Key Takeaways
- ISO sets the baseline, not the hazard test. ISO 13688 covers general requirements such as ergonomics, sizing, ageing and manufacturer marking, and is used only alongside a hazard-specific standard, never on its own (ISO 13688:2013).
- Type 4, 5 and 6 are hazards, not tiers. Type 4 (EN 14605) is spray-tight, Type 5 (EN ISO 13982) is particle-tight, and Type 6 (EN 13034) is limited liquid splash: they test different threats, not stronger versions of the same one (peer-reviewed review of chemical protective clothing standards).
- Surgical gowns use two non-interchangeable systems. The US ANSI/AAMI PB70 grades liquid barrier performance across four levels, and only Level 4 is tested for viral penetration using ASTM F1671 (CDC PPE-Info).
- BIS licensing is now compulsory in India. Twelve protective-textile items were brought under Quality Control Orders effective 7 October 2023, requiring a BIS licence and Standard Mark for the domestic market (Press Information Bureau).
- A standard number is only as good as its test report. IS 17423 for bio-protective coveralls specifies blood and viral penetration resistance, breathability, seam strength and biocompatibility, all of which should be evidenced by an accredited laboratory report (Bureau of Indian Standards).
If a supplier’s spec sheet quotes ISO 13688, EN 14126 or IS 17423, what has actually been certified, and what still has to be verified before you sign a purchase order? The short answer: each of those codes tests a different, specific thing, and a certification code should always be supported by accredited test documentation. ISO standards set the international baseline, EN standards map to defined hazard types, medical wear is graded under its own separate systems, and BIS licensing has been legally required for protective textiles sold in India since October 2023.
For procurement managers, EHS officers and government tender evaluators, this is not academic. Writing a specification against the wrong standard, accepting a marketing claim in place of a laboratory report, or missing the BIS licence requirement can each cause a rejected consignment, a failed audit or a non-compliant tender bid. This guide breaks down what ISO, EN and BIS standards each certify for disposable protective clothing, and gives you a verification checklist to use before releasing a bulk order.
Dispowear Protection manufactures over 3 million disposable garments every month using in-house nonwoven capabilities, serving pharmaceutical companies, hospitals and healthcare distributors across India and overseas under ISO 13485 and US FDA-registered manufacturing.
A standard number on a spec sheet only means something when it is tied to a specific, verifiable test carried out by an accredited laboratory. It is not a general safety promise, and it is not a logo. The most common procurement mistake is treating a printed code, or a CE-style mark, as proof of performance rather than asking for the underlying test report that the code is supposed to represent.
This matters because substandard and misrepresented protective clothing is a documented problem in the PPE supply chain, especially during demand surges when buyers move fast and paperwork gets waved through. Misrepresented certification claims have been reported in the PPE supply chain, and a garment can carry an impressive-looking claim while having never been tested against the standard it names. The defence is simple in principle: evaluate the supporting test report alongside the certification claim. Ask for the specific standard number, the issuing accredited lab, the test date and the lot the report covers, then confirm that the certified fabric and construction are the same as what will actually ship.
The three standards families you will meet on a disposable-PPE spec sheet, ISO, EN and BIS, each answer a different question. ISO and EN tell you how the garment performs against a hazard. BIS tells you whether it is legally allowed to be sold in India. You need to read all three correctly, because a garment can be genuinely well-tested internationally and still be non-compliant for domestic sale, or the reverse.
ISO 13688 is the foundation that sits under almost every coverall certification, and it is deliberately not a hazard test. It sets general requirements: ergonomics, innocuousness, size designation, ageing, compatibility, manufacturer marking, and the information that must be supplied with the garment. Critically, the standard is intended to be used only in combination with a hazard-specific standard, never on its own, so a claim of “ISO 13688 compliant” on its own tells you the garment is a properly designed and marked piece of protective clothing, not that it stops any particular threat (ISO 13688:2013, linked above).
On top of that baseline, ISO publishes the hazard-specific methods that the European Type system then adopts. ISO 13982-1, for example, is the international method for full-body protection against airborne solid particles, which becomes Type 5 in the EN framework. For biological and medical barrier claims, ISO methods such as resistance to penetration by blood and body fluids, and resistance to penetration by blood-borne pathogens using a bacteriophage challenge, are the underlying tests that EN 14126 and AAMI PB70 both draw on. The point for a buyer is that ISO methods are the common technical language: when two suppliers quote different regional standards, they are often referencing the same ISO test underneath.
