General Purpose Skid-Mounted Packaged Equipment Specification
This Practice provides minimum requirements for mechanical design and manufacturing of skid-mounted packaged equipment. Skid-mounted units are self-contained, consisting of equipment, their auxiliary systems, interconnecting piping, electrical and instrument components, controls, and support structures, which are normally fabricated and skid-mounted in one or more sections. Skid-mounted packaged equipment may include a broad range of designs for process and utility applications, such as refrigeration units, vacuum pumps, chemical injection systems, and filter packages. This Practice is intended to address basic requirements that are common to most skid-mounted packages. Comment Purchaser shall ensure that specifications are invoked and provided for specific applications, which are equal to or exceed the scope of this Practice. Purchaser may also provide data sheets, P&IDs, process data, and any other supplemental specifications to define requirements for specific packaged equipment.

Specification for Small Pressure Vessels and Heat Exchangers with Limited Design Conditions
This Practice provides general requirements for the design, materials, fabrication, examination, inspection, testing, certification, and pressure relief of three classes of small pressure vessels and heat exchangers as defined by size and Maximum Allowable Working Pressure (MAWP) in Table 1a or 1b of this Practice. This Practice is applicable to a. The standard, pre-designed pressure vessels and heat exchangers supplied as part of pre-engineered package units (e.g., refrigeration and air-compressor systems) b. “Off-the-shelf” vessels and exchangers c. Vessels (e.g., filters) or exchangers built from the manufacturer’s standard parts For purposes of this Practice, the term “vessel” includes heat exchangers. This Practice is not intended for the following a. Vessel in “Lethal Service” as defined in Section VIII, Division 1 of the ASME Boiler and Pressure Vessel Code (Code) b. Vessels for which design wall thickness is governed by loadings from wind pressure or earthquake forces

Ceramic Fiber Refractory Installation Qualification, Inspection, and Testing
This Practice provides requirements for quality control and quality assurance for the installation of ceramic fiber refractory. Inspection methods include documentation review, in-progress installation inspection, and final inspection of the completed lining.
Reaffirmation

Tank Selection Guide
This Practice provides guidelines for aboveground storage of liquid products in tanks at design pressures from atmospheric to 15 psig (103 kPa). This Practice also provides guidance for avoiding recurring problems and outlines preferred practices where appropriate. Although this Practice is intended primarily for carbon steel tanks, most of the guidelines are applicable regardless of the material of construction.
Technical Revision

Design and Fabrication of Flooded-Cell Lead-Acid Batteries
This Practice provides the requirements for design and fabrication of vented, flooded-cell lead-acid batteries and accessories. It further describes the design, inspection, testing, shipment, and documentation for these type batteries for application in electrical stations or uninterruptible power supplies (UPS) in indoor, nonclassified areas.
