| 1 | The standard was originally published in 1982. While reviewing the standard, it was decided to revise this standard by adopting ISO 7057: 1981 in order to maintain uniformity in the product worldwide and also to facilitate global trade. | |
| 2 | The requirements are applicable to filter funnels intended for use with aqueous solutions at temperatures between 0 and 60 C. Before using these filter funnels for strong acids and alkalis, oxidizing agents or non-aqueous liquids, or at temperatures outside this temperature range, users should satisfy themselves that the filter funnels are suitable for such applications either by laboratory tests or by reference to the manufacturer or supplier. Plastics filter funnels comply with the requirements of this Standard are marked both with a recommended maximum temperature of use and an indication of the material of construction. | |
