(see 4.7.5). Any of the following conditions resulting from vibration are
considered unacceptable:
(a) Damage to parts.
(b) Loosening of parts.
(c) Degradation of operational performance (including leakage)
below specification requirements.
3.5.7 Shock. The valve shall met the shock requirements as specified in

shall be as shown on figure 1 (see 4.7.3.2).
see 3.1), the valve
3.5.9 Burst pressure. Unless otherwise specified
shall withstand a burst pressure of 140 bars (2030
3.5.10 Operating temperature. Unless otherwise specified (see 3.1), the
valves shall operate throughout a temperature range of minus 40 to 135 degrees
Celsius ("C) when used with fluids suitable for the operating temperature.
3.6 Identification marking. Each valve shall be clearly and permanently
identified by steel stamping, electrochemical etch or equivalent means with
the following information and symbol:
(a)
Manufacturer's name, trademark, or logo.
(b)
Specification sheet part number.
(c)
Manufacturer's part number.
(d)
Assembly date (by quarter and year).
3.7 Interchangeability. In no case shall parts be physically interchange-
able or reversible unless such parts are also interchangeable or reversible with
regard to function, performance and strength.
3.8 Drawings. When specified in the contract or purchase order (see 6.2.1),