Because ISO standards are the international baseline rather than a legal requirement in any single market, an ISO reference on a spec sheet is best read as a floor, not a finish line. It confirms the garment was made and marked to a recognised general standard. What it does not tell you is which hazard the garment resists, or whether it may legally be sold in your market. For that you have to read the EN Type and, for India, the BIS licence.
The Type numbers you see on coveralls, Type 4, Type 5, Type 6, are not marketing tiers and they are not a simple ranking from weakest to strongest. Each Type maps to a specific EN standard testing a specific hazard. A Type 5 garment is not a “better” Type 6; it protects against a different threat. Reading them as a ladder is one of the most expensive misunderstandings in PPE procurement, because it leads buyers to over-specify, under-specify, or accept a garment tested for the wrong hazard entirely.
The mapping is well established in the occupational-hygiene literature: Type 4 corresponds to EN 14605 (spray-tight suits with sealed seams, for splashes of liquid chemical not under pressure), Type 5 to EN ISO 13982 (protection against airborne solid particles), and Type 6 to EN 13034 (limited protection against light liquid splash and mist), as set out in the peer-reviewed review “Current global standards for chemical protective clothing” (linked above). Two further EN standards matter for regulated buyers. EN 14126 covers protection against infective biological agents and is applied as a suffix to the base Type (for example Type 5-B or Type 6-B), so a biological claim is only valid when combined with a barrier Type. EN 1149 covers electrostatic properties, which is the relevant standard for cleanroom, electronics and flammable-atmosphere environments where static discharge is a hazard.
| Coverall Type | Governing EN standard | Protects against |
|---|---|---|
| Type 4 | EN 14605 | Spray-tight: saturation splashes of liquid chemical not under pressure, sealed seams |
| Type 5 | EN ISO 13982 | Particle-tight: airborne solid particulate (dusts, powders, fibres) |
| Type 6 | EN 13034 | Limited splash: light spray and mist, occasional low-volume liquid contact |
| Type 5-B / 6-B | EN 14126 (with base Type) | Infective biological agents, applied as a suffix to a barrier Type |
| Antistatic | EN 1149 | Electrostatic dissipation for cleanroom, electronics and flammable atmospheres |

Surgical gowns and isolation wear are tested differently from industrial coveralls, and the two dominant systems are not interchangeable. In the United States, ANSI/AAMI PB70 classifies protective apparel and drapes by liquid barrier performance across four levels, with Level 1 the lowest and Level 4 the highest. The distinction that trips up buyers: only Level 4 gowns are tested for viral penetration, using ASTM F1671, so only a Level 4 garment can be described as resistant to blood-borne viral penetration. Levels 1 to 3 are challenged with water-based tests only (ANSI/AAMI PB70, per CDC PPE-Info as linked above).
In Europe, EN 13795 governs surgical gowns, drapes and clean air suits used as medical devices. Rather than four numbered levels, it classifies products as “standard performance” or “high performance”, and separates the critical product area, where contact with fluid and pathogens is most likely, from the less critical area, applying tighter requirements to the critical zone. It tests characteristics such as resistance to microbial and liquid penetration, cleanliness in terms of particles and microbes, linting, and burst and tensile strength both dry and wet.
Because the two systems use different classification logic and different test challenges, a gown tested to AAMI PB70 Level 3 is not automatically equivalent to any EN 13795 class, and vice versa. If you are sourcing gowns for a hospital that specifies one system, ask which system the gown was actually tested against, and do not accept a cross-mapping unless the supplier provides test data for the system you require. This is a common and costly procurement error precisely because the two look similar on a datasheet.
For anything sold into India, the decisive question is not “which ISO or EN standard” but “does it hold a BIS licence”. Under the protective-textiles Quality Control Orders, BIS licensing became compulsory, not optional, for the domestic market. The Ministry of Textiles brought twelve protective-textile items under Quality Control Orders in Phase I, and these took effect from 7 October 2023, requiring manufacturers, including foreign manufacturers exporting into India, to obtain a BIS licence and carry the Standard Mark (Press Information Bureau, Government of India, linked above). An international CE-style or EN claim, however genuine, does not by itself make a garment legally saleable in India once its category is under a Quality Control Order.
The specification standards themselves are published by the Bureau of Indian Standards. IS 17423 covers bio-protective coveralls, in single-use and reusable forms, and specifies resistance to synthetic blood penetration, resistance to viral penetration, breathability, tensile strength, seam strength, microbial cleanliness and biocompatibility. IS 16289 covers surgical face masks, specifying bacterial filtration efficiency and sub-micron particulate filtration efficiency around 0.1 micron, differential pressure for breathability, and splash resistance, across defined performance classes. IS 17334 covers surgical gowns and drapes, testing blood and viral resistance, particle release, tensile and bursting strength, and microbial penetration resistance (Standards for Medical Textiles, Bureau of Indian Standards, linked above).
