Test tender against the contract and statutory tender qualifications; C028–C029, C035; S022–S023, S031. |

| B14 — Change in condition: Partial |
Distinguish changes caused by the goods’ own defects; C057–C058; S038. |

Apply the specific preinspection-payment and inspection exceptions; C030, C034; S029–S030. |
