Refrigeration compressors are pivotal components in cooling systems, responsible for the circulation and compression of refrigerant gases. To ensure their optimal performance, various standards have been established worldwide. This article provides an insightful comparison of four prominent standards: EN12900, ASHRAE, CECOMAF, and Standard TE. Each standard delineates specific parameters and conditions for evaluating the efficiency and effectiveness of refrigeration compressors.

EN12900 (European Standard):

EN12900 stands as a cornerstone European standard, meticulously detailing the requisites and assessment protocols for hermetic and semi-hermetic refrigerant compressors. Its focus lies in ensuring compliance with rigorous performance benchmarks within the European market.

Key Parameters:

Rating Conditions: EN12900 prescribes precise conditions for the examination of compressors, encompassing refrigerant specifications, condensing temperature, evaporating temperature, and oil temperature. This specificity aids in creating a standardized testing environment.

Test Points: It establishes a set of standardized operational points, encompassing low, medium, and high load conditions. This allows for a comprehensive evaluation of the compressor’s performance across various scenarios.

Performance Criteria: The standard mandates requirements for capacity, efficiency, and a spectrum of other performance metrics at the defined test points. This ensures a thorough assessment of the compressor’s capabilities.


Primarily employed within the European context, EN12900 serves as a vital tool for evaluating and certifying the performance of refrigeration compressors within the European market.

ASHRAE (American Society of Heating, Refrigerating, and Air-Conditioning Engineers):

ASHRAE, a preeminent American professional organization, is dedicated to the advancement of heating, ventilation, air conditioning, and refrigeration systems. Their Standard 23 is pivotal in establishing rating conditions for refrigeration and air conditioning equipment, including compressors.

Key Parameters:

Rating Conditions: ASHRAE Standard 23 provides a comprehensive framework for rating conditions, tailored to the specific demands of different applications. This adaptability ensures a relevant evaluation of compressor performance.

Performance Data: Compressor manufacturers often furnish performance data based on ASHRAE rating conditions. This data aids end-users in making informed decisions regarding the selection of compressors.


Widely adopted in North America and globally, ASHRAE standards play a central role in evaluating and specifying HVAC&R equipment, including refrigeration compressors.

CECOMAF (Comité Européen de Construction d’Appareils à Moteur et à Fluides):

CECOMAF, a prominent European organization, is dedicated to motor-driven appliances and fluid equipment, notably including refrigeration systems. Their standards provide specific conditions for testing compressors, mirroring EN12900 but with a unique European focus.

Key Parameters:

Rating Conditions: CECOMAF prescribes its own set of rating conditions, aligning closely with EN12900. These conditions are tailored to meet the specific requirements of the European market.

Performance Data: Compressor manufacturers often provide performance data based on CECOMAF rating conditions, allowing for a precise assessment of compressor capabilities.


CECOMAF standards are predominantly utilized within Europe for the comprehensive evaluation of refrigeration compressors, ensuring compliance with European market demands.

Standard TE (Thermally Equivalent Operating Conditions):

Standard TE is a term referring to a set of conditions established for the equitable comparison of compressors from different manufacturers. While not a specific standard like EN12900 or ASHRAE, it provides a framework for performance evaluation.

Key Parameters:

Rating Conditions: Standard TE conditions may vary depending on the specific application, designed to represent a spectrum of operating conditions pertinent to a particular industry or market.

Performance Comparison: Standard TE allows for a fair comparison of compressors from different manufacturers, empowering end-users to make well-informed decisions regarding compressor selection.


Standard TE conditions find applicability in various regions and industries, providing a standardized platform for the assessment and comparison of refrigeration compressors.

Each standard or condition, whether EN12900, ASHRAE, CECOMAF, or Standard TE, plays a pivotal role in assessing and certifying refrigeration compressors. Manufacturers frequently provide performance data aligned with these standards, facilitating informed decision-making for end-users. Always consult the specific standard or condition for comprehensive details on rating conditions and testing protocols.
