Updated Guidelines, October 2018

ASHRAE Guideline 1.3-2018

Directriz ASHRAE 1.3-2018, Formación en O&M de Edificios Asociada al Proceso Commissioning de Instalaciones de Climatización y Refrigeración, is now one of six ASHRAE guidelines translated into Spanish.

The guideline, which focuses on the building operations and maintenance training for the HVAC&R commissioning process, offers guidance on training O&M staff in all aspects related to commissioning, as outlined in ASHRAE Guideline 0.

Because well-trained building personnel can positively influence performance outcomes at every phase of a Cx project, Guideline 1.3 covers implementation strategies and methodologies for training O&M staff and owners, formats for developing training plans, tips on how to conduct training programs, and documenting training results.

This guideline is part of a larger collection of commissioning process documents from ASHRAE. For a full list of Spanish-translated ASHRAE guidelines and standards, visit.

ASHRAE Guideline 11-2018

ASHRAE Guideline 11-2018, Field Testing of HVAC Controls Components, provides procedures for field testing and adjusting of control components used in building heating, ventilating, and air-conditioning (HVAC) systems.

This edition addresses newer direct digital control (DDC) technology while still allowing the reader to understand the nuances of the older pneumatic systems still in use. Redundant language has been removed. The guideline was last updated in 2009.

ASHRAE Guideline 38-2018

ASHRAE Guideline 38-2018, Guideline for Using Metal Pressure Vessels to Test Materials Used in Refrigeration Systems, is a new publication that establishes a test procedure using metal pressure vessels for the evaluation of materials used in refrigeration systems.

The use of metal vessels will allow for the testing of a variety of materials, regulating the pressure of the test, utilization of a realistic sample size to oil/refrigerant ratio and other analytical tests, such as extraction, according to the guideline’s purpose.

The guideline’s scope is to describe the preparation of metal pressure vessels, the procedure for charging them with refrigerant and with the materials to be tested and a  procedure for heating the metal vessel and regulating the pressure is described.

Post-test evaluations can be done quantitatively and/or qualitatively by observing the metal vessel contents to yield information for determining the compatibility, suitability or chemical stability of materials in the refrigerant environment. The technique described can be used for evaluating many different types of materials.
