SNI Compliance Guide for Hospital Materials

Selecting materials for a hospital project is fundamentally different from selecting materials for a conventional commercial or residential building.

Healthcare facilities must meet demanding requirements related to fire safety, hygiene, indoor environmental quality, durability, acoustic performance, thermal comfort, and overall building safety. In Indonesia, these requirements are supported by a range of Standar Nasional Indonesia (SNI) and other applicable building regulations and technical standards.

For architects, engineers, contractors, developers, and procurement teams, understanding SNI requirements is therefore an essential part of material selection.

More importantly, SNI compliance should not be viewed simply as a certification issue. It should be understood as part of a broader building-performance strategy.

What Does SNI Compliance Mean for Hospital Materials?

SNI, or Standar Nasional Indonesia, is the national standardization framework used in Indonesia for products, processes, services, and other technical requirements.

For building projects, different SNI standards address different aspects of construction and building performance. Therefore, there is no single SNI that automatically makes a material suitable for every application in a hospital.

Instead, the required standards depend on:

• The type of material;
• Its intended application;
• The location of the material within the building;
• The function of the space;
• Fire-safety requirements;
• Structural requirements;
• Acoustic requirements;
• Thermal performance;
• Hygiene and cleaning requirements; and
• Applicable project specifications and regulations.

This distinction is particularly important in healthcare projects because a material can comply with one technical requirement while still being unsuitable for a particular application.

Key SNI Considerations for Hospital Materials

When selecting materials for healthcare facilities, several areas of performance deserve particular attention.

1. Fire Safety

Fire safety is one of the most critical considerations in hospital design.

Hospitals accommodate patients who may have limited mobility or may be unable to evacuate independently. Consequently, fire protection requirements can be particularly demanding.

Indonesia's building regulations require buildings to be protected against fire. Government guidance also identifies the use of installed building materials as one of the factors that must be considered in passive fire protection.

Relevant testing may include fire resistance and reaction-to-fire characteristics.

For example, the Indonesian building science laboratory identifies SNI 1741:2008 for fire-resistance testing of structural building components. Testing can be applied to components such as walls, floors, doors, beams, and columns.

For hospital materials, project teams should therefore evaluate:

• Fire resistance;
• Combustibility;
• Ignitability;
• Smoke and fire behavior;
• Fire stopping performance; and
• Performance of the complete building assembly.

A material's fire performance should always be assessed according to its intended application and the requirements of the relevant building system.

2. Acoustic Performance

Noise control is another important consideration in healthcare facilities.

Patient rooms, consultation rooms, treatment areas, operating environments, and staff spaces may require appropriate acoustic separation and noise control.

The Indonesian building science laboratory notes that acoustic performance is part of the technical requirements for building reliability and recommends considering appropriate materials from the design stage. Acoustic performance of partitions can be expressed using metrics such as Sound Transmission Class (STC) or Weighted Sound Reduction Index (Rw).

For hospital projects, acoustic evaluation may therefore include:

• Airborne sound insulation;
• Sound absorption;
• Impact sound;
• Mechanical and equipment noise; and
• Speech privacy.

Importantly, acoustic performance should be evaluated at the assembly level rather than based solely on the specification of an individual material.

A high-performance board, panel, or insulation product cannot guarantee high acoustic performance if the complete wall system contains weak points such as unsealed joints, doors, glazing, or service penetrations.

3. Thermal Performance

Healthcare buildings operate continuously and generally require carefully controlled indoor temperatures.

Thermal performance therefore has implications not only for occupant comfort but also for energy consumption and HVAC operating costs.

Building materials can influence heat transfer through walls, roofs, floors, windows, and other parts of the building envelope.

Relevant performance parameters may include:

• Thermal conductivity (λ);
• Thermal resistance (R-value);
• Thermal transmittance (U-value); and
• Overall thermal performance of the building envelope.

Indonesia's building science laboratory provides thermal transmittance testing as part of its building-material testing services.

For hospital projects, material selection should therefore consider how the material contributes to the thermal performance of the complete building envelope.

4. Structural and Seismic Requirements

Hospital buildings must also satisfy structural safety requirements.

Indonesia is located in an area with significant seismic activity, making earthquake-resistant design an important consideration for many building projects.

For example, SNI 1726:2019 establishes requirements for earthquake-resistant design of building and non-building structures.

For materials used in walls, partitions, ceilings, facades, and other building components, designers should therefore consider:

• Structural loads;
• Seismic movement;
• Connections and anchoring;
• Material weight;
• Deformation compatibility; and
• Performance of the complete assembly.

A lightweight material, for example, may provide advantages in reducing dead load, but its connection and anchoring system must still be appropriately designed.

