Standards
This standard is intended to satisfy the demand for basic safety information which should be understood by each paintball game participant prior to the start of the player's first game on the day of play. The information specifies rules of personal conduct, which might affect the safety of persons who are in close proximity to a paintball marker or a propellant gas storage vessel.
This practice establishes minimum safety requirements for the operation of paintball playing fields, and provides for certain materials and procedures required.
This document specifies a method for the magnetic particle testing of ferro-magnetic steel and iron castings. It also gives acceptance criteria through severity levels defined by the nature, the area and the dimensions of the discontinuities present. This document is applicable to all ferro-magnetic castings, independent of the moulding method. A steel and iron casting is considered to be ferro-magnetic if the magnetic induction is greater than 1 T
(Tesla) for a magnetic field strength of 2,4 kA/m. This document only applies to those areas of the castings specified for testing, as well as the percentage
of castings to be tested
This document specifies a method for the liquid penetrant testing of steel and iron castings.
This standard applies to the storage and handling of portable containers used for storage of Liquefied Petroleum Gases (LPG) and to the transportation of these containers.
This standard does not cover the storage, handling and transport of ammonia cylinders.
The main text of this national standard contains a list of these parameters, their units and references to measurement standards. Informative annexes give examples of typical values for these parameters, with the main emphasis on health and safety. In defining the parameters governing composition, physical properties and trace constituents, consideration has also been given to existing natural gases to ensure their continuing viability.
The question of interchangeability is dealt with in Annex A (see Clause A.2).
