5、g the Color Guideline 1 Section 5. Assignment Criteria 2 TABLES Table 1. Refrigerant Container Color definitions; basic considerations for developing the color guideline; and assignment criteria. 1.1.1 Intent. This guideline is intended for the guidance of the industry, including manufacturers, engi
6、neers, installers, contractors and users. 1.1.2 Review and Amendment. This guideline is subject to review and amendment as technology advances. Section 2. Scope 2.1 Scope. This guideline provides a means by which colors can be assigned to refrigerant containers for Refrigerants currently in use or n
7、ewly developed Refrigerants, provided the Refrigerant is used in significant quantities as defined in this guideline. Colors should not be relied upon exclusively to determine the type of Refrigerant in the container. This guideline also recommends a container color for Refrigerants that are not pro
8、duced in sufficient quantities to qualify for their own individual color. 2.2 Exclusions. This guideline does not cover container colors for recovered and recycled Refrigerants, which are covered in AHRI Guideline K. Section 3. Definitions All terms in this document will follow the standard industry
9、 definitions in the ASHRAE Terminology website (https:/www.ashrae.org/resources-publications/free-resources/ashrae-terminology) unless otherwise defined in this section. 3.1 Refrigerants. Refrigerants for purposes of this guideline include single component refrigerants, zeotropes and azeotropes. 3.1
10、.1 Flammable Refrigerants. Those Refrigerants that receive a flammability rating of 2 or 3 in ANSI/ASHRAE Standard 34, Designation and Safety Classifications of Refrigerants with Addenda. 3.1.2 High Pressure Refrigerants. Those Refrigerants meeting the definition of a compressed gas. The gas should
11、have a minimum cylinder service pressure exceeding 3447 kPa (gage). 3.1.3 Liquid Refrigerants. Those Refrigerants with a normal boiling point greater than 20C. These products normally are packaged in drums. 3.1.4 Low Pressure Refrigerants. Those Refrigerants meeting the definition of a “compressed g
12、as.” The gas should have a minimum cylinder service pressure not exceeding 3447 kPa (gage). 3.2 “Should.“ “Should“ is used to indicate provisions which are not mandatory but which are desirable as good practice. Section 4. Basic Considerations for Developing the Color Guideline 4.1 The color guideli
13、ne is not a substitute for reading cylinder labels and markings. 4.2 Refrigerants are grouped in four classes in order to create more color opportunities within readily identifiable container styles and to clearly differentiate Flammable Refrigerants. Class I: Liquid Refrigerants Class II: Low Press
14、ure Refrigerants Class III: High Pressure Refrigerants AHRI GUIDELINE N-2014 2 Class IV: Flammable Refrigerants 4.3 The color guideline should allow for the addition of new Refrigerants in each of the above classes. 4.4 Color codes only need to be differentiated within a class. Consideration should
15、be given to the application before assigning colors to the Refrigerant. 4.5 Colors should be distinguishable from each other. 4.6 The color guideline should be standard industry-wide. 4.7 Color option should minimize container painting costs. 4.8 A red band on the shoulder or top of the container sh
16、ould designate flammable compounds, or mixtures that could become flammable in the event of a leak. 4.9 Refrigerants that are not produced in sufficient quantities to qualify for their own individual color should be painted light green gray (PMS 413). Section 5. Assignment Criteria 5.1 The Refrigera
17、nt manufacturer should notify AHRI of its intent to use a color not previously assigned for that Refrigerant class to a new Refrigerant they plan to commercialize within six months. The manufacturer requesting a specific PMS color assignment for that new Refrigerant should also provide a correspondi
18、ng RAL K5 classic number. If the manufacturer does request a specific PMS color and or RAL K5 classic number, AHRI will assign them. 5.2 In order to retain assignment of the color, the manufacturer should furnish confirmation to AHRI that: 5.2.1 A Refrigerant number has been published in ANSI/ASHRAE
19、 Standard 34. 5.2.2 There have been commercial sales, and there will be continued offering of the Refrigerant within one year of assignment. 5.2.3 There have been commercial sales of at least 45,350 kg per year for Class I and Class II Refrigerants or 900 kg per year for Class III Refrigerants withi
20、n two years of assignment. Commercial sales of Class IV Refrigerants should be consistent with commercial volumes which would be required if it were a non-flammable Refrigerant. 5.3 If the manufacturer who originally requested and obtained the use of a color falls below the levels established in Sec
