It sounds like you already know the answer you want, but the answer depends upon which certification agency you want the answer for. For most "sport" agencies, the maximum operating partial pressure is 1.40 with an emergency contingency pressure of 1.60. However ANDI, sets the maximum operation pressure at 1.45 and some technical agencies set it at 1.3 once you go deeper than 100 feet or 30 meters.
You know, the factors of partial pressure
total pressure = sum of all partial pressures.
Dalton's law of partial pressures) states that the total pressure exerted by the mixture of non-reactive gases is equal to the sum of the partial pressures of individual gases.
The pressure of each gas in a mixture is called the partial pressure of that gas.
The concept that the total pressure of a mixture of gases is the sum of their partial pressures was developed by John Dalton in the early 19th century. This idea forms the basis of Dalton's Law of Partial Pressures.
The total pressure of a gas mixture is the sum of the individual pressures.
Dalton's Law of partial pressures states that the total pressure of a gas mixture is equal to the sum of the partial pressures of each individual gas in the mixture. This law is based on the idea that each gas in a mixture behaves independently of the others. Mathematically, it can be expressed as P total = P1 + P2 + ... + Pn, where P total is the total pressure and P1, P2, ...Pn are the partial pressures of each gas.
The law of partial pressures states that in a mixture of gases, the total pressure is equal to the sum of the partial pressures of the individual gases. This law is described by the equation: P_total = Pā + Pā + ... + Pn, where P_total is the total pressure and Pā, Pā, ... Pn are the partial pressures of the individual gases.
The partial pressure is the pressure exerted by just one gas in the mixture.
The total pressure of a gas mixture is the sum of the individual pressures.
Yes. That is True. Dalton's Law is: that pressure exerted by a mixture of gases is the sum of the pressures exerted independently by each gas in the mixture. Reference: Human Anatomy and Physiology Marieb and Hoehn
