How do I demonstrate compliance if I manufacture multi-component kits?

(a) If you manufacture multi-component kits as defined in § 59.503, then the Kit PWR must not exceed the Total Reactivity Limit. (b) You must calculate the Kit PWR and the Total Reactivity Limit as follows: (1) KIT PWR = (PWR (1) × W 1 ) + (PWR (2) × W 2 ) + . ... + (PWR (n) × W n ) (2) Total Reactivity Limit = (RL 1 × W 1 ) + (RL 2 × W 2 ) + ... + (RL n × W n ). (3) Kit PWR ≤Total Reactivity Limit. Where: W = the weight of the product contents (excluding container). RL = the PWR Limit specified in Table 1 of this subpart. Subscript 1 denotes the first component product in the kit. Subscript 2 denotes the second component product in the kit. Subscript n denotes any additional component product.
