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 ...
The International Organization for Standardization (ISO) issued a standard for water-resistant watches which also prohibits the term waterproof to be used with watches, which many countries have adopted. This standard was introduced in 1990 as the ISO 2281:1990 and only designed for watches intended for ordinary daily use and are resistant to ...
The VPAM scale as of 2009 runs from 1 to 14, with 1-5 being soft armor, and 6-14 being hard armor. [1] Tested armor must withstand three hits, spaced 120 mm (4.7 inches) apart, of the designated test threat with no more than 25 mm (0.98 inches) of back-face deformation in order to pass.
Water resistance is measured by the amount of water, in mm, which can be suspended above the fabric before water seeps through. [ citation needed ] Breathability or moisture vapor transmission rate is measured by the rate at which water vapor passes through, in grams of water vapour per square meter of fabric per 24-hour period (g/m 2 /d), [ 2 ...
Typical maximum with current technologies are in 15,000 range. High-performance fabrics may get A1 test scores in 10,000 to 15,000 g m −2 d −1 range and usually shows that a fabric has a fairly quick release of moisture, but may not be the best over longer periods of use.
ISO 18265: "Metallic materials — Conversion of hardness values" (2013) ASTM E140-12B(2019)e1: "Standard Hardness Conversion Tables for Metals Relationship Among Brinell Hardness, Vickers Hardness, Rockwell Hardness, Superficial Hardness, Knoop Hardness, Scleroscope Hardness, and Leeb Hardness" (2019)
In construction, a building or structure is waterproofed with the use of membranes and coatings to protect contents and structural integrity. The waterproofing of the building envelope in construction specifications is listed under 07 - Thermal and Moisture Protection within MasterFormat 2004, by the Construction Specifications Institute, and includes roofing and waterproofing materials.
Machinist's Mate (or MM) is a rating in the United States Navy's engineering community. It is non-capitalised as machinist's mate when discussing the generic rating rather than as a proper noun when discussing a specific enlisted seaman (Machinist's Mate Jane Doe, MM John Doe) carrying that rating.