A BIS licence number is more meaningful than a self-declared claim because it is traceable. It confirms that a specific manufacturer, for a specific product, has been assessed against the named Indian Standard and is authorised to use the Standard Mark. When you evaluate an Indian-market supplier, the BIS licence number is the single most important thing to verify, and it can be checked against the Bureau’s own records rather than taken on trust from a printed mark.
Standards knowledge only pays off at the point of purchase. Before releasing a bulk order for disposable protective clothing, work through five checks.
As context for what compliance-readiness looks like on the supply side, Dispowear has manufactured to international safety standards for two decades and has held US FDA licensing since 2008, running two dedicated manufacturing facilities. That is the kind of documented, traceable manufacturing base a regulated buyer should expect to see evidenced, not just claimed. You can review our manufacturing standards, browse our coverall range and surgical and isolation gowns, or see the wider GMP requirements for disposable coveralls.
Indicative parameters buyers typically confirm on the datasheet for a standards-compliant disposable garment programme:
| Parameter | Typical specification |
|---|---|
| Base fabric | Virgin-polypropylene SBPP; SMS or laminated constructions where higher barrier is required |
| GSM range | Configurable by application (lighter for comfort in low-risk areas, heavier for barrier-critical use) |
| General requirement | Designed and marked to ISO 13688 general-requirements principles (ergonomics, sizing, ageing, marking) |
| Hazard classification | Coveralls specified to the relevant Type (EN ISO 13982 Type 5, EN 13034 Type 6) or EN 14126 biological where required |
| Medical / surgical | Gowns to EN 13795 or AAMI PB70 level, and IS 17423 / IS 17334 for the Indian market |
| Anti-static option | EN 1149 electrostatic treatment for cleanroom, electronics and flammable-atmosphere use |
| Sterility | Non-sterile, or ethylene-oxide / gamma-sterilised with a stated sterility assurance level |
| Documentation | Certificate of analysis, fabric test reports, GSM data and lot traceability per batch; BIS licence for Indian-market categories |
Figures are indicative and confirmed on the product datasheet and test reports for each order.
ISO standards set the international baseline, EN Type standards map to specific hazards (Type 4 spray, Type 5 particle, Type 6 splash, plus EN 14126 biological and EN 1149 antistatic), medical wear is graded under separate and non-interchangeable systems in EN 13795 and AAMI PB70, and BIS licensing is now compulsory for protective textiles sold in India. The discipline that protects your order is the same across all three families: specify the standard that matches the real hazard, then verify it with an accredited test report and, for India, a valid BIS licence, rather than trusting a mark on a datasheet.
Whether you require disposable coveralls, surgical gowns, isolation gowns, or cleanroom apparel, our regulatory and technical team can help you identify the appropriate ISO, EN, BIS, or customer-specific compliance requirements.
Request technical documentation, product samples, or a customized quotation to ensure the right certification for your application and market.
For the categories brought under the protective-textiles Quality Control Orders, yes. Twelve protective-textile items became subject to compulsory BIS licensing effective 7 October 2023, meaning a BIS licence and Standard Mark are required for the domestic market. An international ISO or EN claim alone does not make such a product legally saleable in India once its category is notified. Confirm the exact category and its licence status before contracting.
They protect against different hazards, not different strengths of the same hazard. Type 5 (EN ISO 13982) protects against airborne solid particles such as dusts and powders, while Type 6 (EN 13034) offers limited protection against light liquid splash and mist. A Type 5 suit is not a “stronger” Type 6, so specify by the hazard your workers actually face.
No. They are separate classification systems for surgical gown and drape barrier performance, EN 13795 in Europe and ANSI/AAMI PB70 in the United States. PB70 uses four numbered levels, with only Level 4 tested for viral penetration, while EN 13795 uses standard and high-performance classes with critical and less-critical zones. A gown tested to one system is not automatically certified under the other, so ask which system it was tested against.
IS 17423 specifies resistance to synthetic blood penetration, resistance to viral penetration, breathability, tensile strength, seam strength, microbial cleanliness and biocompatibility, for single-use and reusable bio-protective coveralls. It is the Indian Standard a bio-protective coverall must meet for BIS certification, and the individual test results should be evidenced by an accredited laboratory report.
Request the specific standard number, the accredited testing laboratory’s report with a test date and the lot it covers, and, for Indian-market sales, the BIS licence number that can be checked against the Bureau’s own records. Rely on the traceable documentation, not a printed logo, and confirm that any customization such as lamination or a GSM change was re-tested against the relevant standard.
