IIAR BULLETIN 114 PDF

Bulletin was developed and published in as a means to establish uniformity among ammonia refrigeration users and practitioners in identifying refrigerant piping. Since its original publication, the industry has widely adopted the recommended practices for pipe marking, which is a code requirement. The revised standard indicates that orange backgrounds, rather than yellow backgrounds, should be used for toxic and corrosive fluids. Bulletin has been updated to reflect this standard and provide better consistency with general industry standards.

Bulletin was developed and published in as a means to establish uniformity among ammonia refrigeration users and practitioners in identifying refrigerant piping. Since its original publication, the industry has widely adopted the recommended practices for pipe marking, which is a code requirement.

The revised standard indicates that orange backgrounds, rather than yellow backgrounds, should be used for toxic and corrosive fluids. Bulletin has been updated to reflect this standard and provide better consistency with general industry standards. Users and practitioners in the ammonia refrigeration industry have used varying color schemes, or no color schemes, to identify ammonia refrigeration piping systems.

In an effort to bring consistency to the industry and aid in training and safety efforts, Bulletin was revised to also include a suggested color scheme for ammonia refrigeration piping. The suggested color scheme outlined in this document is not intended to replace existing color schemes that have been established by facilities.

It is not intended for any other use. All piping mains, headers and branches should be identified as to the physical state of the refrigerant, i. All components of the refrigeration system, e. The identifying designations given to the piping and components that comprise the refrig - eration system, as shown on system drawings, should be consistent with the nomenclature used for pipe and components in these guidelines.

Taujind See full list below. In either case, the directional arrow or arrowhead will be BLACK in color bulleti proportionate in size to the marker. The same system must used across the entire facility. There are two requirements for these alternate schemes: Applying abbreviations of the names commonly given to components or equipment in an ammonia refrigeration system will assist the operator in identifying components bklletin tracing system piping. Component markers will bear the name of the equipment they identify, e.

IIAR Bulletin 114 (Signage)

Bulletin states that all piping mains, headers and branches should be identified as to the physical state of the refrigerant, i. All components of the refrigeration system, e. Pipe markers in accordance with Bulletin , are designed to identify the refrigerant contained within that piping segment i. The changes specified in the Revision of the guidelines are as follows: Ammonia Piping Abbreviations: The revision contains 28 abbreviations versus 17 contained in the Guidelines. See full list below. The color schemes may also be applied to portions of the refrigeration system beyond machinery rooms. Existing schemes for identification are considered acceptable.

Nirr The guideline specifically allows alternative color schemes, such as the one used in the older version of the IIAR standard — or any other color scheme that works well for your facility. Component markers will bear the name of iiiar equipment they identify, e. They include preferred designations for several new types of equipment. Inthough, the standard was revised. The changes specified in the Revision of the guidelines are as follows: If not, now is a great time to fix it! Standardized abbreviations are used, and each section is printed in a specific way.
