This publication also includes a listing of organizations which have received a National Board certificate of authorization for the use of the “VR” repair symbol stamp in accordance with the National Board -23 and NB- 514, Accreditation of VR Repair Organizations. Inspection Code publication, NB This publication is divided into a series of listings as found in the table of contents. If using a portable document file (pdf) viewer, the user of this document may also use the bookmarks and search features of the this document. Companies which no longer hold certifications or device design certifications viewer to navigate which are no longer in production are not listed. Information on these devices may be obtained by contacting the National Board Pressure Relief Department. This publication is updated weekly and is available free of charge from the National Board Web site, www.nationalboard.org. The capacity rating values listed were determined from tests of samples of the relevant pressure relief device type at a National Board accepted testing laboratory under ideal conditions. Such capacities are certified only for the conditions under which obtained. Since the listed rating values were determined under atmospheric -pressure pressure discharge conditions, the calculated capacities may not be valid when discharge back conditions exist. The National Board has not tested each production device and makes no certification regarding its capacity, manufacturer, or application. Installation, operating conditions and manufacturer’s mendations must be considered in selecting a pressure relief device for service. recom -18 as accurate and complete as Every effort has been made to make the information contained within NB possible.

3 Table of Contents ONAL BOARD PRESSURE RELIEF DEVICE CERTIFICATION NATI ADMINISTRATIVE REQUIREMENTS 1.0 INTRODUCTION The National Board Pressure Relief device certification program was developed in the mid- 1930s in an effort to enhance safety to the industry and to the general public. At that time, when jurisdictional authorities expressed concern about relieving capacities, the National Board sponsored tests at The Ohio State University to compare the stamped and actual relieving capacities. They found large differences which prompted the National Board’s membership to resolve that safety valves should be standards and performance must be demonstrated by tests. At the request of constructed to recognized the National Board, the American Society of Mechanical Engineers (ASME) appointed a special committee on safety valve requirements to cooperate with the National Board and developed construction requirements, quality standards and testing procedures. SCOPE 2.0 This National Board program provides for the certification of pressure relief device designs and 2.1 the accreditation of organizations who manufacture or assemble these devices. Accredited organizations are issued a certificate of authorization to apply the National Board "NB” symbol to devices of certified desi gns. 2.2 Technical requirements applied by this program to pressure relief devices are contained in standards called "construction codes.” Abbreviations for these codes are listed below: Construction Code Code Section I ASME Boiler & Pressure Vessel Code (B&PVC) Section I ASME (B&PVC) Section III III IV ASME (B&PVC) Section IV SME (B&PVC) Section VIII VIII A Organizations which have met the program requirements and have paid the proper 2.3 administrative fees will be granted permission to use the National Board’s "NB” mark on devices to denote certification by the National Board of the pressure relieving device design. 3.0 PROGRAM RULES AND PROCEDURES ADMINISTRATION 3.1 Organizations desiring National Board certification and permission to use the "NB” mark shall apply to the National Board on forms available from the Pressure Relief Department. Manufacturers (as defined by the construction code) must supply all information as requested. Assemblers (as defined by the construction code) must indicate the valve manufacturer’s name and valve type to be considered for certification. QUALITY SYSTEM REQUIREMENTS 3.2 Each applicant shall have and maintain a quality system which shall establish that all of these rules and administrative procedures and applicable construction code requirements, including material control, fabrication, machining, welding, examination, setting, testing and inspection, will be met.

