Final answer:
Solvent cements should be applied in an ambient temperature range of 40°F to 110°F to ensure proper bonding and drying.
Step-by-step explanation:
When applying solvent cements, ambient temperatures should generally be in the range that allows the chemical to work effectively without prematurely evaporating or not setting properly. For many products, the ideal application temperature range is typically above freezing and below a temperature where the solvent would evaporate too quickly, which is often around room temperature. Considering the context provided and common practices in construction and engineering fields, it is recommended to apply solvent cements in an ambient temperature range of 40°F to 110°F (4.4°C to 43°C). This range ensures that the cement has enough time to adequately bond materials before drying and that it is not too viscous to apply evenly.
