We propose new methods to determine the P parity of the K mesons experimentally, based on the measurement of polarization observables in K-meson production in polarized proton-proton collisions. The first method is based on the measurement of the sign of the spin correlation coefficient with transversally polarized protons. The second one is based on the measurement of the polarization transfer coefficient from the initial proton to the produced hyperon. [S0556-2821(99)01905-0].
