Assessment of suitability for use of lighting fixtures in Cleanrooms
One of the main difficulties faced by Cleanroom users when making new purchases and investments, as well as in the change management process, is whether or not a particular material or piece of equipment can be accepted in the Cleanroom without risk to production. “ISO 14644 – Part 14, Assessment of the cleanroom suitability of equipment based on airborne particle concentration”, provides a methodology for assessing the suitability of equipment (e.g. wall panels, lighting fixtures, etc.) for use in a given Cleanroom cleanliness class classified in accordance with ISO 14644-1 standard.
About our laboratory
BNT SIGMA is an independent testing laboratory for cleanroom materials and products. In our ISO Class 2 Particle Emission Laboratory, located near Poznan, Poland, we are able to test Clenroom Lighting Fixtures intended for use in Cleanrooms ISO 3 – ISO 9. We can assist your company both in the assessment of a particular end product offered by your company, as well as in carrying out some comparative analysis e.g. during the new product development process or when searching for some alternative suppliers of materials and products for your company.
Test conditions
Stress conditions applied to the product to be tested are agreed between the laboratory and the client. Typically, vibrations present in buildings, which increase the release of particles from the lighting fixture, are introduced during the test (structure-borne noise 30-50 Hz).
The test environment meets Clenroom ISO Class 2 requirements
(it needs to be at least one ISO class higher than the Cleanroom or environment in which the tested product is to be installed).
Critical point(s) (high particle emission points) are determined after thorough scanning of the entire lighting fixture with a sampling probe connected to a laser particle counter.
The sampling time is 100 minutes – 100 individual samples are taken during the final (classification) measurement.
The measured particle concentrations are statistically processed and compared with the respective classification limits specified in ISO 14644-1.
The cleanroom suitability of the product is stated in the following way: “An assessment including and agreed upon representative mode of operation, according to ISO 14644-14 showed that equipment Z has cleanroom suitability for use within a cleanroom of ISO Class X (Y µm)”; where: X – is the ISO 14644-1 class number, Y – is the particle size range measured, Z – is the unique identification of the equipment tested (e.g. type, serial number, manufacturer).
Why is it worth working with us?
We keep abreast of changes in Cleanroom standards
We are a member of Technical Committee No. 161 for Air Conditioning and Ventilation and Technical Committee No. 317 for Indoor Air Quality at the Polish Standards Institute. In this way, we are involved in the process of developing standards of the ISO 14644 series.
We know requirements and perspectives of Cleanroom users
Our team worked in Validation amd Quality Assurance Department for leading companis in Pharmaceutical inductry. Currently at BNT SIGMA we are involved in many cleanroom validation projects for our clients from Pharmaceutical/Medical/Laboratory sectors.
We are customer oriented company
You can easily contact us and speak directly to the person responsible for carrying out the test and preparing the test report.
We operate internationally
We prepare test reports in English. We are open to cooperation with clients from within and outside the European Union.

क्लीनरूम ल्यूमिनेयर्स वे प्रकाश स्त्रोत होते हैं जिनका उपयोग क्लीनरूम्स में किया जाता है, जहाँ धूल और अन्य कणों का उत्सर्जन बेहद कम होता है। इस तरह के परिवेश में प्रकाश स्त्रोतों के लिए विशेष आवश्यकताएँ होती हैं।
क्लीनरूम ल्यूमिनेयर्स के लिए आवश्यकताएँ
क्लीनरूम ल्यूमिनेयर्स को विशेष रूप से डिजाइन किया जाता है ताकि वे कम से कम कण उत्सर्जन करें और आसानी से साफ हो सकें। ISO 14644-14 के अनुसार, ल्यूमिनेयर्स को कम पार्टिकल उत्सर्जन दर दिखानी चाहिए।
क्लीनरूम ल्यूमिनेयर्स की डिजाइन
- फ्लैट सरफेस: ल्यूमिनेयर्स का डिजाइन ऐसा होना चाहिए कि उनकी सतहें फ्लैट और चिकनी हों ताकि धूल और अन्य कण जमा न हों।
- आसानी से सफाई: ल्यूमिनेयर्स को आसानी से साफ किया जा सके, इसके लिए उन्हें डिजाइन किया जाता है।
- हाई इफिसिएंसी: ये ल्यूमिनेयर्स ऊर्जा कुशल होते हैं, ताकि क्लीनरूम के ऑपरेशनल खर्च में कमी आए।
- एंटी-ग्लेयर: चूंकि क्लीनरूम्स में काम करने वाले व्यक्तियों को लंबे समय तक प्रकाश के संपर्क में रहना पड़ता है, इसलिए ल्यूमिनेयर्स ऐसे होते हैं जो आंखों में जलन न करें।
क्लीनरूम ल्यूमिनेयर्स उत्पादक
कई कंपनियां क्लीनरूम ल्यूमिनेयर्स का उत्पादन करती हैं। इनमें से कुछ हैं:
- Philips Lighting: Philips उच्च गुणवत्ता वाले क्लीनरूम ल्यूमिनेयर्स का उत्पादन करता है जो कई क्लीनरूम आवश्यकताओं को पूरा करते हैं।
- Osram: Osram क्लीनरूम और औद्योगिक अनुप्रयोगों के लिए विशेष ल्यूमिनेयर्स प्रदान करता है।
- GE Lighting: GE विभिन्न प्रकार के क्लीनरूम ल्यूमिनेयर्स प्रदान करता है, जो उच्च दक्षता और कम कण उत्सर्जन प्रदान करते हैं।
