处理物品的微生物测试

拥有超过30年的开发人员支持经验, 制造商, 以及处理过的物品的营销者, im体育APP’s consultative antimicrobial 和 regulatory experts can help you successfully navigate the complex regulations for making claims for treated articles.

Items treated with antimicrobial products intended to protect the article itself are considered to be treated articles. Examples of treated articles include textiles, paints, 和 rubber gloves. im体育APP has extensive experience testing a wide variety of treated articles to established methodology. Leading organizations partner with us to ensure their products meet the criteria for making claims.

我们可以用我们网站上没有列出的方法来测试产品. 如果你没有看到你感兴趣的方法， 今天就与我们联系 探索替代方法. 在微生物学和病毒学方面有几十年的经验, 我们的团队可以开发定制协议来满足您的特定需求.

抗菌物品检测

按下列标准测试方法对处理过的物品进行im体育APP测试:

ASTM E2149 St和ard Test Method for Determining the 抗菌 Agents -用这种方法, treated test samples are placed in a laboratory flask containing a dilute suspension of test organism, 一般 大肠杆菌. The flask is placed onto a wrist-action shaker 和 shaken for a desired exposure time, 通常是1小时. 曝光后, a sample of the test organism suspension is removed quantitatively assayed for survivors. 将得到的盘子孵育, the number of survivors is enumerated 和 a percent reduction is determined for the test flask as compared to the untreated control suspension.

No regulated reduction limits currently exist for general antimicrobial claims made using this method.

ASTM E2180 St和ard Test Method for Determining 抗菌 Activity in Polymeric or Hydrophobic Materials -用这种方法, treated test samples are inoculated with the test organism mixed with in a semi-solid agar “slurry” to facilitate surface interaction. The test organism is allowed to expose on the surface of the treated material 通常是24小时. 曝光后, 样品被中和, the surface is washed 和 the sample is quantitatively assayed for survivors. 将得到的盘子孵育, the number of survivors is enumerated 和 a percent reduction is determined for the test sample as compared to the untreated control sample.

No performance criteria currently exist for general antimicrobial claims made using this method. 在本方法中使用的常见试验生物包括 金黄色葡萄球菌，假单胞菌 绿脓杆菌 和 肺炎克雷伯菌.

AATCC 100纺织材料抗菌整理剂的评定 -用这种方法, treated test samples 和 untreated control samples are inoculated with a representative test organism, 一般 金黄色葡萄球菌 和 肺炎克雷伯菌. The test organism is allowed to expose to the test material at an elevated temperature, 通常是24小时. 曝光后, the samples are neutralized 和 quantitatively assayed for survivors. 将得到的盘子孵育, the number of survivors is enumerated 和 a percent 和 log₁₀ reduction is determined for the treated test material as compared to the untreated control material.

No regulated reduction limits currently exist for general antibacterial claims made using this method.

织物或硬表面防霉试验 -用这种方法, ceramic tile or cotton muslin carriers are treated with the product 和 the carriers are allowed to dry. 干燥后，载体接种黑曲霉. The treated carriers are incubated in a high humidity environment 和 are visually rated for mold growth.

一种产品被认为是有效的防霉剂, the treated surfaces must demonstrate no mold growth following incubation.

JIS Z 2801/ISO 22196- Japanese Industrial St和ard (JIS) Z 2801 Test for Determining 抗菌 Activity - The purpose of this test is to determine the antimicrobial activity on the surface of a product following the Japanese Industrial St和ard (JIS) Z 2801 method. This method is also in compliance with the ISO 22196 International St和ard.

An aliquot of test organism is exposed to a surface-bound antimicrobial agent. 暴露后，物质被中和，并对幸存者进行检测. 适当的培养纯度, 不育, 最初的悬架, 采用不锈钢控制和中和控制.

This study is designed to examine the rate-of-kill of a test substance following exposure to the test organism suspension to the test carrier. 结果以测试生物体的百分比和对数减少表示. Minimum percent 和 log reduction values do not exist to specify a “passing” or “failing” test substance, 在许多情况下，合格或不合格由担保人决定.
