13、 that some scheme should be devised to identify piping. In 1908, an article on“Identification of Power House Piping by Colors” was read at a meeting of The American Societyof Mechanical Engineers. In 1909, an article called “Standard Colors for Power Station Piping”was read at the meeting of the Ass
14、ociation of Edison Illuminating Companies.In 1920, the National Safety News pointed out the need for a color scheme for pipelines, andthe following year several papers were published and reports made to various committees,notably the Prime Movers Committee of the National Electric Light Association,
15、 The AmericanSociety of Mechanical Engineers, and the U.S. Navy Department.In the meantime, many large companies compiled their own scheme with no thought tostandardization of pipe colors, even in their own plants. When personnel were shifted, accidentscould and did happen.The organization of the Se
16、ctional Committee on the Identification of Piping Systems, under theprocedure of the American Standards Association (now called the American National StandardsInstitute), took place on June 14, 1922, resulting in the 1928 publication.On August 23, 1950, the committee was reorganized to investigate t
17、he possibility of a revisionto the Standard. It was felt that a revision was necessary because of the tremendous number ofdifferent materials being carried in pipes. After many meetings and much discussion, a revisionof American Standard, Scheme for Identification of Piping Systems, was approved by
18、the sectionalcommittee and sponsors. It was then presented to the American Standards Association (nowcalled the American National Standards Institute) for approval and designation as an AmericanStandard. This was granted on January 27, 1956.In the late 1960s, the committee began discussions on the p
19、ossibility of revising the 1956Standard. These discussions continued for a number of years, eventually resulting in approvalby the American National Standards Institute (ANSI), and designation as an American NationalStandard was obtained on June 13, 1975.In accordance with the policy of ANSI, the co
20、mmittee began a review of the 1975 Standardfor a possible revision in the late 1970s, which resulted in approval by ANSI and designation asan American National Standard on November 16, 1981.The 1996 edition of A13.1 was approved by ANSI and designated an American NationalStandard on August 13, 1996.
21、The 2007 edition of A13.1, which was approved by the A13 Committee and ASME, was approvedby ANSI on February 12, 2007.This edition incorporates the GHS pictograms and adds a definition for oxidizing.ASME A13.1-2015 was approved by ANSI on October 30, 2015.ivASME A13.1 COMMITTEEScheme for the Identif

Identification may be accomplishedby stenciling, the use of tape, or markers. In any situa-tion, the number and location of identification markersshall be based on
24、the particular piping system.(15)(15)ASME A13.1-2015The applicable GHS1pictogram as illustrated in Fig. 1may be included as part of the legend.Where piping is connected to containers that arelabeled in accordance with GHS requirements, a corres-ponding label on the piping may be provided. The cor-re
25、sponding label should contain at least the productname or identifier, the pictogram, the signal word, andthe physical, health, and environmental hazardstatement(s).3.2 ColorColor should be used to identify the characteristichazards of the contents. Color should be displayed on,or contiguous to, the
26、piping by any physical means, butits use shall be in combination with legend. Color maybe used in continuous, total length coverage or in inter-mittent displays. Colors preceded by the word “Safety”shall meet the requirements of ANSI Z535.1 (see Table 2).3.3 VisibilityAttention shall be given to vis

Where pipelines are located above or1Globally Harmonized System of Classification and Labelling ofChemicals (GHS), latest edition, published by the United Nations.2below the normal line of vision, the lettering shall beplaced below or above the horizontal cent

(13 mm) and larger, is recommended. SeeTable 3 for specific size recommendations. For identifica-tion of materials in p
29、iping with an outside cover diame-ter less than34in. (19 mm), and for valve and fittingidentification, the use of a permanently legible tag isrecommended.3.5 Unusual or Extreme SituationsPiping layouts that are in a limited area of inaccessibil-ity or of extreme complexity may require substitute tec
30、h-niques to achieve positive identification. Use ofsubstitute techniques shall be limited to such segmentsand shall not deviate from the concept of identificationdescribed in paras. 3.1, 3.2, and 3.3.2Sans serif gothic bold lettering provides high readability.(15)(15)ASME A13.1-2015Fig. 1 GHS Pictog
