Polyethylene Sheet for Use in Building Construction
1.1
This standard applies to flexible sheet material made from low-density
polyethylene, primarily intended for use in building construction to retard the
passage of moisture and water vapor. The purpose of this standard is to
control the thickness of polyethylene sheet material and to provide a basis for
its procurement.

Material to this standard may also be suitable for use as a vapor…
Personal eye-protectors — Filters and eye-protectors against laser radiation
Specifies requirements for spectacle filters and protectors within the spectral region 0,2 to 1000 micron. The work, which was staggered over several years, represents a basic study for which a majority consensus was reached at the international level. To take account of new developments and knowledge relating to lasers a revision of this standard will be undertaken.
The Standard specifies the following characteristics of the oil. Appearance: Clear, mobile liquid. Colour: Pale yellow to pale brownish yellow. Odour: Characteristic of oil of Ceylon citronella. Relative density at 20/20 °C: 0,894 - 0,910. Refractive index at 20 °C: 1,4790 - 1,4870. Optical rotation at 20 °C: Range from - 22 to - 12 . Miscibility with 80 % (V/V) ethanol at 20 °C: 1 : 2.
