How to Write an RFQ for Mold-Resistant Cloth Tape and Approve a Sample

A buyer's checklist for mold-resistant cloth tape on harnesses: what to put in the RFQ, which documents to ask for and how to validate a packed harness.

Short answer: treat “mold-resistant” as a requirement with a method behind it, not as a product label. Write the method and edition into the RFQ, ask the supplier which report covers the exact model, and approve the tape on your own packed harness. For K75110-00, supplied by EJOY and made by Anhui Yijiayi, the test method can be agreed per project requirement; no test report for the model is published on this site and we do not state that it has passed any of the methods below.

What to put in the RFQ

RFQ lineWhy it matters
Test method and edition: GB/T 2423.16, IEC 60068-2-10 or ASTM G21The result of one method cannot be read as the result of another
Specimen: tape alone, tape on a named substrate, or a wrapped assemblyDecides what the report can be used for
Duration and acceptance ratingA pass needs a stated scale and limit
Storage or shipping profile: humidity, temperature, days, packagingThe real exposure the harness will see

Documents to ask for before you rely on a grade

  • The test report for the exact model and revision, with the laboratory, method, edition, date and rating.
  • The current datasheet for the model. For K75110-00 it is not published on this site yet; request it with the sample.
  • The manufacturing site’s IATF 16949 certificate, which supports the quality system within its scope and is not evidence of any test result.
  • The change-notification rule: what is notified if the backing, adhesive or finish changes.

Approve it on your own harness

  1. Wrap a representative harness or hose assembly with the sample tape.
  2. Pack it as in production and hold it at the humidity, temperature and duration of your storage or sea-freight profile.
  3. Inspect against a written criterion and keep the result with the lot record.
  4. Repeat on the trial lot before the first production release.

For the test methods themselves (what GB/T 2423.16, IEC 60068-2-10 and ASTM G21 define and how a specification names them) read the manufacturer’s mold resistance test guide. Product page: mold-resistant cloth tape K75110-00.

Frequently asked questions

Does EJOY state that its mold-resistant tape has passed GB/T 2423.16, IEC 60068-2-10 or ASTM G21?

No. The test method can be agreed per project requirement. No report for K75110-00 is published here, so we do not state a pass or a rating. Name the method and edition in your RFQ and we say what can be agreed and what you validate yourself.

Who makes the tape?

Anhui Yijiayi Technology Co., Ltd. (brand ONEI) makes K75110-00 in Mingguang, Anhui. EJOY Adhesive Technologies (HK) Limited handles RFQ, samples and export documents.

Is a lab rating on the tape enough to release a harness?

Not by itself. A rating describes a specimen under the method's conditions. Mold on a finished harness also depends on what is on its surface, the packaging and the storage or sea-freight humidity, so add a trial on the packed assembly to the approval.

What should the RFQ attach?

The drawing clause that names the mold test, the specimen type, the duration and acceptance rating, the storage or shipping profile, the width and quantity, and the approval date.