SNI Compliance Is Not the Same as Product Suitability

One of the most important points for hospital procurement teams is that SNI compliance does not automatically mean that a product is suitable for every hospital application.

Consider an acoustic wall material.

A product may have excellent sound absorption properties, but sound absorption is different from sound insulation. Similarly, a material may have good thermal conductivity characteristics but not provide the required fire resistance when incorporated into a particular wall assembly.

Therefore, procurement teams should distinguish between:

Product performance → Assembly performance → Building performance

These three levels are related but not interchangeable.

Test Reports and Technical Documentation

For a hospital project, technical documentation is an important part of material evaluation.

Depending on the product and application, manufacturers may be expected to provide documentation such as:

• SNI certification, where applicable;
• Laboratory test reports;
• Fire-resistance test results;
• Acoustic test results;
• Thermal-performance test results;
• Product technical data sheets;
• Material safety information;
• Installation guidelines;
• Quality-management certifications; and
• Environmental or sustainability documentation, where relevant.

The Indonesian building science laboratory, for example, provides testing services for fire resistance, material combustibility, acoustic performance, STC, sound absorption, and thermal transmittance.

This demonstrates an important principle: technical performance should be supported by measurable test data rather than marketing claims alone.

A Practical SNI Compliance Checklist

Before approving a building material for a healthcare project, the project team can use the following checklist.

Product Compliance

• Does the product have an applicable SNI?
• Is SNI certification mandatory for this product?
• Is the certificate current?
• Does the certificate apply to the exact product and manufacturer?
• Are the product specifications consistent with the certificate?

Fire Performance

• Has the material been tested for fire performance?
• Is the required fire-resistance rating achieved?
• Does the complete assembly meet the required performance?
• Are joints, penetrations, and connections properly addressed?

Acoustic Performance

• Is sound absorption required?
• Is sound insulation required?
• What STC or Rw performance is required?
• Has the complete partition system been tested?

Thermal Performance

• What is the material's thermal conductivity?
• What thermal resistance does the assembly provide?
• How does the material contribute to the building's overall thermal performance?
• Can it help reduce HVAC loads?

Healthcare-Specific Requirements

• Can the surface be cleaned and disinfected effectively?
• Is the material sufficiently durable for the intended environment?
• Is it resistant to moisture where required?
• Does it meet relevant hygiene and infection-control requirements?
• Does it produce undesirable emissions that could affect indoor air quality?

Documentation

• Product data sheet;
• Certificate of conformity or SNI certification, where applicable;
• Laboratory test reports;
• Installation documentation;
• Quality-control documentation; and
• Environmental documentation, where relevant.

Beyond SNI: Evaluating the Total Performance of a Material

SNI compliance is an essential starting point, but high-performance healthcare projects should go further.

A material should ideally be evaluated based on its contribution to the building's overall performance.

For example, a wall system could potentially contribute simultaneously to:

Fire Safety + Acoustic Insulation + Thermal Insulation + Durability + Indoor Environmental Quality

This integrated approach is particularly valuable for healthcare buildings because every square meter of wall, floor, ceiling, and roof represents an opportunity to improve building performance.

Rather than asking only:

“Is this material SNI compliant?”

a more comprehensive question is:

“Does this material meet the applicable standards and contribute to the required performance of the healthcare facility?”

That shift in perspective can lead to better material decisions.

Green Building and SNI Compliance

SNI compliance and green building objectives should also be considered together.

Indonesia has established technical guidance for evaluating the performance of green buildings, including through Minister of Public Works and Housing Circular Letter No. 01/SE/M/2022 on Technical Guidelines for Green Building Performance Assessment.

A material can therefore be evaluated not only for regulatory compliance but also for its contribution to:

• Energy efficiency;
• Water efficiency;
• Resource efficiency;
• Indoor environmental quality;
• Durability;
• Waste reduction; and
• Life-cycle performance.

This creates an opportunity to move beyond a simple compliance-based approach toward a high-performance building strategy.

Conclusion

Selecting materials for healthcare facilities requires a careful balance between regulatory compliance, safety, performance, durability, and sustainability.

SNI standards provide an important technical foundation, but hospital material selection should not stop at checking whether a product carries an SNI certificate.

The more important question is whether the product, building assembly, and overall system can deliver the required performance for the specific healthcare application.

By combining applicable SNI requirements with verified laboratory data and a comprehensive assessment of fire, acoustic, thermal, hygiene, durability, and environmental performance, healthcare projects can achieve a higher level of reliability and long-term value.

Ultimately, the objective is not simply to select materials that comply with standards.

The objective is to select materials that perform to the standards—and help the building perform better.
