  2. Hygrometer - Wikipedia

    en.wikipedia.org/wiki/Hygrometer

    The metal-paper coil hygrometer is very useful for giving a dial indication of humidity changes. It appears most often in inexpensive devices, and its accuracy is limited, with variations of 10% or more. In these devices, water vapor is absorbed by a salt-impregnated paper strip attached to a metal coil, causing the coil to change shape.

  3. ANSI/ASME Y14.1 - Wikipedia

    en.wikipedia.org/wiki/ANSI/ASME_Y14.1

    A size chart illustrating the ANSI sizes. In 1992, the American National Standards Institute adopted ANSI/ASME Y14.1 Decimal Inch Drawing Sheet Size and Format, [1] which defined a regular series of paper sizes based upon the de facto standard 8 + 1 ⁄ 2 in × 11 in "letter" size to which it assigned the designation "ANSI A".

  4. ISO 216 - Wikipedia

    en.wikipedia.org/wiki/ISO_216

    The standard defines the "A", "B" and "C" series of paper sizes, which includes the A4, the most commonly available paper size worldwide. Two supplementary standards, ISO 217 and ISO 269, define related paper sizes; the ISO 269 "C" series is commonly listed alongside the A and B sizes.

  5. ISO 217 - Wikipedia

    en.wikipedia.org/wiki/ISO_217

    The sizes of the RA series are also slightly larger than corresponding inch-based US sizes specified in ANSI/ASME Y14.1, e.g. RA4 is roughly equivalent to 8 + 1 ⁄ 2 in × 12 in (220 mm × 300 mm) and ANSI A (alias US Letter) is defined as 8 + 1 ⁄ 2 in × 11 in (220 mm × 280 mm).

  6. Paper size - Wikipedia

    en.wikipedia.org/wiki/Paper_size

    The international paper size standard is ISO 216. It is based on the German DIN 476 standard for paper sizes. Each ISO paper size is one half of the area of the next larger size in the same series. ISO paper sizes are all based on a single aspect ratio of the square root of 2, or approximately 1:1.41421. There are different series, as well as ...

  7. List of measuring instruments - Wikipedia

    en.wikipedia.org/wiki/List_of_measuring_instruments

    Established standard objects and events are used as units, and the process of measurement gives a number relating the item under study and the referenced unit of measurement. Measuring instruments, and formal test methods which define the instrument's use, are the means by which these relations of numbers are obtained.

  8. Letter (paper size) - Wikipedia

    en.wikipedia.org/wiki/Letter_(paper_size)

    The precise origins of the dimensions of US letter-size paper (8.5 × 11 in) are not known. The American Forest & Paper Association says that the standard US dimensions have their origin in the days of manual papermaking, the 11-inch length of the standard paper being about a quarter of "the average maximum stretch of an experienced vatman's arms". [2]

  9. Humidity indicator card - Wikipedia

    en.wikipedia.org/wiki/Humidity_indicator_card

    As a result, an industry wide standard for packaging of semiconductors was released in 1989. This standard, EIA 583, called for the use of humidity indicator card that would indicate as low as 10%. Adherence to proper storage and handling methods immediately reduced the number of failures in the semiconductors, but over the years it became ...