4 Table of Contents A written description of the system the applicant will use shall be available for review and shall contain, as a minimum, the features set forth by the construction code. The system shall include a description of the controls to ensure that the "NB” mark is applied to devices which have been may be brief or voluminous, depending upon certified in accordance with 3.3. This description the circumstances, and shall be treated confidentially. A review for acceptance of the applicant’s quality control system will be performed by a representative of the National Board. The review will include a demonstration of the implementation of the provisions of the applicant’s quality system. Sample production devices will be selected for testing of performance and capacity. Each applicant shall issue a controlled copy of the accepted quality system written description to the National Board. Except for changes which do not affect the quality system, revisions to the written description shall not be implemented until such revisions are accepted at any time by the National Board. CAPACITY CERTIFICATION OF 3.3 DEVICE DESIGNS DESIGN REVIEW (MANUFACTURERS ONLY) 3.3.1 Before a design is tested by a manufacturer, it will be reviewed by the National Board to determine that all applicable mechanical and material requirements of the construction code have been considered and incorporated into the design as necessary. No testing for device certification will be performed on devices which do not meet these requirements. INITIAL TESTING (MANUFACTURERS ONLY) 3.3.2 After completion of the design review per 3.3.1, tests of devices specified by the construction code shall be conducted to determine the certified rating which will be applied to the production device. Agreement shall be reached between the manufacturer and the National Board as to the number, sizes and set pressures of the devices to be tested. These tests will be performed for new designs or when an existing design is modified. Modifications of designs which affect the flow path, lift or performance characteristics must be reviewed by the National Board. Provisions for notifying the National Board of design changes shall be included in the applicant’s quality system. PRODUCTION TESTING 3.3.3 An applicant who has met the requirements of 3.1 and 3.2 may be granted permission to apply the National Board "NB” mark to production pressure relief devices (of designs for which initial testing has been completed) provided the following tests are successfully completed. This permission shall expire on the fifth anniversary of the date it is initially granted. This permission may be extended for 6 year periods if the following tests are successfully repeated within the 6 month period before expiration. (1) Two sample production pressure relief devices of a size and capacity within the capacity of a National Board accepted laboratory shall be selected by a National Board representative. (2) Operational and capacity tests shall be conducted in the presence of a National Board representative at a National Board accepted laboratory.

125 Table of Contents LISTING OF CERTIFIED DEVICE TYPES This publication includes certification tables for each design type presently certified. These tables are listed in alphabetical order according to the manufacturer. The following is an example and brief description of the listings and certification tables. 1 The National Board capacity certification number given solely to this valve type. 2 The design series or catalog number is the commercial designation specified by the manufacturer. The Classification of the pressure relief device type as defined in ASME PTC 25. 3 4 This indicates the requirements of the Construction Code used during the initial certification testing. Also listed, the National Board accepted testing laboratory where the testing was performed. In some cases, the device may be certified for additional Code Section as noted in the tables. 5 There are several methods of establishing a certified value used to determine capacity: · the valve average capacity method is used when a manufacturer has only one size and one set pressure to be certified (Flow Capacity, 1 or 3 Valve Method). · the slope (flow factor for liquid) method is used when a manufacturer has one valve design of one size to be certified for a range of set pressures (Flow Capacity, Flow Factor or Flow Capacity, Slope). · the coefficient of discharge method is used when a manufacturer has one design type and wishes to have it certified for a range of sizes and set pressures (Flow Capacity, K). · ). the flow resistance method is used to certify non-reclosing devices such as rupture disk devices (Resistance Factor, K r The quantitative value and applicable unit used to determine device relieving capacity. 6 7 Special provisions of rules, such as Code Cases, and special applications that apply to the device. 8 The test medium listed is the medium that was used during the initial testing. Either air, gas, steam or water could be indicated as the test medium. The certified mediums are the mediums for which the device may be used in service. 9 Set pressure is the valve of increasing inlet static pressure at which a pressure relief device displays an operational characteristic. These 10 characteristics are defined in ASME PTC-25. 11 Blowdown is the difference between actual popping pressure of a pressure relief valve and actual reseating pressure expressed as a percentage of set pressure or in pressure units. This indicates whether the valve has a fixed or adjustable blowdown construction. The NPS (DN) and outlet size or range of sizes of a pressure relief device. 12 For pressure relief valves, flow area is the measured minimum flow area through the valve. For non-reclosing pressure relief devices (e.g. 13 rupture disk devices), flow area is the minimum net flow area to be marked on the device. 14 The orifice diameter is the minimum diameter of the nozzle. 15 The minimum lift is the lift that the valve is expected to have to meet its rated capacity. This column indicates the minimum and maximum set pressures valid for the size, Code Section and medium. 16 This column lists the medium of the certified capacity and is associated with the minimum and maximum set pressures in column 16. 17 18 This column lists the Code Section associated with the minimum and maximum set pressures in column 16.
