This limitation appliesto both PVC substrate and to any cap or film material.Compliance with this requirement shall be demonstrated byone of the methods in 6.165. Physical Requirements5.1 Length and WidthThe nominal length and width of thesiding shall

38、 be as agreed upon between the purchaser and theseller. The actual length shall not be less than14 in. (6.4 mm)of the nominal length and the actual width shall be within 6116in. (1.6 mm) of the nominal width when measured in accor-dance with 6.3 and 6.4.5.2 ThicknessExcept for heavily textured sidin

39、g, theserequirements pertain only to measurements of the portions ofthe siding that are exposed after installation of the panel,measured in accordance with the procedure in 6.5. For heavilytextured siding, these requirements apply to the portion of thesiding selected for measurement in accordance wi
