VSP 2018 Construction Guidelines

Seam: An open juncture greater than 0.8 millimeters (1/32 inch) but less than
3 millimeters (1/8 inch).

Smooth:
• A FOOD-CONTACT SURFACE having a surface free of pits and
inclusions with a cleanability equal to or exceeding that of (100-grit)
number 3 stainless steel.
• A NONFOOD-CONTACT SURFACE of EQUIPMENT having a surface
equal to that of commercial grade hot-rolled steel free of visible scale.
• Deck, BULKHEAD, or DECKHEAD that has an even or level surface
with no roughness or projections to make it difficult to clean.

Spa pool: A POTABLE WATER or saltwater-supplied pool with temperatures and
turbulence comparable to a WHIRLPOOL SPA.
• Depth of more than 1 meter (3 feet) and
• Tub volume of more than 6 tons of water.

Spill-resistant vacuum breaker (SVB): A specific modification to a PRESSURE
VACUUM BREAKER ASSEMBLY to minimize water spillage.

Spray pad: Play and water contact area designed to have no standing water.

Suction fitting: A fitting in a RECREATIONAL WATER FACILITY under direct
suction through which water is drawn by a pump.

Swimming pool: A RECREATIONAL WATER FACILITY greater than 1 meter in
depth. This does not include SPA POOLS that meet this depth.

Technical water: Water that has not been chlorinated or pH controlled on board the
vessel and that originates from a bunkering or condensate collection process, or
seawater processed through the evaporators or reverse osmosis plant and is intended
for storage and use in the technical water system.

Temperature-measuring device (TMD): A thermometer, thermocouple,
thermistor, or other device that indicates the temperature of FOOD, air, or water and
is numerically scaled in Celsius and/or Fahrenheit.

Turnover: The circulation, through the recirculation system, of a quantity of water
equal to the pool volume.

Unblockable drain/suction fitting: A drain or SUCTION FITTING in a
RECREATIONAL WATER FACILITY that cannot be completely covered or
blocked by a 457 millimeters x 584 millimeters (18 inches x 23 inches) body-
blocking element and that is rated by the test procedures or by the appropriate
calculation in accordance with ASME A112.19.8M.
