Steel and iron castings — Magnetic particle testing
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

Specification for Natural gas - Quality designation
This national standard specifies the
parameters required to describe finally processed and, where required, blended
natural gas. Such gas is referred to subsequently in this text simply as
“natural gas”.
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).

Natural gas - Natural gas for use as a compressed fuel for vehicles - Part 1: Designation of the quality
The aim of this part of ISO 15403 is to
provide manufacturers, vehicle operators, fuelling station operators and others
involved in the compressed-natural-gas vehicle industry with information on the
fuel quality for natural gas vehicles (NGVs), required to develop and operate
compressed-natural-gas vehicle equipment successfully.
Fuel meeting the requirements of this part of ISO 15403 should:
(a) provide for the safe operation of the vehicle and associated equipment needed for its fuelling and maintenance;
(b) protect the fuel system from the detrimental effects of corrosion, poisoning, and liquid or solid deposition;
(c) provide satisfactory vehicle performance under any and all conditions of climate and driving demands.

Some aspects of this part of ISO 15403 may also be applicable for the use of natural gas in stationary combustion engines.
