Scope:

This SAE Recommended Practice is intended as a guide toward standard practice and is subject to change to keep pace with experience and technical advances. This document establishes performance requirements, material requirements, design requirements, and design guidelines for sealed beam headlamps.

Rationale:

Proposed SAE J2595 [Modified Sections of J1383]:

a. SAE J2595 has been created as a result of rewriting SAE J1383. The intent is to remove all sealed beam information from SAE J1383 and place it in this new SAE J2595 document.

b. Removed all text, figures and tables from J1383 that apply to sealed beam. Ref. Text Sections - 3.3, 3.20, 4.4, 5.0, 5.1.2, 5.6, 5.7.5, 5.8, 5.8.1, 5.8.2, 5.8.3, 5.8.4, 5.8.5, 5.12.3, 5.13, 5.13.1, 5.13.2, 5.13.3, 5.14, 5.14.1, 5.14.2, 5.14.3, 6.1.2, 6.7,6.7.1, 6.7.2, 6.9, 6.14, 6.15, 6.22.3.4, 6.22.3.5, 6.22.3.6, 6.22.3.7, 6.22.8, 6.22.9, 6.22.10, 7.3, 7.4 items c and d, 7.6, 8.0 through 8.4.2.10 [entire section of "Replaceable Bulb Filament Dimensions and Location Tests"].

Ref. Figures - 9, 10, 19, and 33 through 82B. Ref. Tables - 1 and 2.

c. Revised numerical order of definitions, identification code designation, tests, performance requirements and guidelines.

d. Figures 13 through 27 were redrawn for clarity.

e. Removed Tables 4, 6, 7 and 8 and combined them into one new Table 2.

f. Removed Table 9 [test classification]. Was redundant and not used.

g. Removed the 56 x 75mm "J" lamp [Figures 29 and 30] and associated criteria. Not used.

h. Corrected the 55 x 135 lamp drawings [Figures 31 and 32]. The current drawings depicted do not meet the specifications of the original concept.

i. Changed the identification whereas the 55 x 135 lamps were referred to as "LK" and "UK". These lamps were not adopted by NHTSA as sealed beams and therefore were not officially assigned lamp codes.

j. Maintained the sections pertaining to VHAD in effort to meet the aiming needs of the 55 x 135 lamp. Ref. Sections 3.19, 5.10, 6.11.3, 6.11.4 and 6.22.6 through 6.22.7.3.3.
