Hello
I get advice from our supplier for below statement:
The CAFÉ test is a ANSI ESD STM 15.1 which a person wears a glove and test. It is good and not wrong. After all glove is meant to wear.
Most of time it passed well.
But when come to STM 11.11 is more stringent because now the glove is tested without a human involve. When it passed, it mean it is a good glove.
Could you please clarify the guidelines we should adhere to for qualifying our gloves and finger cots?
Erian,
ANSI/ESD S20.20 does not require product qualification or compliance verification of gloves or finger cots. If you choose to qualify gloves or finger cots I suggest using the CAFE fixture in ANSI/ESD STM15.1 rather than the ANSI/ESD STM11.11. In Annex B of ANSI/ESD STM 15.1 it states “…the intrinsic resistance test (i.e. ANSI/ESD STM11.11) does not always provide correct information on how the gloves will work in conjunction with a person as a system”. Even if ANSI/ESD STM11.11 is more stringent, it is not as realistic.
Erian,
The STM 11.11 test is included in the 15.1 document as a source of additional information for you should you want to gather such data.
As has been stated the STM15.1 test will give you an “in-use” characterization.
Best regards

Hi Andy and Matts
thanks for the explanation
Just to add, the usefulness of STM 11.11 data with the CAFE probe data is to be able to do a sample measurement on incoming gloves. The CAFE method will be the data that can be used to qualify the glove or finger cot. The 11.11 data can be used for incoming sampling of the gloves. While not required, this is a good reason to have both sets of data.
