SS 8760010:2016 - Healthcare textiles – Nursing beds – Burning requirements for mattresses to be used in high risk Environment (NT FIRE 055)

This method evaluates the burning behavior of mattresses intended for special purposes. The standard states the demands for basic fire requirements (flammability, smoke and heat output) of mattresses intended for care of patients who may ignite the mattress on purpose (e.g. mentally ill patients, jail interns etc ).
 

From a patient safety, and working environment point of view, it is necessary to set fire resistance requirements for nursing beds.

During a fire in a hospital ward the mattress is one of the components that constitute the greatest fire hazard because it can develop large amounts of heat and smoke.

The test is performed in accordance with NT FIRE 055. The mattress is placed on a bed frame in metal. The test assembly is placed under a hood (calorimeter) that collects all the smoke produced during the test. The ignition source, which delivers 30 kW heat output, is applied in the middle and on top of the mattress for 120 s. A possible fire in the mattress should have self-extinguished no later than 3 minutes after the burner has been removed.
To simulate arson the mattress is prepared by two incisions in the centre of the mattress cover (perpendicular to each other), so that the mattress core (foam) is directly affected by the flames from the burner.

After testing, a test report in Swedish or English is delivered with the results.

Material needed for testing:

• 1 complete mattress is needed for assessment against the requirements of SS 876 00 10.
• 3 complete mattresses are needed in case of a customer complaint dispute.

• Related standard: NT Fire 055

Reaction to fire tests – Ignitability of products subjected to direct impingement of flame – Part 2: Single-flame source test (EN ISO 11925‑2:2020)

The test method measures the ignitability of building products when exposed to a small flame. The main purpose of the test is for classification according to Euroclass B, B_fl, B_L, C, C_fl, C_L, D, D_fl, D_L, E, E_f  according to the European System. Additional test methods are also used, see EN ISO 9239-1 and EN ISO 13823.

To be able to sell a construction product in Europe, the product must be tested, classified and if possible, CE-marked in accordance with the Construction Product Regulation. To meet the technical fire requirements, there are common test methods and a common classification system, EN 13501-1, also called Euroclass. This classification system is used by all EU countries, including Norway and Iceland. In Sweden the Building Regulations, BBR, use the Euroclass system.

The test takes place inside a test chamber where the test specimen is mounted vertically. The test specimen is subjected to edge and/or surface exposure from a small gas flame. During the test, time of ignition, burning droplets and whether the flames reach the top marking of the test specimen within a prescribed time period, is registered.

A test report, in Swedish or English, is deliverd with the test results after testing.

Linear polarisation (PDP) is an electrochemical technique used to evaluate several critical phenomena associated to electrochemical processes. Corrosion can be studied with the method to determine properties such as corrosion potential, corrosion rate, polarization resistance, passivation, and pitting potential.

PDP is a commonly used electrochemical technique to characterize corrosion properties of metallic surfaces with or without protective coating in environments such as water of different salinity (marine environment), soil or battery electrolytes. It is a fast technique often used as an initial measurement of corrosion rate and the stability of protective coatings and films.

Linear polarization is performed by applying a potential with a constant sweep rate (typically 0.16 mV/s) in the range of ± 250 mV vs the open circuit potential. The direction and interval of the sweep can both be adapted for separate study of either anodic or cathodic mechanisms in detail. The changes in current with applied potential (the shape of the polarisation curve) allows for the determination of the corrosion potential, corrosion current, passivation current and breakdown potential of a passivating coating. For more detailed pitting corrosion investigations, Avesta cell measurements are available.

Testing the archival permanence and durability of recording (writing, printing and copying) on paper according to ISO 11798 is one of our specialties. All types of recording are covered, such as writing from pens and stamps, copying from copying machines and printing from printers (laser printers, inkjet printers, and multifunction devices).

The need for ISO 11798 arises from the strong Swedish Archives Act and the necessity for information preservation for the future. The Swedish National Archives’ technical regulations (RA-FS 2006:4) align with the Archive Law and require archival permanence for documents to be preserved in archives. Accordingly, ISO 11798 has been implemented as specification requirements in these regulations.

RISE (formerly SP) has been testing the permanence and durability of paper since the early 1900s and subsequently also the writing on paper, focusing on properties crucial for the durability of writing. As new writing and printing methods have been introduced to the market, testing methods have been adapted to evaluate new properties.

Documents with writing, printing or copying that meet the standard’s requirements are permanent, provided they are stored in an archival environment and produced in combination with permanent paper (in accordance with ISO 9706 or ISO 11108) as substrate.

Purpose

The purpose of the standard is to ensure that archival documents are readable and durable both now and in the future. The documents should withstand long-term storage, be able to be copied, scanned, and handled without being destroyed, and endure some exposure to light, water, and heat. Additionally, the writing and printing (and the process of printing for laser printers) must not negatively affect the paper’s strength.

Products tested according to ISO 11798 and meeting the requirements can be certified by RISE.

The permanence and durability of recording on paper produced with writing materials—such as ink from pens and stamp pads—or paper documents produced using equipment like copiers, laser printers, and other types of printers is examined according to ISO 11798. ISO 11798 contains both the testing procedure and requirements that needs to be fulfilled.

The recording is evaluated using various methods, including tensile testing, folding endurance, optical density, color change (for color printers), and abrasion.

