  2. Quality control system for paper, board and tissue machines

    en.wikipedia.org/wiki/Quality_control_system_for...

    Sensors measuring the paper quality (online meters) are attached to a sensor platform that move across the web guided by the scanner beam. A typical crossing time for a sensor platform is 10–30 s (an 8 m web, 60 cm/s). The sensor platform scans across the paper web and continuously measures paper characteristics from edge to edge.

  3. Paper and ink testing - Wikipedia

    en.wikipedia.org/wiki/Paper_and_ink_testing

    Ink requirement is defined as the amount of ink needed to print a unit area with a standard Solid Ink Density. For newsprint, the ISO 12647-3 specification is C 0.90, M 0.90, Y 0.90 and K 1.10, Status E, D50, 2o, density minus paper with polarization filter. Ink requirement is measured as g/m2 (grams of ink required to print 1 m2 of paper)

  4. Bristol board - Wikipedia

    en.wikipedia.org/wiki/Bristol_board

    Common sizes include 22 + 1 ⁄ 2 in × 28 + 1 ⁄ 2 in (572 mm × 724 mm) and its bulk thickness is 0.006 inches (0.15 mm) or higher [2] and A4, A3, A2 and A1. [ 3 ] [ 4 ] Bristol board may be rated by the number of plies it contains, basis weight , or, in Europe, by its grammage of 220 to 250 g/m 2 .

  5. Paperboard - Wikipedia

    en.wikipedia.org/wiki/Paperboard

    While there is no rigid differentiation between paper and paperboard, paperboard is generally thicker (usually over 0.30 mm, 0.012 in, or 12 points) than paper and has certain superior attributes such as foldability and rigidity. According to ISO standards, paperboard is a paper with a grammage above 250 g/m 2, but there are exceptions. [1]

  6. Unified Diagnostic Services - Wikipedia

    en.wikipedia.org/wiki/Unified_Diagnostic_Services

    Unified Diagnostic Services (UDS) is a diagnostic communication protocol used in electronic control units (ECUs) within automotive electronics, which is specified in the ISO 14229-1. [1] It is derived from ISO 14230-3 ( KWP2000 ) and the now obsolete ISO 15765 -3 (Diagnostic Communication over Controller Area Network (DoCAN) [ 2 ] ).

  7. Recycling codes - Wikipedia

    en.wikipedia.org/wiki/Recycling_codes

    Recycling codes on products. Recycling codes are used to identify the materials out of which the item is made, to facilitate easier recycling process.The presence on an item of a recycling code, a chasing arrows logo, or a resin code, is not an automatic indicator that a material is recyclable; it is an explanation of what the item is made of.

  8. White-lined chipboard - Wikipedia

    en.wikipedia.org/wiki/White-lined_chipboard

    1) Two or three coating layers 2) Pulp or white recovered fiber 3) Recovered fibre underliner 4) One or more layers of mixed and/or recovered fiber 5) Pulp or white recovered fiber 6) Back coating. White-lined chipboard (also referred to as WLC, GD, GT or UD) is a grade of paperboard typically made from layers of waste paper or recycled fibers.

  9. Paper density - Wikipedia

    en.wikipedia.org/wiki/Paper_density

    The density can be calculated by dividing the grammage of paper (in grams per square metre or "gsm") by its caliper (usually in micrometres, occasionally in mils). [1] The "ISO 534:2011, Paper and board — Determination of thickness, density and specific volume" indicates that the paper density is expressed in grams per cubic centimeter (g/cm ...
