Summary of UN - ST/SG/AC.10/C.3/2003/51

Alternatives to the Waterbath Test for Aerosol Dispensers

Transmitted by the European Aerosol Federation (FEA)

Executive summary

Every filled UN 1950 aerosol is subjected to a test performed in a hot water bath. This requirement is laid down in 6.2.4.

This document proposes to separate requirements for UN 1950 aerosols from requirements for small receptacles containing gas (UN 2037 gas cartridges) and to include requirements for alternatives to the water bath test for aerosol dispensers.

The Burgoynes Verification Report describes how the Aerocan Leak Detector complies to the British Aerosol Manufacturers (BAMA) standard, including its safety and zoning requirements. It also details how the leak detector complies to the requirements of ADR 2007 for use as part of the water bath alternative.

The machine as supplied by Raupack designated Aerocan 100 (the machine) is capable of fulfilling the requirements of ADR 2007 of a leak tester for filled aerosols as part of the approved alternative to the Water Bath method.

METHOD 25A - DETERMINATION OF TOTAL GASEOUS ORGANIC

CONCENTRATION USING A FLAME IONIZATION ANALYZER

1.0 Scope and Application.

1.1 Analytes.

Analyte CAS No. Sensitivity

Total Organic Compounds

1.2 Applicability. This method is applicable for the

determination of total gaseous organic concentration of

vapors consisting primarily of alkanes, alkenes, and/or

arenes (aromatic hydrocarbons). The concentration is

expressed in terms of propane (or other appropriate organic

calibration gas) or in terms of carbon.

1.3 Data Quality Objectives. Adherence to the

requirements of this method will enhance the quality of the

data obtained from air pollutant sampling methods.

2.0 Summary of Method.

2.1 A gas sample is extracted from the source through

a heated sample line and glass fiber filter to a flame

ionization analyzer (FIA). Results are reported as volume

concentration equivalents of the calibration gas or as

carbon equivalents.

Analysis Systems for VOC Compliance Testing of

Bakeries

1.0 Background

Performance testing of volatile organic compounds (VOC) destruction devices such as

thermal oxidizers and catalytic oxidizers require simultaneous measurements of nonmethane

hydrocarbons (NMHC) in the gas streams entering and exiting the destruction

device. In the past, continuous total hydrocarbon measurements employing testing

protocol in accordance with U.S. EPA Test Method 25A (Gaseous Organic Concentration

- Flame Ionization) has been combined with laboratory analysis of grab samples taken

hourly. This approach has been demonstrated to be labor intensive, costly and does not

provide real-time measurements necessary to evaluate the performance of the thermal or

catalytic oxidizer.
