Quality
Certifications — stated plainly
Supplier qualification runs on documents, not adjectives. This page states what we hold today, what is in progress, and what we do not hold. If a certification you need is in the third column, we would rather you know now.
What we hold
Suracsh Filters Pvt Ltd holds ISO 9001:2015 for its quality management
system — certificate Q-707024081304, issued by MyCert on 13 August 2024 and
valid to 12 August 2027 — and runs an ISO/IEC 17025 certified gas testing
laboratory. The in-house R&D unit is separately recognised by the Government of India's
Department of Scientific and Industrial Research. Respirator grades are
tested against EN 14387 and NBC grades against MIL protocol, with the breakthrough data
published on the product pages rather than issued on request.
Product standards we test against
| Standard | Applies to | Status |
|---|---|---|
| EN 14387 | Respirator filter grades — SURSORB A, AX, B, E, K, ABE, ABEK, GAM | Tested against. Breakthrough data published for SURSORB ABEK. |
| ISO/IEC 17025 laboratory | All gas-phase grades — breakthrough, capacity and characterization work | Our in-house gas testing laboratory is certified to ISO/IEC 17025, the international standard for the competence of testing laboratories, and operates to EN 14387 with ASTM methods for characterization. Testing is done in-house rather than sent out, so a custom formulation can be iterated against your duty without a third-party queue. |
| MIL standard (CBRN) | SURSORB CBRN+ (ASZM-TEDA) | Tested against. Unaged and aged breakthrough times published in full. Specific protocol issued on request. |
Management system certifications
| Certification | What it buys you | Status |
|---|---|---|
| ISO 9001:2015 |
Evidence that quality is managed by a documented, externally audited system — the
item most supplier-qualification processes check first.

Government of India, Ministry of Science and Technology — recognition of the
in-house R&D unit at Kanjikode, Palakkad. Third-party attestation that the R&D
function exists, rather than a claim that it does.

What we do provide with every shipment
- A Certificate of Analysis against the specification on the product page — see a specimen below
- Packing list, bill of lading and country-of-origin documentation
- Safety data sheet for the supplied grade
- Lot identification enabling traceability back to the production batch
Specimen Certificate of Analysis
Below is a real Certificate of Analysis for one production lot, reproduced exactly as it was issued. Customer name, date, production lot number, lab report number and order quantity are redacted; every specification, result and test method is untouched. This is the document that arrives with your container.
| Test parameter | Specification | Result | Test method |
|---|---|---|---|
| Moisture (%) | 5 max | 2.03 | ASTM D2867 |
| CTC (%) | 50 ± 2 | 50.8 | ASTM D3467 |
| pH | Alkaline | 10 | ASTM D3838 |
| Ball pan hardness (%) | 98 ± 2 | 98.85 | ASTM D3802 |
| Dry density (g/cc) | 0.490 ± 0.030 | 0.489 | ASTM D2854 |
Results are for a single lot of a made-to-specification grade and are not a published specification for any catalog grade. Ask for the current COA against the lot you are quoted.
Handling and storage
Activated carbon presents real hazards. It depletes oxygen in confined spaces, some
impregnated grades can self-heat, and dust is an inhalation and explosion consideration.
Request the safety data sheet for your grade before handling, and follow confined-space
procedure when entering any vessel that has contained carbon.
