Functional Safety: Safety Instrumented Systems for the Process Industry Sector – Part 3: Guidance for the Determination of the Required Safety Integrity Levels
S84.01-2004 is identical to IEC 61511 with one exception. The United States added a “grandfather clause” for existing SISs. The standard integrates the various process safety management approaches used successfully throughout the world. The SIS lifecycle provides a framework for the various activities that are considered essential to the assessment, design, maintenance, inspection, testing, and operation of SIS. A quality management system is also defined to minimize the systematic errors during major project phases, such as:
- Hazard assessment
- Design
- Engineering, Installation, Commissioning, and Validation
- Operating and Maintenance
- Change management
The standard uses a performance metric, the safety integrity level (SIL), to establish order of magnitude levels of analysis, design, diagnostics, testing, and management rigor. The SIL is related to the risk reduction allocated to the SIS to mitigate a specific process risk to a tolerable level.
The Grandfather Clause: S84.01-2004 Part 1 Clause 1y is considered the “grandfather clause” and states the following:
“For existing SIS designed and constructed in accordance with codes, standards, or practices prior to the issuance of this standard (e.g. ANSI/ISA 84.01-1996), the owner/operator shall determine and document that the equipment is designed, maintained, inspected, tested, and operating in a safe manner.”

Chapter 18.1 Measurement Procedures for Crude Oil Gathered from Small Tank by Truck; 2nd Edition, April 1997, Reaffirmed: February 2007
Chapter 18.2 Custody Transfer of Crude Oil from Lease Tanks using alternative measurement methods
Defines the minimum equipment and methods used to determine the quantity and quality of crude oil being loaded from a lease tank to a truck trailer without requiring direct access to a lease tank gauge hatch. Methods and equipment described are grouped by tank zone, trailer zone, and the transition zone between the two.
The equipment used for measurement is dependent on the existing design of the lease equipment, the equipment used to transport the product, or a combination of the two. Some sites may require measurements from multiple zones in order to arrive at an accurate load quantity and quality.
This publication integrates by reference the API Manual of Petroleum Measurement Standards (MPMS) for sampling, temperature determination, gauging, and quality testing into a framework that may be applied during custody transfer of crude oil from lease tanks to a tank truck without requiring direct access to the tank thief gauge hatch. Many of the individual standards have guidelines defining the frequency and tolerances for installation, verification, and calibration of the specified equipment under controlled or ideal conditions allowing for uncertainty within custody transfer requirements. However, with the conditions encountered in many of today’s applications, the installation, verification, and calibration of measurement devices may have higher uncertainties due to the operational characteristics and limited access available at the lease site. In the interest of safety and environmental concerns, these higher uncertainties may still provide acceptable measurement for custody transfer of crude oil from tanks using the defined alternate methods.
The alternate measurement methods discussed in this standard are intended to minimize uncertainty and bias while encouraging consistent measurement and testing practices using existing technologies within API standards. 1st Edition, July 2016

Chapter 19.4 Evaporative Loss Reference Information and Speciation Methodology;
Provides methodology to estimate emissions of individual hydrocarbon species using the total emissions of multicomponent hydrocarbon mixtures (such as crude oils and gasoline) estimated from Ch. 19.1 for fixed-roof tanks, Ch. 19.2 for floating-roof tanks, Ch. 19.5 for marine vessels, and other methods used for total hydrocarbon emission estimates. This process is referred to as speciation.
Speciation of emissions from hydrocarbon mixtures accounts for the higher evaporation rate of the more volatile components, resulting in a different composition of the mixture in the vapor phase than in the liquid phase. The methodology presented in this standard assumes that there is sufficient liquid present such that the chemical composition at the liquid surface may be considered to not change as a result of the evaporative loss.

API 2350 Overfill Protection for Storage Tanks in Petroleum Facilities
4th Edition May 2012 (R2017 Pending)
ANSI/API Standard 2350 addresses overfill protection for petroleum storage tanks. It recognized that prevention provides the most basic level of protection, thus while using both terms “protection” and “prevention”, the document emphasizes prevention. The standard’s scope covers minimum overfill (and damage) prevention practices for aboveground storage tanks in petroleum facilities, including refineries, marketing terminals, bulk plants, and pipeline terminals that receive flammable and combustible liquids.
Use of this standard is intended for storage tanks associated with marketing, refining, pipeline and terminals containing Class I or Class II petroleum liquids. Use is recommended for Class III petroleum liquids.This standard does not apply to underground storage tanks; aboveground tanks of 1320 US gallons (5000 liters) or less; aboveground tanks which comply with PEI 600; pressure vessels; tanks containing non-petroleum liquids; tanks storing LPG and LNG; tanks at service stations; tanks filled exclusively from wheeled vehicles (i.e. tank trucks or railroad tank cars); and tanks covered by OSHA 29 CFR 1910.119 and EPA 40 CFR 68 or similar regulations.
This standard recommends applications of PEI Recommended Practice 600 Recommended Practices for Overfill Prevention for Shop-Fabricated Aboveground Tanks for overfill protection where applicable for aboveground tanks falling outside the scope of this document.
The purpose of this standard is to assist owner/operators and operating personnel in the prevention of tank overfills by implamentation of a comprehensive overfill prevention process (OPP). The goal is to receive product into the intended storage tank without overfill or loss of containment.
This standard is one of minimum requirements. Alternate approaches or variations on the principles of this standard that provide equivalent or more robust overfill prevention are acceptable. Alternate approaches may be needed when the tank system varies from the typical configurations described in this standard. The rationale for the implementation of each overfill prevention process (OPP) should be documented and retained by the owner and operator.

API STD 2540 Standard Petroleum Measurement Tables
These Petroleum Measurement Tables are for use in the calculation of quantities of crude petroleum and petroleum products at required conditions in any of three widely used systems of measurement. Tables are provided over normal operating ranges for the reduction of gravity and volume to standard states, for calculation of weight-volume relationships, and interconversion of a wide variety of commercially useful units. The tables, issued in three volumes, cover United States, British, and Metric systems of measurement
Note 1- These tables supersede ASTM d 206, Abridged Volume Correction Tables, and ASTM D 1090. Tentative Factors and Tables for Volume Correction and Specific Gravity Conversion of Liquefied Petroleum Gases. Because of the broader range of values covered, and the larger number of individual tables provided, these tables replace the National Bureau of Standards Circular C-410, and the Supplement thereto ( Abridged Volume Correction Table for Petroleum Oils), which were withdrawn form circulation by the NBS effective January 1, 1954.

API TR 2569 Evaporative Loss from Closed-Vent Internal Floating-Roof Storage Tanks
Addresses evaporative loss from internal floating-roof tanks (IFRTs) with closed vents. When the vents in the fixed roof of an IFRT are closed, rather than open, estimation of emissions is shown to be highly complex. This subject is not covered in other API standards such as Ch. 19.1, which specifically excludes fixed-roof tanks that have an internal floating roof, and Ch. 19.2, which specifically excludes closed internal floating-roof tanks (that is, tanks vented only through a pressure-vacuum relief vent, blanketed with an inert gas, vented to a vapor processing unit, or otherwise restricted from being freely vented).
