1.5 Tolerances Where only minus tolerances are given, the dimensions are permitted to be exceeded at the option of the manufacturers. All values which do not carry specific tolerances or are not marked maximum or minimum shall have the following tolerances: Linear dimensions shall be±1/16 in (1.6 mm). Pounds Or pound force shall be±2%. Degrees opening shall be±2 degrees. Electrical measurements shall be±2%.
1.6 Tests described in this standard are performed under laboratory condit ions. Measurements shall be taken under neutral air pressure conditions. In actual usage, results vary because of installation, maintenance and environmental conditions.
1.7 Doors used as fire doors or smoke barriers have additional requirements not covered in this standard.
