At ambient temperature and at atmospheric pressure nitrogen is introduced into two bottles of equal volume one of which contains the test portion while the other is empty. The connected bottles are immersed in the refrigerant bath of liquid nitrogen. Since some nitrogen is adsorbed by the sample a differential pressure occurs between the two bottles and is measured by means of a differential…
Specifies requirements for fittings for threaded connections, used mainly for industrial purposes. Table 1 contains diagrams of types of fittings and their symbols. Tabulates the fitting dimensions (tables 2, 5, 9 to 12) with nominal sizes from DN 6 up to and including DN 100 (thread designation 1/8 to 4). Table 6 contains sockets (DN 6 to DN 150), reducing fittings are included in the tables 3,…
Road vehicles — Screened and waterproof spark-plug and its connection — Type 2
Specifies the essential dimensional characteristics of a spark-plug type used with spark ignition engines. Tabulates major, pitch, and minor diameters for plug thread and connector thread. A figure illustrates shapes and reference quantities of concern. This third edition cancels and replaces the second edition (1979).
Road vehicles — Screened and waterproof spark-plug and its connection — Type 3
Specifies the essential dimensional characteristics of a spark-plug type used with spark ignition engines. Tabulates major, pitch, and minor diameters for plug thread and connector thread. A figure illustrates shapes and reference quantities of concern. This third edition cancels and replaces the second edition (1979).
Apply only to the type of backflow preventer identified as
dual-check-valve type for use on residential supply service or
individual outlets. They also cover vacuum breakers for use on
laboratory faucets in nominal pipe size of 3/8 only, although
inlet or outlet connections, or both, may be different when so
required for special installations
