Hygiena have the following email listed as 'International' contact for Cleaning Verification Products. I would try that, they will likely direct you to the relevant people. I deal with Hygiena (UK) and have always found them very helpful.

Regarding requirements - for BRC at least - have a look at clause 4.11.3:
Limits of acceptable and unacceptable cleaning performance shall be defined for food contact surfaces
and processing equipment. These limits shall be based on the potential hazards relevant to the product or
processing area (e.g. microbiological, allergen, foreign-body contamination or product-to-product
contamination). Therefore, acceptable levels of cleaning may be defined by visual appearance, ATP
bioluminescence techniques (see glossary), microbiological testing, allergen testing or chemical testing
as appropriate.
From the I.G:
The limits need to be based on risk, and this should be used for assessing whether the cleaning undertaken
is of an acceptable standard. Acceptable limits may be based on visual inspection, ATP monitoring or
specific analysis such as microbiological, allergen or chemical testing. For example, where the cleaning is
principally designed to provide a clean processing environment, an assessment of ‘visually clean’ may be
sufficient. However, where the level of cleaning is to ensure a sterile food contact surface to make sure that
all traces of an allergen have been removed or to prevent cross-contamination of different meat species,
the level of acceptable cleaning performance may need to be based on more rigorous checks such as the
results of ATP, microbiological or allergen tests.
As you see from above, it depends on your product/process and thus RA
