§1692. Power Loads.

(a) Identification of Cased Power Loads. Cased power loads shall be coded to identify power load levels by case color and power load color as specified in Table 1.

(b) Identification of Caseless Power Loads. Caseless power loads shall be coded to identify power load levels by power load color as specified in Table 1 and by configuration.

(c) Power Load Use Limitation. No power load (cased or caseless) shall be used if it will properly chamber in any existing commercially available tool and will cause a fastener to have a test velocity in excess of the maximum test velocities specified for the tool.

(d) Identification of Power Load Packages. Power load packages shall provide a visual number-color indication of the power level of the power load as specified in Table 1.
