DASM Granted 1st Extended Accreditation VILAS 1541 – Elevating Acoustic Material Testing Capabilities According to ISO/IEC 17025

DASM Institute of Acoustics Development and Application announces:

DASM Acoustics Laboratory (VILAS 1541) has been officially granted the 1st extension decision by the Bureau of Accreditation, in accordance with the international standard ISO/IEC 17025:2017.

This is an important milestone, marking the next development step of DASM in enhancing its capability material testing and acoustic inspection in Vietnam, better meeting the strict technical requirements from practical construction and industrial production.

Validity of accreditation: until July 1, 2029

Expanding the scope of advanced acoustic material testing

In this extension, DASM is supplemented and recognized for many important test methods, covering key areas in noise control and acoustic performance evaluation:

1. Measurement of noise from information technology & telecommunications equipment

Standard: ISO 7779:2018

Application: testing noise emission levels from computers, office equipment, telecommunications equipment

This is an important test to ensure electronic devices meet noise requirements in working and living environments.

2. Measurement of sound pressure levels in buildings

Standard: ISO 16032:2024

Method: Engineering method

This test helps evaluate noise levels in spaces such as offices, hotels, and apartments, thereby providing solutions to improve acoustic conditions.

3. Evaluation of acoustic performance of ducted silencers

Standard: ISO 7235:2003

Content:

• Insertion loss
• Flow noise
• Pressure loss

This is an important basis for evaluating the effectiveness of silencers in HVAC systems – a key factor in building noise control.

4. Monitoring and assessment of environmental noise

Standard: ISO 1996-2:2017

This test serves to evaluate noise in residential areas, industrial zones, and factories, contributing to ensuring compliance with environmental standards and improving the quality of life.

5. Determination of sound insulation performance of cabins

Standard: ISO 11957:1996

Application in evaluating sound insulation cabins, technical rooms, engine rooms… ensuring sound insulation effectiveness according to design requirements.

All tests are performed in a wide frequency range from 6.5 Hz to 20 kHz, including:

• Laboratory testing
• On-site testing
• Extended test methods

This allows DASM to meet a variety of measurement requirements from research, production to actual construction inspection.

Maintaining competence according to ISO/IEC 17025

Not only expanding the scope, DASM is also confirmed to continue maintaining full competence according to ISO/IEC 17025:2017 through surveillance assessment activities.

This ensures:

International standard quality management system

Accuracy and reliability of material testing results

Strictly controlled technical competence

Significance of the extension of acoustic material testing accreditation

The 1st extension of accreditation brings many important meanings to DASM as well as partners:
