Definition Definition of approved item name (AIN): "HEAD,SAFETY,PRESSURE RELIEF"

An item of varying shape and size consisting of a metallic body which incloses a nonreusable metallic or nonmetallic disk(s), which is designed and calibrated to burst at a given pressure. It may be used independently, or in conjunction with relief valves to relieve overpressure, and to protect relief valve(s) from corrosive conditions. Excludes valve, safety relief and plug, fusible. for items furnished with a disk, see head and disk, safety, pressure relier.

  Identification Codes

HMIC: Hazardous Material Indicator Code. A one position code that identifies a hazardous item.

PMIC: Precious Metal Indicator Code. A one position code which identifies items that have precious metals as part of their content. precious metals are those metals generally considered to be uncommon, highly valuable, and relatively superior in certain properties such as resistance to corrosion and electrical conductivity.

ESD: Electrostatic Discharge. Indicates if an item is susceptible to electrostatic discharge or electromagnetic interference damage. electrostatic discharge damage occurs when an accumulation of static electricity generated by the relative motion or separation of materials is released to another item by direct contact. electromagnetic interference damage occurs when an item comes into proximity with an electrostatic or magnetic field.

ENAC: Enviromental Attribute Code. Identifies items with environmentally preferred characteristics.

CRITL: Criticality Indicator Code. Indicates an item is technically critical by tolerance, fit, application, nuclear hardness properties, or other characteristics.