The standard specifies requirements in the form of:

• Appearance of the recording
• Lightfastness
• Water resistance
• Transfer of writing to adjacent documents when stacked
• Abrasion resistance
• Heat resistance
• Effect of writing on the mechanical strength of the paper
• Effect of the printing process on the mechanical strength of the paper (for laser printers)

The standard also specifies the paper to be used for producing recording (ISO 9706 and ISO 11108).

Accreditation 

The testing activities for recording on paper maintain high quality through accreditation according to SS-EN ISO/IEC 17025:2018.

RISE tests paper for long-term storage in archives; permanent paper (ISO 9706) and archival paper (ISO 11108). Paper that meets the standards' requirements can be certified by RISE and be labeled with the mark "Svenskt arkiv". To create archival documents, permanent or archival paper is required along with permanent writing or printing (ISO 11798).

When talking about archival documents, we refer to documents that can be stored in protected environments for a long time, probably for hundreds of years. Paper that meets the requirements in ISO 9706 is referred to as permanent paper and ISO 11108 is referred to as archival paper (permanent and durable paper). According to the National Archives' technical regulations (RA-FS 2006:4), the paper for permanent documents can be of both types. Archival documents are produced by combining such paper with a permanent writing and printing. Permanent paper is often used as copying paper, while archival paper, which is stronger and made from rag pulp, is used for important documents such as diplomas and certificates. If the documents are expected to be handled in the future, archival paper should be chosen as it is more durable and withstands significantly more handling than permanent paper.

These two types of papers are distinguished from paper tested according to ISO 20494 where the paper stability is intended for general graphic applications. Such paper is not intended for archival storage, and does not have to be permanent, but rather to be durable during its use when used to produce newspapers, brochures etc.

Purpose

The standards are based on providing permanent paper that can be used in the production of archival documents (if the writing and printing is permanent according to ISO 11798)

Permanent paper is evaluated according to ISO 9706 and archival paper (which is permanent and durable) is evaluated according to ISO 11108. RA-FS 2006:4 refers to these two standards for paper testing. The testing includes the following test procedures.

pH - cold water extract 

Acidic paper deteriorates quickly, so pH is an important parameter to measure in paper. Electrolytes are extracted from the paper in a water solution, and the pH value is then measured on this cold water extract.

Alkali reserve 

The formation of acids from air pollutants in the surrounding air or natural ageing is harmful to the paper. Therefore, such paper usually contains some alkaline filler (e.g., calcium carbonate) to prevent acid attacks and neutralize the harmful acids, i.e., the paper has an alkali reserve. The alkali reserve can be measured through a titration process.

Kappa number 

The kappa number indicates the amount of oxidizable material, such as lignin, in the pulp. Since such material can discolor and decompose the paper, the aim is to keep the kappa number low. Accordingly, the paper should only contain a limited amount of oxidizable material. For chemical pulps, the kappa number usually ranges between 1 and 100.

Tear strength 

Tear strength is a measure of the mechanical strength of the paper and indicates the force (mN) required to tear a piece of paper.

Folding strength 

Folding strength is another measure of the mechanical strength of the paper and indicates the strength required to fold a paper strip in a paper folder until it breaks.

Requirements for permanent paper (ISO 9706):

• pH value: between 7.5 and 10.0
• Alkali reserve: at least equivalent to 0.4 mol of acid per kg of paper (at least 2% chalk or equivalent)
• Tear strength: at least 350 mN in the machine and cross direction of the paper
• Kappa number: less than 5

Requirements for archival paper (ISO 11108): 

Archival paper must meet the requirements for permanent paper according to ISO 9706 and additionally;

• Manufacture: must consist of cotton, hemp, or linen but may contain a small amount of bleached chemical pulp
• Grammage: at least 70 g/m²
• Folding strength: at least 2.18 in the machine and cross direction of the paper

Accreditation 

The testing activities for permnent and archival paper maintain high quality through accreditation according to SS-EN ISO/IEC 17025:2018.

Certification 

Certification of durable paper in accordance with RISE certification rules (SPCR 004).

Archive boxes (made of cardboard) and file covers (made of paper) are used for archiving and storing documents. These storage materials are included in the National Archives’ regulations on technical requirements and can be tested according to ISO 16245. The requirements cover strength properties, functionality, and material selection.

Archive boxes and file covers can be tested according to ISO 16245. The requirements cover strength properties, functionality, and material selection. It is important that archive boxes and file covers are tested according to this standard to ensure the preservation of documents printed on permanent paper and with permanent writing or printing. However, the storage materials cannot compensate for poor storage conditions.

There is also a desire to be able to label archive boxes and other storage materials with self-adhesive labels that do not fall off over time or become illegible. RISE also performs this testing according to RA-FS 2006:4, appendix 3, for self-adhesive labels. Adhesion is a central part of this testing, and two different types of archive boxes (or other types of storage media) are used in the testing

Boxes, file covers and other enclosures are tested and evaluated in our laboratory according to ISO 16245.

It is important that the textiles on the market are free of harmful and regulated substances. Chemical analysis is a way to gain control over the products' chemical content.

Society and consumers set high demands on companies and their products. The legislation also means that you as an actor must have complete information and control over the chemicals in your product. It is especially important with products for children and goods with skin contact, such as clothes and accessories.

We can help you interpret the legal requirements in REACH and POPs and propose appropriate analysis.
