Getting the Most Out of Your Rupture Disc - For Optimum Rupture Disc Performance, Pay Attention to Installation, Operation and Maintenance - Dean Miller - Rupture disc devices provide overpressure protection for a variety of storage and process vessels and equipment. The objective of the rupture disc is to maintain a leak tight seal and be a passive bystander until called upon to relieve excess pressure. While this is generally the case, there are times when rupture disc performance can be adversely affected through various installation, operation and maintenance practices. This article reviews some of these practices, real-life observed consequences, and corrective or preventative measures that can improve rupture disc performance - from Fike Corporation.

Rupture Disc Terminology and Concepts - A comprehensive list here.
A Structured Method for Proper Selection of Rupture Disks for Safety Relief in Ammonia Plants - Jeff Scoville and Alan Wilson - Proper selection of a rupture disk is more than performing sizing calculations to make sure it is adequatelysized for the emergency event. Criteria such as operating pressure and temperature, material selection, gasor liquid service, etc. must be evaluated to determine the best disk type for the application. The cost of notevaluating such criteria can be significant to operations if the ammonia plant has excessive “nuisance” failures of an improperly specified rupture disk. This paper will present a structured step-by-step method for determining the appropriate rupture disk type for an application - from Oseco Inc.
The Use of Certified KR for Rupture Disks - Jeff Scoville - The ASME Section VIII, Division 1, 1998 code established a new code symbol stamp forrupture disks in 1999 called “UD”. While the Code recognized rupture disks as acceptable pressure relief devices prior to this revision, there was no formal process for product certification. Very few manufacturers had performed flow testing of their products, therefore the methodologies for sizing relief systems reflected in the ASME Code and API Recommended Practices (RP) were estimates at best. The new UD stamp now requires any product carrying the stamp to be flow tested at an ASME PTC-25 accepted flow laboratory in the presence of a representative from the National Board of Boiler and Pressure Vessel Inspectors. Results of the flow testing are communicated directly to the user via the certified flow resistance factor (KR) and minimum net flow area (MNFA) stamped on the disk tag. These values are also published in the National Board Red Book, which also covers relief valves.
Rupture Disc Specification
Rupture Disc Specification - A simple way of understanding and comparing rupture disk specifications is to recognise the definition given by AS1358 for PERFORMANCE TOLERANCE.

Rupture Disc Sizing
Rupture Disc Sizing - The objective of this bulletin is to provide detailed guidance for sizing rupture discs using standard methodologies found in ASME Section VIII Div. 1, API RP520, and Crane TP-410 - from Fike Corporation.

Rupture Disc - Pressure Relief Valve (PRV) Combinations
Best Practices for Rupture Disc (RD) - Pressure Relief Valve (PRV) Combinations - Rupture discs, also known as bursting discs, are commonly used to isolate pressure relief valves from corrosive or otherwise fouling service on the process side and/or the discharge side. This paper will discuss the various code requirements, the practical aspects, and recommended best practices. The basis of most of the discussion comes from ASME Section VIII Division 1; however similar requirements and/or principals are found in API RP520 and EN ISO 4126-3 - from Fike Corporation.
