ASME Certification Mark
The ASME Certification Mark, which is regarded as the hallmark of acceptance and certification, is used to indicate that the stamped items conform to the ASME Boiler and Pressure Vessel Code, as well as the Bioprocessing Equipment Standard, and Reinforced Thermoset Plastic Corrosion-Resistant Equipment Standard. Utilization of the Certification Mark is a means of complying with the laws and regulations in nearly all U.S. States and Canadian Provinces. In addition, it has been estimated that over 100 countries accept the ASME BPVC as a means of meeting their government safety regulations
Allows the manufacture of pressure vessels at the specific location and sites of the owner of the certificate. The U Code Symbol on a vessel is used to confirm that the stamped item is in conformance to the latest edition of the Code and that the pressure vessel has been designed and manufactured in accordance with ASME.
The National Board offers the Certificate of Authorization and R symbol stamp for the repair and/or alteration of boilers, pressure vessels, and other pressure-retaining items. Requirements are described in NB-415, Accreditation of R Repair Organizations. The manufacturer owning this stamp must have and maintain an inspection agreement with an authorized inspection agency, have a written quality system that complies with the requirements of the current edition of the National Board Inspection Code (NBIC) and includes the expected scope of activities, and have the current edition of all three parts of the NBIC.
The NB mark is used by manufacturers to identify items registered with the National Board. It is also used by pressure relief device manufacturers and assemblers to identify pressure relief devices that have been certified by the National Board in accordance with NB-501, National Board Certification of Pressure Relief Devices. With this system, any serial number registered with the National Board can be looked up to identify specs and the manufacturer.
The American Institute of Steel Construction (AISC) Certification sets the quality standard for the steel industry and is the most recognized national quality Certification program for the structural steel industry. Companies that are AISC certified have been through a rigorous initial evaluation, and are subject to annual reviews for quality and safety purposes.
