IP codes IP65 touchscreen display IP65 LED lamp. The IP code or ingress protection code indicates how well a device is protected against water and dust. It is defined by the International Electrotechnical Commission (IEC) under the international standard IEC 60529 [1] which classifies and provides a guideline to the degree of protection provided by mechanical casings and electrical enclosures ...
WAG – water alternating gas (describes an injection well which alternates between water and gas injection [citation needed]) WALKS – walkaway seismic profile; WAS – well access system; WATAN – water analysis; WAV3 – amplitude (in seismics) WAV4 – two-way travel time (in seismics) WAV5 – compensate amplitudes; WAVF – waveform log
A garment described as waterproof will have a water-repellent coating, with the seams also taped to prevent water ingress there. Better waterproof garments have a membrane lining designed to keep water out but allow trapped moisture to escape ("breathability")—a totally waterproof garment would retain body sweat and become clammy. Waterproof ...
During the 1990s, the Texas Legislature moved to make natural-resource protection more efficient by consolidating programs. In 1991, it combined the Texas Water Commission and the Texas Air Control Board to create the first version of the TCEQ, known as the Texas Natural Resource Conservation Commission until fall 1993.

In Texas, there are 98 of these districts, covering nearly 70% of the state, according to the Texas Water Development Board. The Upper Trinity Groundwater Conservation District has the following ...
In the late 1980s NASA began to consider replacing its previous neutral-buoyancy training facility, the Weightless Environment Training Facility (WETF). The WETF, located at Johnson Space Center, had been successfully used to train astronauts for numerous missions, but its pool was too small to hold useful mock-ups of space station components of the sorts intended for the mooted Space Station ...
The European Standard EN 62262 — the equivalent of international standard IEC 62262 (2002) — relates to IK (impact protection) ratings. [1] This is an international numeric classification for the degrees of protection provided by enclosures for electrical equipment against external mechanical impacts.
Dye penetrant inspection (DP), also called liquid penetrate inspection (LPI) or penetrant testing (PT), is a widely applied and low-cost inspection method used to check surface-breaking defects in all non-porous materials (metals, plastics, or ceramics).
