Canada, as well as over 100 other countries, accept and regulate their pressure vessels to ASME codes and standards.

National Board "R" Stamp

Since 1919, the National Board of Boiler and Pressure Vessel Inspectors has overseen the adherence of codes covering construction, installation, repair, maintenance, alteration and inspection of boilers and pressure vessels. In 1975, to create a uniform quality standard, the Board instituted a Repair "R" Stamp and Certificate for Authorization to qualified manufacturers performing repairs on boilers and pressure vessels. This "R" stamp certifies that the repairs LaGrange Products makes to your company’s ASME pressure vessels follow the National Board Inspection Code.

Department of Transportation (DOT)

The Department of Transportation was formed in 1966 by an act of Congress, and as a federal cabinet department, governs all aspects of transportation in the United States . Areas of DOT’s license and certification coverage include aviation, highways and bridge inspections, railroads, maritime travel, pipeline and hazardous materials movement and research. The pressure vessels LaGrange Products produces, to serve the above categories, must always conform to DOT specifications.

Australia Standard (AS 1210)

The Australia Standard, or AS 1210, is the Australian standard for pressure vessel design. Created in 1997, it specifies the requirements for materials, design, purchasing, manufacture, testing, inspection, certification and registration, shipment, and maintenance and repairs of pressure vessels in Australia .

Canadian Registration Number (CRN)

Pressure vessels, boilers and fittings constructed for use in Canada require a special registration for each Province the vessels will be used in. A Canadian Registration Number is issued to that specific vessel type once it has been inspected and registered by qualified Provincial engineers.

American Bureau of Shipping (ABS)

The American Bureau of Shipping was formed in 1862 as a means of qualifying and certifying ship captains. Since that time, ABS has evolved into a classification society, developing construction and safety standards (referred to as ABS Rules) concerning the design, construction and operation of new and existing vessels, as well as marine-related onshore and offshore structures and facilities.

International Organization for Standardization (ISO 9001:2008) Shop

The International Organization for Standardization is the world’s largest developer and publisher of international standards. It consists of a global family of standards governing the quality management systems of 159 countries. A company wishing certification in compliance with ISO must be audited by both an external certification body as well as that company’s trained internal staff. The never-ending goal of LaGrange Products is to achieve a continual process of review and assessment, and to always be on the lookout for better ways to design, purchase, manufacture and ship our company’s pressure vessels, thus assuring our customers of our ability to provide quality vessels in a consistent manner.

Pressure Equipment Directive (PED)

The European Union has its own specific standards for the design and manufacture of pressure vessels and equipment. The current PED has been in effect since 2002, and was formed to eliminate technical trade barriers and to standardize the laws between the countries making up the EU and the European economic trading area. The PED is one of a series of technical directives covering everything from medical devices and electrical equipment to pressure vessels used in industries as diverse as energy production, pharmaceutical, chemical, plastics and rubber, and the food and beverage industries.

National Board of Boiler & Pressure Vessel Inspectors

The National Board of Boiler and Pressure Vessel Inspectors oversees the adherence of codes covering construction, installation, repair, maintenance, alteration and inspection of boilers and pressure vessels. It was created in 1919 to represent government agencies across North America , and is the only standard recognized worldwide for pressure vessel in-service inspection, repairs and alterations. The Board offers an extensive training program for third-party inspectors and industry professionals, maintains a testing laboratory, and investigates pressure vessel accidents and code compliance issues.
