What a grade designation is for
A designation gives buyer and supplier a shared label for a proposed abrasive grade. It helps narrow the discussion and link an enquiry to a datasheet. It is most useful when the manufacturer, document revision and product form are also identified.
A label on its own does not describe every property that matters at the machine. Two offers carrying similar shorthand still need to be compared through their respective specification systems and supporting documents.
W1.5 is used on this site only as an example configuration. It is not presented as a stock commitment or a universal process recommendation.
Example grade configuration; final grade, tolerance and packaging confirmed at quotation.
What the label cannot establish by itself
| Specification question | Why the designation is not enough | What closes the gap |
|---|---|---|
| How is the grade defined? | The shorthand does not explain the producer’s designation system or acceptance criteria. | The selected partner factory’s current datasheet and stated grade definition. |
| How is size characterised? | A label does not provide the characterisation method or the full distribution. | The measurement method and batch information available from the manufacturing partner. |
| What else is in the paste? | The grade label does not define diamond content, carrier chemistry or consistency. | The product datasheet and the formulation details agreed for the order. |
| Will it fit the process? | Substrate, lap, applicator, fluids, cleaning and inspection all affect suitability. | A process review and, where useful, a buyer-side sample evaluation. |
| What arrives with the order? | The label does not define container, label, batch documents or dispatch paperwork. | The written quotation and order confirmation. |
Why the datasheet and the label must stay together
Always read a designation in the context of the document that defines it. Check the partner factory’s identity, product family, grade designation, document date or revision, and the measurement terms used. If any of these are missing, ask for clarification before comparing offers.
For repeat supply, keep the accepted datasheet and sample record with the purchase specification. If the manufacturing partner changes a designation, method or document, the supply route should be reviewed rather than assuming the old and new labels are interchangeable.
Xintai coordinates this document trail as an independent supply partner. We do not issue our own material test certificates or replace the manufacturing partner’s characterisation with an unverified value.
What to confirm before ordering
- The complete grade designation and the partner factory’s designation system.
- The current datasheet revision and the stated characterisation method.
- Carrier, consistency and any other paste properties relevant to the process.
- The accepted sample configuration and how it maps to the order.
- Grade tolerance, packaging, labelling and batch documents confirmed at quotation.
- The route for approving any document or specification change before repeat supply.
Sources and notes
This article explains a documentation method, not a universal grading standard. No external standard is cited, and no particle-size, concentration or tolerance value is inferred from the example designation. Order-specific values must come from the selected partner factory’s current documents.
