1 Scope

This Part of GB 18282 specifies the requirements for chemical indicators to be used in the steam penetration test for steam sterilizers for wrapped goods, e.g., instruments and porous materials. The indicator for this purpose is a Class 2 indicator as described in ISO 11140-1. Indicators complying with this Part of GB 18282 are intended for use in combination with the standard test pack as described in EN 285. This Part of GB 18282 does not consider the performance of the standard test pack, but does specify the performance of the indicator systems.

Markings made before processing shall be legible after processing. g) It shall be of size A4 in accordance with ISO 5457.

6 Performance Requirements

6.1 The indicator shall meet the following requirements. a) It shall show a uniform color change complying with 5 e) after exposure to dry saturated steam at 134 (+1.5 0 )°C for 3.5 min ± 5 s or after exposure to dry saturated steam at 121 (+1.5 0 )°C for 15 min ± 5 s or both. Compliance shall be tested in accordance with Annex C. b) When placed in the center of a standard test pack, it shall show a non-uniform color change when the temperature at the center of the standard test pack is 2°C lower than the temperature of the chamber drain of the steam exposure apparatus (see Annex H). Compliance shall be tested in accordance with Annex I. c) It shall show no discernible color change after exposure to dry heat at (140 ± 2)°C for not less than 30 min. Compliance shall be demonstrated in accordance with Annex D. With some indicators a slight color change can occur. This shall be acceptable if the change that occurs is markedly different from that brought about by exposure to steam in accordance with 6.1 a) and within the limits specified by the manufacturer. d) It shall not visibly transfer indicator reagent to the material of the test load in intimate contact with the indicator during processing. Compliance shall be demonstrated in accordance with Annex F. 6.2 The indicator shall comply with the requirements of this part of GB 18282 for the duration of the shelf life specified by the manufacturer. If any change in the indicator occurs during ageing, it shall be different to the change on exposure to dry saturated steam [as described in 6.1 a)], and shall have either inactivated the indicator so that no further change can take place or not affected the performance of the ......
