This document describes a method for the determination of the boiling range distribution of petroleum products by capillary gas chromatography using flame ionization detection. The standard is applicable to crude oils. The boiling range distribution and recovery to C100 or C120 can be determined.

Two procedures are described: single and dual analysis mode. The basis of each is the calculation procedure as described in Annex A.

Procedure A (or Single analysis mode) determines the boiling range through C100 or C120 in a single analysis

Procedure B (or Dual analysis mode) combines procedure A with the boiling point distribution from C1 up to C9 using the Detailed Hydrocarbon Analysis (DHA) according EN 15199‑4. The results of both analyses are merged into one boiling point distribution.

NOTE 1       There is no specific precision statement for the combined results obtained by procedure B. For the precision of the boiling range distribution according to procedure B the precision statements of procedure A and EN 15199‑4 apply. No precision has been determined for the results after merging.

NOTE 2       For the purpose of this European Standard, the terms “% (m/m)” and “% (V/V)” are used to represent the mass fraction, µ, and the volume fraction, φ, of a material respectively.

This document describes the determination of boiling range distribution of materials with initial boiling points (IBP) below 100 °C and final boiling points (FBP) above 750 °C. For testing materials with initial boiling points (IBP) above 100 °C and final boiling point (FBP) below 750 °C, Part 1 of the standard may be used. For testing materials with initial boiling points (IBP) above 100 °C and final boiling point (FBP) above 750 °C, Part 2 of the standard may be used. Part 4 is used for the determination of the boiling range distribution of hydrocarbons up to n-nonane in crude oil.

WARNING — Use of this European Standard may involve hazardous materials, operations and equipment. This European Standard does not purport to address all of the safety problems associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and to determine the applicability of regulatory limitations prior to use.

This part of the ISO 14644 standards gives guidance on the interpretation and application of the results of the measurement of Particle Deposition Rate (PDR) on one, or more vulnerable surfaces in a cleanroom as part of a contamination control programme. It provides some guidance on how to influence the PDR and reduce the risk of particle contamination on vulnerable surfaces.

This standard gives information on how a cleanroom user can use the PDR measurements to determine limits that can be set for macroparticles on vulnerable surfaces. It also gives a risk assessment method by which an acceptable risk of deposition of particles onto vulnerable surfaces in a cleanroom can be established and, when this is not achieved, methods that can be used to reduce the PDR.

Note to entry: An alternative to the PDR is the particle obscuration rate which determines the rate of increase of coverage of particles onto an area of surface over time. The POR can be used in an analogous way to the PDR and the required POR for a specified surface can be calculated and the risk from deposited particles reduced.

This standard does not:

•      provide a method to classify a cleanroom with respect to PDR or POR,

•      directly consider the deposition of microbe-carrying particles (MCPs), although MCPs can be treated as particles,

•      give any consideration to surface deposition by contact as, for example, when personnel touch a product and contamination is transferred.
