Impact Statement: A review of all Listing Reports is necessary to determine which products comply with new/revised requirements and which products will require re-evaluation. NOTE: Effective immediately, this revised standard will be exclusively used for evaluation of new products unless the Applicant requests in writing that current requirements be used along with their understanding that their listings will be withdrawn on Effective Date noted above, unless the product is found to comply with new/revised requirements.

Overview of Changes: The changes with respect to the previous edition include the update and clarification to the Flammability Test and to revise the user replaceable fuse marking. Specific details of new/revised requirements are found in table below.

Additions to existing requirements are underlined and deletions are shown lined out below

The test flame is to be obtained by means of a Bunsen or Tirrill burner having a nominal bore of 3/8 inch (9.5 mm) and a length of 4 inches (102 mm) above the primary air inlets. A gas supply of 1000 BTU per cubic foot (37 MJ/m3 ) at normal pressure is to be used and the flame adjusted so that, while the burner is vertical, the overall height of flame is 3/4 inch (19.1 mm). The flame shall be yellow in appearance with no appreciable inner blue cone.

A laboratory type burner having a tube with a length of 100 ±10 mm (3.94 ±0.39 inch) and an inside diameter of 9.5 ±0.3 mm (0.374 ±0.012 inch) is to be used. The barrel is not to be equipped with an end attachment, such as a stabilizer. The burner shall be in compliance with Specification for a Laboratory Burner Used for Small-Scale Burning Tests on Plastic Materials, ASTM D5025. Adjust the burner to produce a blue flame 20 ±1 mm high (3/4 inch nominal). The flame is obtained by adjusting the gas supply and air ports of the burner until a 20 ±1 mm (3/4 inch nominal) yellow-tipped blue flame is produced. Increase the air supply until the yellow tip just disappears. Measure the height of the flame again and readjust it if necessary. The test flame shall be calibrated in accordance with Standard Practice for Calibration of 20 mm and 125 mm Test Flames for Small-Scale Burning Tests on Plastic Materials, ASTM D5207, at least once a month and when the gas supply is changed, test equipment is replaced, or when data is questioned.
