You can use it when discussing the duration of something, but it would be clearer to choose either "long term" or "lifetime" instead.
Example: "The product is designed for a long term use, ensuring it lasts throughout its lifetime."
Alternatives: "an extended duration" or "a prolonged lifespan."
She said the development of under-sea drones and other technologies on the horizon might make a long-term lifetime spending commitment of between £100 billion and £160 billion unwise.
The current analysis has a long-term (lifetime) time horizon and is based on patients with high baseline cardiovascular risk (≥20% or ≥30% Framingham), which is in line with new European labeling recommendations.
Our study supplements the trial findings by providing a measure of the benefits of a single round of screening but considered from the standpoint of long term (lifetime) follow-up.
[Medication-assisted treatment, or MAT, anticipates a long-term — often lifetime — regimen of medication, supplemented with therapy, counseling, and/or support groups.
The MPPD input parameters determined to be significant were evaluated further to calculate mass retained in the alveolar region per alveolar surface area, based on two exposure durations: a short-term exposure duration of 24 hr and a long-term occupational lifetime exposure.
To establish an efficient (reduced) chloride ingress model ensuring a good accuracy (with respect to the complete model) with reduced computational effort for long-term lifetime assessment under realistic climate and exposure conditions.
The long-term lifetime context of approximately 15 25 years for offshore wind parks creates an institutional framework for innovation among triple helix parties of industry, university and government as noted by Etzkowitz and Leydesdorff (2000).
Human health standards are the first step in defining acceptable risk for human space flight and take into consideration both short-term (mission) and long-term (lifetime) health risk.
Experiments on both "accelerated" (by applying thermal stress to the devices) and "long-term" lifetime measurements of traditional organic bulk heterojunction solar cell devices have been realized while controlling the environmental conditions.
Long-term lifetime tests have shown, however, that the cathode loaded with 2.63 mg/cm2 Ag catalyst has lifetime longer than 3 years under the practical chlor-alkali electrolysis conditions, while the cathode loaded with 0.56 mg/cm2 Pt catalyst has shown potentiality to have lifetime over 2 years.
Finally, by convention, cost-effectiveness analysis considers long-term (lifetime) horizons [ 37].
